Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of pepper machine sowing, and particularly relates to a pepper pelletized seed cultivation device. Background Art
[0002] Seed pelleting technology is a modern agricultural seed processing technology that wraps seeds in a shell made of adhesives, fillers, nutrients, pharmaceuticals and other materials to make them into pellets of uniform size and regular shape, thereby improving sowing efficiency, germination quality and crop resistance.
[0003] A pelletized seed cultivation system typically consists of a seed storage device, a seed meter, a seed conveyor, a furrow opener, a soil covering and suppression device, a power drive system, and an operation and control system. The seed storage device stores the seeds, the seed meter precisely controls seed discharge, the seed conveyor delivers the seeds to the sowing location, the furrow opener creates the sowing furrow in the soil, the soil covering and suppression device provides soil covering and suppression, the power drive system provides power for each component, and the operation and control system provides control and parameter settings.
[0004] Current pelletized seed cultivation and sowing devices generally use vibration and centrifugation to discharge seeds. During this process, it is easy to cause microcracks or even partial peeling of the brittle coating shell. These mechanical damages directly weaken the protective function of the seed shell against pesticides and micro-fertilizers, affecting field emergence. Summary of the Invention
[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention aims at the problem that the mechanical seed-draining device in the pelletized seed cultivation device easily causes the seed shell of the pelletized seed to be damaged. The method adopts a method of guiding the seeds to be discharged with water flow and then using a piston to cooperate with a micro-flexible opening and closing port to suck the seeds for sowing. A seed-draining mechanism with an upper water spray port and a lower water suction port is provided to form a circulating water flow to guide the pelletized seeds at the bottom of the seed bin into the suction hole position, and an opening and closing port is opened by using an open conical ring in combination with a flexible film and opened when the locking mechanism is opened and the piston is sucked. With the intervention of the piston, electromagnet, piezoresistor and proximity sensor, the seed-draining and sowing of the pelletized seeds is realized in the full water environment protection, thereby avoiding the mechanical damage that may be caused in the process of seeding the pelletized seeds, and solving the problem that seeding by vibration and centrifugation is easy to cause the seed shell of the pelletized seeds to be damaged, thereby affecting the seed germination rate, which is difficult to solve in the prior art.
[0006] This solution provides a pepper pelletized seed cultivation device. By setting up a water flow to guide the seeds to be planted, and then using a piston to cooperate with a micro-flexible opening and closing port to suck the seeds for sowing, the device can realize the function of pre-wetting the pelletized seeds and accurately sowing them without damage.
[0007] The technical solution adopted in this scheme is as follows: The chili pill granulated seed cultivation device proposed in this scheme includes a funnel bin, a seed supply mechanism, a circulating water mechanism, a suction mechanism, a sowing mechanism, a frame, a seed bin, a loosening wheel and a leveling wheel. The loosening wheel and the leveling wheel are arranged at the bottom of the front and rear sides of the frame, the seed bin is fixed on the frame, the funnel bin is connected to the bottom of the seed bin, multiple groups of seed supply mechanisms are connected to the bottom of the funnel bin, the circulating water mechanism is connected to the side faces of multiple groups of seed supply mechanisms, the seed supply mechanism includes a locking mechanism and two groups of seed discharge mechanisms, the suction mechanism is connected to the bottom of the seed discharge mechanism, the sowing mechanism is arranged below the circulating water mechanism, and the sowing mechanism is connected to the suction mechanism.
[0008] As a further preferred embodiment of the present invention, the seeding mechanism includes a seeding trough, a gap separation pipe, an upper nozzle, a water pumping trough, a suction pipe, an inclined guide surface, a water pumping port, a membrane type opening and closing port and a water through hole. The edge of the seeding trough is connected to the bottom of the funnel bin, the water pumping trough is arranged below the seeding trough, multiple groups of the suction pipes are arranged through the water pumping trough, the inclined guide surface is arranged at the connection between the suction pipe and the bottom plate of the seeding trough, multiple groups of the water pumping ports are opened on the inclined guide surface, the membrane type opening and closing port covers and is connected above the inclined guide surface, the membrane type opening and closing port is made of soft and elastic material, multiple groups of the water through holes are opened on the membrane type opening and closing port, the water pumping trough is connected to the seeding trough through the water pumping port and the water through hole, multiple groups of the gap separation pipes are arranged above the bottom surface of the seeding trough, the gap separation pipes are arranged at the gap of the suction pipe and have smooth edges, and multiple groups of the upper nozzles are opened at the top of the gap separation pipes.
