Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal material sowing equipment, in particular to sowing equipment for planting astragalus seedlings. Background Art

[0002] Astragalus is a plant of the genus Astragalus in the legume family. It is also known as Northeast Astragalus, Astragalus membranaceus, and Astragalus membranaceus. It is a perennial herb, 50-100 cm tall; the main root is thick and grayish white; the stem is erect, with many branches on the upper part, fine ridges, and covered with white soft hairs.

[0003] There are two main methods of planting astragalus: seed sowing and seedling planting, among which seedling planting is the most common. When the machine for planting astragalus seedlings is actually in operation, a large amount of astragalus to be planted needs to be piled on the top of the equipment in advance, and then multiple workers will sort the astragalus one by one and place them on the conveyor belt. This will result in high labor costs when planting astragalus seedlings. In order to provide a larger growth space for the astragalus seedlings and allow the roots to fully stretch, thereby promoting overall growth, some customers have a demand for oblique planting of astragalus (requiring astragalus to be planted at an angle on the ground surface). However, the equipment currently on the market does not have the function of controlling the placement angle of astragalus during planting, and has limitations when used. Summary of the Invention

[0004] The present invention discloses a sowing device for planting astragalus seedlings, which aims to solve the technical problems that, in actual use, the equipment for planting astragalus seedlings on the existing market requires workers to sort out and arrange the stacked astragalus one by one, which is cumbersome and has high labor costs; on the other hand, some customers have a demand for oblique planting of astragalus, but the equipment on the existing market does not have the function of controlling the placement angle of astragalus during planting, which has limitations in use.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A sowing device for planting astragalus seedlings, comprising a frame, a transport mechanism for stacking and transporting astragalus root is provided on the top of the frame, the transport mechanism comprising a backboard fixedly mounted on the top of the frame, a grid conveyor belt rotatably mounted inside the backboard, a first motor horizontally fixed to the outer side of the backboard, and connected to the grid conveyor belt via a transmission mechanism of the first motor;

[0007] The interior of the transport mechanism is provided with a clamping mechanism for clamping and fixing the end of the astragalus root, the clamping mechanism includes an assembly conveyor belt rotatably mounted on the inner side of the back plate, and a plurality of assembly parts are fixed on the outer side of the assembly conveyor belt;

[0008] The interior of the transport mechanism is also provided with an adjustment mechanism for controlling the angle at which the astragalus is lowered;

[0009] The transport mechanism is used to evenly spread the accumulated astragalus, and the clamping mechanism is used to clamp and transport the astragalus. At the same time, the adjusting mechanism is used to squeeze the astragalus to change the lowering angle of the astragalus.

[0010] By arranging a transport mechanism for stacking and transporting the astragalus on the top of the frame, the transport mechanism is used to disperse the piled astragalus, and then the astragalus is transported in portions through the grating conveyor belt, thereby eliminating the steps of manually sorting and picking the astragalus, and reducing the labor cost during the operation of the equipment. At the same time, the astragalus scattered on the top of the grating conveyor belt will be squeezed and contacted with the clamping mechanism during transportation, so that one end of the astragalus will be clamped by the clamping mechanism during operation. As the grating conveyor belt continues to transport, when the astragalus is in a suspended state, the clamping mechanism can cooperate with the additionally provided adjustment mechanism, so that the astragalus that is lifted on one side will be squeezed by the adjustment mechanism, and thus fall into the field in an inclined state. The inclined distribution can provide the astragalus seedlings with a larger growth space, so that the roots can fully stretch, thereby promoting overall growth, and the degree of inclination of the astragalus is synchronously affected by the adjustment mechanism, thereby greatly improving the convenience and functionality of the use of this equipment.

[0011] In a preferred embodiment, the transport mechanism further includes a cargo box fixedly connected to the end of the backboard, a hair push roller is rotatably installed inside the connecting end of the cargo box and the backboard, a second motor is horizontally fixed on the outer side of the backboard, the output end of the second motor horizontally penetrates into the interior of the cargo box and is transmission-connected to the side of the hair push roller, and a discharge barrel is distributed at the end of the backboard.

