[0002] Special weeding devices for farmland are mechanical equipment used for efficient weeding in agricultural production. Common types include mechanical weeders, laser weeders, and ultrasonic weeding devices. Among them, mechanical weeders are the most common. They cut or remove weeds by rotating blades or rollers. This device is usually connected to a tractor or other agricultural vehicle to weed a large area through traction. The advantage of mechanical weeders is that they can efficiently and quickly deal with weeds in large fields, while avoiding the use of chemical herbicides, thereby reducing pollution to the soil and the environment.

[0003] If the weeds between the ridges are not cleared, they will compete with crops for water, nutrients and sunlight. Especially during the critical period of crop growth, the presence of weeds will affect the normal growth of crops and lead to a decrease in yield. Some weeds are habitats for pests and diseases. They provide shelter for pests. Removing weeds can reduce the breeding of pests and thus protect crops from pests and diseases.

[0034] A transmission assembly 5 is rotatably mounted on the left end of the left baffle 1. The transmission assembly 5 can drive the entire device at the same time, thereby improving the utilization rate of the power source and reducing the waste of the power source.

[0035] The two baffles 1 are both rotatably mounted with a push-off assembly 6 on the upper front sides of the ends close to each other. The push-off assembly 6 can be used to remove weeds without damaging the planted crops, thereby improving the subsequent weed cleaning efficiency.

[0036] The rear ends of the two baffles 1 are fixedly mounted with a material storage assembly 7. The material storage assembly 7 cooperates with the pushing assembly 6 to achieve uniform collection of weeds, so as to facilitate subsequent uniform treatment of the crushed weeds.

[0038] For details, see Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 The mowing assembly 4 includes three transmission rods 41, and the left and right ends of the three transmission rods 41 are respectively rotatably connected to the front lower part of the end where the left baffle plate 1 and the leftmost material stripping plate 62 are close to each other, the front lower part of the end where the two material stripping plates 62 in the middle are close to each other, and the front lower part where the right baffle plate 1 and the rightmost material stripping plate 62 are close to each other are fixedly connected to the mowing roller 42 on the outer surfaces of the three transmission rods 41. The front lower part where the left baffle plate 1 and the leftmost material stripping plate 62 are close to each other, the front lower part where the two material stripping plates 62 in the middle are close to each other, and the front lower part where the right baffle plate 1 and the rightmost material stripping plate 62 are close to each other are fixedly connected to the triangular plates 43. The three triangular plates 43 are respectively located at the rear sides of the three mowing rollers 42, and the left side walls and the right side walls of the inner surfaces of the three triangular plates 43 are rotatably connected to the driving roller 1 44 together. The upper diagonal positions of the rear sides of the ends where the material plates 62 are close to each other, the upper diagonal positions of the rear sides of the ends where the two material stripping plates 62 in the middle are close to each other, and the upper diagonal positions of the rear sides of the ends where the right baffle plate 1 and the rightmost material stripping plate 62 are close to each other are all connected to the driving roller 2 45 for rotation together, and the outer surfaces of the driving roller 1 44 and the driving roller 2 45 on the same side are fixedly connected to the conveyor belt 46, and a plurality of material threading grooves 47 are arranged in an array on the outer surfaces of the three conveyor belts 46, and the middle part of the front side of the end where the left baffle plate 1 and the leftmost material stripping plate 62 are close to each other, the middle part of the front side of the ends where the two material stripping plates 62 in the middle are close to each other, and the middle part of the front side of the end where the right baffle plate 1 and the rightmost material stripping plate 62 are close to each other are all connected to the driving roller 45 for rotation together, and the outer surfaces of the three transmission rods 41 on the left side and the left end of the material stripping roller 48 on the same side are fixedly connected to the pulley 1 49, and the outer surfaces of the two pulleys 1 49 on the same side are wrapped with the belt 1 40.

[0039] Furthermore, placement holes 431 are opened on the rear sides of the upper ends of the three triangular plates 43, and a connecting rod 451 is fixedly connected to the inner surfaces of the three driving rollers 45. The left and right ends of the connecting rod 451 are rotatably connected to the left baffle plate 1 and the right baffle plate 1 respectively, and a plurality of push plates 481 are fixedly connected to the outer surfaces of the three material-discharging rollers 48 in a circular array.