[0009] When in use, the seed trough accommodates the pelletized seeds that descend from the funnel bin into the seed supply mechanism. The pelletized seeds fall above the opening of the suction tube along the gap separation tube and the inclined guide surface contour under the action of gravity and the squeezing of the seeds above. In this process, the upper nozzle located at the gap position of the suction tube sprays an upward flow of water and the water suction port below the suction tube continuously draws water from the seed trough to guide the pelletized seeds. Subsequently, the pelletized seeds contact the membrane opening and closing port of the soft material above the suction tube to block the inlet of the suction tube and partially block the water hole, so that the suction force on the side and bottom of the pelletized seeds is increased, thereby pressing the pelletized seeds tightly above the membrane opening and closing port.
[0010] Preferably, the locking mechanism includes a transmission rod, which is inserted into the water suction trough of the two sets of seed-discharging mechanisms and is slidingly and sealingly connected to the outer wall thereof. The seed-discharging mechanism also includes a locking ring, which is an open conical ring made of a plastic strip. One end of the locking ring is connected to the edge of the water suction port, and the other end is connected to the transmission rod. The locking ring surrounds the outer side of the middle part of the membrane-type opening and closing port.
[0011] When in use, when the locking ring is not opened, the locking ring surrounds the outside of the membrane opening and closing port to prevent the pelletized seeds from entering the suction tube through the membrane opening and closing port. The locking ring supports the pelletized seeds. Since the pelletized seeds act on the inclined conical surface inside the locking ring through the membrane opening and closing port, the locking ring has a tendency to open. When the force of the pelletized seeds is large enough, multiple sets of locking rings open and drive the transmission rod to move.
[0012] Specifically, the locking mechanism also includes a locking mechanism housing, a rotating member 1, a rotating member 2, a transmission rotating member, a connecting rod, a linkage plate, an L-shaped matching member, an inclined plate matching member, an electromagnet 1 and a magnet, the locking mechanism housing is fixed to the side of the seed-seeding mechanism, the rotating member 1 and the rotating member 2 are rotatably connected to the inside of the locking mechanism housing, the transmission rotating member is connected to the side of the top end of the rotating member 1 and extends radially along the rotation direction of the rotating member 1, one end of the connecting rod is rotatably connected to the end of the transmission rotating member away from the rotating member 1, the other end of the connecting rod is rotatably connected to the end of the transmission rod away from the seed-seeding mechanism, the linkage plate is fixedly connected to the side of the rotating member 1 and extends radially along the rotation direction of the rotating member 1, the rotating member 2 rotates The cam is fixedly connected to the side of the second rotating part and is provided with an L-shaped fitting part and an inclined plate fitting part. The L-shaped fitting part has an L-shaped structure and can limit the rotation of the linkage plate by the short side away from the second rotating part. The inclined plate fitting part has an inclined surface structure at a section away from the second rotating part. The inclined surface structure can push the L-shaped fitting part to rotate to a position where the linkage plate is limited to move via the rotating linkage plate. A magnet is provided on the outside of the long side of the L-shaped structure of the L-shaped fitting part, and an electromagnet is provided on the side of the magnet away from the linkage plate. The seeding mechanism also includes a varistor. The locking ring is connected to the transmission rod via the varistor, and the varistor is connected to the power supply circuit of the electromagnet.
[0013] When in use, the transmission rod moves to drive the connecting rod to move, and the connecting rod drives the linkage plate to rotate through the transmission rotating part. The short side of the L-shaped structure in the initial position of the L-shaped fitting blocks the rotation of the linkage plate. When the pelletized seeds are pressed against the membrane opening and closing port and act on the locking ring, the locking ring has a tendency to open and acts on the piezoresistor, and the resistance inside the piezoresistor decreases. When the resistance inside all the piezoresistors on the two sets of seed-discharging mechanisms decreases, the electromagnet is briefly started, and its output end acts on the magnet and drives the L-shaped fitting and the inclined plate fitting to rotate a certain angle and releases the blocking of the linkage plate by the L-shaped fitting. The transmission rod can only move at this time. When the transmission rod moves to the locking ring and opens close to the maximum extent, the pelletized seeds can enter the suction pipe through the membrane opening and closing port. At this time, the rotational inertia of the transmission rotating part drives the linkage plate to continue rotating. The locking ring and the transmission rod are reset. During this process, the linkage plate pushes the inclined plate fitting to make the short side of the L-shaped structure of the L-shaped fitting return to the position that limits the rotation of the linkage plate. Through this process, the purpose of only opening the locking ring in one group of seed supply mechanisms once the electromagnet is started and releasing a fixed number of pelletized seeds is achieved.
