Description

Technical Field

[0002] The seedling drill is used to sow seeds on seedling trays with substrates. A seed bin is provided on the drum, and the rotation of the drum will accurately sow the seeds in the hopper onto the substrate through the seed bin.

[0003] For seeds of different particle sizes, it is necessary to replace the drum with seed bins of different sizes. When replacing the drum, the existing drum needs to be removed and then the new drum is installed. The existing method of removing the drum is to remove the support part on one side of the drum and then remove the drum from the drive shaft.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1-12 As shown, the present embodiment provides a novel seed drill, including a frame 1 and a transmission system 2, the frame 1 and the transmission system 2 are rotatably connected, the frame 1 is detachably connected with a support assembly 100, the support assembly 100 is rotatably connected with a roller 300, both ends of the roller 300 are rotatably connected with auxiliary assemblies 500, the auxiliary assembly 500 is rotatably connected to the support assembly 100, the support assembly 100 is also detachably connected with a feeding assembly 400, the feeding assembly 400 is rotatably connected to the roller 300, the frame 1 is also detachably connected with an adjusting assembly 200, the adjusting assembly 200 is detachably connected to the roller 300, the support assembly 100 is detachably connected with a driving member 106, the driving member 106 is detachably connected with the driving member 106, and the driving member 106 is detachably connected with the driving member 106. The moving part 106 is rotatably connected to one end of the drum 300 through a power transmission part; the drum 300 includes a silo 330, and the two ends of the silo 330 are symmetrically and slidably connected with fixed rings 310, and a disassembly assembly 320 and a counterweight rod 340 are respectively installed between the two fixed rings 310, and the two ends of the disassembly assembly 320 are respectively rotatably connected to the two fixed rings 310, and the two ends of the counterweight rod 340 are respectively detachably connected to the two fixed rings 310, and the disassembly assembly 320 is meshedly connected to the silo 330, and the sides of the two disassembly assemblies 320 are fixedly connected with a driving shaft 315, and the driving shaft 315 is detachably connected to the adjusting assembly 200, and the driving shaft 315 is respectively rotatably connected to the auxiliary assembly 500 and the bracket assembly 100.

[0034] This embodiment is a sowing link on the production line. The frame 1 is connected to the frame 1 of other links, and the transmission system 2 is also connected to other links. The frame 1 is used to support the equipment off the ground, and the transmission system 2 is used to drive the seedling tray to flow in each link. The general links are: taking the seedling tray, covering the soil, sowing, watering, secondary covering the soil (as needed), covering the film (as needed), and finally transporting the seedling tray to the seedling raising link for subsequent work; fill the seeds on the feeding assembly 400 in advance, and when the seedling tray is about to be transported to the bottom of the seed drill by the transmission system 2, the driving member 106 drives the driving shaft 315, and the driving shaft 315 drives the silo 330. At this time, the silo 3 30 starts to take out the seeds in the feeding assembly 400, and the auxiliary assembly 500 sweeps the excess seeds back into the feeding assembly 400. The auxiliary assembly 500 also keeps the seeds in the silo 330 on the silo 330 until the seeds in the silo 330 rotate to above the seedling tray. The auxiliary assembly 500 releases the retention of the seeds in the silo 330, allowing the seeds to fall on the seedling tray. As the transmission system 2 drives the seedling tray to operate, the seeds are evenly scattered on the seedling tray. According to the height of different seedling trays or the height of the substrate in the seedling tray, the distance between the roller 300 and the seedling tray or the substrate can be adjusted by adjusting the assembly 200, so that height adjustment can be achieved. When replacing seeds of different diameters, first lift the auxiliary component 500, press the disassembly component 320 at the end away from the driving member 106 with a screwdriver, a board or other tool and rotate it in the opposite direction to remove the silo 330 from the fixing ring 310, replace the silo 330 that is adapted to the current seed diameter, then use a screwdriver, a board or other tool to not press the disassembly component 320 at the end away from the driving member 106 and rotate it in the forward direction to make the head and tail of the silo 330 contact each other, reduce the distance of the connecting seam 334 to the minimum, and finally put down the auxiliary component 500 to start sowing. In this embodiment, the distance of the connecting seam 334 is less than the distance of the seed diameter. No seeds will be stuck in the connecting seam 334; because the counterweight rod 340 installed on the drum 300 is used to balance the weight of the disassembly and assembly component 320, when the drum 300 rotates at high speed, the drum 300 will maintain balance and rotate more stably. This replacement method that adapts to different seed diameters can maintain the accuracy of sowing and is more convenient for disassembly; the present invention uses the adjustment component 200, and the height adjustment is simple and accurate. It can adapt to seedling trays of different thicknesses and the matrix in the seedling tray. Through the cooperation of the disassembly and assembly component 320 and the fixing ring 310, the silo 330 that adapts to different seed diameters can be simply and quickly replaced without affecting the sowing accuracy.

