Abstract
Description
Technical Field
[0001] This utility model relates to the field of planting equipment technology, specifically a crop planting displacement planter. Background Technology
[0002] Crop seeding device (or seed metering device) is a key component of agricultural seeding machinery. It is mainly used to accurately sow seeds into the soil at a set spacing, depth and quantity. The seeding device is the core component of the seeder. It controls the arrangement and sowing of seeds through mechanical, airflow or electronic means to ensure that crops are evenly distributed in the field and achieve efficient and precise sowing operations.
[0003] However, most existing mass-produced planters use an intermittent structure to disperse seeds, and do not accurately weigh the number of seeds. This results in uneven seed weight in the seed pits during subsequent sowing, leading to inconsistent plant numbers and making subsequent management difficult. Furthermore, existing mass-produced planters do not have seed balance monitoring devices in their seed storage boxes. When the seed quantity is insufficient, continuous operation is easily interrupted, seriously affecting sowing efficiency and planting uniformity.
[0004] Therefore, a crop planting displacement planter is needed to improve the above problems. Utility Model Content
[0005] To address the problem that the precise weighing of seeds during planting with a crop planting metering device leads to uneven seed weight in the planting pits, resulting in inconsistent plant numbers and hindering subsequent management, this invention provides a crop planting metering device to solve the aforementioned issues.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A crop planting device includes a discharge device housing. A duckbill is annularly embedded in the outer wall of the discharge device housing. A discharge assembly is provided on the side wall of the discharge device housing. A partition is provided on one side of the discharge assembly at the port of the discharge device housing. A connecting hole is provided on the outer wall of the partition. A partition block is provided on one side of the partition at the inner wall of the discharge device housing. A discharge trough is provided on the outer wall of the partition block. The duckbill is connected to the port of the discharge trough, and the connection between the discharge trough and the duckbill is a continuous structure. A baffle plate is provided on one side of the discharge trough at the inner wall of the discharge device housing.
[0008] As a preferred embodiment of this utility model, the discharge assembly includes a mounting base, which is embedded in the side wall of the discharger housing. A mounting seat is installed on the outer wall of the mounting base, and a mounting groove is formed on the outer wall of the mounting seat. A connecting pipe is installed on the inner wall of the mounting groove, and one end of the connecting pipe is connected to the outer wall of the mounting base, and the connecting pipe is located on one side of the connecting hole.
[0009] As a preferred embodiment of this utility model, a weighing sensor is embedded in the inner wall of the mounting groove, and a weighing enclosure is slidably connected above the weighing sensor and on the inner wall of the mounting groove. The weighing enclosure has a concave cross-section, and a first electrically controlled cylinder is installed on one side of the weighing enclosure and on the inner wall of the mounting groove, with one end of the first electrically controlled cylinder connected to the weighing enclosure.
[0010] As a preferred embodiment of this utility model, the weighing enclosure is located on one side of the connecting pipe, and a storage box is installed directly above the mounting groove and on the outer wall of the mounting base. A discharge sleeve is provided on the outer wall of the storage box, and a sliding groove is provided on the inner wall of the discharge sleeve. A partition plate is slidably connected to the inner wall of the sliding groove.
[0011] As a preferred embodiment of this utility model, a second electrically controlled cylinder is installed at one end of the partition plate. The second electrically controlled cylinder is installed on the outer wall of the mounting base, and a controller is provided on the inner wall between the storage box and the mounting base.
[0012] As a preferred embodiment of this utility model, a buzzer light is installed on the outer wall of the storage box, a contact sensor is provided on the inner wall of the storage box, and a feed pipe is provided on one side of the contact sensor and on the top outer wall of the storage box.
[0013] As a preferred embodiment of this utility model, a sealing plate is provided on one side of the duckbill and on the outer wall of the displacement device housing, a limit spring is provided at one end of the sealing plate, and a pressure plate is provided on one side of the limit spring and on the side wall of the sealing plate.
