Technical Field

[0001] The utility model relates to the technical field of weeding machines, and particularly to a weeding machine for citrus tree planting areas. Background Art

[0002] Many citrus trees are planted in hilly areas with few flat lands. Therefore, many citrus trees are planted on convex or concave slopes with large areas. Due to the large slope of the slopes, large weeding equipment cannot directly go up the slopes for mowing, such as the weeding machine driven by a tractor; small weeding machines need to be pushed manually for movement, but small weeding machines are close to the ground and are only suitable for mowing the turf in family yards. When mowing on slopes, they are easily stuck and the weeding efficiency is low; moreover, there are many hard soil clods or stones on the slopes, which are likely to damage the blades. Therefore, it is necessary to solve these problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0028] As Figures 1 to 4 shown, a weeding machine for citrus tree planting land includes a mounting frame 1, an engine 2, a vehicle frame 3 and a blade 4. Rotatable first wheels 5 are connected to both ends of the vehicle frame 3. The mounting frame 1 is fixedly placed at the upper end of the vehicle frame 3, and the engine 2 is fixedly placed on the mounting frame 1; A handrail 6 is provided above the engine 2, and the handrail 6 is connected to the upper end of the vehicle frame 3;

[0029] Above the frame 3, a connecting pipe 7 is provided. One end of the connecting pipe 7 is fixedly connected to the mounting bracket 1, and a connecting head 8 is fixedly connected to the other end of the connecting pipe 7. A rotatable first transmission shaft is arranged in the connecting pipe 7. One end of the first transmission shaft passes through the mounting bracket 1 and is connected to the output end of the engine 2. The other end of the first transmission shaft extends into the connecting head 8 and is sleeved with a first gear. A second transmission shaft 9 is arranged in the connecting head 8. A second gear is sleeved on the upper end of the second transmission shaft 9, and the second gear meshes with the first gear. The blade 4 is placed at the lower end of the connecting head 8, and the blade 4 is sleeved on the lower end of the second transmission shaft 9.

[0030] A protective plate 10 is arranged at the upper end of the blade 4, and the protective plate 10 is fixedly connected to the connecting head 8.

[0031] When this embodiment is applied, first, the frame 3 is pushed through the first wheel 5 by the armrest 6 to move, and the weeding machine enters the citrus tree planting land. The engine 2 is started, and the output end of the engine 2 drives the first transmission shaft to rotate. The first transmission shaft drives the second transmission shaft 9 to rotate through the first gear and the second gear. During the rotation of the second transmission shaft 9, the blade 4 is driven to rotate, and when the blade 4 rotates, the grass on the citrus tree planting land is cut.

[0032] In this embodiment, the first wheel 5 is large in size, so that the frame 3 has a high ground clearance, can effectively adapt to the citrus tree planting land with a large slope, and can effectively improve the moving efficiency of the weeding machine. By rotating the armrest 6 and adjusting the height of the armrest 6, the ground clearance of the blade 4 can be adjusted, thereby improving the mowing efficiency of the blade 4. When the blade 4 is mowing grass, the protective plate 10 moves along with the blade 4 to protect the blade 4, and can prevent hard soil blocks or stones from damaging the blade 4 and extend the service life of the blade 4.

[0033] In the above embodiment, both ends of the armrest 6 are respectively fixedly connected to both sides of the upper end of the frame 3 through two connecting sleeves 11.

[0034] In this embodiment, the frame 3 and the armrest 6 are connected through two connecting sleeves 11, which can increase the height of the armrest 6, facilitate the adjustment of the horizontal height of the blade 4, and also facilitate the operation of the weeding personnel.

[0035] In the above embodiment, a connecting member 12 is fixedly arranged on the connecting pipe 7, and both ends of the connecting member 12 are respectively fixedly connected to both ends of the frame 3 through two structural pipes 13.

[0036] In this embodiment, the connecting pipe 7 is fixedly connected to both ends of the frame 3 through the connecting member 12 and two structural pipes 13, which improves the fixing strength of the connecting pipe 7 and the stability of the weeding machine.

[0037] In the above embodiments, a connecting rod 14 is fixedly arranged on the connecting pipe 7, and the connecting rod 14 is located between the connecting member 12 and the connecting head 8; a rotatable second wheel 15 is arranged at the lower end of the connecting rod 14.

[0038] In this embodiment, the second wheel 15 is fixedly connected to the connecting rod 14, which improves the moving efficiency of the weeding machine and forms a three-point support with the two first wheels 5, enhancing the stability of the weeding machine during movement. The support of the second wheel 15 and the connecting rod 14 on the connecting pipe 7 can prevent the blade 4 from contacting the ground when mowing grass, ensuring the mowing efficiency of the blade 4.

[0039] In the above embodiments, a bearing is sleeved on the second transmission shaft 9, and the second transmission shaft 9 is rotatably connected to the inner wall of the connecting head 8 through the bearing; a bushing 16 is fixedly arranged at the lower end of the connecting head 8, the blade 4 is located at the lower end of the bushing 16, a cutter head cover 19 is arranged at the lower end of the blade 4, and the lower end of the second transmission shaft 9 passes downward through the bushing 16, the blade 4 and the cutter head cover 19 and is connected to a nut 18.

[0040] In this embodiment, the blade 4 is limited by the bushing 16, the cutter head cover 19 and the nut 18, so that the blade 4 rotates in a limited manner between the bushing 16 and the cutter head cover 19. The second transmission shaft 9 drives the blade 4 to rotate, and the blade 4 has a high rotation efficiency and a high mowing efficiency.

[0041] In the above embodiments, both the protection plate 10 and the blade 4 are circular, and the diameter of the protection plate 10 is larger than that of the blade 4.

[0042] In this embodiment, the diameter of the protection plate 10 is larger than that of the blade 4, which can effectively push hard lumps of soil or stones away from the blade 4, protect the blade 4, extend the service life of the blade 4, and improve the mowing efficiency of the blade 4.

[0043] In the above embodiments, a plurality of grooves 17 are arranged on the protection plate 10. One end of each of the plurality of grooves 17 communicates with the edge of the protection plate 10, and the other end is close to the center of the protection plate 10. The distance between every two adjacent grooves 17 is equally spaced.

[0044] In this embodiment, during the process of the blade 4 mowing grass, the edge of the protection plate 10 presses down on the grass. Some grass is relatively soft and is not easily cut off after being pressed down by other grass; the use of the plurality of grooves 17 enables some grass to pass through the edge of the protection plate 10 and enter the grooves 17, and the blade 4 cuts the grass that enters the grooves 17, which can improve the efficiency of cutting relatively soft grass and thus improve the mowing efficiency.

[0045] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
