Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an adjustable extrusion bean seeding reel. Background Technology

[0002] Hill sowing is a common method of sowing crops in ridge planting. It effectively meets the requirements of reasonable seed distribution and uniform plant spacing in the field, while avoiding double sowing, missed sowing, and seed damage during the sowing process. However, current hill sowing machines still suffer from instability, limited adaptability to different crops, and limited versatility. When the planting pattern of a crop varies, the sowing implement or corresponding sowing components need to be changed in real time to meet the sowing needs of crops under different planting conditions. When using machine-driven ridge planting, the sowing implement or its operating components need to be adjusted and replaced in a timely manner to accommodate differences in crop plant spacing, sowing depth, and ridge height. The complexity of the hill sowing device makes the replacement process cumbersome, reducing the efficiency and adaptability of the sowing device, and increasing labor intensity and costs.

[0064] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] Reference Figures 1-28 This invention provides an adjustable extrusion bean seeding reel, comprising:

[0100] The adjusting outer plate 804 consists of an outer plate body 80401, an adjusting outer rail 80402, a second adjusting handwheel 80403, and a positioning pin 80404. The outer plate body 80401 is a circular plate with a central circular bushing. Two rectangular retaining keys are symmetrically machined radially outward on the outer circumference of one end of the bushing. The adjusting outer rail 80402 is an arc-shaped groove machined on the end face of the outer plate body with the retaining keys, which is identical to the adjusting inner rail 80302. The adjusting outer rail 80402 runs along the plate body... The key is symmetrically distributed along the radial central axis. The second adjusting handwheel 80403 is a circular plate with a circular through hole in the center.

The radial distribution of the circular holes is directly opposite the positioning pin 80404 along the axial direction.

