Description

Technical Field

[0001] This application relates to the technical field of agricultural planting for digging trenches, and particularly to a trench-digging device for vegetable planting. Background Art

[0002] During the process of vegetable planting, trench digging and ridging not only facilitate drainage, reducing waterlogging damage to vegetable roots caused by accumulated water, but also heat up and oxygenate the soil, increasing water permeability and soil depth, thereby improving soil fertility, enhancing soil structure, promoting crop growth, increasing yields. Additionally, it has advantages such as reducing labor costs, improving fertilizer utilization efficiency, and reducing diseases. Therefore, trench digging and ridging are very important steps in vegetable planting.

[0003] Different vegetables have different planting patterns and different requirements for planting spacing. Therefore, different vegetables have different requirements for trench depth and width during planting. Although mechanized trench digging can be carried out in the prior art, liberating human hands, the trench width and depth of most traditional trench-digging devices are single. When planting different vegetables, it is necessary to replace trench-digging devices or trench-digging tools of different specifications for trench digging. This not only makes the operation very troublesome but also reduces the working efficiency of trench digging. Moreover, if the soil viscosity is relatively high during trench digging, a large amount of soil will accumulate on the trench-digging tool and cannot be removed in time, greatly increasing the load on the trench-digging tool, thereby reducing the speed of soil turning and trench digging and significantly lowering the trench-digging efficiency.

[0004] Therefore, we propose a trench-digging device for vegetable planting to solve the above problems. Summary of the Invention

[0011] Furthermore, the conversion member also includes a mounting frame, a servo motor, a limit screw rod, a limit slider and a limit barrier rod; The mounting bracket is fixedly connected to the protective cover, the servo motor is fixedly connected to the mounting bracket, one end of the limit screw is fixedly connected to the output shaft of the servo motor, the other end of the limit screw is rotatably connected to the top of the mounting bracket, the limit slider is threadedly connected to the limit screw, the mounting bracket and the protective cover are both provided with a limit slide groove, the limit slide slider is slidably connected to the limit slide groove, and the limit guard rod is fixedly connected to the limit slider.

[0012] Further, a detection member is also provided on the groove width adjusting member. The detection member includes a soil resistance sensor and a vibrator. The soil resistance sensor is arranged at the end of the blade. There are multiple vibrators which are respectively installed inside the outer installation cylinder and the inner installation cylinder. The soil resistance sensor is electrically connected to the vibrator through a controller.

[0013] Further, the groove depth adjusting member includes a mounting shell, a lifting slider, a lifting adjusting motor, a lifting adjusting lead screw and a limiting rod.

[0015] Further, there are two soil pushing plates which are symmetrically arranged with respect to the two gears. The two soil pushing plates are inclined outward from bottom to top.

[0016] Compared with the prior art, the advantages of this application are as follows: (1) By arranging a groove width adjusting member on the groove depth adjusting member, when adjusting the trench digging depth, the lifting adjusting motor works to drive the lifting adjusting lead screw to rotate. Under the limiting action of the limiting rod, the lifting slider is driven to move up and down inside the mounting shell, so as to drive the groove width adjusting member and the trench opening member to perform lifting adjustment, thereby adjusting the trench digging depth. When adjusting the trench digging width, the width adjusting motor rotates clockwise. The width adjusting motor works to drive the bidirectional reciprocating lead screw to rotate. Under the limiting action of the limiting railing, the outer installation cylinder and the inner installation cylinder are driven to move away from or close to each other through the moving frame, so as to drive the blades on the outer installation cylinder and the inner installation cylinder to move away from or close to each other, changing the overlapping area of the blades, and thus changing the trench digging width by changing the working width of the blades. This enables a set of equipment to meet the planting requirements of various different types of vegetables, eliminating the need to frequently replace different models of blades, making vegetable planting more convenient and efficient.

[0017] (2) By setting a detection part on the trench width adjustment part, the greater the soil viscosity, the greater the resistance of the blade when turning the soil. The soil with high viscosity will adhere to and accumulate on the blade, which will not only greatly weaken the turning ability of the blade, but also increase the gravity of the blade, thereby greatly reducing the turning efficiency. Therefore, when the soil resistance sensor detects that the soil resistance increases, the soil resistance sensor transmits the detected signal to the controller, and the controller controls the vibration of the vibrator to vibrate, thereby causing the blade to vibrate, preventing clay from accumulating on the blade, reducing the load on the blade, and improving the trenching efficiency.