[0012] A cargo box is provided to cooperate with the rotation of the grid conveyor belt, and a hair push roller structure driven by a second motor is provided at the end of the cargo box. The rotation of the hair push roller structure is used to cooperate with the grid conveyor belt to drive the astragalus, so that the astragalus pile accumulated inside the cargo box is moved by the hair push roller and dispersed on the grid conveyor belt. At this time, the operator only needs to observe whether the astragalus is evenly distributed on the grid conveyor belt. Different from the traditional astragalus seedling planting equipment, which requires workers to manually peel off individual astragalus from the astragalus pile and discharge the material during operation, this equipment can reduce the labor cost required during operation and improve the convenience of use.

[0013] In a preferred embodiment, the clamping mechanism further includes a sliding member slidably sleeved on the outer side of each assembly member, and a group of elastic clips are fixedly installed on the end of the sliding member, and the end of the astragalus is clamped by the elastic clips. At the same time, a group of fixed clips are fixedly installed on the side of each group of elastic clips, and a paddle is fixedly connected to the side of one of the fixed clips, and the fixed clips and the paddles are horizontally distributed on the side of the grid conveyor belt, and a gap is left between them and the grid conveyor belt.

[0014] By arranging an assembly conveyor belt structure driven synchronously by a second motor on the side of the grid conveyor belt, the assembly conveyor belt is used to drive a number of evenly distributed assembly parts to move synchronously. The moving assembly parts will squeeze and contact the surface of the grid conveyor belt, thereby fitting the shape of the grid conveyor belt, pushing the sliding parts to slide along the surface of the assembly parts, and causing the elastic clip to shrink and clamp one end of the astragalus, thereby ensuring that when the astragalus reaches the side end of the grid conveyor belt, it can be in a state of being lifted on one side. At the same time, the state relationship between the fixed clip and the paddle is coordinated to complete the vertical unloading of the astragalus, thereby ensuring the integrity of the operation of this equipment.

[0015] In a preferred embodiment, the adjustment mechanism includes a shift rod fixedly mounted on the inner side of the back plate, the shift rod and the shift piece are in squeeze contact, and an inclined sleeve rod is also fixed to the inner side of the back plate, the inclined sleeve rod and the shift rod are symmetrical and staggered in the horizontal direction, and an inclined plate is horizontally inserted into the interior of the inclined sleeve rod and is in squeeze contact with the astragalus, and the inclined plate extends to the interior of the discharge barrel.

[0016] By providing a lever structure fixedly installed on the inner side of the back plate and cooperating with a lever structure on the outer side of the fixed clip, the elastic clip that clamps the astragalus is released from the clamping relationship of the astragalus after moving to the specified position, thereby completing the vertical lowering of the astragalus. In this process, the astragalus that is lifted on one side can be squeezed and contacted with the additional inclined plate structure, causing the astragalus to be in an inclined state when it is lowered. The inclination amplitude of the astragalus is affected by the total length of the inclined sleeve and the inclined plate, so that the inclination angle of the astragalus when it is lowered can be controlled, thereby greatly improving the functionality of this device.

[0017] In a preferred solution, a loading spring plate for loading the astragalus is fixedly mounted on the bottom of the loading box, and an extrusion piece is fixedly mounted on the outer side of the hair pushing roller, and the extrusion piece is in extrusion contact with the loading spring plate.

[0018] By additionally arranging an extrusion structure on the outside of the hair push roller, as the hair push roller rotates, the extrusion member will form an extrusion force on the loading spring plate inside the loading box, causing the loading spring plate to bounce intermittently, thereby dispersing the astragalus accumulated inside the loading box, ensuring the integrity of the operation of this equipment.

[0019] In a preferred embodiment, one end of the inclined plate is provided with a convex portion for pressing and contacting the astragalus root, and the other end of the inclined plate is provided with a caliper portion for pressing and engaging with the interior of the inclined sleeve rod.

