Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a soil-separating device for preventing weeds from entangled in a deep tillage plow. Background Technology

[0002] In modern agricultural tillage systems, deep tillage is a crucial step in improving soil structure, breaking up the plow pan, and enhancing the soil's water retention capacity. Traditional deep tillage equipment typically relies on tractors for traction, using a deep tillage shovel or soil divider to directly cut into the deep soil layers for loosening. With the increasing prevalence of agricultural mechanization, the demands for efficiency and quality in deep tillage operations are also rising.

[0003] However, in actual farmland operations, the surface is often covered with a large amount of weeds, crop stalks, or vines. When existing deep tillage plows are in operation, their soil-separating components come into direct contact with this surface vegetation, making them highly susceptible to entanglement. Once weeds become entangled in the soil separator, it not only significantly increases the tractor's traction resistance, leading to increased fuel consumption, but also severely affects the soil-separating depth and loosening effect, even forcing operators to frequently stop the machine to clean it, greatly reducing operational efficiency. Furthermore, the entry angle of existing soil-separating devices is mostly fixed or can only be adjusted to a limited extent through complex mechanical disassembly and assembly. This lack of flexibility in dealing with soil conditions of varying hardness and moisture makes it difficult to maintain the optimal entry posture, further hindering the improvement of deep tillage quality.

[0004] Therefore, this utility model proposes a deep tillage plow anti-weed entanglement soil-separating device to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a soil-separating device for preventing weed entanglement in deep tillage plows. This aims to improve upon existing technologies where long-stemmed weeds on the surface easily become entangled in the soil-separating components during deep tillage operations, leading to significantly increased tillage resistance, low operating efficiency, and increased fuel consumption. Furthermore, existing soil-separating devices typically employ a fixed connection structure, making adjustment of the soil entry angle extremely inconvenient or impossible. This makes it difficult to flexibly adapt to differences in soil hardness and specific tillage depth requirements across different plots, resulting in poor environmental adaptability and unstable deep tillage quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a deep tillage plow anti-weed entanglement and soil-separating device, comprising: a traction head, a device support, wheels and axle; as well as a cutting component, a rotating component and a soil separator.

[0007] The traction head is fixedly connected to the front end of the device bracket, the rotating shaft is laterally disposed at the bottom of the device bracket, and the wheels are rotatably connected to both ends of the rotating shaft. The cutting assembly is disposed inside the device bracket and near the front end, and the rotating assembly is disposed at the rear end of the device bracket. Furthermore, the cutting assembly includes a housing, a motor, a first rotating column, a fixed blade holder, and a blade; the housing is fixed to the device bracket, the motor is disposed inside the housing, the first rotating column is rotatably connected to the device bracket and is drively connected to the motor output shaft; the fixed blade holder is fixed to the outer wall of the first rotating column, and the blade is mounted on the fixed blade holder.

[0008] The rotating assembly includes a first fixed base, a hydraulic rod, a second fixed base, a fixed rod, a fixed block, and a second rotating column. The first fixed base is fixed to the device support. The bottom end of the hydraulic rod is rotatably connected to the first fixed base, and the top end of the hydraulic rod is rotatably connected to the second fixed base. The second fixed base is fixedly connected to the fixed rod, and the bottom end of the fixed rod is fixedly connected to the second rotating column. The fixed block is fixed to the device support. Both ends of the second rotating column are rotatably connected to the fixed block. The soil divider is fixed to the outer wall of the second rotating column. The extension and retraction of the hydraulic rod drives the fixed rod to swing, thereby causing the second rotating column and the soil divider to rotate and adjust their angles.

[0009] Preferably, the cutting assembly further includes a protective cover, which is fixedly connected to the inner wall of the device support. The protective cover is in an arc shape and covers the outside of the first rotating column and the blade. It is used to effectively block weed debris from flying around when the blade is rotating at high speed, protect the safety of the operator, and prevent debris from accumulating and affecting the operation of the equipment.

