[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] Example 1
[0030] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a grain seeder based on anti-clogging. The grain seeder based on anti-clogging includes a main body component 1 and a cleaning component 2, which work together to clean and unclog the discharge port.
[0031] The main component 1 includes a grain seeder 11, which has a discharge port 12.
[0032] The grain seeder 11 is an agricultural machinery device whose core function is to accurately and efficiently sow grain seeds into farmland soil according to preset row spacing, plant spacing, and sowing depth. Some models can also simultaneously complete auxiliary operations such as fertilization and soil covering. The multiple discharge ports 12 configured on this seeder are the core functional channels for transporting seeds from the equipment's storage chamber to the farmland soil. They can precisely control the amount of seeds discharged and the seed placement position, ensuring the uniformity and accuracy of the sowing operation, and effectively improving the efficiency of grain sowing and the level of planting standardization.
[0033] This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand its working principle.
[0034] The cleaning component 2 consists of four sets, all of which are installed on the inner wall of the discharge port 12. Each cleaning component 21 includes a scraper 211 installed on the inner wall of the discharge port 12. Connecting blocks 212 are hinged to both sides of the scraper 211. An extrusion rod 213 is fixed to one end of the scraper 211. An extrusion disc 214 is sleeved on the outside of the extrusion rod 213. A moving rod 215 is fixed to the bottom of the extrusion disc 214. The moving rod 215 is inserted into the inner wall of the connecting block 212 and moves.
[0035] There are two extrusion discs 214, both of which are sleeved on the upper and lower ends of the extrusion rod 213. In the initial state, the bottom extrusion disc 214 extrudes the extrusion rod 213, while the scraper 211 is in contact with the connecting block 212. The initial position of the scraper 211 is outside the discharge port 12.
[0036] The displacement of the connecting block 212 can drive the moving rod 215 to move synchronously, thereby moving the extrusion disc 214, extrusion rod 213 and scraper 211 as a whole to the bottom position of the discharge port 12. By controlling the connecting block 212 to continue to move, it can drive the extrusion rod 213 to move along the inner wall of the connecting block 212. This displacement action will drive the top extrusion disc 214 to form an axial extrusion on the extrusion rod 213, causing the extrusion rod 213 to move downward and pull one end of the scraper 211 to lift up until the scraper 211 is tightly attached to the inner wall of the discharge port 12. At this time, driving the connecting block 212 to move again can drive the scraper 211 to slide along the inner wall of the discharge port 12, effectively scraping off the soil residue attached to the inner wall of the discharge port 12. This can not only effectively prevent the grain seeds from clogging at the discharge port 12, but also achieve the cleaning and maintenance of the inner wall of the discharge port 12.
[0037] Example 2
[0038] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0039] Specifically, the cleaning component 2 also includes a connector 22, which includes a fixing rod 221 that is inserted into the inner wall of the connecting block 212.
[0040] The inner wall of the connecting block 212 has a through groove. The movement of the fixing rod 221 will drive the fixing block 222 to move. The movement of the fixing block 222 will drive the connecting block 212 to the inner wall of the discharge port 12.
[0041] Specifically, two fixing blocks 222 are sleeved on the outside of the fixing rod 221, and a cylinder 223 is connected to one end of the fixing rod 221.
[0042] The cylinder 223 will drive the fixed rod 221 to move.
[0043] The inner wall of the connecting block 212 is provided with a through groove that matches the adaptive structure. By driving the fixed rod 221 to move along a preset direction, the fixed block 222 can be driven to move synchronously. With the help of the transmission cooperation between the fixed block 222 and the connecting block 212, the connecting block 212 is pulled to move precisely to the target position on the inner wall of the discharge port 12.
[0044] Specifically, a baffle 224 is fixed to the top of the cylinder 223, and the other end of the baffle 224 is fixed to the surface of the discharge port 12.
[0045] The baffle 224 serves as a protective component for the moving rod 215. Its core function is to limit and protect the moving rod 215, which can effectively prevent the moving rod 215 from undergoing uncontrolled autonomous displacement when the connecting block 212 is located outside the outlet 12.
[0046] Specifically, a slider 225 slides on the inner wall of the fixed rod 221, and a connecting rope 226 is fixed to the top of the slider 225. One end of the connecting rope 226 is fixed to the bottom of the movable rod 215.
