Description

Technical Field

[0001] The utility model relates to the technical field of weeders, in particular to a weeding device for mulberry orchards. Background Art

[0002] A mulberry orchard is an agricultural park specifically for planting mulberry trees and raising silkworms. To ensure the healthy growth of mulberry trees, workers need to carry out weeding work to remove weeds in the planting area. These weeds will compete for nutrients and water in the soil, which will have an adverse impact on the growth of mulberry trees. By removing weeds in a timely manner, the growth environment of mulberry trees can be effectively improved, the competition pressure of weeds on the growth of mulberry trees can be reduced, thereby promoting the healthy growth of mulberry trees and providing sufficient mulberry leaf resources for the breeding of silkworms.

[0003] A weeding machine for forestry engineering including a connecting device is disclosed in the Chinese utility model patent with the publication number of CN221381806U, which includes a driving machine, a transmission pipe, a baffle and a cutting blade. The output shaft of the driving machine passes through the transmission pipe and is rotatably connected to the cutting blade. A horn-shaped frame is arranged on the transmission pipe. The driving machine drives the cutting blade to rotate. Workers hold the horn-shaped frame and control the position of the cutting blade to cut weeds.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: during the use of the above device, workers must continuously hold the horn-shaped frame to ensure the correct position of the cutting blade, which results in a relatively large labor intensity. After long-term operation, the worker's arm will feel sore and fatigued, which is difficult to ensure the accuracy of the cutting blade position. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides a weeding device for mulberry orchards.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a weeding device for mulberry orchards includes a mounting base, a semi-circular protective cover is arranged on the mounting base, a driving motor is vertically arranged on the top of the mounting base, the output shaft of the driving motor passes downward through the mounting base and is provided with a cutter head, a mounting frame is vertically slidably arranged on the protective cover, rolling wheels are arranged on both sides of the mounting frame, a shock-absorbing component for damping the rolling wheels is arranged on the mounting frame corresponding to the rolling wheels, an adjusting component for adjusting the sliding of the mounting frame is also arranged on the protective cover, and an inclined control rod is arranged at the rear of the mounting base.

[0007] By adopting the above technical solutions, an installation base, a protective cover, a driving motor, an installation frame, rolling wheels, a shock-absorbing assembly, and an adjusting assembly are provided. With the installation frame and the rolling wheels, the operator only needs to control the advancing direction through the control rod, without continuously holding the horn-shaped frame to ensure the correct position of the cutting knife, reducing the labor intensity of the operator; the adjusting assembly is used to adjust the lifting of the installation frame, driving the position of the rolling wheels to change, so that the distance between the cutter head and the ground can be adjusted according to the situation of the weeds. The shock-absorbing assembly increases the running stability of the device on bumpy ground, ensuring that the cutter head can accurately cut the weeds.

[0008] Further, the shock-absorbing assembly includes two fixed plates vertically arranged at intervals on one side of the installation frame. A first slide rail is vertically arranged between the two fixed plates on the side surface of the installation frame. A sliding seat is slidably arranged on the first slide rail. The sliding seat is rotatably connected to the axle of the rolling wheel. A mounting plate is horizontally arranged on one side of the sliding seat. A spring is arranged between the mounting plate and the upper fixed plate. The upper end of the spring is connected to the upper fixed plate, and the lower end is connected to the mounting plate.

Detailed Description of the Embodiment

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0027] Such as Figures 1-4As shown, the present invention discloses a sericulture garden weeding device, comprising a mounting base 10, a drive motor 12, a mounting frame 20, rolling wheels 21, a shock-absorbing assembly 30, and an adjustment assembly 40. The drive motor 12 is vertically mounted on the top of the mounting base 10. The output shaft of the drive motor 12 passes downward through the mounting base 10 and is provided with a cutter disc 13. The drive motor 12 drives the cutter disc 13 to rotate and cut weeds. A semicircular protective cover 11 is provided on the mounting base 10 to prevent weeds chopped by the cutter disc 13 from splashing onto the operator, thus protecting them. The mounting frame 20 slides vertically on the protective cover 11. Rolling wheels 21 are provided on both sides of the mounting frame 20. With the mounting frame 20 and rolling wheels 21, the operator only needs to control the forward direction using a control lever 50, eliminating the need to constantly hold the horn frame to ensure the cutting blade is at the correct height, thus reducing the operator's workload. A shock-absorbing assembly 30 is provided on the mounting frame 20, corresponding to the rolling wheels 21, to reduce vibrations and increase the stability of the device on bumpy terrain. The protective cover 11 is also equipped with an adjustment assembly 40 for adjusting the sliding movement of the mounting bracket 20, which drives the position of the roller 21 to change, allowing the distance between the cutting disc 13 and the ground to be adjusted according to the weed situation. An inclined control lever 50 is provided on the rear side of the mounting bracket 10 to control the forward movement of the device.

