The working principle of the lawn mower


     lawn mowerPrinciple: Comb-tooth rotating bevel gear speed-increasing transmission mechanism and comb-tooth profiling depth adjusting device group; The bearing seats under the cross beams on both sides of the frame support the front and rear shaft driven bevel gear speed-increasing transmission mechanism directly driven by the ground wheel. The axial center line of the front and rear comb teeth is located directly above the longitudinal direction of the large-length double seedling eye or the small-length single seedling eye, and each set can be configured with 6 to 10 groups. The left and right wing hoe shovels and comb teeth are correspondingly installed on the front beam; compared with manual weeding, the weeding machine of this structure has an efficiency increase of 8 to 10 times, and the seedling injury rate and average cleaning rate are lower. The foam filter element should be cleaned every 25 hours, and the dust should be more frequent. The foam filter element is cleaned with kerosene or washing liquid and clean water, and then squeezed and dried. The paper filter element is cleaned every 25 hours, especially when the dust is large. Use the front air filter, clean the front filter every 25 hours, and clean the paper core every 100 hours. Dust should be more frequent. The cleaning of the front air filter is the same as that of the foam filter element. The paper filter element should be knocked on the plane.

 

割草机的工作原理

 

The lawn mower is simple to operate, has a strong ability to cut objects, and is mainly grass, suitable for high-yield pastures and large parks. The lawn mower mows grass through the relative shearing movement of the moving knife and the fixed knife on the knife. It has the characteristics of neat cutting stubble, low power requirements, poor adaptability to pasture, and easy blockage. It is suitable for flat natural grassland and artificial grassland operations. Rotary lawn mowers were produced and used in the mid-1980s. Grass is mowed by the impact of the blade on the high-speed rotating cutter head. With the advancement of science and technology, the working capacity and speed of the newly improved lawn mower products have been greatly improved, saving the working time of weeding workers and saving a lot of human resources.
An adjustable lawn mower used for ridge cultivation, which is composed of a parallel four-bar lifting device, a frame, a left and right wing weeding device, a whole machine deflection adjustment device, a comb-tooth rotating bevel gear speed-increasing transmission mechanism and a comb-tooth profiling depth adjustment device. The bearing seats under the crossbeams on both sides of the frame support the front and rear axle active bevel gear speed-increasing transmission mechanism directly driven by the ground wheel. The axial center lines of the front and rear combs are located longitudinally directly above the large-length double seedling eye or the small-length single seedling eye, and each group can be configured with 6-10 groups. The left and right wing hoes and combs are correspondingly installed on the front crossbeam. Compared with manual weeding machine of this structure, seedling rate is higher.
When the cutter head rotates at a high speed, the blade hinged on the cutter head of the rotary lawn mower maintains its cutting state under the action of centrifugal force. When the resistance is too large or an obstacle is encountered, the blade will swing backward to avoid damage. After one edge of the blade is worn, it can be replaced for use. Replacement of blades is also more convenient than reciprocating mowers. On the rotary lawn mower, in addition to the safety device similar to the reciprocating lawn mower, a protective cover is added above the knife to ensure personal safety. The rotary lawn mower mows grass by the blade hitting the high-speed rotating cutter head. The cutting speed (peripheral speed of the blade root) is as high as 6090 m/s, the work is stable, and the working speed can reach more than 15 km/h. It has the characteristics of strong adaptability to forage and is suitable for high-yield forage. However, the cutting is not neat enough, heavy cutting is more, and the power required per unit cutting width is larger.

How to maintain planter accessories

Planter A planting machine using crop seeds as a planting object. Planters for a certain type or crop are usually named after the crop type, such as wheat planter, cotton planter, etc. Planter accessories are very effective in farmland operations, so the planter accessories are easily damaged. Next, the planter manufacturer will introduce how to maintain the planter accessories. Before using the planter, we should have a simple and comprehensive understanding of the principles of all planter accessories. The planter manufacturer stated that it can be effective as long as the maintenance is carried out on the correct accessories to ensure the normal use of the planter accessories. The planter will extend its life.


Defects in castings and forgings

The defects produced in the casting and forging process are similar to the defects produced in the ingot, but they are still process defects, including pores, inclusions, shrinkage holes, loose holes, cracks, etc.


Production of castings and forgings

Castings and forgings must be melted by electric furnaces, mainly electric arc furnaces and induction furnaces. According to the different lining materials and slag system, can be divided into acidic furnace and alkaline furnace. Carbon steel and low alloy steel can be smelted in any furnace, but high alloy steel can only be smelted in alkaline furnaces.


Inspection of Casting and Forging

The complex information system management interface of casting and forging, such as poor ultrasonic penetration, coarse grain, uneven organization, etc., all enhance the scattering of an ultrasonic wave by students, and the energy can be effectively attenuated, so that the detectable thickness is smaller than that of forgings.


What are the advantages and disadvantages of casting and forging

One of the advantages of casting and forging is the flexibility of design. Personnel design has a large degree of freedom of design choice for the shape and size of castings, especially for parts with complex shapes and hollow sections. Steel castings can be manufactured using a unique process known as core assembly.