[0014] Among them, the seed-discharging mechanism also includes a circulating water inlet pipe, a circulating water outlet pipe and a collecting pipe. The circulating water inlet pipe is arranged on the side of the seed-discharging trough and is connected to multiple groups of gap separation pipes. The circulating water outlet pipe is arranged on the side of the water pumping trough and is connected thereto. The upper end of the collecting pipe has multiple groups of interfaces, and the bottom ends of the multiple groups of suction pipes in the seed-discharging mechanism are connected to the upper end of the collecting pipe through pipes.
[0015] When in use, the circulating water inlet pipe is connected with the water supply pipe to introduce the water in the water tank into the seeding mechanism and spray it into the seeding trough upwards, which has the effect of impacting the pelletized seeds above the seeding mechanism to prevent them from accumulating and clogging and guiding the pelletized seeds to fall above the suction pipe. The circulating water outlet pipe is connected with the water pumping pipe, and the water in the water pumping trough is pumped back into the water tank through the water pumping pump, so that the water pumping port opened on the water pumping trough can generate suction above to guide the pelletized seeds to fall above the suction pipe and press it against the membrane opening and closing port to facilitate subsequent seed absorption. The collecting pipe collects the pelletized seeds discharged from each group of seeding mechanisms separately and guides them to the subsequent pipelines.
[0016] Preferably, the circulating water mechanism includes a water tank, a water supply pipe, a solenoid valve, a water suction pipe and a water pump. The water tank is located above the water supply mechanism. Multiple groups of water supply pipes are connected to the side of the water tank. The water supply pipe is arranged on the solenoid valve. The solenoid valve can control the flow cross-section in the water supply pipe. The end of the water supply pipe away from the water tank is connected to the circulating water inlet pipe, one side of the water suction pipe is connected to the water tank, and the side away from the water tank is connected to multiple groups of circulating water outlet pipes. A water pump is provided in the middle of the water suction pipe.
[0017] During use, the water in the water tank enters the seed-discharging mechanism through the water supply pipe, and the water pressure generated by the water level difference impacts the pelletized seeds above the seed-discharging mechanism to prevent them from accumulating and clogging. The solenoid valve can suspend the circulating water supply when the water level in the lower part of the funnel bin is too high and provide a flow rate adjustment function to generate a variable impact force to further prevent the pelletized seeds from accumulating above the seed-discharging mechanism. The excess water in the seed-discharging mechanism is pumped back to the water tank through the water pump through the water pump to maintain the water level in the lower part of the funnel bin to prevent the pelletized seeds from soaking for too long and provide downward suction force in the seed-discharging mechanism.
[0018] Furthermore, the suction mechanism is connected to the lower end of the collecting pipe, and the suction mechanism includes a piston cylinder, a piston rod, an electromagnet 2 and a side nozzle. The piston rod is arranged inside the piston cylinder, the electromagnet 2 is arranged at the bottom end of the piston cylinder, the output end of the electromagnet 2 acts on the bottom of the piston rod, and the side nozzle is connected to the middle of the side of the piston cylinder.
[0019] During use, when the electromagnet 2 is started, the upper output end generates magnetic force to attract the piston rod downward, and the piston rod moves downward along the piston cylinder. The water and the pelletized seeds in the collecting pipe connected to the seed-discharging mechanism above the suction mechanism are sucked into the piston cylinder and discharged from the side nozzle when the piston rod moves below the side nozzle.
[0020] Furthermore, the sowing mechanism includes a sowing support frame and a sowing assembly, the sowing support frame is arranged below the circulating water mechanism, two groups of the sowing assemblies are connected below the sowing support frame, the sowing assembly includes a sliding block, a sowing tube, a seed collecting pipe head and a furrow opener, the sliding block is horizontally slidably connected to the sowing support frame, the sowing tube passes through the sliding block and is fixedly connected thereto, the seed collecting pipe head is arranged at the top of the sowing pipe, the seed collecting pipe head is connected to the side nozzle connected to the bottom of each seed discharge mechanism in multiple groups of seed supply mechanisms through a hose, and the furrow opener is arranged on the side of the sowing pipe close to the loosening wheel.
[0021] When in use, the sowing component can slide horizontally along the sowing support frame, thereby controlling the row spacing of the pepper pelletized seeds. The seed collecting pipe head above each sowing component is connected to one of the two groups of suction mechanisms connected below each group of seed supply mechanisms. The water and pelletized seeds in the suction mechanism enter the sowing pipe through the seed collecting pipe head and are finally sown on the land. The furrow opener can break a groove of appropriate width to provide an environment for the pepper pelletized seeds to germinate.