[0028] Specifically, the control rod 50 includes a first connecting rod 51 and a second connecting rod 52. The first connecting rod 51 is connected to the mounting base 10. The second connecting rod 52 is provided with a connecting tube 53. The first connecting rod 51 is slidably disposed within the connecting tube 53. By sliding the first connecting rod 51 within the connecting tube 53, the overall length of the control rod 50 can be adjusted according to the height and usage habits of the staff. A fixing assembly 60 is provided on the connecting tube 53 for fixing the adjusted first connecting rod 51. The first connecting rod 51 is provided with a plurality of fixing holes 55 spaced apart along its length. The fixing assembly 60 includes a third threaded rod 61 screwed onto the connecting tube 53 through the threaded hole. The inner end of the third threaded rod 61 is placed in one of the fixing holes 55. The core direction of the third threaded rod 61 is perpendicular to the length direction of the connecting tube 53. The third threaded rod 61 is rotated so that the end of the third threaded rod 61 is disengaged from the fixing hole 55. The first connecting rod 51 is then slid and adjusted to a suitable position. The screw cap 62 is then rotated so that the end of the third threaded rod 61 enters the corresponding fixing hole 55 to fix the first connecting rod 51. The outer end of the third threaded rod 61 is provided with a screw cap 62 to facilitate the staff to rotate the third threaded rod 61.

One end of the worm 45 is provided with a screwing handle 46, which is convenient for the staff to rotate the worm 45.

[0030] The shock-absorbing assembly 30 includes two fixing plates 31 vertically arranged at intervals on one side of the mounting frame 20. A first slide rail 32 is vertically arranged between the two fixing plates 31 on the side of the mounting frame 20. A sliding seat 33 is slidably arranged on the first slide rail 32. The sliding seat 33 is rotatably connected to the wheel axle of the rolling wheel 21. A mounting plate 34 is horizontally arranged on one side of the sliding seat 33, so that the rolling wheel 21, the sliding seat 33 and the mounting plate 34 slide synchronously on the first slide rail 32. A spring 35 is arranged between the mounting plate 34 and the upper fixing plate 31. The upper end of the spring 35 is connected to the upper fixing plate 31 and the lower end is connected to the mounting plate 34. A hydraulic damper 36 is also arranged on the mounting plate 34. The lower end of the storage oil cylinder of the hydraulic damper 36 is connected to the mounting plate 34 and the upper end of the piston rod is connected to the upper fixing plate 31. When encountering uneven land, the rolling wheel 21 slides relative to the mounting frame 20 along the first slide rail 32, so that the sliding seat 33 and the mounting plate 34 slide up and down synchronously. The combined action of the hydraulic damper 36 and the spring 35 plays a role in shock-absorbing the rolling wheel 21, reducing the influence of uneven land on the mounting seat 10 and the cutter head 13 during the weeding process.

[0031] During specific setting, a horizontally arranged sliding plate 37 is slidably arranged on the first slide rail 32 through a slider. A vertically arranged first threaded rod 38 is spirally arranged on the upper fixing plate 31 through a threaded hole. A rotating handle 39 is arranged at the top of the first threaded rod 38. The lower end of the first threaded rod 38 is rotatably connected to the sliding plate 37. Rotating the rotating handle 39 drives the first threaded rod 38 to rotate, thereby driving the sliding plate 37 to slide. The upper end of the spring 35 is connected to the sliding plate 37, and the upper end of the piston rod of the hydraulic damper 36 is connected to the sliding plate 37. The sliding plate 37 moves up and down, changing the length of the spring 35 in the initial state, thereby changing the pressure of the spring 35 in the initial state, and further changing the shock absorption effect on the rolling wheel 21, so that the shock absorption effect of the shock absorption assembly 30 can be adjusted according to the flatness of the land to achieve the best stability effect.

[0032] In this embodiment, the working principle of a mulberry orchard weeding device is as follows: When weeding, first rotate the screwing handle 46 to drive the worm 45 to rotate, thereby driving the worm wheel 44 to rotate, and then driving the second threaded rod 43 to rotate, so that the mounting frame 20 moves up and down to adjust the position of the rolling wheel 21. Then rotate the first threaded rod 38 to make the sliding plate 37 move up and down, change the length of the spring 35 in the initial state, and change the shock absorption effect on the rolling wheel 21. Then start the drive motor 12 to drive the cutter head 13 to rotate. Finally, hold the control handle 54 and push forward to cut the weeds.

[0033] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