[0020] A convex portion is provided at one end of the inclined plate to squeeze the astragalus, and a caliper portion is provided at the other end of the inclined plate. The quick-connect relationship between the tooth portion and the inclined sleeve rod is utilized to change the distance from the convex portion to the clamping end of the astragalus, thereby changing the inclination angle of the astragalus and improving the functionality of the device.

[0021] As can be seen from the above, the sowing equipment for planting astragalus seedlings provided by the present invention has the following improvements and advantages compared with the prior art:

[0022] First, a cargo box is provided on the top of the frame to cooperate with the rotation of the grating conveyor belt, and a hair push roller structure driven by a motor is provided at the end of the cargo box. The rotation of the hair push roller structure is used to cooperate with the driving of the grating conveyor belt on the astragalus, so that the astragalus pile accumulated inside the cargo box is pushed by the hair push roller and dispersed on the grating conveyor belt. At the same time, as the hair push roller rotates, the extrusion piece located on the outside of the hair push roller can intermittently push the cargo spring plate provided at the bottom of the cargo box, causing the spring plate to shake, thereby further shaking the accumulated astragalus apart. The operator only needs to observe whether the astragalus is evenly distributed on the grating conveyor belt. Different from the traditional astragalus seedling planting equipment, which requires workers to manually peel off individual astragalus from the astragalus pile and discharge the material during operation, this equipment can reduce the labor cost required during operation and improve the convenience of use.

[0023] Secondly, an assembly conveyor belt structure driven synchronously by a second motor is provided on the side of the grid conveyor belt, and the assembly conveyor belt is used to drive a number of evenly distributed assembly parts to move synchronously. The moving assembly parts will squeeze and contact the surface of the grid conveyor belt, thereby fitting the shape of the grid conveyor belt and pushing the sliding parts to slide along the surface of the assembly parts, causing the elastic clip to shrink and clamp one end of the astragalus, ensuring that when the astragalus reaches the side end of the grid conveyor belt, it can be in a state where one end is lifted, and then combined with the fixed clip, the paddle and the additional arrangement The vertical feeding of the astragalus is completed due to the positional relationship of the lever structure on the inner side of the back plate. In this process, the astragalus that is lifted on one side can be squeezed and contacted with the additional inclined plate structure, so that the astragalus is in an inclined state when it is lowered. The inclined distribution can provide a larger growth space for the astragalus seedlings, so that the roots can fully stretch, thereby promoting overall growth. The inclination amplitude of the astragalus is affected by the total length of the inclined rod and the inclined plate, so that the inclination angle of the astragalus is controllable when it is lowered, thereby greatly improving the convenience and functionality of the device when used.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The sowing equipment for planting astragalus seedlings disclosed by the present invention is mainly used in the scene of sowing and planting astragalus seedlings.

[0040] Reference Figures 1 to 13 A sowing device for planting astragalus seedlings includes a frame 1. A transport mechanism 2 for stacking and transporting astragalus is provided on the top of the frame 1. The transport mechanism 2 includes a backboard 201 fixedly mounted on the top of the frame 1. A grid conveyor belt 202 is rotatably mounted inside the backboard 201. A first motor 203 is horizontally fixed to the outer side of the backboard 201 and is connected to the grid conveyor belt 202 through the first motor 203.

[0041] The transport mechanism 2 is internally provided with a clamping mechanism 3 for clamping and fixing the end of the astragalus root. The clamping mechanism 3 includes an assembly conveyor belt 301 rotatably mounted on the inner side of the back plate 201. A plurality of assembly parts 302 are fixed on the outer side of the assembly conveyor belt 301.

[0042] The interior of the transport mechanism 2 is also provided with an adjustment mechanism 4 for controlling the angle of the astragalus root being lowered;

[0043] The transport mechanism 2 is used to evenly spread the accumulated astragalus, and the clamping mechanism 3 is used to clamp and transport the astragalus. At the same time, the adjusting mechanism 4 is used to squeeze the astragalus to change the lowering angle of the astragalus.