[0014] As a preferred embodiment of this utility model, multiple sets of connecting holes are provided and are respectively located on the outer wall of the partition, wherein the connecting holes form a ring structure. Multiple sets of partitions are provided and are respectively located on the inner wall of the discharger housing. The controller is connected to a weighing sensor, a first electric cylinder, a second electric cylinder, a buzzer, and a contact sensor via wires, and the connection method is electrical connection. Multiple sets of contact sensors are arranged from top to bottom and are respectively located on the inner wall of the storage box, wherein the weighing enclosure is located directly below the discharge sleeve.
[0015] Compared with existing technologies, this utility model enables seed weighing by setting a discharge component in the crop planting discharge device. One end of the second electric cylinder drives the partition plate to move laterally, so that the partition plate moves laterally on the inner wall of the chute, causing the seeds in the storage box to fall into the inner cavity of the weighing enclosure through the discharge sleeve. Subsequently, the weighing sensor generates data based on the weight of the seeds, and at the same time, the weighing sensor generates an electrical signal that is transmitted to the controller through wires. One end of the first electric cylinder pushes the weighing enclosure to move laterally. When the weighing enclosure moves to the connecting pipe, the seeds fall into the connecting pipe, causing the seeds in the inner cavity of the connecting pipe to move through the connecting hole to the inner cavity of the discharge device shell. This helps to solve the problem of uneven seed weight in the seed pits during subsequent sowing due to inaccurate seed quantity, which leads to inconsistent plant numbers and inconvenience in subsequent management.
[0016] This invention, by incorporating a feeding component into a crop planting metering device, enables a contact sensor to contact the seeds inside the seed storage bin. When the seed level in the bin is low, the contact sensor generates an electrical signal, which is transmitted to the controller via a wire. When the set parameters are reached, the controller activates a buzzer, causing the buzzer to emit sound and light to alert the operator to replenish seeds. This addresses the problem in existing metering planters where the seed storage bin lacks a seed level monitoring device, leading to interruptions in continuous operation when the seed level is insufficient, severely impacting sowing efficiency and planting uniformity.

[0025] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The discharge assembly 3 includes a mounting base 301, which is embedded in the side wall of the discharger housing 1. A mounting seat 302 is mounted on the outer wall of the mounting base 301. A mounting groove 303 is formed on the outer wall of the mounting seat 302. A connecting pipe 304 is mounted on the inner wall of the mounting groove 303, with one end connected to the outer wall of the mounting base 301 and located on one side of the connecting hole 5. A weighing sensor 305 is embedded in the inner wall of the mounting groove 303. A weighing enclosure 306 is slidably connected above the weighing sensor 305 and on the inner wall of the mounting groove 303. The weighing enclosure 306 has a concave cross-section. A first electrically controlled cylinder 307 is mounted on one side of the weighing enclosure 306 and on the inner wall of the mounting groove 303, with one end connected to the weighing enclosure 306. A weighing barrier 306 is located on one side of the connecting pipe 304. A storage box 308 is installed directly above the mounting groove 303 and on the outer wall of the mounting base 302. A discharge sleeve 309 is provided on the outer wall of the storage box 308. A sliding groove 310 is provided on the inner wall of the discharge sleeve 309. A partition plate 311 is slidably connected to the inner wall of the sliding groove 310. A second electric cylinder 312 is installed at one end of the partition plate 311. The second electric cylinder 312 is installed on the outer wall of the mounting base 302. A controller 313 is provided on the inner wall between the storage box 308 and the mounting base 302. A buzzer 314 is installed on the outer wall of the storage box 308. A contact sensor 315 is provided on the inner wall of the storage box 308. A feed pipe 316 is provided on one side of the contact sensor 315 and on the top outer wall of the storage box 308. The weighing barrier 306 is located directly below the discharge sleeve 309.
[0026] Based on the above structural features and connection relationships, the baffle plate 8 blocks the seeds in the inner cavity of the dispensing device housing 1, and the partition plate 4 and partition block 6 divide the inner cavity of the dispensing device housing 1 into multiple individual cavities. When the dispensing device housing 1 rotates, its discharge chute 7 is located at the bottom of the individual cavity, so that the seeds can slide into the inner cavity of the duckbill 2 through the discharge chute 7 under the action of gravity.
