Abstract

This application discloses a multi-functional weeder for planting, including a frame with a steering mechanism and a drive mechanism at each end, and a weeding mechanism located in the middle of the frame. The weeding mechanism includes a tilling roller that rotates via a first support rod and a fixed sieving mechanism. A soil-throwing mechanism is located near the steering mechanism end of the frame. The tilling roller and the soil-throwing mechanism are connected via a first pulley assembly, and the soil-throwing mechanism is connected to the drive mechanism via a second pulley assembly. The drive mechanism is also connected to the tilling roller via a third pulley assembly. During operation, the drive mechanism drives the tilling roller to till the soil, and the soil-throwing mechanism directionally throws the soil mixed with weeds and stones to the sieving mechanism. The sieve vibrates to separate impurities, and the purified soil falls back into the field. This achieves integrated tillage, weeding, and soil purification, improving farming efficiency while removing weeds and soil impurities, and reducing labor intensity and costs.

Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, and specifically relates to a multi-functional weeding machine for planting. Background Technology

[0002] In agricultural production, weed control is a crucial step in ensuring crop growth, and weeders, as core agricultural equipment, directly impact planting costs and crop yields through their functional completeness and operational efficiency. Currently, many weeders on the market suffer from problems such as limited functionality, fragmented operation processes, and incomplete soil treatment, failing to meet the demands of modern agriculture for efficient and integrated operations. Specific shortcomings are as follows: Most existing weeders only have single functions of weeding or tilling. In actual planting operations, multiple machines need to be used in combination to complete the process of "tilling - weeding - soil cleaning" in steps. For example, the soil is first tilled with a tiller, and then weeds are removed manually or mechanically with a weeder. At the same time, workers also need to separate stones, root debris and other impurities from the soil. The steps are cumbersome and the equipment switching is time-consuming. Moreover, the purchase and maintenance costs of multiple machines are high, which increases the economic burden on farmers. Utility Model Content

[0003] This application provides a multi-functional weeder for planting, which integrates tillage, soil throwing, and screening mechanisms, and designs a multi-pulley assembly for coordinated transmission to achieve integrated operation of "tillage-weeding-impurity separation", thereby solving the problems of low efficiency and increased cost caused by multi-step operation in planting.

[0004] To achieve the above objectives, this application provides a multi-functional weeder for planting, wherein a steering mechanism and a drive mechanism are respectively installed at both ends of the frame, and a weeding mechanism is provided between the steering mechanism and the drive mechanism via the frame. The weeding mechanism includes a tillage roller rotatably mounted on the frame via a first support rod and a fixed sifting mechanism. A soil-throwing mechanism is provided at one end of the frame near the steering mechanism. The tillage roller is connected to the soil-throwing mechanism via a first pulley assembly, and the soil-throwing mechanism is connected to the drive mechanism via a second pulley assembly.

[0005] The soil-throwing mechanism includes a second support rod fixedly mounted on one side of the vehicle frame. A camshaft is rotatably mounted on the second support rod, and multiple connecting seats are rotatably mounted on the camshaft. A soil-throwing shovel is mounted at one end of each connecting seat near the sifting mechanism, and a first connecting rod is rotatably mounted at the other end. The first connecting rod is fixedly mounted on a second connecting rod, which is mounted on a linkage rod. A cam is rotatably mounted at the end of the linkage rod away from the second connecting rod. The cam is rotatably connected to a bearing seat via a connecting shaft, and the bearing seat is fixedly mounted on the other side of the vehicle frame.

[0006] In one embodiment, the camshaft is connected to the tillage roller via a first pulley assembly, and the connecting shaft is connected to the drive mechanism via a second pulley assembly.

[0007] In one embodiment, the screening mechanism includes a material holding frame fixedly mounted on the frame, a slotted frame extending through the bottom of the material holding frame, a screen rotatably mounted inside the slotted frame, and a compression spring positioned between the screen and the bottom of the material holding frame.

[0008] In one embodiment, the drive mechanism includes a base fixedly mounted on the vehicle frame, a drive wheel rotatably mounted on the bottom of the base, the drive wheel being connected to the output end of the transmission, the transmission being mounted on the base and its input end being connected to the engine, and the engine being mounted on the base.