[0022] Furthermore, the funnel bin has a funnel-shaped structure that is wide at the top and narrow at the bottom. A water level alarm is provided at the lower part of the funnel bin. One end of the water level alarm is provided inside the funnel bin. The water level alarm is connected to the power circuit of the water pump.
[0023] During use, a small amount of water will be stored at the bottom of the funnel bin. When the water level reaches the position of the water level alarm, the water level alarm will trigger an alarm and increase the working power of the water pump until the water level alarm no longer triggers an alarm, thereby preventing the water level in the funnel bin from being too high and soaking too many seeds to be sown.
[0024] Furthermore, it also includes a displacement sensor and an induction marker. The displacement sensor is arranged on the frame close to the loosening wheel, and multiple groups of induction markers are arranged on the side of the loosening wheel and opposite to it. The displacement sensor is integrated with a control unit, and the control unit in the displacement sensor is also electrically connected to electromagnet 2, electromagnet 1 and the solenoid valve.
[0025] When in use, the device moves forward, and the loosening wheel rolls to drive multiple groups to rotate. The displacement sensor collects displacement data of the sensing identification device in front of it by sensing it. At fixed planting intervals, it sends a start signal to the electromagnet 2 in each group of seed supply mechanism to start it, thereby planting the seeds in the specified position. When the electromagnet 1 is started, an unlocked signal is sent to the control unit integrated in the displacement sensor. Before a new round of startup of a group of electromagnets 2, if the corresponding electromagnet 1 does not send an unlocked signal, the group of seed supply mechanism is skipped, and a signal is sent to the corresponding solenoid valve connected to it to increase the flow cross-section, so as to increase the water inlet impact force in the seeding mechanism and solve the seed blockage problem therein.
[0026] The beneficial effects achieved by adopting the above structure are as follows:
[0027] (1) Compared with the prior art, the present invention sets a water suction port under the suction hole and sets an upper nozzle at the gap to guide the pelletized seeds at the bottom of the seed bin into the seed discharging mechanism at a designated position, so that the pelletized seeds can be gently sorted and discharged in a water environment, avoiding the damage to the shell of the pelletized seeds caused by mechanical means such as vibration and centrifugation, which would cause a decrease in the germination rate.
[0028] (2) Compared with the prior art, the present invention sets an opening and closing port which is opened by a locking mechanism and a piston suction, and cooperates with the suction mechanism to enable tiny pelletized seeds to pass through the suction hole position one by one. The control unit coordinates the output of multiple groups of seed arrangement structures to avoid partial blockage affecting the seed supply. The water flow is used by the suction mechanism to drive the pelletized seeds to be discharged quickly, preventing missed sowing and inaccurate sowing position, so that the device has higher stability in precise sowing.
[0029] (3) Compared with the prior art, the present invention places the pelletized seeds to be sown into the soil in a short time by placing them into a water-filled seed-discharging mechanism and controlling the water level at the bottom of the seed bin. The surface of the pelletized seeds is coated with a layer of seed coating agent. Pre-wetting can make the seeds absorb water more easily, and the surface of the seeds becomes moist after being wetted, making it easier for them to come into close contact with the soil, thereby improving the quality and effect of sowing.

The sowing assembly 52 includes a sliding block 521, a sowing tube 522, a seed collecting pipe head 523 and a furrow opener 524. The sliding block 521 is horizontally slidably connected to the sowing support frame 51. The sowing tube 522 passes through the sliding block 521 and is fixedly connected thereto. The seed collecting pipe head 523 is arranged at the top of the sowing pipe 522. The seed collecting pipe head 523 is connected to the side nozzle 44 connected to the bottom of each seed discharging mechanism 22 in the multiple groups of seed supply mechanisms 2 through a hose. The furrow opener 524 is arranged on the side of the sowing pipe 522 close to the loosening wheel 8.
[0055] like Figure 3 As shown, the funnel bin 1 has a funnel-shaped structure that is wide at the top and narrow at the bottom. A water level alarm 11 is provided at the lower part of the funnel bin 1. One end of the water level alarm 11 is provided inside the funnel bin 1. The water level alarm 11 is connected to the power circuit of the water pump 35.
[0056] like Figure 1 As shown, it also includes a displacement sensor 61 and an induction mark 81. The displacement sensor 61 is arranged on the frame 6 close to the loosening wheel 8. Multiple groups of induction marks 81 are arranged on the side of the loosening wheel 8 and arranged opposite to 61. The displacement sensor 61 is integrated with a control unit. The control unit in the displacement sensor 61 is also electrically connected to the electromagnet 2 43, the electromagnet 1 2110 and the solenoid valve 33.