[0102] Installation steps: The pull plate 1 is installed at the rear end of the tool (traction power device) via the traction plate 104 on it. The mounting shaft 2 is fixedly installed on the pull plate body 101 via the round rods at the ends of the left half shaft 201 and the right half shaft 203, respectively, and is fixedly connected to the pull plate body 101. The central axes of the left half shaft 201 and the right half shaft 203 are horizontally aligned. The mounting rod 20105 on the left half shaft 201 is vertically downward, and the eccentric shaft 207 is located directly below the left half shaft 201 and the right half shaft. The cavity-forming wheel 3 is loosely fitted onto the shaft body of the left half shaft 201 through the circular bushing at the center of the bottom plate of the first wheel body 301, so that the cavity-forming wheel 3 can rotate relative to the mounting shaft 2. At the same time, the central through hole of the linkage bushing 30201 of the linkage sleeve plate 302 on it is loosely fitted onto the right half shaft 2. On shaft 03, the linkage sleeve 302 on the hole-forming wheel 3 is located to the right of the adjusting plate 202. The outer side of its bottom plate is in contact with the outer side of the bottom plate of the seed chamber 502. The adjusting plate 202 and the seed chamber 502 restrict the axial movement of the hole-forming wheel 3 through the linkage sleeve 302 fixed on the hole-forming wheel 3. The sowing component 4 passes through the connecting tube 40103 on the hole-forming body 401 through the corresponding guide hole 30102 on the hole-forming wheel 3 and is loosely fitted radially inward on the square tube of the corresponding seed guide tube 30302. The push-pull rod 40102 is parallel to the seed-taking lever 30303 on the inoculation box 30301 and is located on the opposite side of the seed-taking lever 30303. The seed-taking lever 30303 passes through the linkage sleeve 302. The corresponding rectangular through-slot is inserted into the sliding groove 20202 on the adjusting plate 202. When the hole-forming wheel 3 rotates, it drives the linkage sleeve 302 and the inoculation box 30301 fixedly installed on it to rotate together. Through the seed guide tube 30302, it pushes the sowing component 4 to rotate together, and at the same time drives the push-pull rod 40102 to rotate along the sliding groove 20202. Due to the eccentric structure of the adjusting plate 202 relative to the left half shaft 201, the push-pull rod 40102 moves along the rectangular through-slot 30203 on the linkage sleeve 302 under the pushing action of the sliding groove 20202, and drives the sowing component 4 to move along the seed guide tube 30302, realizing the radial extension and retraction of the sowing component 4 relative to the hole-forming wheel 3. The opening stop installed on the hole-forming body 401 Plate 402 is loosely fitted onto the annular groove on the rod of the seed-forming body 401 and can rotate relative to the seed-forming body 401. In the initial state, it is fixed to the seed-forming body 401 under the action of a torsion spring. The opening lever 40202 on it is located on the same side as the seed-taking lever 30303 on the inoculation box 30301. When the seed-seeding assembly 4 rotates, when the opening lever 40202 contacts the push rod 504 fixed on the seed chamber 502, the push rod pushes the opening baffle 402 to rotate relative to the seed-forming body 401, and the seed outlet 40104 is opened. When the opening lever 40202 separates from the push rod 504, the opening baffle 402 rotates back to its original position relative to the seed-forming body 401 under the action of a torsion spring on the opening baffle 402, and closes the seed outlet again.The end cap 5 is loosely fitted onto the linkage sleeve 30201 through the central through hole of the cap body 501 and the central through hole of the bottom plate of the seed chamber 502. Its seed inlet is located directly above the mounting shaft 2, and the seed-taking component 503 on the seed chamber 502 is located directly below the mounting shaft 2. A set screw secures the end cap 5 to the first connecting plate 102 through the third through hole 103, fixing its position. The open end of the end cap 5 is loosely fitted onto the circumferential surface of the open end of the seed-forming wheel 3. The outer side of the bottom plate of the seed chamber 502 presses the linkage sleeve 302 against the open end face of the adjusting disc 202, restricting the axial movement of the seed-forming wheel 3. The seed-taking component 503 is aligned with the plane containing the axial symmetry center of the inoculation box 30301, so that the seeds taken out by the seed-taking component 503 can fall into the corresponding inoculation box 30301 below; the opening end of the seed box 6 body 601 faces vertically upward, and is aligned with the center of the seed inlet on the end cover 5 through the square through hole on the third connecting plate 603, and is fixedly installed on the outer side plate of the bottom plate of the end cover 5, thereby fixing the seed box 6 to the left side of the end cover 5; the first adjusting handwheel 701 on the adjuster 7 faces to the right, and the internal thread machined axially at the opening end of the adjusting sleeve 702 is turned... On the thread at the left end of the right half-shaft 203, located inside the linkage sleeve 30201, it can move axially relative to the right half-shaft. The adjuster 7 is symmetrically engaged in the annular groove machined on the circumferential surface of the small round shaft of the right pull ring body 20501 via the front push-pull plate 703. Rotating the first adjusting handwheel 701 can make the adjuster 7 move axially relative to the right half-shaft 203. The push-pull plate 703 drives the right pull ring body 20501 to move axially, and the second connecting plate 206 installed on it drives the eccentric shaft 207 to move up and down along the mounting rod 20105, thereby realizing the adjustment of the axis of the adjusting disc 202. The adjustable ground wheels 8 are respectively fitted onto the bushings of the first wheel body 301 and the linkage bushing 30201 of the linkage sleeve plate 302 through one on each side of their central holes. They are also fixedly connected through circular through holes machined on the circumference of the boss on the bottom plate of the third wheel body 80101, to the corresponding mounting holes on the outer ends of the bushings of the first wheel body 301 and the mounting holes on the linkage bushing 30201. The adjustable ground wheels 8 are thus fixedly installed at the left and right ends of the hole-forming wheel 3. The rotation of the two ground wheels drives the hole-forming wheel 3 to rotate relative to the mounting shaft 2, thereby driving the sowing component 4 to rotate and achieve the hole-forming process.