[0047] When the connecting block 212 moves, it drives the moving rod 215 to move. The moving rod 215 drives the connecting rope 226 to move. The moving rope 226 causes the slider 225 to slide on the inner wall of the fixed rod 221. The moving rope 226 is pulled by the moving rod 215. At this time, the moving rod 215 will drive the top extrusion plate 214 to form an axial extrusion on the extrusion rod 213, causing the extrusion rod 213 to move downward and pull one end of the scraper 211 to rise until the scraper 211 is tightly attached to the inner wall of the discharge port 12. At this time, the connecting block 212 is driven to move again, which can drive the scraper 211 to slide along the inner wall of the discharge port 12, effectively scraping away the soil residue attached to the inner wall of the discharge port 12. This can effectively prevent the grain seeds from clogging at the discharge port 12 and also achieve the cleaning and maintenance of the inner wall of the discharge port 12.
[0048] Example 3
[0049] Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0050] Specifically, the cleaning component 2 also includes a support 23, which includes a sliding sleeve 231 fixed to both ends of the connecting block 212. A threaded rod 232 is inserted into the inner wall of the sliding sleeve 231, and the sliding sleeve 231 is threadedly connected to the threaded rod 232.
[0051] The sliding sleeve 231 supports the connecting block 212, and the threaded rod 232 supports the sliding sleeve 231. Movement of the connecting block 212 causes the sliding sleeve 231 to move, which in turn moves the threaded rod 232. The movement of the threaded rod 232 causes the gear 233 to move until it meshes with the rack 234. At this point, the gear 233 rotates, causing the threaded rod 232 to rotate. The rotation of the threaded rod 232 causes the sliding sleeve 231 to slide outside the threaded rod 232. Movement of the sliding sleeve 231 then moves the connecting block 212 to the inner wall of the discharge port 12. When the connecting block 212 moves to the bottom through groove and fits against the fixed rod 221, the connecting rope 226 is pulled by the moving rod 215. The movement of the moving rod 215 will drive the top extrusion plate 214 to axially compress the extrusion rod 213, causing the extrusion rod 213 to move downward and pull one end of the scraper 211 to rise until the scraper 211 fits tightly against the inner wall of the discharge port 12. At this time, the connecting block 212 is driven to move again, which can drive the scraper 211 to slide along the inner wall of the discharge port 12, effectively scraping away the soil residue attached to the inner wall of the discharge port 12.
[0052] Specifically, a gear 233 is fixed to the bottom of the threaded rod 232, a rack 234 meshes with one side of the gear 233, and one end of the rack 234 is fixed to one end of the fixing block 222.
[0053] The movement of the fixed rod 221 causes the fixed block 222 to move. The movement of the fixed block 222 will synchronously drive the rack 234 to move and mesh with the gear 233, causing the gear 233 to rotate.
[0054] Specifically, the inner wall of the moving rod 215 is provided with a slot 215-1, the inner wall of the slot 215-1 is provided with a block 235, the inner wall of the block 235 is provided with a pressing groove 235-1, the inner wall of the pressing groove 235-1 is provided with a pressing strip 236, and the pressing strip 236 slides on the inner wall of the connecting block 212.
[0055] An elastic ring is fixed to one end of the locking block 235, and the other end of the elastic ring is fixed to the inner wall of the moving rod 215.
[0056] When the moving rod 215 moves, it continuously presses against the locking block 235 and drives the locking groove 215-1 to move. When the moving rod 215 moves the locking groove 215-1 to one side of the locking block 235, the locking block 235 will be engaged with the locking groove 215-1 by the rebound force of the elastic ring, thereby limiting the moving rod 215. At this time, the scraper 211 is already in contact with the inner wall of the discharge port 12. Then, the cylinder 223 drives the fixed rod 221 to return to its original position. The movement of the fixed rod 221 drives the rack 234 to move, and the rack 234 causes the gear 233 to rotate in the opposite direction. At this time, the screw... The reverse rotation of the groove rod 232 drives the connecting block 212 to move. The movement of the connecting block 212 will drive the scraper 211 to scrape the soil on the inner wall of the discharge port 12. When the connecting block 212 moves and causes the top of the through groove to fit with the fixed rod 221, the extrusion strip 236 will fit with the fixed rod 221 first. The extrusion strip 236 will be squeezed and move to squeeze the extrusion groove 235-1, causing the locking block 235 to move and squeeze the elastic ring. At this time, the locking block 235 will separate from the locking groove 215-1, and the scraper 211 will return to its original position due to its own gravity. At this time, the moving rod 215 will also return to its original position.