[0044] In this embodiment: when in use, the operator stacks a large number of astragalus seedlings to be planted horizontally inside the transport mechanism 2, and at the same time connects the frame 1 to an external mobile vehicle. At the same time, the operator sits on the top of the frame 1 and uses the mobile vehicle to pull the frame 1 to the field to be sown. After arriving at the designated position, the transport mechanism 2 and the clamping mechanism 3 are started. The running transport mechanism 2 will vibrate and disperse the stacked astragalus, and slowly transport the astragalus toward the other end of the grid conveyor belt 202. During this process, the operator sitting on the frame 1 needs to observe the astragalus distributed on the grid conveyor belt 202. , ensuring that the astragalus on the lattice conveyor belt 202 is stored one by one. At the same time, as the transportation mechanism 2 runs, the synchronously started clamping mechanism 3 will synchronously clamp the end of a single astragalus by squeezing the surface of the lattice conveyor belt 202, and drive the astragalus to move until the astragalus falls off the lattice conveyor belt 202. At this time, the clamping mechanism 3 will continue to drive the astragalus clamped on one side to move in suspension. During this process, the other end of the suspended astragalus will be squeezed and contacted with the adjusting mechanism 4, causing it to tilt and fall off under the influence of the adjusting mechanism 4. The tilted astragalus falls into the field, completing the sowing.

[0045] In the above scheme, in order to ensure the amount of astragalus that can be planted in a single time and the working efficiency of this equipment, the specific operations are as follows.

[0046] Reference Figures 1 to 2 、 Figures 4 to 9 、 Figure 11 In a preferred embodiment, the transport mechanism 2 also includes a backboard 201 whose end is fixedly connected to a cargo box 204, and a hair push roller 205 is rotatably installed inside the connection end between the cargo box 204 and the backboard 201. A second motor 206 is horizontally fixed to the outside of the backboard 201, and the output end of the second motor 206 horizontally penetrates into the interior of the cargo box 204 and is transmission-connected to the side of the hair push roller 205. A discharge barrel 5 is distributed at the end of the backboard 201.

[0047] In this embodiment: when in use, the operator stacks a large number of astragalus seedlings to be planted horizontally inside the cargo box 204, and at the same time connects the frame 1 to an external mobile vehicle. At the same time, the operator sits on the top of the frame 1 and uses the mobile vehicle to pull the frame 1 to the field to be sown. After arriving at the designated position, the first motor 203 and the second motor 206 are started. The first motor 203 will drive the grid conveyor belt 202 to rotate synchronously, and the second motor 206 will drive the hair push roller 205 to rotate. The rotating hair push roller 205 will slowly push the astragalus accumulated inside the cargo box 204 onto the grid conveyor belt 202, and the astragalus located on the grid conveyor belt 202 will be transported to the other end of the grid conveyor belt 202 as it rotates. During this process, the operator sitting on the frame 1 needs to observe the distribution of the astragalus on the grid conveyor belt 202 to ensure that the astragalus on the grid conveyor belt 202 is one grid at a time.

[0048] Among them, it needs to be supplemented that: a loading plate 207 for carrying the astragalus is fixedly installed at the bottom of the loading box 204, and an extrusion piece 208 is fixedly installed on the outside of the hair pushing roller 205. The extrusion piece 208 squeezes and contacts the loading plate 207, and the astragalus stacked inside the loading box 204 is distributed on the top of the loading plate 207. At this time, as the hair pushing roller 205 rotates, the extrusion piece 208 located on the outside of the hair pushing roller 205 will rotate synchronously and intermittently squeeze the end of the loading plate 207, causing the loading plate 207 to bounce and tilt toward the hair pushing roller 205, shaking off the accumulated astragalus and moving it close to the hair pushing roller 205.

[0049] In the above solution, in order to continue to transport the astragalus on the grid conveyor belt 202 for a certain distance, the specific operation is as follows.

[0050] Reference Figures 5 to 7 、 Figures 9 to 11In a preferred embodiment, the clamping mechanism 3 also includes a sliding member 303 slidably sleeved on the outer side of each assembly member 302, and a group of elastic clips 304 are fixedly installed on the end of the sliding member 303, and the elastic clips 304 are used to clamp the end of the astragalus. At the same time, a group of fixed clips 305 are fixedly installed on the side of each group of elastic clips 304, and a paddle 306 is fixedly connected to the side of a fixed clip 305. The fixed clips 305 and the paddle 306 are horizontally distributed on the side of the grid conveyor belt 202, and a gap is left between them and the grid conveyor belt 202.