[0009] In one embodiment, the output end of the transmission is also connected to the tillage roller via a third pulley assembly.

[0010] In one embodiment, a control link is provided on the vehicle frame, and the control link is connected to the transmission.

[0011] In one embodiment, the steering mechanism includes a guide wheel and a steering handle, the guide wheel being rotatably mounted on the frame and the steering handle being fixedly mounted on the frame.

[0012] Compared with the prior art, the beneficial effects of this application are: The drive mechanism sequentially drives the tillage roller to rotate and turn over the soil, and the camshaft and cam of the soil throwing mechanism move in coordination, so that the soil throwing shovel throws the soil mixed with weeds and stones to the sieving mechanism. With the help of the screen vibration to separate impurities, the tillage, weeding and soil purification are integrated into one operation, which effectively improves the efficiency of planting operations and improves the soil quality.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] See Figures 1 to 5 As shown, the multi-functional weeder for planting provided in this application has a steering mechanism and a drive mechanism installed at both ends of the frame 1, and a weeding mechanism is provided between the steering mechanism and the drive mechanism through the frame 1. The weeding mechanism includes a tillage roller 3 that is rotatably mounted on the frame 1 via a first support rod 2 and a fixed sifting mechanism 4. A soil throwing mechanism 6 is provided at one end of the frame 1 near the steering mechanism. The tillage roller 3 and the soil throwing mechanism 6 are connected through a first pulley assembly 5, and the soil throwing mechanism 6 is connected to the drive mechanism through a second pulley assembly 7.

[0018] The drive mechanism is activated, which drives the tillage roller 3 to rotate. At the same time, the tillage roller 3 drives the soil throwing mechanism 6 in a coordinated manner through the first pulley assembly 5 and the drive mechanism through the second pulley assembly 7. During its coordinated drive, the soil throwing mechanism 6 directionally throws the soil that has been tilled by the tillage roller 3 and causes it to fall into the sifting mechanism 4. The sifting mechanism 4 separates the weeds and stones mixed in the tilled soil. The separated soil falls back into the field, while the weeds and stones are collected in the sifting mechanism 4.

[0019] It should be noted that during the rotation of the tillage roller 3, the soil is tilled. At the same time, the weeds growing on it are also mixed into the soil. At this time, through the directional throwing action of the soil throwing mechanism 6, the soil mixed with weeds and stones is thrown into the sifting mechanism 4. After the sifting mechanism 4 separates the weeds and stones from the soil, the weeds are collected in the sifting mechanism 4, while the separated soil falls back into the field, realizing the integrated operation of weeding and soil treatment.

[0020] The first pulley assembly 5 and the second pulley assembly 7 have the same structure, both including a pulley body and a transmission belt. The pulley body is fixed to the corresponding shaft end, and the transmission belt connects the two pulley bodies to realize power transmission, thereby ensuring the synchronous operation between the tillage roller 3 and the soil throwing mechanism 6, and between the drive mechanism and the soil throwing mechanism 6.

[0021] The soil-throwing mechanism 6 includes a second support rod 61 fixedly mounted on one side of the frame 1. A camshaft 62 is rotatably mounted on the second support rod 61, and multiple connecting seats 64 are rotatably mounted on the camshaft 62. A soil-throwing shovel 63 is mounted on one end of each connecting seat 64 near the sifting mechanism 4, and a first connecting rod 65 is rotatably mounted on the other end. The first connecting rod 65 is fixedly mounted on a second connecting rod 66, which is mounted on a linkage rod 67. A cam 68 is rotatably mounted on the end of the linkage rod 67 away from the second connecting rod 66. The cam 68 is rotatably connected to a bearing seat 610 via a connecting shaft 69, and the bearing seat 610 is fixedly mounted on the other side of the frame 1. The camshaft 62 is connected to the tillage roller 3 via a first pulley assembly 5, and the connecting shaft 69 is connected to the drive mechanism via a second pulley assembly 7.

[0022] Under the action of the drive mechanism, the connecting shaft 69 is rotated through the second pulley assembly 7, thereby driving the cam 68 to rotate. The rotation of the cam 68 drives the second connecting rod 66 to reciprocate through the linkage rod 67. The second connecting rod 66 drives the connecting seat 64 to swing up and down around the cam shaft 62 through the first connecting rod 65. During the swinging up and down around the cam shaft 62, the connecting seat 64 drives the throwing shovel 63 to perform reciprocating lifting and deflection movements, thereby realizing the continuous throwing operation of the tilled soil.

