[0017] In order to illustrate the technical solution described in the present utility model, the following is illustrated through specific embodiments.
[0018] For the convenience of description, only the parts related to the embodiments of the present utility model are shown.
[0019] Combined with Figures 1-3As shown in the figure, the agricultural weeding machine includes a trolley 1, a height-adjusting bracket 2 is provided on the trolley 1, a pair of guide rail brackets 3 are provided inside the height-adjusting bracket 2, a tool rest 4 is slidably provided on the guide rail brackets 3, a hob shaft 5 is rotatably provided at the bottom of the tool rest 4, a weeding assembly is provided on the hob shaft 5, a detachable grass collection hopper 6 is provided on the trolley 1 facing the weeding assembly, an adjusting assembly for adjusting the up and down movement of the tool rest 4 is provided on the height-adjusting bracket 2, the adjusting assembly includes an adjusting screw rod 7 and an adjusting nut 8 which are respectively rotatably installed on the adjusting bracket 2 and the tool rest 4, the adjusting screw rod 7 is located inside the adjusting nut 8, and a driving mechanism for driving the hob shaft 5 to rotate is further provided on the trolley 1.
[0020] In the daily management process of crop planting, weeding is an important operation process. Appropriate weeding can not only promote the healthy growth of crops, but also play a role in beautifying the fields.
[0021] Before using this weeding machine for weeding work, the height of the weeding assembly can be finely adjusted according to requirements. When it is necessary to adjust the weeding height of the weeding assembly, only need to turn the nut on the adjusting screw rod, the adjusting screw rod will rotate, during which the adjusting nut will drive the tool rest to move vertically, and at the same time, both sides of the tool rest will slide vertically in the guide rail brackets until the whole weeding assembly is lifted or lowered to the required weeding position.
[0022] In the above structure, the vertical adjustment of the weeding assembly is completed only by turning the adjusting screw rod, and the whole adjustment process is relatively simple and fast. And under the guidance and limitation of the guide rail brackets, the whole adjustment process is relatively stable.
[0023] As a preferred structure, as Figures 1-2 , the trolley 1 includes a push frame 1.1, a front wheel 9 and a rotating shaft 10 are respectively rotatably provided at the front and rear of the push frame 1.1, rear wheels 11 are provided at both ends of the rotating shaft 10, an intermediate gear 12 and an output gear 13 are rotatably provided on the push frame 1.1, an input gear 14 is provided on the rotating shaft 10 and the input gear 14, the intermediate gear 12 and the output gear 13 are meshed and installed with each other, a driven sprocket 15 is provided on the shaft rod of the output gear 13, the driving mechanism includes a driven pulley 16 and a driving sprocket 17 which are respectively installed on the hob shaft 5, a driving motor 18 is further provided on the push frame 1.1, a driving pulley 19 is provided on the driving shaft of the driving motor 18, a belt 20 is sleeved between the driving pulley 19 and the driven pulley 16, and a chain 21 is sleeved between the driven sprocket 15 and the driving sprocket 17. The trolley 1 further includes a handrail 22.
[0024] When the weeding component is adjusted, the staff can carry out the weeding operation. When the staff uses this weeding machine for weeding, first start the driving motor. When the driving motor starts to work, it drives the driving pulley to rotate. Under the linkage of the belt, the driven pulley rotates, and the hob shaft rotates synchronously. During the rotation of the hob shaft, it drives the weeding component, thus completing the weeding task. And the driving sprocket rotates synchronously with the hob shaft. Under the linkage of the chain, the driven sprocket also rotates, and the output gear rotates with the driven sprocket. Finally, under the linkage of the input gear, the rotating shaft rotates, and at this time the rear wheels rotate and the cart moves forward.
[0025] Therefore, when the staff uses this weeding machine for weeding, they only need to hold the armrests with both hands and use the driving mechanism to drive the weeding component to rotate to complete the weeding task. At the same time, when the driving mechanism drives the weeding component to carry out weeding, under the above series of linkages, the driving mechanism also drives the two rear wheels to rotate, so that the cart moves forward. In this way, when the staff uses the weeding machine for weeding, they only need to hold the armrests, which makes the whole weeding task easier.
[0026] In this structure, as Figure 3 , an outer cover 23 is also provided on the cart 1, and both sides of the armrest 22 pass through the outer cover 23. On the one hand, the outer cover can make this weeding machine look more beautiful. On the other hand, it also plays a certain safety role.
[0027] In the above structure, as Figures 1-2 , the push frame serves as the carrier of this weeding machine, and a box body 24 is also provided on the push frame. The intermediate gear 12, the output gear 13 and the input gear 14 are all rotatably installed in the box body 24.
[0028] In this weeding machine, as Figure 2 , the weeding component includes three hob disks 25 evenly installed on the hob shaft 5. A number of hobs 26 are jointly provided on the hob disks 25, and the hobs 26 are evenly arranged.
[0029] In this structure, three hob disks are provided on the hob shaft. The hob disks serve as the installation carriers of the hobs. A circle of hobs is jointly provided on the three hob disks. When the driving mechanism drives the weeding component to rotate, the hob shaft will drive the three hob disks to rotate synchronously, and all the hobs will rotate together, so as to achieve the purpose of weeding.
[0030] Further, as a preferred structure, as Figure 1, an avoidance opening is formed in the trolley 1, and support plates 27 are arranged on both sides of the grass collection hopper 6, with a short rear plate 28 provided at the rear. Round holes are formed in the support plates 27, and a pair of limit short columns 29 are arranged on the trolley 1. The grass collection hopper 6 is located within the avoidance opening, and the corresponding positions of the trolley 1 respectively support the support plates 27 and the short rear plate 28, and the limit short columns 29 pass through the round holes on the same side.
[0031] In actual situations, a top cover 30 is rotatably arranged at the top of the outer cover 23 corresponding to the position of the grass collection hopper. During the weeding process of the weeding assembly, the chopped weeds will be thrown towards the grass collection hopper. The grass collection hopper serves to collect the chopped grass, and the grass collection hopper can be used to clean the weeds in a timely manner, avoiding the weeds being blown away by the wind and causing environmental pollution.
[0032] When the staff is performing the weeding work, the grass collection hopper should be taken out regularly to dump the chopped grass inside. After dumping is completed, the grass collection hopper is then installed in the avoidance opening as required. When installing the grass collection hopper, first, the hopper opening of the grass collection hopper is arranged towards the weeding assembly, and then the grass collection hopper is placed into the avoidance opening until the support plates and the short rear plate respectively fall on the corresponding positions of the trolley. At the same time, the limit short columns all pass through the round holes on the support plates on the same side. The limit short columns play a role in relation to the grass collection hopper.
[0033] 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, and improvements made within the spirit and principles of the utility model shall be included within the protection scope of the present utility model.