[0051] In this embodiment: as the grid conveyor belt 202 runs, the synchronously started second motor 206 will synchronously drive the assembly conveyor belt 301 to rotate, and the rotating assembly conveyor belt 301 will drive several assembly parts 302 to rotate synchronously until the sliding part 303 and the elastic clip 304 at the bottom of the assembly part 302 are squeezed and contacted with the surface of the grid conveyor belt 202. At this time, the elastic clip 304 restricted by the squeeze will gather in the center and clamp the end of the astragalus. At the same time, the fixed clip 305 located on the outside of the elastic clip 304 will be driven to gather and adhere synchronously. The specific state is as follows: Figure 5 As shown; at this time, the elastic clip 304 that continues to move will drive the astragalus to move until the astragalus falls off the grid conveyor belt 202. At this time, the elastic clip 304 will continue to drive the astragalus clamped on one side to move in mid-air until the other end of the astragalus is squeezed and contacts the adjustment mechanism 4, and the astragalus will fall off the elastic clip 304 and fall into the field in an inclined state; wherein, a magnetic attraction member 307 is installed on the inner side of each set of fixed clips 305, and two magnetic attraction members 307 that are symmetrically distributed and close to each other are adsorbed and fixed, thereby maintaining the close clamping state of the elastic clip 304; and a transmission belt 309 is connected to the transmission sleeve between the assembly conveyor belt 301 and the second motor 206.

[0052] Furthermore, a spring 308 is fixedly connected between each assembly part 302 and the sliding part 303. When the sliding part 303 and the elastic clip 304 located at the bottom of the assembly part 302 are squeezed and contacted with the surface of the grid conveyor belt 202, the sliding part 303 will overcome the resistance of the spring 308 and slide vertically along the outside of the assembly part 302, thereby adapting to the distance between the sliding part 303 and the grid conveyor belt 202.

[0053] In the above scheme, in order to make the astragalus root in an inclined state when lowered, a larger growth space is provided for the astragalus root seedlings, so that the roots can fully stretch, thereby promoting overall growth. The specific operations are as follows.

[0054] Reference Figure 1 and Figure 3In a preferred embodiment, the adjustment mechanism 4 includes a shift rod 401 fixedly mounted on the inner side of the back plate 201, the shift rod 401 and the shift piece 306 are in squeeze contact, and an inclined sleeve rod 402 is also fixed to the inner side of the back plate 201, the inclined sleeve rod 402 and the shift rod 401 are symmetrical and staggered in the horizontal direction, and an inclined plate 403 is horizontally inserted into the interior of the inclined sleeve rod 402 and is in squeeze contact with the astragalus, and the inclined plate 403 extends to the interior of the discharge barrel 5.

[0055] In this embodiment, the continuously moving elastic clip 304 will drive the astragalus to move until it falls off the grating conveyor belt 202. At this time, the elastic clip 304 will continue to drive the astragalus clamped on one side to move in the air until the other end of the astragalus is squeezed and contacts the inclined plate 403 on the outside of the inclined sleeve rod 402. Pushed by the inclined plate 403, the horizontally distributed astragalus will become inclined. At the same time, the paddle 306 on the side of the fixed clip 305 will squeeze and contact the paddle 401, thereby being pushed by the paddle 401, driving the two fixed clips 305 adsorbed to each other to reset and expand. The expanded fixed clip 305 will synchronously drive the elastic clip 304, causing the astragalus to fall off the reset and expanded elastic clip 304 and fall from the discharge barrel 5 to the field in an inclined state. The discharge barrel 5 can play a role in The function of shielding from wind; wherein, one end of the inclined plate 403 is provided with a convex portion 404 for squeezing and contacting the astragalus, and the other end of the inclined plate 403 is provided with a caliper portion 405 for squeezing and engaging with the inside of the inclined sleeve rod 402. When the user needs to adjust the inclination angle of the astragalus, the user pulls out the inclined plate 403 from the end of the inclined sleeve rod 402 and re-inserts it into the inside of the inclined sleeve rod 402, thereby changing the total length of the inclined plate 403 and the inclined sleeve rod 402, and changing the distance from the convex portion 404 at the end of the inclined plate 403 to the clamped end of the astragalus, thereby changing the amplitude of the squeezing of the astragalus, and the inclined plate 403 extending to the inside of the discharge barrel 5 can always provide a limited shielding for the inclined astragalus, so that the astragalus cannot be reset and straightened, and when the equipment is in operation, the field ground is in a flat state, and there is no need to dig trenches, so as to keep the astragalus in the state when it falls to the ground.

