Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a weed cutting and cleaning device for konjac fields. Background Technology
[0002] Timely weed control is crucial for ensuring konjac yield and quality during cultivation. Currently, weed control in konjac fields mainly employs manual weeding and conventional mechanical weeding, but neither method can meet the demands for efficient, precise, and safe weed control.
[0003] While conventional mechanical weeding offers improved efficiency, it suffers from significant drawbacks. Firstly, existing machinery lacks an effective weed-gathering mechanism. When weeds are scattered across the field, the cutting mechanism can only process those it touches, leaving many uncut and resulting in incomplete weeding. This necessitates repeated operations, increasing costs and time. Secondly, the fixed positions of the cutting components in conventional machinery prevent flexible adjustments based on the height and growth stage of the konjac seedlings. This makes it highly susceptible to accidentally damaging the seedlings during weeding, causing unnecessary losses.
[0004] In view of this, we propose a weed cutting and cleaning device for konjac fields. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a device for cutting and cleaning weeds in konjac fields.
[0006] The technical solution of this utility model is:
[0007] A weed-cutting and clearing device for konjac fields includes a base. A mounting frame is welded and fixed to the front top of the base. A movable mounting plate is located below the mounting frame. Two fixed plates are symmetrically fixed to the top of the mounting plate. A retracting mechanism is rotatably mounted on the bottom of each fixed plate. Each retracting mechanism includes a hollow frame containing a chain with a sprocket. A retracting motor, coaxially fixed to the sprocket of the chain, is mounted at the top end of the hollow frame away from the fixed plate. A mounting groove is formed on the outer front wall of the mounting plate, located between the two retracting mechanisms, and a cutting component is installed inside the groove. By providing a movable mounting plate on the base, the position of the mounting plate can be flexibly adjusted according to the growth height of the weeds and the height of the konjac seedlings, avoiding damage to the konjac seedlings during operation. The design of the two gathering mechanisms allows the gathering motor to drive the sprockets on the chain to rotate before the cutting component starts working. This causes the chain to rotate, thereby gathering the weeds on both sides towards the middle and concentrating them within the working range of the cutting component. This improves the cutting efficiency and effectiveness of the cutting component and reduces missed cuts. The cutting component then precisely cuts the gathered weeds. The overall structure is compact, and the coordinated operation enhances the targeting and efficiency of weed cutting and clearing.
[0008] As a preferred technical solution, the base has two straight wheels symmetrically fixedly installed near the front and two omnidirectional wheels symmetrically fixedly installed near the rear. This facilitates timely adjustment of the travel direction in the field according to the distribution of weeds or the direction of the konjac planting rows.
[0009] As a preferred technical solution, a trolley handle is fixedly installed on the rear top side of the base. The trolley handle is U-shaped, which facilitates the operator's grip and push of the device, providing a convenient point of force for moving the device.
[0010] As a preferred technical solution, a counterweight is fixedly installed on the top of the base between the trolley handle and the mounting frame. This prevents the device from tilting forward or lifting its tail due to excessive weight at the front end during operation, ensuring the overall balance and stability of the device and making it more stable and reliable during movement and cutting operations.
[0011] As a preferred technical solution, two hydraulic cylinders are symmetrically fixedly mounted on the top of the mounting frame, and the piston rods of the two hydraulic cylinders are respectively fixedly connected to the top of the two fixed plates. The extension and retraction movement of the hydraulic cylinders can drive the mounting plates to move up and down, thereby achieving precise adjustment of the height of the retracting mechanism and the cutting component.
[0012] As a preferred technical solution, each of the fixed plates is fixedly mounted with a rotary motor at the end near the retracting mechanism, and the output shafts of the two rotary motors are respectively fixedly connected to the two hollow frames. By rotating the rotary motors in both directions, the hollow frames can be driven to rotate around the bottom of the fixed plate, thereby adjusting the angle of the retracting mechanism.
[0013] As a preferred technical solution, the cutting assembly includes a cutting motor, and a transmission shaft is coaxially fixed to the output shaft of the cutting motor. A cutting blade is fixedly mounted on the outer circumference of the transmission shaft. The cutting motor drives the transmission shaft to rotate, thereby causing the cutting blade to rotate at high speed, which can quickly and efficiently cut the weeds gathered together by the gathering mechanism.