[0057] During specific use, in Example 1, first, adjust the horizontal distance between the two sets of sliding blocks 521 to meet the planting row spacing, open the solenoid valve 33 and start the water pump 35, and the pelletized seeds stored in the seed bin 7 enter the seed supply mechanism 2 through the funnel bin 1, and the water in the water tank 31 enters the seed discharging mechanism 22 through the water supply pipe 32, and the water pressure generated by the water level difference impacts the pelletized seeds above the seed supply mechanism 2 to prevent them from accumulating and clogging, and the excess water in the seed supply mechanism 2 is pumped back to the water tank 31 through the water pump 35 through the water pump 34 to maintain the water level at the bottom of the funnel bin 1 to prevent the pelletized seeds from soaking for too long, and the pelletized seeds fall above the opening of the suction pipe 226 along the contour of the gap partition tube 222 and the inclined guide surface 227 under the action of gravity and the squeezing of the seeds above. In this process, the upper nozzle 223 located at the gap position of the suction pipe 226 sprays an upward flow of water and suctions The water suction port 2271 below the tube 226 continuously draws water from the seed discharging groove 221 to guide the pelletized seeds. Then the pelletized seeds contact the membrane opening and closing port 228 made of soft material above the suction tube 226 to block the inlet of the suction tube 226 and partially block the water hole 2281, so that the suction force on the side and bottom of the pelletized seeds increases, thereby pressing the pelletized seeds against the membrane opening and closing port 228 and acting on the locking ring 229. The locking ring 229 has a tendency to open and acts on the piezoresistor 2291, and the resistance inside the piezoresistor 2291 decreases. When the resistance inside all the piezoresistors 2291 on the two sets of seed discharging mechanisms 22 decreases, the electromagnet 2110 is briefly started, and its output end acts on the magnet 2111 and drives the L-shaped fitting 218 and the inclined plate fitting 219 to rotate a certain angle and release the blocking of the linkage plate 217 by the L-shaped fitting 218.
[0058] At the same time, the device moves forward, the furrow opener 524 is inserted into the soil to break a furrow of appropriate width, the loosening wheel 8 rolls and drives the multiple groups 81 to rotate, and the displacement sensor 61 collects the displacement data of the device by sensing the 81 rotating in front. The displacement sensor 61 sends a start signal to the electromagnet 2 43 in each group of seed supply mechanism 2 at fixed planting intervals to start it. After the electromagnet 2 43 is started, the upper output end generates a magnetic force to attract the piston rod 42 downward, and the piston rod 42 moves downward along the piston cylinder 41. A suction force is generated in the suction pipe 226 connected to the upper part of the piston cylinder 41 to suck the pelletized seeds downward. Under the action of the pelletized seeds, the multiple groups of locking rings 229 open and drive the transmission rod 211 to move. When the transmission rod 211 moves to the locking ring 229 and opens to a near maximum extent, the pelletized seeds can enter the suction pipe 226 through the membrane opening and closing port 228. Thereafter, the rotational inertia of the transmission rotating member 215 drives the linkage plate 217 to continue rotating. The locking ring 229 and the transmission rod 211 are reset. During this process, the linkage plate 217 pushes the inclined plate fitting 219 to make the short side of the L-shaped structure of the L-shaped fitting 218 return to the position to limit the rotation of the linkage plate 217 to limit the movement of the transmission rod 211 and prevent the locking ring 229 from opening again. Subsequently, the water and the pelletized seeds in the collecting pipe 2211 of the seed-discharging mechanism 22 connected to the top of the suction mechanism 4 are sucked into the piston cylinder 41 and are discharged from the side nozzle 44 through the sowing pipe 522 when the piston rod 42 moves to the bottom of the side nozzle 44 to complete the sowing.
[0059] Embodiment 2, this embodiment is based on the above embodiment. When the water level at the bottom of the funnel bin 1 reaches the position of the water level alarm 11, the water level alarm 11 triggers an alarm and increases the working power of the water pump 35 until the water level alarm 11 no longer triggers an alarm, thereby preventing the water level in the funnel bin 1 from being too high to soak the seeds to be sown and unable to be sown in time.
[0060] Example 3: This example is based on the above example, with reference to Figure 15 When the electromagnet 1 2110 is started, it sends an unlocked signal to the displacement sensor 61. Before a new round of starting of a group of electromagnets 2 43, if the corresponding electromagnet 1 2110 does not send an unlocked signal, the seed supply mechanism 2 of this group will be skipped, and a signal will be sent to the corresponding electromagnetic valve 33 to increase the flow cross-section, so as to increase the water inflow impact in the seeding mechanism 22 to solve the seed blockage problem.