[0010] Preferably, the fixed blade holder has a central slot in the middle, the bottom of the blade is embedded in the central slot, and the fixed blade holder and the blade have aligned holes. The blade is fastened to the fixed blade holder by bolts passing through the holes. The embedded and bolt-locked structure significantly improves the stability of the blade when subjected to high-load cutting, and also facilitates subsequent disassembly, replacement and maintenance.

[0011] Preferably, the rotating assembly further includes a first connecting post, which passes through the connection between the first fixed seat and the bottom of the hydraulic rod. The bottom of the hydraulic rod is rotatably engaged with the first fixed seat through the first connecting post, ensuring that the hydraulic rod can swing smoothly around the axis of the first connecting post during extension and retraction to adapt to the angle changes of the linkage mechanism.

[0012] Preferably, the rotating assembly further includes a second connecting post, which passes through the connection between the second fixed seat and the top of the hydraulic rod. The top of the hydraulic rod pulls or pushes the second fixed seat through the second connecting post, thereby effectively transmitting the linear extension force of the hydraulic rod to the subsequent transmission components.

[0013] Preferably, the fixing rod moves synchronously with the second fixing seat, and the fixing rod drives the second rotating column connected to its bottom to rotate. The fixing rod, as a key arm for torque transmission, converts the displacement of the second fixing seat into torque that drives the second rotating column to rotate.

[0014] Preferably, the fixing blocks are disposed at both ends of the second rotating column, and bearing holes are provided inside the fixing blocks. The two ends of the second rotating column are inserted into the bearing holes and rotatably connected to the fixing blocks. This structure provides a stable rotation fulcrum for the second rotating column, ensuring the stability of the soil divider during angle adjustment and operation.

[0015] Preferably, the soil divider includes a plurality of arc-shaped tillage teeth, which are evenly spaced along the axial direction of the second rotating column, with the concave surface of the arc-shaped tillage teeth facing the forward direction of the device, and the cutting component is located at the front end of the soil divider in the forward direction, ensuring that the weeds on the ground have been pre-cut by the cutting component in front before the soil divider comes into contact with the soil.

[0016] This utility model has the following beneficial effects: 1. In this utility model, a cutting component driven by a motor to rotate at high speed is first set at the front end of the device. The sharp blades fixed on the rotating column solve the problem that long-stemmed weeds are easily entangled on the soil divider and other tillage parts in the existing deep tillage operation. The technical effect is to actively chop the weeds into fine chips before the soil dividing operation, eliminate the risk of entanglement from the source, ensure smooth operation and reduce the resistance of machine operation.

[0017] 2. In this utility model, by setting up a rotating assembly including a hydraulic rod, a linkage mechanism and a rotating column, the extension and retraction motion of the hydraulic rod drives the fixed rod to swing, thereby driving the rotating column on which the soil divider is installed to rotate. This solves the problem that the existing soil dividing device has a fixed angle and cannot adapt to different soil hardness or tillage depth requirements. It achieves the technical effect of being able to precisely and steplessly adjust the soil divider's entry angle according to actual agronomic requirements and soil conditions, thereby improving tillage quality and environmental adaptability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Reference Figures 1-5 This utility model provides an embodiment of a deep tillage plow anti-weed entanglement soil separating device, which aims to solve the technical problems in existing deep tillage operation technology, such as the easy entanglement of weeds in the field with the soil separating component, resulting in increased operation resistance and poor operation effect, and the fixed entry angle of the soil separating component, which cannot flexibly adapt to different soil hardness and tillage depth requirements.