[0040] Furthermore, the transmission assembly 5 includes a transmission column 1 51 fixedly connected to the left end of the driving rod 65, a transmission column 2 53 fixedly connected to the left end of the pulley 1 49 fixedly connected to the material-discharging roller 48, and a transmission column 3 54 fixedly connected to the left end of the connecting rod 451. The transmission column 1 51, the transmission column 2 53 and the transmission column 3 54 all penetrate the right end of the baffle 1 on the left side and extend to the outside. The outer surfaces of the transmission column 1 51, the transmission column 2 53 and the transmission column 3 54 are all fixedly connected to the pulley 2 55, and the outer surfaces of the three pulleys 2 55 are commonly wrapped with a belt 2 56. The pulley 2 55 located in the middle is fixedly connected to the output end of the motor 3 through a coupling.

[0041] Furthermore, the outer surface of the driving rod 65 and the outer surfaces of the three transmission rods 41 on the left and right sides thereof are fixedly connected with pulley three 66, and the outer surfaces of the two pulley three 66 on the same side are commonly wound with belt three 67.

[0042] It can be known from the above that the pulley 2 55 located in the middle is fixedly connected to the output end of the motor 3 through the coupling. Therefore, when the motor 3 is started, the output end of the motor 3 can drive the pulley 2 55 fixedly connected thereto to rotate through the coupling, and the outer surfaces of the three pulleys 2 55 are commonly wound with a belt 2 56. Therefore, when one of the pulleys 2 55 rotates, under the transmission action of the belt 2 56, the three pulleys 2 55 are caused to rotate at the same time. The three pulleys 2 55 are respectively fixedly connected to the transmission column 1 51, the transmission column 2 53 and the transmission column 3 54, so they can drive the transmission column 1 51, the transmission column 2 53 and the transmission column 3 The three transmission rods 41 are rotated at the same time, and the transmission column 51 is fixedly connected to the driving rod 65, and the outer surface of the driving rod 65 and the left side and the right side of the outer surface of the three transmission rods 41 are fixedly connected with pulleys 3 66, and the outer surfaces of the two pulleys 3 66 on the same side are commonly wound with belts 3 67. Therefore, when the driving rod 65 rotates, the three transmission rods 41 can be driven to rotate at the same time under the transmission action of the pulleys 3 66 and the belts 3 67 on the same side, and the outer surfaces of the three transmission rods 41 are fixedly connected with mowing rollers 42. Therefore, when the device moves forward as a whole, the weeds will be broken by the mowing rollers 42 in a rotating state;

[0043] At the same time, since one of the pulleys 2 55 is fixedly connected to the transmission column 2 53, and the transmission column 2 53 is fixedly connected to the left end of the pulley 1 49 fixedly connected to the feeding roller 48, the feeding roller 48 and the pulley 1 49 can be driven to rotate at the same time, and the left sides of the outer surfaces of the three transmission rods 41 are fixedly connected to the left ends of the feeding roller 48 on the same side with pulleys 1 49, and the outer surfaces of the two pulleys 1 49 on the same side are commonly wound with belt 1 40, thereby improving the transmission efficiency between the transmission rod 41 and the feeding roller 48 and the stability during transmission. When the feeding roller 48 rotates, since the device moves forward as a whole, the crushed weeds can be shoveled up through the front side of the triangular plate 43. When the crushed weeds are shoveled up, under the rotation of the feeding roller 48, a plurality of push plates 481 fixedly connected to its surface can be driven to rotate, and one side of the conveyor belt 46 is located at the triangular plate 43. The placement hole 431 is opened on the upper part of the plate 43, so several push plates 481 can push the weeds to the upper end of the conveyor belt 46, and the conveyor belt 46 is fixedly connected to the surface of the driving roller 1 44 and the driving roller 2 45, and the connecting rod 451 fixedly connected to the inner surface of the driving roller 2 45 is fixedly connected to the transmission column 3 54, and the pulley 2 55 fixedly connected to the transmission column 3 54 rotates with the transmission of the belt 2 56, thereby driving the conveyor belt 46 to transmit, and then the weeds enter the threading groove 47 opened on the surface of the conveyor belt 46, so as to achieve the effect of cleaning and transmitting the weeds, and the inner surfaces of the three driving rollers 2 45 are fixedly connected to the connecting rod 451, so when the connecting rod 451 rotates, the three driving rollers 2 45 can be driven to rotate at the same time, so as to achieve the effect of the three conveyor belts 46 transmitting the crushed weeds on the same side at the same time, thereby improving the transportation efficiency of the weeds.

[0044] Embodiment 3: This embodiment is based on Embodiment 2 and is for achieving the purpose of uniformly collecting weeds in transportation.