[0056] It should be noted that the astragalus seedlings have toughness, and when the elastic clip 304 clamps one end of the astragalus seedlings, it will not cause the astragalus seedlings to droop.

[0057] Working principle: When in use, the operator stacks a large number of astragalus seedlings to be planted horizontally inside the cargo box 204, and connects the frame 1 to the external mobile vehicle. At the same time, the operator sits on the top of the frame 1 and uses the mobile vehicle to pull the frame 1 to the field to be sown. After arriving at the designated position, the first motor 203 and the second motor 206 are started. The first motor 203 will drive the grid conveyor belt 202 to rotate synchronously, and the second motor 206 will drive the hair push roller 205 to rotate. The rotating hair push roller 205 will slowly push the astragalus accumulated in the cargo box 204 onto the grid conveyor belt 202, and the astragalus located on the grid conveyor belt 202 will be transported to the other end of the grid conveyor belt 202 as it rotates. In this process, the operator sits on the frame 1 The operator on the grid conveyor belt 202 needs to observe the distribution of the astragalus on the grid conveyor belt 202 to ensure that the astragalus on the grid conveyor belt 202 is one grid at a time. As the grid conveyor belt 202 runs, the second motor 206 that starts synchronously will synchronously drive the assembly conveyor belt 301 to rotate, and the rotating assembly conveyor belt 301 will drive several assembly parts 302 to rotate synchronously until the sliding part 303 and the elastic clip 304 at the bottom of the assembly part 302 are squeezed and contacted with the surface of the grid conveyor belt 202. At this time, the elastic clip 304 that is restricted by the squeezing will gather in the center and clamp the end of the astragalus. At the same time, the fixed clip 305 located on the outside of the elastic clip 304 will be driven and affected by the magnetic suction part 307 to gather and adhere synchronously. The specific state is as follows: Figure 5 As shown; at this time, the elastic clip 304 that continues to move will drive the astragalus to move until the astragalus falls off the grid conveyor belt 202. At this time, the elastic clip 304 will continue to drive the astragalus clamped on one side to move in the air until the other end of the astragalus is squeezed and contacts the inclined plate 403 outside the inclined sleeve rod 402. Pushed by the inclined plate 403, the horizontally distributed astragalus will become inclined. The specific state is as shown in FIG. Figure 12 As shown; at the same time, the paddle 306 located on the side of the fixed clip 305 will squeeze and contact the paddle 401, thereby being pushed by the paddle 401, driving the two fixed clips 305 that are attracted to each other to reset and expand, and the expanded fixed clip 305 will synchronously drive the elastic clip 304, thereby causing the astragalus to fall off from the reset and expanded elastic clip 304 and fall from the inside of the discharge barrel 5 to the field in an inclined state, completing the sowing of a single astragalus seedling (the astragalus seedling is first interfered by the inclined plate 403 and tilted before falling to the field); and when the user needs to adjust the inclination angle of the astragalus, the user pulls out the inclined plate 403 from the end of the inclined sleeve rod 402 and re-inserts it into the inside of the inclined sleeve rod 402, changing the total length of the inclined plate 403 and the inclined sleeve rod 402, and changing the distance from the convex portion 404 at the end of the inclined plate 403 to the clamped end of the astragalus, thereby changing the amplitude of the squeezing of the astragalus.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