[0018] (3) By setting the conversion part, when adjusting the trenching width, first start the servo motor to drive the limit screw to rotate. Under the limiting action of the limit slider and the limit slide groove, the limit bar moves downward between the blades. Then, when the width adjustment motor rotates clockwise, the bidirectional reciprocating screw drives the ratchet to rotate. The rotation of the ratchet will squeeze the movable teeth to shrink into the movable groove. At this time, the bidirectional reciprocating screw rotates between the outer mounting cylinder and the inner mounting cylinder. Since the limit bar is located between the blades, it can limit the outer mounting cylinder and the inner mounting cylinder, so it will not drive the outer mounting cylinder and the inner mounting cylinder to rotate together. When the width adjustment motor rotates clockwise, the bidirectional reciprocating screw drives the ratchet to rotate. The rotation of the ratchet will squeeze the movable teeth to shrink into the movable groove. At this time, the bidirectional reciprocating screw rotates between the outer mounting cylinder and the inner mounting cylinder. Since the limit bar is located between the blades, it can limit the outer mounting cylinder and the inner mounting cylinder, so it will not drive the outer mounting cylinder and the inner mounting cylinder to rotate together. When rotating counterclockwise, the rotation of the ratchet will drive the movable teeth to rotate together, thereby driving the outer mounting cylinder, the inner mounting cylinder and the blades thereon to rotate synchronously. Therefore, the adjustment of the trenching width and the soil turning work can be achieved through only one motor, and when turning the soil, the width adjustment motor drives the blades on the outer mounting cylinder and the inner mounting cylinder to rotate through the ratchet and the movable teeth, which can avoid the torque generated when turning the soil from acting on the connection between the two-way reciprocating screw and the movable frame, thereby preventing the threaded teeth at the connection between the two-way reciprocating screw and the movable frame from being deformed, thereby achieving a protective effect on the two-way reciprocating screw and the movable frame.

[0019] (4) By setting up the trenching parts, the trenching motor drives the two gears to rotate in opposite directions, thereby driving the two bulldozers to expand or contract, and adjusting the maximum distance of the bulldozer opening, so as to achieve the adjustment of the trenching width.

[0020] (5) By staggering the blades on the outer mounting tube and the inner mounting tube, the staggered blades can be moved to change the overall working width of the blades, thereby achieving adjustment of the trenching width.

[0021] (6) By arranging a dredging and squeezing block with a sharp angle on one side of the mounting seat on the inner mounting cylinder close to the clearance groove, when the blade is moved and adjusted, the dredging and squeezing block with a sharp angle can dredge the stones and soil stuck in the clearance groove, thereby ensuring that the blade can smoothly achieve width adjustment.

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment 1

[0025] The present invention provides a trench digging device for vegetable planting. Please refer to Figure 1-9, including a connecting frame 1. One end of the connecting frame 1 is provided with a trench depth adjusting member 2. By adjusting the height of the blade 408, the depth of the trench can be adjusted, so that the depth of the trench can be adjusted according to different types of vegetables. One end of the trench depth adjusting member 2 is provided with a connecting plate 3. One end of the connecting plate 3 away from the trench depth adjusting member 2 is provided with a trench width adjusting member 4. By adjusting the distance between the blades 408, the width of the trench can be adjusted, so that the width of the trench can be adjusted according to different types of vegetables. Thus, a set of equipment can meet the planting requirements of a variety of different types of vegetables, without the need to frequently replace different models of blades 408, making vegetable planting more convenient and efficient. The trench width adjusting member 4 is provided with a trench opening member 5, which can adjust the distance between the outermost ends of the earth-pushing plate 504 by adjusting the opening angle of the earth-pushing plate 504, so as to adjust the width of the trench opening.