[0045] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.10 The material storage assembly 7 includes a feed box 71, the rear ends of the four material shifting plates 62 are fixedly connected to the rear ends of the two baffle plates 1, a handle 72 is fixedly connected to the rear edge of the upper end of the feed box 71, and three material storage boxes 73 are fixedly connected to the lower end of the handle 72 in a linear array, and the rear edges of the inner surfaces of the three material storage boxes 73 are rotatably connected to material taking doors 74, and the upper front ends of the three material storage boxes 73 are provided with feed ports 76 that communicate with the inner cavity of the material storage boxes 73, and the left side walls and right side walls of the inner surfaces of the three feed ports 76 are fixedly connected to guide plates 75.

[0046] Furthermore, the three guide plates 75 are all arranged in an inclined shape, and the front sides of the upper ends of the three guide plates 75 are in contact with the lower rear sides of the outer surfaces of the three conveyor belts 46.

[0047] Furthermore, the front diagonal portion of the ends of the two baffles 1 that are away from each other, the rear diagonal portion of the left end of the leftmost storage box 73, and the rear diagonal portion of the right end of the rightmost storage box 73 are all rotatably connected with rollers 8.

[0048] It can be seen from the above that the front diagonal portions of the ends of the two baffles 1 that are away from each other, the rear diagonal portions of the left end of the leftmost storage box 73, and the rear diagonal portions of the right end of the rightmost storage box 73 are all rotatably connected with rollers 8. Therefore, when the device is in use, it is only necessary to hold the handle 72 and then push it forward, and the entire device can be driven to move under the action of the rollers 8 on both sides, thereby satisfying the above-mentioned effect of moving the entire device;

[0049] When the crushed weeds are transported to the rear end by the conveyor belt 46, it can be seen from the above that the three guide plates 75 are all arranged in an inclined shape, and the front sides of the upper ends of the three guide plates 75 are in contact with the lower rear sides of the outer surfaces of the three conveyor belts 46. Therefore, the weeds will fall into the feed port 76 from the guide plates 75 on the same side, and then fall into the corresponding storage box 73 from the feed port 76 for storage. When the collected weeds need to be taken out later, it is only necessary to rotate and open the corresponding material taking door 74 to take out the weeds stored in the storage box 73.

[0050] Embodiment 4: Based on Embodiment 3, this embodiment aims to achieve the purpose of avoiding cutting surrounding crops when crushing weeds between ridges.

[0051] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 The pushing assembly 6 includes a driving rod 65 that is rotatably connected to the front edge of the upper end of two baffles 1 that are close to each other. The outer surface of the driving rod 65 is rotatably connected to two symmetrically distributed hollow plates 64. The lower ends of the two hollow plates 64 are fixedly connected to connecting plates 61. The left and right ends of the two connecting plates 61 are fixedly connected to the material pushing plates 62. The lower parts of the two material pushing plates 62 that are close to each other are fixedly connected to a U-shaped rod 63.

[0052] Furthermore, the outer surfaces of the two mutually adjacent material-push plates 62 are both arranged in an eight-shaped configuration, and the outer surfaces of the three transmission rods 41 respectively penetrate the material-push plates 62 on the same side and are rotatably connected to the U-shaped rods 63 on the same side.

[0053] During the use of this solution, in order to avoid cutting crops when dealing with weeds between ridges, this solution is configured by setting the outer front surfaces of the two mutually adjacent material-digging plates 62 in an eight-shaped shape. Therefore, when the material-digging plates 62 move forward, the crops in the ridges will be gathered to the inner sides of the two mutually adjacent material-digging plates 62, thereby avoiding cutting crops when crushing the weeds, thereby improving the weed cleaning efficiency;

[0054] Furthermore, the outer surfaces of the three transmission rods 41 are respectively passed through the same-side material-diverting plate 62 and are rotatably connected to the same-side U-shaped rod 63, thereby achieving the limiting effect on the three transmission rods 41, thereby improving the stability during subsequent transmission;

[0055] Since the rear ends of the four material-pickup plates 62 and the rear ends of the two baffles 1 are fixedly connected to the front end of the feed box 71, the four material-pickup plates 62 are limited and fixed. When the four material-pickup plates 62 are limited and fixed, the hollow plate 64 fixedly connected at the upper end thereof will not rotate along with the rotation of the driving rod 65, thereby realizing the transmission step in the above embodiment.

[0056] It should be noted that the specific installation method of the motor 3, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0057] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