[0027] A sealing plate 9 is provided on one side of the duckbill 2 and on the outer wall of the displacer housing 1. A limit spring 10 is provided at one end of the sealing plate 9, and a pressure plate 11 is provided on one side of the limit spring 10 and on the side wall of the sealing plate 9. Multiple sets of connecting holes 5 are provided and are located on the outer wall of the partition 4, wherein the connecting holes 5 are in a ring structure. Multiple sets of partitions 6 are provided and are located on the inner wall of the displacer housing 1. The controller 313 is connected to the weighing sensor 305, the first electric cylinder 307, the second electric cylinder 312, the buzzer 314 and the contact sensor 315 through wires, and the connection method is electrical connection, so that the device is powered on, and then the controller 313 controls the weighing sensor 305, the first electric cylinder 307, the second electric cylinder 312, the buzzer 314 and the contact sensor 315 to be powered on and operated. Multiple sets of contact sensors 315 are arranged from top to bottom and are located on the inner wall of the storage box 308.
[0028] In this crop planting system, the seed feeder uses the feed pipe 316 to place seeds into the inner cavity of the storage bin 308 for storage. Then, the controller 313 is activated, causing it to operate the second electrically controlled cylinder 312. This cylinder 312 then moves one end of the partition plate 311 laterally, causing the partition plate 311 to move laterally along the inner wall of the slide groove 310. This allows the seeds inside the storage bin 308 to pass through the discharge sleeve 309. The seeds fall into the inner cavity of the weighing enclosure 306. Then, the weighing sensor 305 generates data based on the weight of the seeds. At the same time, the weighing sensor 305 generates an electrical signal that is transmitted to the controller 313 through a wire. When the set parameters are reached, the controller 313 will control the second electric cylinder 312 to operate, so that the second electric cylinder 312 pushes the partition plate 311 to move laterally, so that the partition plate 311 blocks the feeding sleeve 309, and the weight of the seeds is weighed before planting.
[0029] The controller 313 controls the operation of the first electrically controlled cylinder 307, causing one end of the first electrically controlled cylinder 307 to push the weighing enclosure 306 to move laterally. When the weighing enclosure 306 moves to the connecting pipe 304, the seeds fall into the connecting pipe 304. When the dispensing device housing 1 moves on the ground, it causes the dispensing device housing 1 to drive the partition 4 to rotate. When the partition 4 drives the connecting hole 5 to move to the connecting pipe 304, the seeds inside the connecting pipe 304 move through the connecting hole 5 to the dispensing device. When the outer shell 1 rotates, the pressure plate 11 will contact the ground, causing the pressure plate 11 to drive the sealing plate 9 to unfold, so that the sealing plate 9 and the duckbill 2 open, and the seeds in the inner cavity of the outer shell 1 are discharged through the discharge trough 7 and discharged through the duckbill 2 for planting. This helps to solve the problem that the number of seeds was not accurately weighed, resulting in uneven seed weight in the seed pit during subsequent sowing, which will lead to inconsistent number of subsequent plants and make subsequent management inconvenient.
[0030] When the seeds inside the storage bin 308 come into contact with the contact sensor 315, the contact sensor 315 is arranged in multiple sets from top to bottom, resulting in different contact areas between the contact sensor 315 and the seeds. When the seeds in the storage bin 308 are low, the contact sensor 315 will generate an electrical signal, which will be transmitted to the controller 313 through the wire. When the set parameters are reached, the controller 313 will then control the buzzer 314 to operate, causing the buzzer 314 to emit sound and light, thereby prompting the operator to replenish the seeds. This helps to solve the problem that existing mass planting machines do not have a seed balance monitoring device in the seed storage bin, which can easily cause continuous operation to be interrupted when the seed quantity is insufficient, seriously affecting the sowing efficiency and planting uniformity.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
