Classification of lawn mowers


lawn mowerIt is composed of cutter head, engine, walking wheel, walking mechanism, blade, handrail and control part. It consists of a parallel four-bar lifting device, a frame, a left and right wing weeding device, a complete machine deflection adjustment device, a comb-tooth rotating bevel gear speed-increasing transmission mechanism and a comb-tooth profiling depth adjustment device. Compared with artificial weeding, the efficiency is increased by 8-10 times, the seedling injury rate is low, and the seedling clearing rate is high.

According to different classification standards, lawn mowers can be divided into the following types:
1. According to the driving: intelligent semi-automatic towing type, push type, installation type, tractor suspension type.
2. According to power: human and animal power drive, engine drive, electric drive and solar drive.
3. It is divided into hob type, rotary cutter type, side hanging type and flying knife type.
4. According to the requirements, it is divided into: flat type, half waist type and truncated type.
Hand-held rotary mowers are generally equipped with bladeless cutting discs, using high-strength nylon ropes as forage cutting components. It has a flexible structure, is not afraid of rigid obstacles, is safe to use, and is easy to replace. The working mode of the lawn mower is reciprocating and rotary. It has high mowing efficiency, greatly saves time, realizes the functions of environmental protection and beautification, and is simple, convenient, efficient, and widely used. The machine is small in size and suitable for small and medium lawns. When using the lawn mower, the stubble height should be determined according to the requirements, which is very convenient to use. Mowing grass can only be cut laterally along the slope, not along the slope. Modern lawn mowers are more convenient to operate.
Rotary lawn mowers rely on the high-speed rotation of the blade to mow the grass. If the linear speed of the blade is not enough, the effect of mowing is not good. So when mowing, use a big throttle, high speed. In addition, the carburetor and automatic speed regulating device of the lawn mower make the fuel consumption of the lawn mower very low if there is no load when the throttle is large. Only when it is fully loaded, its speed will change from 3400r.p.m. when it is unloaded. Reaching 2800r.p.m, so there is no need to use a small throttle to save fuel, and the mowing effect is not good.
According to the requirements of the lawn, the height of stubble after mowing should be determined, and the mowing height should be 1/3 the height of the original grass. Due to the special structure of the lawn mower, mowing can only be carried out horizontally along the slope, not up and down the slope. Be especially careful when turning in special places such as slopes, beware of obstacles in caves, trenches, mounds and other grass. The new cart-type lawn mower is no longer a back-type lawn mower. When you mow, you carry a backpack/side-mounted lawn mower on your back, and you will be tired in a few minutes. The hand-changing self-pushing lawn mower is convenient, light and flexible, and is used to harvest wheat, rice, beans, shrubs, reeds, highland barley, alfalfa, fish grass and other crops., Regardless of the size of the field such as plains, hills, terraces, triangles and muddy. Simple operation, high work efficiency, can cut an acre of land per hour, can be carried by one person.

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.