[0014] As a preferred technical solution, the cutting motor is fixed to the top of the mounting plate, and the cutting blade is located within the mounting groove. This provides a stable mounting area for the cutting motor and the cutting blade.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention, through the design of two gathering mechanisms, utilizes a gathering motor to drive the sprockets on the chain to rotate before the cutting component begins operation. This causes the chain to rotate, thereby gathering the weeds on both sides towards the center, concentrating the weeds within the working range of the cutting component. This improves the cutting efficiency and effectiveness of the cutting component, reduces missed cuts, and allows the cutting component to precisely cut the gathered weeds. The overall structure is compact, and the coordinated operation enhances the targeting and efficiency of weed cutting and clearing. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model provides a technical solution:
[0025] A weed-cutting and clearing device for konjac fields includes a base 1. A mounting frame 2 is welded and fixed to the front top of the base 1. A movable mounting plate 4 is provided below the mounting frame 2. Two fixed plates 40 are symmetrically fixed to the top of the mounting plate 4. A gathering mechanism 6 is rotatably mounted at the bottom of each fixed plate 40. The gathering mechanism 6 includes a hollow frame 60, in which a chain 61 with a sprocket is installed. A gathering motor 62 is installed at the top of the hollow frame 60 away from the fixed plate 40, coaxially fixed with the sprocket in the chain 61. A mounting groove 41 is formed on the outer front wall of the mounting plate 4, located between the two gathering mechanisms 6, and a cutting component 7 is installed inside it. By setting the movable mounting plate 4 on the base 1, the position of the mounting plate 4 can be flexibly adjusted according to the growth height of the weeds and the height of the konjac seedlings, avoiding damage to the konjac seedlings during operation. The design of the two gathering mechanisms 6 allows the gathering motor 62 to drive the sprocket on the chain to rotate before the cutting component 7 starts working. This causes the chain to run, thereby gathering the weeds on both sides towards the middle and concentrating them within the working range of the cutting component 7. This improves the cutting efficiency and effectiveness of the cutting component 7, reduces missed cuts, and allows the cutting component 7 to precisely cut the gathered weeds. The overall structure is compact, and the coordinated work enhances the targeting and efficiency of weed cutting and cleaning.
[0026] In a preferred embodiment, the base 1 has two straight wheels 13 symmetrically fixedly installed near the front and two omnidirectional wheels 12 symmetrically fixedly installed near the rear. This facilitates timely adjustment of the travel direction in the field according to the distribution of weeds or the direction of the konjac planting rows.
[0027] In a preferred embodiment, a trolley handle 11 is fixedly installed on the top rear side of the base 1. The trolley handle 11 is U-shaped, which facilitates the operator's grip and push of the device, providing a convenient point of force for moving the device.
[0028] In a preferred embodiment, a counterweight 10 is fixedly installed on the top of the base 1 between the trolley handle 11 and the mounting bracket 2. This prevents the device from tilting forward or lifting its tail due to excessive weight at the front end during operation, ensuring the overall balance and stability of the device and making it more stable and reliable during movement and cutting operations.
[0029] In a preferred embodiment, two hydraulic cylinders 3 are symmetrically fixedly mounted on the top of the mounting bracket 2, and the piston rods of the two hydraulic cylinders 3 are respectively fixedly connected to the top of the two fixed plates 40. The extension and retraction movement of the hydraulic cylinders 3 can drive the mounting plates 4 to move up and down, thereby achieving precise adjustment of the height of the retracting mechanism 6 and the cutting assembly 7.
[0030] In a preferred embodiment, each fixed plate 40 is fixedly mounted with a rotary motor 5 near the end of the retracting mechanism 6, and the output shafts of the two rotary motors 5 are respectively fixedly connected to the two hollow frames 60. By rotating the rotary motors 5 in both directions, the hollow frames 60 can be driven to rotate around the bottom of the fixed plate 40, thereby adjusting the angle of the retracting mechanism 6.
[0031] In a preferred embodiment, the cutting assembly 7 includes a cutting motor 70, with a transmission shaft 71 coaxially fixed to the output shaft of the cutting motor 70, and a cutting blade 72 fixedly mounted on the outer circumference of the transmission shaft 71. The cutting motor 70 drives the transmission shaft 71 to rotate, thereby causing the cutting blade 72 to rotate at high speed, which can quickly and efficiently cut the weeds gathered together by the gathering mechanism 6.
[0032] In a preferred embodiment, the cutting motor 70 is fixed to the top of the mounting plate 4, and the cutting blade 72 is located within the mounting groove 41. This provides a stable mounting area for the cutting motor 70 and the cutting blade 72.
[0033] When using the konjac field weed cutting and clearing device of this utility model:
[0034] When using this konjac field weed cutting and clearing device, the device should first be pre-adjusted according to the row spacing, weed distribution range, and growth height of the konjac seedlings. By controlling the extension and retraction of the two hydraulic cylinders 3 on the top of the mounting frame 2, the mounting plate 4 is moved up and down, thereby adjusting the gathering mechanism 6 and the cutting component 7 to a suitable height to avoid damaging the konjac seedlings during operation; at the same time, the rotary motor 5 on the fixed plate 40 is started, which drives the hollow frame 60 to rotate, adjusting the opening angle of the two gathering mechanisms 6 to ensure accurate coverage of the weed growth area.
[0035] After adjustment, the operator holds the U-shaped trolley handle 11 to push the device. The straight wheel 13 on the front side of the bottom of the base 1 provides straight guidance, while the omnidirectional wheel 12 on the rear side assists in flexible steering. The counterweight 10 ensures that the device remains balanced and stable during movement. During the movement, the gathering motor 62 of the gathering mechanism 6 is started first. The motor drives the chain 61 with sprockets inside the hollow frame 60 to rotate. The chain gathers the weeds on both sides towards the middle, concentrating them in the area between the two gathering mechanisms 6.
[0036] When the gathered weeds enter the mounting groove 41 on the front side of the mounting plate 4, the cutting motor 70 of the cutting assembly 7 is started. The motor drives the transmission shaft 71 to rotate, which in turn causes the cutting blade 72 located in the mounting groove 41 to rotate at high speed, so as to quickly and efficiently cut the gathered weeds.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