[0035] Furthermore, a limit groove 312, a disassembly groove 311 and a sliding groove 314 are provided on the fixed ring 310, the limit groove 312 is respectively connected with the disassembly groove 311 and the sliding groove 314, and the two ends of the silo 330 are respectively slidably connected with the limit groove 312 and the disassembly groove 311, a rack is fixedly connected to the position of the silo 330 near the sliding groove 314, the rack is meshed with the disassembly assembly 320, a limit block 313 is fixedly connected in the limit groove 312, and the limit block 313 abuts against the silo 330.

[0036] The two fixing rings 310 are symmetrically arranged, and a pressing piece is arranged in the limiting groove 312. When the silo 330 is inserted into the limiting groove 312, the pressing piece will firmly press the silo 330 into the limiting groove 312. Even if the silo 330 is installed and removed frequently for many times, the silo 330 will not produce abrasive activities in the limiting groove 312 due to friction, thereby further ensuring the sowing accuracy. When installing the silo 330, the end of the silo 330 without the rack is inserted into the limiting groove 312 from the disassembly groove 311 to make the silo 330 and the silo 330 close to each other. The limit block 313 is abutted, and then the silo 330 is bent so that the end of the silo 330 with the rack extends from the disassembly groove 311 into the limit groove 312. At this time, the rack engages with the disassembly assembly 320 through the sliding groove 314, and then the disassembly assembly 320 is rotated forward to make the head and tail of the silo 330 contact each other; the head of the silo 330 refers to the end with the rack, and the tail refers to the end without the rack. A number of magnetic blocks are provided at the contacting places of the ends of the silo 330, and the magnetic blocks can firmly adsorb the silo 330 together to prevent the expansion of the connecting seam 334.

[0037] The cam 326 is a substantially parallel pair of engagement members 327, 328 and 329, which are coupled to the first and second end portions of the cam 326. The cam 326 is coupled to the second and second end portions of the cam 326. The cam 326 is coupled to the second and second end portions of the cam 326.

[0038] Both ends of the adjusting shaft 321 are provided with joints for matching adjusting tools such as screwdrivers and plates for easy operation. The adjusting shaft 321 serves as a longitudinal support for the fixing ring 310. A supporting roller (not shown in the figure) is also provided in the middle of the two fixing rings 310. The supporting roller is used to support and fix the two fixing rings 310. When the adjusting shaft 321 is rotated, the adjusting shaft 321 drives the adjusting gear 325, and the adjusting gear 325 drives the rack to control the silo 330. When replacing the silo 330, it is only necessary to rotate any end of the adjusting shaft 321 to make the head and tail of the silo 330 contact each other. When disassembling, it is necessary to press the adjusting shaft 321 from the end away from the driving member 106 to disengage the adjusting key 322 on the adjusting shaft 321 from the ratchet. At this time, reverse rotation is used to separate the head and tail of the silo 330, so that the head can be passed through The silo 330 is pulled out through the disassembly and assembly slot 311, and then the tail of the new silo 330 is inserted through the disassembly and assembly slot 311, and then the rack at the head is meshed with the gear, and then the adjusting shaft 321 is rotated forward. When the adjusting key 322 coincides with the opening on the ratchet, the spring pushes the limit plug 327, and the adjusting key 322 is inserted into the opening on the ratchet. Then, the adjusting shaft 321 is continuously rotated forward to make the head and tail of the silo 330 contact each other. After contact, the ratchet is restricted by the pawl 324 and cannot rotate in the opposite direction. At this time, the silo 330 is fixed on the two fixing rings 310; the limiting sleeve 326 is used to ensure the accurate position of the spring; the opening on the limiting ratchet 323 does not penetrate the limiting ratchet 323, so that the contact between the adjusting key 322 and the fixing ring 310 is isolated.

[0039] Furthermore, the silo 330 is rectangular, and a plurality of seed bins 331 are provided on the outer ring surface of the silo 330. Limiting edges 332 extend from both ends of the silo 330. The limiting edges 332 are slidably connected to the limiting groove 312 and the disassembly groove 311 respectively. A rack is fixedly connected to the limiting edge 332 near the sliding groove 314. A snap-in groove 333 is provided on the limiting edge 332, and the snap-in groove 333 abuts against the limiting block 313.

