Description

Knife-type lawn mowing device with grass turning plate

Technical field:

The invention relates to the field of agricultural machinery and equipment, in particular to a knife-type mowing device with a grass picking wheel.

Background technique:

The working method of the knife lawn mower is the process of cutting the weeds from the root position by driving the horizontal lawn mower along the ground surface by the locomotive. It has the characteristics of fast speed, high efficiency and smooth grass surface, and it is widely used. However, this type of mowing method has a drawback. When the weeds are cut, they are still in the original position, and when the weeds are relatively dense, most of the weeds after cutting will not fall down, and even the cuts of the grass stalks are still in place. Cut on the rhizome. In this case, the vitality of some weeds is relatively tenacious. Because the water supply to the cut-off mouth is not completely cut off, and the upright growth form is not affected, it will not wither quickly. After cultivation, it will Survive and take root. On some land with sufficient water content, such as paddy fields and woods, the surface water is relatively sufficient. Under the supply of water, the unfallen weeds can re-root and survive without long time. Grass work becomes useless.

The biggest reason for the above problems is that after the weeds are cut by the blades of the knife mower, the whole grass body has not fallen or has not shifted, resulting in no serious changes in the growth conditions of the weeds, as long as there is water supply Can continue to grow.

Summary of the invention:

The purpose of the present invention is to solve the above-mentioned problem of the knife-type lawn mower and provide a knife-type lawn mower with a grass blade. After the weeds are cut by the blade, they will be pulled down or removed by the grass blade, leaving the original The growth position reduces the chance of a second survival.

In order to achieve the above technical objectives, the technical solution adopted by the present invention is to configure and install a grass-pull plate for the knife-type mowing mechanism, and use the turning of the grass-pull plate to knock down or pick up the weeds of the cutting knife of the mowing mechanism to cut After the weeds leave the original position or fall, they lose the opportunity to continue growing.

The knife-type lawn mowing device with a grass-pull plate of the present invention includes a mowing mechanism, a grass-pull plate fixing frame, a gearbox and a grass-pull plate; the mowing mechanism is composed of a knife shaft, a fixing frame and a cutting knife, and is fixed The frame is fixedly arranged on the upper end of the knife shaft, and the cutting knife is fixedly installed on the lower end of the knife shaft; the grass-pull fixing frame includes a chuck and a support plate, and the grass-pull fixing frame is fixedly installed on the knife shaft by the chuck, and the support plate is located Above the cutting knife and arranged parallel to the cutting knife; the gearbox is a gear transmission box, the box body is fixedly installed on the support plate of the grass pad fixing frame, the top is equipped with a power pump, and the bottom is equipped with a drive shaft; The grass tray is installed on the transmission shaft of the gearbox.

The chuck of the grass-pull fixing frame is equipped with a loose piece splint, and the grass-pull fixing frame is fixedly installed on the knife shaft through the chuck and the loose piece splint bolt.

The support plate of the grass pitcher fixing frame is an L-shaped plate body structure, and installation and position adjustment holes are evenly opened along the vertical plate surface.

The gearbox is provided with a fixed rod along the side of the box body, and is installed on the installation and adjustment hole of the support plate of the grass pad fixing frame through the fixed rod.

The grass paddle includes a base and a shift lever; the base is provided with a mounting hole along the center position, and a pole seat is fixedly arranged at the bottom; the shift lever is fixedly installed on the pole seat.

The grass paddle is installed and fixed on the transmission shaft of the gearbox through the mounting hole of the base.

Example 1

The working mode and principle of the knife-type mowing device with the grass-pull plate of the present invention:

The whole device is driven by the tractor. The mowing mechanism 1 is fixedly installed on the frame of the tractor through the fixing frame 12. The knife shaft 11 is set vertically to the ground, and the cutting knife 13 is set horizontally with the ground. After adjusting the height of the cutting knife 13, follow When the tractor moves forward, the cutter 13 cuts the weeds along the ground to complete the mowing operation; the power pump 31 on the gearbox 3 drives the operation through the tractor power unit transmission connection, and the power pump 31 drives the transmission through the gearbox 3 acceleration drive The shaft 32 rotates to drive the grass wheel 4 to rotate. During the rotation of the grass wheel 4, the tilted lever 42 is used to knock down or pick up the weeds cut by the cutter 13 to make the cut weeds leave. Original position or fall.

Existing knife-type lawn mowers, such as the lawn mower 1 of the present invention, after the grass is cut by the cutting knife 13, the weeds will not move significantly, and most of them will remain in the original position, and will not be able to do so when the weeds are relatively dense. Will fall, the mowed grass will only be cut, other growing environment has not changed much, the ground water is sufficient, such as in the woods or paddy fields, will continue to grow, after a period of cultivation will re-root , So that the mowing operation loses its effect or the effect becomes worse. In the present invention, the grass blade 4 is used to displace and dump the mowed grass, so that the growth environment is destroyed and the water supply is lost. Even if the environment is humid, the mowing cannot continue to grow, completely achieving the purpose of mowing.