[0057] Specifically, a telescopic rod 237 is sleeved on the outside of the threaded rod 232.
[0058] The telescopic rod 237 serves as a support component for the connecting block 212, and it is rotatably connected to the threaded rod 232 via a bearing. When the connecting block 212 is displaced, the telescopic rod 237 can be driven to slide axially along the inner wall of the fixed sleeve 228, thereby providing stable support and guidance for the displacement of the connecting block 212.
[0059] Specifically, a fixing sleeve 228 is fitted on the outer side of the telescopic rod 237, and one end of the fixing sleeve 228 is fixed to one end of the cylinder 223.
[0060] The fixing sleeve 228 is used to support the telescopic pole 237.
[0061] When the grain seeder 11 has finished working and needs to turn over on the soil to switch to the next site for sowing, the grain seeder 11 will not work to feed the soil through the discharge port 12. During the turning or sowing process, soil may splash onto the inner wall of the discharge port 12.
[0062] When the grain planter 11 is not in operation, the drive cylinder 223 actuates, causing the fixed rod 221 to move in a preset direction. Simultaneously, the fixed rod 221 pulls the two fixed blocks 222 on its outer side. Through the transmission between the fixed blocks 222 and the connecting block 212, and the guiding effect of the through groove on the inner wall of the connecting block 212, the connecting block 212 is precisely moved to the target position on the inner wall of the discharge port 12. During the displacement of the fixed blocks 222, the rack 234 moves synchronously. The rack 234 meshes with the gear 233 at the bottom of the threaded rod 232, driving the gear 233 to rotate and causing the threaded rod 232 to rotate synchronously. The threaded rod 232 is threadedly engaged with the sliding sleeve 231, and its rotation drives the sliding sleeve 231 to slide axially along the threaded rod 232. The sliding sleeve 231 further pulls the connecting block 212. The connecting block 212 moves stably to the inner wall of the discharge port 12. At the same time, the displacement of the connecting block 212 drives the telescopic rod 237 to slide axially along the inner wall of the fixed sleeve 228, providing stable support and guidance for the connecting block 212. During the displacement of the connecting block 212, the moving rod 215 is driven to move synchronously. The moving rod 215 drives the extrusion plate 214, extrusion rod 213 and scraper 211 to move as a whole to the bottom of the discharge port 12. At the same time, the moving rod 215 pulls the connecting rope 226, causing the slider 225 to slide along the inner wall of the fixed rod 221. During the displacement of the moving rod 215, the locking block 235 is continuously squeezed and the slot 215-1 is moved. When the slot 215-1 moves to one side of the locking block 235, the locking block 235 engages with the slot 215-1 with the help of the rebound force of the elastic ring, thereby limiting the movement of the moving rod 215.
[0063] During this process, the moving rod 215 drives the top extrusion plate 214 to axially extrude the extrusion rod 213, causing the extrusion rod 213 to move downwards and pull one end of the scraper 211 to rise until the scraper 211 is tightly fitted with the inner wall of the discharge port 12. The drive cylinder 223 drives the fixed rod 221 to reset. The displacement of the fixed rod 221 drives the rack 234 to move. The rack 234 drives the gear 233 to rotate in the opposite direction, which in turn drives the threaded rod 232 to rotate in the opposite direction. The reverse rotation of the threaded rod 232 drives the sliding sleeve 231 to slide, pulling the connecting block 212 to move. 12 drives the scraper 211 to slide along the inner wall of the discharge port 12, efficiently scraping away the soil residue attached to the inner wall. When the connecting block 212 moves to the top of its through groove and fits against the fixed rod 221, the extrusion strip 236 first contacts the fixed rod 221 and is extruded. The displacement of the extrusion strip 236 extrudes the extrusion groove 235-1, causing the locking block 235 to compress the elastic ring and separate from the locking groove 215-1, releasing the limitation on the moving rod 215. The scraper 211 returns to its initial position under its own gravity, and the moving rod 215 resets synchronously, completing one discharge port cleaning cycle.
[0064] Precisely match the non-operational window period for cleaning when the seeder turns and switches sites, and remove the soil splashed on the inner wall of the discharge port 12 in advance to avoid seed blockage during subsequent sowing, ensuring continuous operation and eliminating the need for additional manual cleaning and waiting time.
[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