[0040] The material of the silo 330 has a certain rigidity and can provide sufficient support when rolled together; it is unfolded into a rectangle, and the number of seed bins 331 on the silo 330 is customized according to specific needs. The seed bins 331 are of a trumpet-shaped structure, which is convenient for the entry and exit of seeds, reduces the phenomenon of seed jamming, and improves the quality of sowing; the limiting edge 332 of the silo 330 is adapted to the limiting groove 312, and the outer ring surface of the silo 330 is stepped with the limiting edge 332. When the silo 330 contacts the fixing ring 310, the outer ring surface of the silo 330 can form a smooth curved surface with the outer ring surface of the fixing ring 310; when installing the silo 330, when the clamping groove 333 opened on the limiting edge 332 abuts against the limiting block 313, the head of the silo 330 can be extended from the disassembly groove 311 into the limiting groove 312.

[0041] Further, the adjustment component 200 includes two adjustment supports 201, the two adjustment supports 201 are symmetrically arranged, and the two adjustment supports 201 are detachably connected to the frame 1 respectively. The adjustment support 201 is fixedly connected to the limiting ring 203 near the fixing ring 310 side. An adjustment groove 202 is opened on the adjustment support 201, and the adjustment groove 202 is communicated with the limiting ring 203. A plurality of limiting holes 204 are opened on the limiting ring 203. A limiting rod 205 is detachably connected in the limiting hole 204, and a pin hole 317 passes through the middle of the limiting rod 205. A ring shaft 316 is rotatably connected to the driving shaft 315, and the pin hole 317 is fixedly connected to the outer ring surface of the ring shaft 316.

[0042] The distance of the adjustment slot 202 opened on the adjustment support 201 is adapted to the height of the seedling tray or the substrate in the seedling tray. It is opened according to the actual commonly used seedling tray height or the commonly used substrate height in the seedling tray, so that the sowing height of the silo 330 can be quickly and accurately controlled, thereby achieving controllable sowing accuracy; when the height needs to be adjusted, the limit rod 205 is pulled out, and then the required height is raised or lowered so that the pin hole 317 and the limit hole 204 are in the same horizontal plane, and then the limit rod 205 is extended from one limit hole 204 to the pin hole 317, and then enters the opposite limit hole 204, and the height adjustment is completed at this time; the spacing of the inner annular surface is close to the outer annular surface diameter of the annular shaft 316, and the inner annular surface spacing is greater than the outer annular surface spacing of the annular shaft 316, which is used to limit the longitudinal activity space of the annular shaft 316 and improve the stability of rotation.

[0043] Furthermore, the auxiliary component 500 includes two auxiliary brackets 501 symmetrically arranged based on the silo 330, the bottom of the auxiliary bracket 501 is rotatably connected to the drive shaft 315, the middle of the auxiliary bracket 501 is detachably connected to the bracket assembly 100, and one side of the top of the auxiliary bracket 501 is rotatably connected to a guard plate 503, which is adapted to the silo 330, and the top of the auxiliary bracket 501 is rotatably connected to a cleaning roller 502, which is in contact with the top of the silo 330.

[0044] The auxiliary bracket 501 can be mechanically connected to the limit rod 205 (not shown in the figure) or mechanically connected to the limit ring 203 (not shown in the figure). The auxiliary bracket 501 is preferably detachably connected to the bracket assembly 100 (not shown in the figure) to achieve position limitation of the cleaning roller 502 and the guard plate 503. The guard plate 503 is adapted to the silo 330 to ensure that the seeds in the seed bin 331 will not leave the seed bin 331 before reaching the predetermined position; a driving gear is arranged in the auxiliary bracket 501 close to the side of the driving member 106, and the power shaft drives the driving gear, and the driving gear drives the cleaning roller 502 to rotate in the opposite direction to the silo 330. The cleaning roller 502 is used to clean the excess seeds on the silo 330 that are not in the seed bin 331, and the excess seeds are cleaned back into the feeding assembly 400 by the rotation of the cleaning roller 502.