[0022] The deep tillage plow anti-weed entanglement and soil-separating device mainly includes a traction head 1, a device support 2, wheels 3, and a rotating shaft 7 in its overall structure. The traction head 1 is fixedly connected to the front end of the device support 2. The traction head 1 is used to establish a stable connection with external traction power equipment such as tractors, thereby transmitting the tractor's traction force to the main body of the device. The device support 2 serves as the basic installation platform and load-bearing frame of the entire device. It is made of sturdy metal materials to withstand the resistance and vibration during tillage. The rotating shaft 7 is horizontally fixed at the bottom of the device support 2. The wheels 3 are rotatably connected to the left and right ends of the rotating shaft 7. The surface of the wheels 3 has anti-slip patterns. The wheels 3 are used to support the device support 2 and rotate around the axis of the rotating shaft 7, so that the device can move smoothly with the tractor on the farmland.

[0023] On top of the aforementioned basic mobile platform, the device support 2 also integrates a cutting component 4 for pre-treating weeds, a soil divider 6 for performing tillage operations, and a rotating component 5 for adjusting the tillage angle. The cutting component 4 is installed in the internal cavity of the device support 2 and is located on the side close to the traction head 1, so that the cutting component 4 can contact and chop the weeds on the ground before the soil divider 6 during the device's forward movement. The rotating component 5 is located in the rear area of ​​the device support 2 and is connected to the soil divider 6, changing the posture of the soil divider 6. The soil divider 6 is located at the very end of the device and is used to cut into the soil for deep loosening and soil division operations. Thus, traction movement, front-end weeding, rear-end angle adjustment, and deep loosening and soil division constitute an organically coordinated overall operation system, ensuring continuous and efficient operation in complex farmland environments.

[0024] The cutting assembly 4 mainly consists of a housing 9, a motor 8, a first rotating column 402, a fixed blade holder 403, and a blade 404. The housing 9 serves as a protective cover for the power system and is fixedly connected to the outside of the side wall of the device support 2 to isolate the internal components from field dust and debris. A high-power motor 8 is installed inside the housing 9. The motor 8 serves as a drive source, and its output shaft passes through the side wall of the device support 2 and is connected to the end of the first rotating column 402. Torque is transmitted through conventional mechanical connections such as key connections or couplings. The first rotating column 402 is laterally rotatably connected between the two inner side walls of the device support 2, and its axial direction is parallel to the rotating shaft 7, enabling it to rotate at high speed under the drive of the motor 8.

[0025] On the outer circumferential surface of the first rotating column 402, several fixed tool holders 403 are distributed at intervals along its axial direction. The fixed tool holders 403 are rigidly fixedly connected to the first rotating column 402 by welding or integral casting, and rotate synchronously with the first rotating column 402. Each fixed tool holder 403 has a central slot adapted to its shape in the middle, which provides a stable mounting reference for the blade 404. The blade 404 has a sharp cutting edge, and its bottom is embedded in the central slot of the fixed tool holder 403. The root of the blade 404 and the fixed tool holder 403 both have mutually aligned mounting through holes. The blade 404 is fastened and locked to the fixed tool holder 403 by passing through the mounting through holes with high-strength bolts 405. The connection method of bolts 405 not only ensures the stability of the blade 404 under high load cutting, but also facilitates the quick disassembly and replacement of the blade 404 after wear.

[0026] To further enhance operational safety and prevent shredded weeds from scattering and obstructing visibility or blocking other mechanisms, the cutting assembly 4 is also equipped with a protective cover 401. The protective cover 401 is a semi-circular or nearly arc-shaped plate structure, with both ends fixedly connected to the inner wall of the device support 2. The concave surface of the protective cover 401 faces downwards, covering the area above the first rotating column 402, the fixed blade holder 403, and the blade 404. The protective cover 401 can block and guide the flying debris and soil clods to the ground below when the blade 404 is cutting weeds at high speed, thereby effectively protecting the safety of the operator and keeping the device clean.

[0027] The rotating component 5 adopts a hydraulically driven linkage mechanism, with the power component being a hydraulic rod 503. The basic support structure of the rotating component 5 includes a first fixed seat 501 fixed in the middle of the device bracket 2. The bottom end of the hydraulic rod 503 is rotatably engaged with the first fixed seat 501 through a first connecting column 502, allowing the hydraulic rod 503 to swing around the axis of the first connecting column 502. The top telescopic end of the hydraulic rod 503 is rotatably connected to the second fixed seat 505 through a second connecting column 504.

