Description

Technical Field

[0001] The utility model relates to the technical field of lawn mowers, in particular to a lawn mower with rake teeth. Background Art

[0002] A lawn mower is a mechanical tool used to trim grass and vegetation. It consists of a cutterhead, an engine, wheels, a running mechanism, blades, handrails, and a control system. The cutterhead is mounted on the wheels, which in turn is equipped with an engine. The engine's output shaft is equipped with blades. The blades utilize the engine's high-speed rotation to significantly increase their speed, saving workers time and manpower.

[0003] When weeding in vineyards and other orchards, it is inevitable to cut vines. However, the current lawn mowers cannot gather the vines in the soil, and they simply cut the vines, resulting in the vines being still large in size. After weeding, the vines in the soil need to be sorted separately, otherwise it will affect the later growth of plants and increase the intensity of labor. Therefore, we proposed a lawn mower with rake teeth to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that vines are inevitably cut when weeding in vineyards and other orchards, and the current lawn mowers cannot gather the cut vines. After weeding, the vines in the soil need to be sorted separately, which increases the labor intensity. A lawn mower with rake teeth is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A lawn mower with rake teeth comprises a frame, a rear suspension provided on one side of the frame, a cutter shaft provided inside the frame, a hoe blade arranged in a spiral line mounted on the cutter shaft, a hood frame provided above the cutter shaft, the hood frame fixed to the frame, and a channel steel fixed blade adapted to the hoe blade fixed to the bottom surface of the hood frame;

[0007] A crossbeam is provided on one side of the knife shaft, and a plurality of rake teeth are linearly arranged on the crossbeam. The rake teeth are inclined toward the knife shaft, and a roller is provided on the side of the crossbeam away from the knife shaft. The roller is rotatably mounted on the frame.

[0008] As a preferred technical solution of the present invention, a cover plate is provided between the hood frame and the crossbeam, one side of the cover plate is hingedly connected to the hood frame, and the other side of the cover plate is overlapped on the crossbeam, so that the knife shaft can be cleaned conveniently by opening the cover plate.

[0009] As a preferred technical solution of the present invention, the hood frame is arranged in multiple sections, and reinforcing ribs are provided on the inner wall of the hood frame to improve the strength of the hood frame, thereby improving the stability of the hoe blade when it cooperates with the channel steel fixed blade.

[0010] As a preferred technical solution of the present invention, a baffle is provided on the side of the blade shaft away from the crossbeam. The number of the baffles is ten to twenty, and the baffle hinge is installed at the bottom end of the hood frame to block the soil splashed when the grass is broken.

[0011] As an optimal technical solution of the present invention, a gear box for driving the cutter shaft is provided on the rear suspension, a rotating shaft is provided on one side of the gear box, a pulley is provided on the other end of the rotating shaft, and a pulley is also installed on the outer end of the cutter shaft. The pulleys are connected by a V-belt, and the gear box is connected to an external drive vehicle.

[0012] As an optimal technical solution of the present invention, the rake teeth are slidably matched with the crossbeam, and each rake tooth is provided with a plurality of through holes, one of which is provided with a detachable limit pin. By pulling out the limit pin, the insertion height of the rake teeth can be adjusted, and vines at different depths in the soil can be raked up and gathered.

[0013] As a preferred technical solution of the present invention, two guide rails are provided on the frame, and the rear suspension is slidably mounted on the guide rails, which are hung on the tractor. The guide rails can slide and can be adjusted to adapt to mowing operations in different positions.

[0014] The beneficial effects of the utility model are:

[0015] 1. By arranging rake teeth on the mower, the cut vines can be raked and gathered by the rake teeth. After the vines are gathered, the vines can be broken up in the mower by a hoe to reduce the volume of the vines, avoiding the need to sort the vines separately in the later stage, and the plants can be planted directly, thereby reducing the labor intensity of the operator.

[0016] 2. By arranging multiple hoe blades arranged in a spiral line and matching channel steel fixed blades, the weed-breaking effect is improved through their mutual cooperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 A lawn mower with rake teeth includes a frame 1, a rear suspension 10 is provided on one side of the frame 1, the front end of the rear suspension 10 is the front suspension, the rear suspension 10 is connected to an external drive vehicle body, two guide rails are provided on the frame 1, the rear suspension 10 is slidably mounted on the guide rails, the rear suspension 10 is hung on a tractor, the guide rails can slide, and can be adjusted to adapt to mowing operations in different positions, a cutter shaft 2 is provided inside the frame 1, and a gear box 12 for driving the cutter shaft 2 is provided on the rear suspension 10, a rotating shaft is provided on one side of the gear box 12, a pulley is provided on the other end of the rotating shaft, and a pulley is also provided on the outer end of the cutter shaft, the pulleys are connected to each other by a V-belt, and the gear box 12 is connected to a driving part in the external drive vehicle;

[0024] Among them, the hoe blade 3 arranged in a spiral line is installed on the knife shaft 2, and a hood frame 8 is set above the knife shaft 2. The hood frame 8 is fixed on the frame 1, and a channel steel fixed blade 9 adapted to the hoe blade 3 is fixed on the bottom surface of the hood frame 8. The hood frame 8 is arranged in multiple sections, and the inner wall of the hood frame 8 is provided with reinforcing ribs to improve the strength of the hood frame 8, thereby improving the stability of the hoe blade 3 when it cooperates with the channel steel fixed blade 9;

[0025] Secondly, a crossbeam 5 is provided on one side of the cutter shaft 2, and a plurality of rake teeth 7 are linearly arranged on the crossbeam 5. The rake teeth 7 are inclined toward the cutter shaft 2, and the rake teeth 7 slide in cooperation with the crossbeam 5. Each rake tooth 7 is provided with a plurality of through holes, and a detachable limit pin is inserted into one of the through holes. The insertion height of the rake teeth 7 can be adjusted by pulling out the limit pin, and vines of different depths in the soil can be raked up and gathered, and a roller 6 is provided on the side of the crossbeam 5 away from the cutter shaft 2, and the roller 6 is rotatably mounted on the frame 1.

[0026] It should be noted that a cover plate 4 is provided between the hood frame 8 and the crossbeam 5, and a handle is installed on the cover plate 4. One side of the cover plate 4 is hingedly connected to the hood frame 8, and the other side of the cover plate 4 is overlapped on the crossbeam 5. By opening the cover plate 4, it is convenient to clean the knife shaft 2.
