[0031] Agricultural production refers to the cultivation of crops, including grain, cotton, oilseed oil, hemp, silk, tea, sugar, vegetables, tobacco, fruit, medicinal herbs, and miscellaneous crops (referring to other cash crops, green manure crops, livestock crops, and other crops). Due to the diverse geographical distribution of plants and animals, as well as regional differences in natural and socioeconomic conditions, a variety of agricultural regions have emerged worldwide. In relatively flat terrain, weeds generally grow faster than crops, necessitating the use of a weeder to control them. A weeder, also known as a lawn mower or lawn trimmer, is a mechanical tool used to trim lawns and vegetation. It consists of a cutterhead, engine, wheels, a running mechanism, blades, handrails, and control components. With advancements in technology, weeders have continued to develop. However, current agricultural weeders lack convenient adjustment of their operating height, resulting in extremely low efficiency when working with weeds of varying heights. Adjusting the weeding blades is also difficult, significantly impacting weed control efficiency.

[0032] In the prior art, a combing tooth is installed at the front end of the cart. During the movement of the cart, the combing tooth can block stones in front of the front to prevent them from contacting and damaging the blades, thereby better protecting the blades. However, the existing device only has the function of blocking and not collecting stones. When in use, if too many stones accumulate in front of the combing tooth, the cart will be difficult to move, and the stones in front of the combing tooth need to be cleared before it can be used again.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an agricultural weeder. When it is necessary to weed the farmland, the cart 11 is first pushed to move on the farmland, and then the motor 12 drives the blade 13 to rotate. During the rotation, the taller weeds can be cut off. During the movement of the cart 11, the combing teeth 23 can block the stones in front of the cart in front of the combing teeth 23 to avoid damage to the blades. When too many stones are accumulated on the combing teeth 23, the double-headed motor 25 can be started to drive gear 2 26 to engage with gear 1 24 to drive the cross bar 22 to rotate slowly, so that the combing teeth 23 rotate slowly. During the rotation of the cross bar 22, the combing teeth 23 will be driven to rotate, and the gravel on the combing teeth can be driven to rotate, so that the gravel on the combing teeth 23 rolls along the combing teeth to the inside of the collection box 27 for collection.

[0034] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0035] Combine Figure 1-Figure 4 , an embodiment of the present application provides an agricultural weeder, comprising: a cart 11 with only a motor 12 on the top, and the output shaft passes through the cart 11; a blade 13 is arranged at the bottom of the motor 12; a collection component 2 is provided on the cart 11, and the collection component 2 comprises: a trough 21 opened on the cart 11; both ends of a cross bar 22 pass through the inner wall of the trough 21 and are fixedly connected to the trough 21; one end of a combing tooth 23 is passed through by the cross bar 22 and is fixedly connected to the cross bar 22; a gear 1 24 is fixedly sleeved on both ends of the cross bar 22; a double-headed motor 25 is arranged on the inner wall of the trough 21, and the output shafts at both ends pass through the inner wall of the trough 21; a gear 2 26 is fixedly sleeved on the output shaft of the double-headed motor 25 and meshes with the gear 1 24; a collection box 27 is arranged on the cart 11.

[0036] Specifically, the combing teeth 23 are similar to a comb structure, with many through slots at the front end for weeds to pass through. At the same time, the through slots are small and can block gravel, so that the gravel is separated from the weeds and prevent the gravel from damaging the blade.

[0037] When it is necessary to weed the farmland, first push the cart 11 to move on the farmland, and then the motor 12 drives the blade 13 to rotate. During the rotation, the tall weeds can be cut off. During the movement of the cart 11, the combing teeth 23 can block the stones in front of the cart in front of the combing teeth 23 to avoid damage to the blades. When too many stones are piled up on the combing teeth 23, the double-headed motor 25 can be started to drive gear 2 26 to engage with gear 1 24 to drive the cross bar 22 to rotate slowly, so that the combing teeth 23 rotate slowly. During the rotation of the cross bar 22, the combing teeth 23 will be driven to rotate, and the gravel on the combing teeth can be driven to rotate, so that the gravel on the combing teeth 23 rolls along the combing teeth to the inside of the collection box 27 for collection.

[0038] In some embodiments, the collection assembly 2 further includes a handle 271 disposed on the top of the collection box 27 .

[0039] When in use, the handle 271 is provided for easy grasping, and the collecting box 27 is pulled to move. The collecting box 27 can be lifted to one side to pour out the gravel inside.

[0040] In some embodiments, the collecting assembly 2 further includes: a plurality of protrusions 28 , all of which are arranged at one end of the combing teeth 23 .

[0041] When in use, the protrusion 28 is set on one end of the combing teeth 23, so that when the combing teeth 23 move and push the gravel above one end of the combing teeth 23, the protrusion 28 will prevent the gravel from rolling down, so that the gravel stays on the top of one end of the combing teeth 23.

[0042] In some embodiments, the collecting assembly 2 further includes: a baffle 29 disposed at one end of the combing teeth 23 .

[0043] During use, the setting of the baffle 29 can prevent the gravel from falling and contacting the double-headed motor 25 and causing damage to the double-headed motor 25 when the gravel rolls down from the combing teeth 23 to the inside of the collection box 27. At the same time, the inclined design of the baffle 29 can make it easier for the gravel to enter the inside of the collection box 27 when rolling.

[0044] In some embodiments, a fixing assembly 3 is provided on the cart 11 , and the fixing assembly 3 includes: a fixing groove 31 opened on the cart 11 ; a vertical plate 32 is provided at the bottom of the collection box 27 and inserted into the interior of the fixing groove 31 .

[0045] During use, when the collection box 27 is placed on the cart 11 , the vertical plate 32 is inserted into the fixing groove 31 to limit the movement of the collection box 27 .

[0046] In some embodiments, the fixing assembly 3 also includes: a card slot 33 is opened on one side of the vertical plate 32; a protrusion 34 is arranged at the bottom of the cart 11; one end of the connecting rod 35 passes through the protrusion 34; a card plate 36 is arranged at one end of the connecting rod 35; a spring 37 is arranged on one side of the protrusion 34, and the other end of the spring 37 is connected to the card plate 36.

[0047] When in use, when the vertical plate 32 passes through the fixing slot 31, the bottom end of the vertical plate 32 will contact the card plate 36, causing the card plate 36 to move to the right to compress the spring 37 until the card plate 36 is aligned with the card slot 33. Then the spring 37 rebounds and pushes the card plate 36 to move and insert into the card slot 33 to limit the position of the vertical plate 32.

[0048] In some embodiments, the fixing assembly 3 further includes: a transverse plate 38 disposed at the other end of the connecting rod 35 .

[0049] The arrangement of the transverse plate 38 can prevent the connecting rod 35 from being separated from the protruding strip 34 during use.

[0050] In some embodiments, the spring 37 is sleeved on the outside of the connecting rod 35 .

[0051] The sleeve design during use can prevent the spring 37 from bending due to the restriction of the connecting rod 35 when the spring 37 is compressed, thereby better protecting the spring 37.