[0028] The upper part of the second fixed seat 505 and the fixed rod 506 are rigidly fixedly connected to form a linkage whole. The fixed rod 506 extends to the lower part of the tail of the device support 2, and its bottom end is fixedly connected to the end of the second rotating column 508. The second rotating column 508 is the installation carrier of the soil divider 6. Its two ends are respectively rotatably supported in the fixed block 507. The fixed block 507 is firmly fixed to the left and right sides of the tail of the device support 2. The soil divider 6 is directly fixedly installed on the outer circumferential wall of the second rotating column 508. When the hydraulic rod 503 extends and retracts, it pushes the second fixed seat 505 to move, thereby driving the fixed rod 506 to generate torque around the axis of the second rotating column 508, driving the second rotating column 508 to rotate in the fixed block 507, thereby changing the soil entry angle of the soil divider 6.

[0029] Working principle: When using this weeding and soil separating device in farmland operations, the tractor's traction head 1 must first be connected to the device to prevent loosening or detachment during traction. After connection, start the tractor and drive slowly. The traction force is used through the traction head 1 to pull the main body of the device, thereby moving the device support 2. Then, the device support 2, under the force, drives the rotating shaft 7 and wheels 3 to rotate around the axis of the rotating shaft 7 to achieve the movement effect. The movement speed can be controlled within a reasonable range according to the farmland soil conditions and weed density by adjusting the tractor's gear to ensure the subsequent operation effect. The cutting component 4 can cut and crush the weeds on the path to prevent them from getting tangled in the soil separating device 6. The rotating component 5 can adjust the angle of the soil separating device 6 according to different land terrains to adapt to different lands.

[0030] During the movement of the device, the cutting component 4 at the front end will be the first to come into contact with the weeds in the field. The cutting component 4 needs to have the blade 404 installed in advance. The operator needs to place the blade 404 in the middle slot of the fixed blade holder 403, ensuring that the mounting hole of the blade 404 is fully aligned with the screw hole of the blade holder. Then, it is fixed with bolts 405. After installation, the high-speed motor 8 inside the outer casing 9 of the device is started, and then the first rotating column 402 is rotated through the output shaft. The fixed blade holder 403 is fixed to the outer wall of the first rotating column 402. Then, the first rotating column 402 drives the fixed blade holder 403 to rotate. Then, the fixed blade holder 403 drives the blade 404 to rotate rapidly. The rotating blade 404 cuts the weeds in the field with its sharp edge and further crushes them into fine fragments. At the same time, the protective cover 401 on the outside of the cutting component 4 can effectively prevent the weed fragments from flying around, which not only avoids safety hazards to the operator, but also prevents the fragments from splashing onto other transmission parts of the device and affecting its operation.

[0031] To adapt to different farming needs, the angle of the soil divider 6 needs to be adjusted by rotating component 5. The operator starts the hydraulic rod 503 by controlling the hydraulic system, and then adjusts the length of the hydraulic rod 503. The bottom of the hydraulic rod 503 is connected to the first fixed seat 501 through the first connecting column 502, while the top of the hydraulic rod 503 is connected to the second fixed seat 505 through the second connecting column 504. When the hydraulic rod 503 extends or retracts, the bottom can rotate around the axis of the first connecting column 502, and the top can pull the second fixed seat 505 through the second connecting column 504, thereby driving the fixed rod 506 fixed to the second fixed seat 505 to move synchronously. Then the fixed rod 506 drives the second rotating column 508 connected to the bottom of the fixed rod 506 to rotate, and the two ends of the second rotating column 508 are connected to the middle of the fixed block 507. When the second rotating column 508 rotates, it can drive the soil divider 6 fixed on the outer wall of the second rotating column 508 to rotate, realizing the precise adjustment of the angle of the soil divider 6.