[0026] The trench width adjusting member 4 includes a protective cover 401, a width adjusting motor 402, a bidirectional reciprocating lead screw 403, an outer mounting cylinder 404, an inner mounting cylinder 405, a moving frame 406, a mounting seat 407 and a blade 408. The protective cover 401 is fixedly connected to one end of the connecting plate 3. The width adjusting motor 402 is fixedly installed on the protective cover 401. The bidirectional reciprocating lead screw 403 is rotatably connected to the protective cover 401. One end of the bidirectional reciprocating lead screw 403 penetrates through the protective cover 401 and extends to the outside of the protective cover 401 and is fixedly connected to the output shaft of the width adjusting motor 402. Both the outer mounting cylinder 404 and the inner mounting cylinder 405 are slidably sleeved on the outside of the bidirectional reciprocating lead screw 403. The outer mounting cylinder 404 is slidably sleeved on the outside of the inner mounting cylinder 405. There are two moving frames 406. The two moving frames 406 are respectively fixedly connected to the inside of the outer mounting cylinder 404 and the inner mounting cylinder 405. The two moving frames 406 are respectively threadedly connected to both ends of the bidirectional reciprocating lead screw 403. There are several mounting seats 407 evenly fixedly connected to the outside of the outer mounting cylinder 404 and the inner mounting cylinder 405. The blade 408 is detachably connected to the mounting seat 407. The blades 408 on the outer mounting cylinder 404 and the inner mounting cylinder 405 are staggered. A relief groove 409 is opened at a position on the outer mounting cylinder 404 corresponding to the mounting seat 407 on the inner mounting cylinder 405. The relief groove 409 is slidably connected to the mounting seat 407 on the inner mounting cylinder 405. The staggered blades 408 can change the overall working width of the blades 408 by moving, so as to realize the adjustment of the trench width. A dredging extrusion block 410 is fixedly connected to one side of the mounting seat 407 on the inner mounting cylinder 405 close to the relief groove 409. The side of the dredging extrusion block 410 facing the inside of the relief groove 409 is set to be a sharp angle. When the blade 408 is adjusted by moving, the sharp angle on the dredging extrusion block 410 can dredge the stones and soil blocks stuck in the relief groove 409, ensuring that the blade 408 can smoothly realize the width adjustment.

[0027] When adjusting the trenching width, the width adjustment motor 402 rotates clockwise (with Figure 1 the perspective as a reference), and the width adjustment motor 402 drives the bi-directional reciprocating lead screw 403 to rotate. Under the limiting action of the conversion member 6, the outer mounting cylinder 404 and the inner mounting cylinder 405 are driven to move away from or close to each other by the moving frame 406, so as to drive the blades 408 on the outer mounting cylinder 404 and the inner mounting cylinder 405 to move away from or close to each other, changing the overlapping area of the blades 408, and thus changing the trenching width by changing the working width of the blades 408.

[0028] Conversion members 6 are provided at both ends of the bi-directional reciprocating lead screw 403, which can convert the state of the blade 408. The conversion member 6 includes a ratchet wheel 601, a conversion box 602, movable teeth 603, a slider 604, a chute 605 and a step surface 606; a through hole is opened in the middle of the ratchet wheel 601, the slider 604 is fixedly connected to the hole wall of the through hole, the chute 605 is opened at the end of the bi-directional reciprocating lead screw 403, the slider 604 is slidably connected with the chute 605, the conversion boxes 602 at both ends of the bi-directional reciprocating lead screw 403 are respectively fixedly connected to the outer walls of the outer mounting cylinder 404 and the inner mounting cylinder 405, several movable grooves are opened inside the conversion box 602, the movable teeth 603 are slidably connected with the movable grooves, the movable teeth 603 and the movable grooves are connected by elastic elements, and the step surfaces 606 are opened at both ends of the ratchet wheel 601.

[0029] The conversion member 6 further includes a mounting frame 607, a servo motor 608, a limiting lead screw 609, a limiting slider 610 and a limiting railing 611; the mounting frame 607 is fixedly connected to the protective cover 401, the servo motor 608 is fixedly connected to the mounting frame 607, one end of the limiting lead screw 609 is fixedly connected to the output shaft of the servo motor 608, the other end of the limiting lead screw 609 is rotatably connected to the top of the mounting frame 607, the limiting slider 610 is threadedly connected with the limiting lead screw 609, limiting chutes are opened on both the mounting frame 607 and the protective cover 401, the limiting slider 610 is slidably connected with the limiting chutes, and the limiting railing 611 is fixedly connected to the limiting slider 610.