[0045] Further, the bracket assembly 100 includes two triangular brackets 101, and the two triangular brackets 101 are detachably connected to the frame 1. A support shaft 102 is fixedly connected to the top of the two triangular brackets 101. An extension shaft 107 is rotatably connected to either end of the support shaft 102. The triangular bracket 101 close to the extension shaft 107 is detachably connected to the driving member 106. The output end of the driving member 106 is rotatably connected to the extension shaft 107 and the driving shaft 315 through a power transmission member. Two groups of symmetrically arranged rotating combination shafts 103 are rotatably connected to the support shaft 102, and a special-shaped support member 104 and a feeding support frame 105 are fixedly connected to the rotating combination shaft 103. The special-shaped support member 104 is rotatably connected to the driving shaft 315, and the feeding support frame 105 is detachably connected to the feeding assembly 400.

[0046] The inner surface of the limiting ring 203 has a certain curvature, and the curvature angle is set with the center of the support shaft 102; the end of the support shaft 102 close to the driving member 106 is rotatably connected with the extension shaft 107, and the driving member 106 drives the extension shaft 107, and the extension shaft 107 is cocentric with the support shaft 102, so that no matter how the height of the silo 330 is adjusted, normal power supply can be guaranteed; the rotating combined shaft 103 is used to provide support for the special-shaped support member 104 and the feeding support frame 105. When the height of the silo 330 is adjusted, the feeding assembly 400 is also adjusted synchronously, and the adjustment angle is controlled within a certain range, so that the feeding assembly 400 will not be unstable due to the angle.

[0047] Furthermore, the feeding assembly 400 includes a seeding bin 403, one side of which is detachably connected to the feeding support frame 105, and the other side of the seeding bin 403 is provided with an opening, from which a bin extension plate 404 extends, and both sides of the bin extension plate 404 are rotatably connected with adjusting wheels 405, and the adjusting wheels 405 are rotatably connected to the silo 330, and a supply bin 401 is detachably provided on the top of the seeding bin 403, and a vibrating member 406 is detachably connected to the side of the seeding bin 403 close to the feeding support frame 105, and a discharge port is provided on the side of the seeding bin 403 away from the vibrating member 406, and the discharge port is adapted to the silo 330.

[0048] The adjusting wheel 405 is used to adjust the distance between the bin extension plate 404 and the silo 330, so as to avoid friction between the edge of the bin extension plate 404 and the silo 330. The cleaning roller 502 can sweep the excess seeds onto the bin extension plate 404. The bin extension plate 404 has a certain slope, which can collect the excess seeds into the drill sowing bin 403. The vibration of the vibrating member 406 can make the seeds enter the seed bin 331 better, and can also make the seeds on the bin extension plate 404 fall into the drill sowing bin 403 better; the bottom part of the supply bin 401 can be extended into the opening at the top of the drill sowing bin 403, which is used to temporarily fix the supply bin 401; the drill sowing bin 403 can increase the load-bearing capacity by reinforcing the edge, so that the supply bin 401 is stably connected to the top of the drill sowing bin 403.

[0049] Furthermore, a sealing support 402 is rotatably connected to the bottom of the supply bin 401 . The sealing support 402 is composed of two pieces, and the sealing support 402 abuts against the top of the sowing bin 403 .

[0050] When there are seeds in the supply bin 401, but the supply bin 401 needs to be withdrawn from the row sowing bin 403, the sealing support 402 rotatably connected at the bottom can seal the bottom of the supply bin 401 in time, and a sea surface layer is installed on the side of the sealing support 402 close to the bottom of the supply bin 401, which is used to seal the bottom of the supply bin 401 without damaging the seeds; the sealing support 402 is connected to the bottom of the supply bin 401 by a structure similar to a hinge and a retaining spring; when the supply bin 401 is taken out of the row sowing bin 403, When the supply bin 401 is placed in the sowing bin 403, the portion of the sealing support 402 located outside the bottom opening of the supply bin 401 first contacts the edge of the top opening of the sowing bin 403. As the supply bin 401 is extended, the sealing support 402 rotates at a certain angle until the portion of the sealing support 402 located outside the bottom opening of the supply bin 401 contacts the outside of the supply bin 401. At this time, the supply bin 401 is firmly installed in the sowing bin 403.

[0051] Furthermore, the counterweight rod 340 and the adjustment shaft 321 are longitudinally symmetrical between the two fixing rings 310 .

[0052] With the middle of the fixing ring 310 as the center of the circle and the distance from the adjusting shaft 321 to the center of the circle as the radius, the counterweight rod 340 is placed at the symmetrical point with the center of the circle, at the farthest distance from the center of the circle to the adjusting shaft 321. When the silo 330 rotates at high speed, the counterweight rod 340 can balance the centrifugal force, which can make the equipment run better.