[0023] The rotation of the tillage roller 3 drives the camshaft 62 to rotate through the first pulley assembly 5. The rotation of the camshaft 62 further drives the connecting seat 64 to reciprocate in the direction of travel, so that the dumping shovel 63 can be inserted into the soil and periodically raised and lowered with the rotation of the camshaft 62, thereby realizing continuous digging and lifting of the soil.

[0024] In summary, the drive mechanism, through the second pulley assembly 7, drives the cam 68 to achieve the periodic oscillating soil-throwing action of the throwing shovel 63 around the camshaft 62. Simultaneously, the tillage roller 3, through the first pulley assembly 5, drives the camshaft 62 to rotate, thereby driving the connecting seat 64 and the throwing shovel 63 to achieve continuous digging and lifting actions on the tilled soil. The coordinated action of the two enables the throwing shovel 63 to achieve stable periodic digging, lifting, and directional throwing operations in the tilled soil. This directional throwing method allows the tilled soil to be accurately thrown into the sifting mechanism 4, thereby further utilizing the sifting mechanism 4 to separate weeds and stones in the soil, ensuring that the entire device can achieve an integrated process of weeding, soil breaking, screening, and soil backfilling during field operations.

[0025] Optionally, the screening mechanism 4 includes a material holding frame 41 fixedly mounted on the frame 1. A slot is provided through the bottom of the material holding frame 41, and a screen 42 is rotatably mounted inside the slot. A compression spring 43 is provided between the screen 42 and the bottom of the material holding frame 41.

[0026] In this embodiment, the screen 42 vibrates reciprocally under the vibration of the drive mechanism, while the compression spring 43 provides buffering and restoring force, thereby improving the stability and continuity of the screen 42's vibration. The reciprocating vibration of the screen 42 can sieve the soil delivered by the shovel 63, removing impurities such as weeds and stones from the soil, and the soil then falls back into the field through the trough frame via the screen 42.

[0027] Optionally, the drive mechanism includes a base 9 fixedly mounted on the frame 1, a drive wheel 14 rotatably mounted on the bottom of the base 9, the drive wheel 14 being connected to the output end of the transmission 11, the transmission 11 being mounted on the base 9 and its input end being connected to the engine 10, the engine 10 being mounted on the base 9, and the output end of the transmission 11 being connected to the tillage roller 3 via a third pulley assembly.

[0028] In this embodiment, after the engine 10 starts, power is transmitted to the drive wheel 14 via the transmission 11, realizing the driving of the entire machine. At the same time, the output end of the transmission 11 transmits power to the tillage roller 3 through the third pulley assembly, so that the tillage roller 3 completes the tillage operation of the soil during rotation. By reasonably adjusting the transmission ratio of the transmission 11, the overall machine speed and the tillage depth of the tillage roller 3 can be controlled in a coordinated manner, thereby improving the quality of tillage and the efficiency of operation.

[0029] It should be noted that the third pulley assembly includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is connected to the output end of the gearbox 11, the driven pulley is connected to the rotating shaft of the tillage roller 3, and the transmission belt is sleeved between the driving pulley and the driven pulley to achieve flexible power transmission.

[0030] Optionally, a control linkage 8 is provided on the frame 1, and the control linkage 8 is connected to the transmission 11. By operating the control linkage 8, the motion transmission state of the transmission 11 can be adjusted, thereby flexibly controlling the operating speed and power distribution ratio of the drive wheel 14 and the tillage roller 3.

[0031] It should be noted that the transmission 11 and the control linkage 8 are conventional configurations of transmissions in the prior art. Their structure and principle have been widely used in the field of agricultural machinery, and will not be elaborated here.

[0032] Optionally, the steering mechanism includes a guide wheel 13 and a steering handle 12. The guide wheel 13 is rotatably mounted on the frame 1, and the steering handle 12 is fixedly mounted on the frame 1. By operating the steering handle 12, the operator can control the steering angle of the guide wheel 13, thereby flexibly adjusting the overall direction of travel of the machine to adapt to the operational needs of different terrains.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