[0030] When adjusting the trenching width, first start the servo motor 608 to drive the limiting lead screw 609 to rotate. Under the limiting action of the limiting slider 610 and the limiting chute, the limiting railing 611 moves downward between the blades 408. Then, the width adjustment motor 402 rotates clockwise (with Figure 1From a reference perspective, the bidirectional lead screw 403 drives the ratchet wheel 601 to rotate. When the ratchet wheel 601 rotates, it squeezes the movable teeth 603 to contract inside the movable groove. At this time, the bidirectional lead screw 403 rotates between the outer mounting cylinder 404 and the inner mounting cylinder 405. Since the limiting railing 611 is located between the blades 408 and can limit the outer mounting cylinder 404 and the inner mounting cylinder 405, it will not drive the outer mounting cylinder 404 and the inner mounting cylinder 405 to rotate together. After the trench width adjustment is completed, the servo motor 608 reverses to drive the limiting railing 611 to rise away from the blade 408. Then, the width adjustment motor 402 rotates counterclockwise. The rotation of the ratchet wheel 601 will drive the movable teeth 603 to rotate together, so as to drive the outer mounting cylinder 404, the inner mounting cylinder 405 and the blades 408 thereon to rotate synchronously. Therefore, only one motor can be used to realize the adjustment of the trench width and the soil turning work. And when turning the soil, the width adjustment motor 402 drives the blades 408 on the outer mounting cylinder 404 and the inner mounting cylinder 405 to rotate through the ratchet wheel 601 and the movable teeth 603, which can avoid the torque generated during soil turning acting on the connection between the bidirectional lead screw 403 and the moving frame 406, thereby preventing the thread teeth at the connection between the bidirectional lead screw 403 and the moving frame 406 from deforming, and realizing the protection of the bidirectional lead screw 403 and the moving frame 406.

[0031] A detection member 7 is further provided on the trench width adjustment member 4, which can detect the viscosity of the soil according to the magnitude of the soil resistance. When it detects an increase in the soil resistance, it prevents the clay from accumulating through vibration, ensuring the efficient progress of the trench digging work. The detection member 7 includes a soil resistance sensor 701 and a vibrator 702; the soil resistance sensor 701 is arranged at the end of the blade 408, and there are multiple vibrators 702 which are respectively installed inside the outer mounting cylinder 404 and the inner mounting cylinder 405. The soil resistance sensor 701 is electrically connected to the vibrator 702 through a controller.

[0032] The greater the soil viscosity, the greater the resistance of the blade 408 during soil turning. And the soil with high viscosity will adhere and accumulate on the blade 408. This will not only greatly weaken the soil turning ability of the blade 408, but also increase the gravity of the blade 408, thus greatly reducing the soil turning efficiency. Therefore, when the soil resistance sensor 701 detects an increase in the soil resistance, the soil resistance sensor 701 transmits the detected signal to the controller, and the controller controls the vibrator 702 to vibrate, so that the blade 408 vibrates, preventing the clay from accumulating on the blade 408, reducing the load of the blade 408, and improving the trench digging efficiency.

[0033] The trench depth adjusting member 2 includes an installation shell 201, a lifting slider 202, a lifting adjusting motor 203, a lifting adjusting lead screw 204, and a limiting rod 205; the installation shell 201 is fixedly connected to the connecting frame 1, the lifting slider 202 is slidably connected to the installation shell 201, the lifting slider 202 is fixedly connected to the other end of the connecting plate 3, the lifting adjusting motor 203 is fixedly connected to the inner bottom wall of the installation shell 201, one end of the lifting adjusting lead screw 204 is fixedly connected to the output end of the lifting adjusting motor 203, the other end of the lifting adjusting lead screw 204 is rotatably connected to the inner top wall of the installation shell 201, the limiting rod 205 is fixedly connected inside the installation shell 201, the limiting rod 205 penetrates through the lifting slider 202 and is slidably connected to the lifting slider 202, and the lifting adjusting lead screw 204 is threadedly connected to the lifting slider 202.

[0034] When adjusting the trench digging depth, the lifting adjusting motor 203 operates to drive the lifting adjusting lead screw 204 to rotate. Under the limiting action of the limiting rod 205, the lifting slider 202 is driven to move up and down inside the installation shell 201, thereby driving the trench width adjusting member 4 and the trench opening member 5 to perform lifting adjustment, so as to adjust the trench digging depth, enabling a set of equipment to meet the planting requirements of various different types of vegetables, without the need to frequently replace different models of blades 408, making vegetable planting more convenient and efficient.

[0035] The trench opening member 5 includes a mounting plate 501, a trench opening motor 502, gears 503, and a bulldozing plate 504; the mounting plate 501 is fixedly connected to the outer wall of the protective cover 401, the trench opening motor 502 is fixedly connected to the mounting plate 501, two gears 503 are provided and are both rotatably connected to the mounting plate 501, the two gears 503 are in meshing transmission, the output shaft of the trench opening motor 502 is coaxially fixedly connected to one of the gears 503, the bulldozing plate 504 is fixedly connected to the gear 503, two bulldozing plates 504 are provided and are symmetrically arranged with respect to the two gears 503, and the two bulldozing plates 504 are inclined outward from bottom to top.

[0036] The trench opening motor 502 operates to drive the two gears 503 to rotate in opposite directions, thereby driving the two bulldozing plates 504 to expand or contract, and adjusting the maximum distance of the opening of the bulldozing plates 504, so as to achieve the adjustment of the trench opening width.

[0037] Working principle: Working principle: First, connect the connecting frame 1 to a driving device (such as a tractor), and determine the width and depth parameters of the trench according to the type of vegetables; First, start the servo motor 608 to drive the limiting lead screw 609 to rotate. Under the limiting action of the limiting slider 610 and the limiting chute, the limiting railing 611 moves downward between the blades 408. Next, start the width adjusting motor 402 to rotate it clockwise (taking Figure 1From the perspective of reference), the width adjustment motor 402 operates to drive the bidirectional lead screw 403 to rotate. At this time, the bidirectional lead screw 403 drives the ratchet wheel 601 to rotate. The rotation of the ratchet wheel 601 will squeeze the movable teeth 603 to contract towards the inside of the movable groove. The bidirectional lead screw 403 rotates between the outer mounting cylinder 404 and the inner mounting cylinder 405. Since the limit railing 611 is located between the blades 408 and can limit the outer mounting cylinder 404 and the inner mounting cylinder 405, it will not drive the outer mounting cylinder 404 and the inner mounting cylinder 405 to rotate together.

[0038] Under the limiting effect of the limit railing 611, the outer mounting cylinder 404 and the inner mounting cylinder 405 are driven to move away from or close to each other through the moving frame 406, thereby driving the blades 408 on the outer mounting cylinder 404 and the inner mounting cylinder 405 to move away from or close to each other, changing the overlapping area of the blades 408, and thus changing the width of the trench by changing the working width of the blades 408; Then start the lifting adjustment motor 203 to drive the lifting adjustment lead screw 204 to rotate. Under the limiting effect of the limit rod 205, drive the lifting slider 202 to move up and down in the mounting shell 201, thereby driving the trench width adjustment member 4 and the trenching member 5 to perform lifting adjustment, so as to adjust the trenching depth, enabling a set of equipment to meet the planting requirements of various different types of vegetables, without the need to frequently replace different models of blades 408, making vegetable planting more convenient and efficient; Then it is also necessary to start the trenching motor 502 to operate and drive the two gears 503 to rotate in opposite directions, thereby driving the two earth-moving plates 504 to expand or contract, adjusting the maximum distance of the opening of the earth-moving plates 504, and thus adjusting the trenching width; After the trenching parameters are adjusted, the servo motor 608 rotates in reverse to drive the limit railing 611 to rise away from the blades 408. Then start the width adjustment motor 402 to rotate counterclockwise. At this time, the rotation of the ratchet wheel 601 will drive the movable teeth 603 to rotate together, thereby being able to drive the outer mounting cylinder 404 and the inner mounting cylinder 405 and the blades 408 thereon to rotate synchronously to achieve soil turning; During the process of soil turning and trenching, when the soil resistance sensor 701 detects an increase in the soil resistance, the soil resistance sensor 701 transmits the detected signal to the controller, and the controller controls the vibrator 702 to vibrate, thereby causing the blades 408 to vibrate, preventing clay from accumulating on the blades 408, reducing the load on the blades 408, and improving the trenching efficiency.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution of the present application and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