[0103] Working principle: Before operation, adjust the sowing device to adapt to the ridge height, sowing depth, and plant spacing according to the planting pattern. First, adjust the ridge height by adjusting the size of the adjustable ground wheel 8 to meet the sowing requirements at different ridge heights. Move the second adjusting handwheel 80403 outward along the axis. When the adjusting outer disc 804 is in contact with the inner side of the outer retaining ring 805, the second adjusting handwheel 80403 moves to its maximum position. At this time, the adjusting inner disc 803 and the adjusting outer disc 804 are axially symmetrically installed on both sides of the square rod of the extrusion wheel 802. Rotating the second adjusting handwheel 80403 will drive the adjusting outer disc 804 and the adjusting inner disc 803 to rotate together. By adjusting the grooves on the outer track 80402 and the inner track 80302, the connecting rod 80203 installed inside is pushed to drive the pressing plate 80201 to extend and retract radially, thereby adjusting the diameter of the adjustable ground wheel 8 and adjusting the height difference between the adjustable ground wheel 8 and the first wheel body 301 of the seeding wheel 3, thus adapting to the needs of different ridge heights for sowing. Next, the sowing depth is adjusted. By rotating the first adjusting handwheel 701, the adjuster 7 can move axially relative to the right half-shaft 203. The push-pull plate 703 drives the right push-pull ring 205 to move axially along the right half-shaft 203, and through the second connecting plate 206 and eccentric shaft 207 installed on it, the adjustment is completed. The left push-pull ring 204 moves axially along the left half-shaft 201 relative to or towards the right push-pull ring 205, thereby causing the lower hinged left and right second connecting plates 206 to drive the eccentric shaft 207 to move along the mounting rod 20105, thus changing the axis of the adjusting disc 202 and consequently changing the extension length of the sowing component 4 relative to the hole-forming wheel 3. When the eccentric shaft 207 moves upward along the mounting rod 20105, the eccentricity between the axis of the adjusting disc 202 and the center axis of the left and right half-shafts decreases, thus reducing the extension amount of the sowing component 4 relative to the hole-forming wheel 3 and decreasing the sowing depth. When the eccentric shaft 207 moves downward along the mounting rod 20105... When the eccentricity between the axis of the adjusting disc 202 and the center axis of the left and right half-axis increases, the extension of the sowing component 4 relative to the hole-forming wheel 3 increases, thereby increasing the sowing depth and completing the sowing depth adjustment. Finally, the sowing spacing is adjusted. First, the extension of the sowing component 4 relative to the hole-forming wheel 3 is adjusted by rotating the adjusting device 7 (same as the sowing depth adjustment method). Then, the height difference between the ground wheel and the first wheel body 301 of the hole-forming wheel 3 is adjusted by rotating the second adjusting handwheel 80403 (same as the ridge height adjustment method), so that the sowing component 4 enters the soil at the depth before the sowing spacing adjustment, thereby achieving the sowing spacing adjustment.When decreasing the planting spacing, first move the eccentric shaft 207 upward along the mounting rod 20105 to reduce the eccentricity between the center of the adjusting disc 202 and the center axes of the left and right half-shafts, thus reducing the extension of the sowing component 4 relative to the hole-forming wheel 3. Then, by rotating the second adjusting handwheel 80403, reduce the height difference between the adjustable ground wheel 8 and the first wheel body 301, restoring the soil penetration depth of the sowing component 4 to the depth before the planting spacing adjustment. When increasing the planting spacing, first move the eccentric shaft 207 downward along the mounting rod 20105 to increase the eccentricity between the center of the adjusting disc 202 and the center axes of the left and right half-shafts, thus increasing the extension of the sowing component 4 relative to the hole-forming wheel 3. Then, by rotating the second adjusting handwheel 80403, increase the height difference between the adjustable ground wheel 8 and the first wheel body 301, restoring the soil penetration depth of the sowing component 4 to the depth before the planting spacing adjustment, thus completing the adjustment of the planting spacing.

[0104] When the sowing device is working, the pull plate 1 drives the sowing device forward, and the two adjustable ground wheels 8 drive the hole-forming wheel 3 to rotate, which in turn drives the sowing component 4 installed on it to rotate. During the rotation of the sowing component 4, under the action of the sliding groove 20202 of the adjusting plate 202, it moves along the seed guide tube 30302 on the inoculation box 30301, and drives the extrusion body 40101 to gradually extend outward from the guide hole on the first wheel body 301. During the rotation of the hole-forming wheel 3, when the seed-picking lever 30303 on the inoculation box 30301 contacts the rotating rod 50303 on the seed-picking component 503, it pushes it to move backward. The rotating rod 50303 pushes the seed-picking component 503 to rotate, bringing the seeds in the seed-picking hole 50302 out of the seed chamber 502 and into the corresponding inoculation box 30301. During the rolling of the hole-forming wheel 3, the seeds are guided into the corresponding extrusion body 40101 through the seed guide tube 30302 at the lower end of the seed box. In cavity 101, when the seed-taking lever 30303 separates from the rotating rod 50303, the seed-taking wheel resets via the torsion springs installed at both ends, and the seed-taking hole on it rotates back into the seed chamber 502 to take seeds. The extrusion body 40101 gradually enters the soil to form a seed hole as the hole-forming wheel 3 rotates. When it reaches its maximum depth, the opening lever 40202 contacts the push rod 504 installed on the seed chamber 502. Under its pushing action, it can rotate relative to the extrusion body 40101, opening the seed outlet 40104. The seeds inside fall into the seed hole as the extrusion body 40101 rotates. As the hole-forming wheel 3 continues to rotate, the extrusion body 40101 rotates out of the soil and gradually retracts into the hole-forming wheel. When the opening lever 40202 separates from the push rod 504, under the action of the torsion spring installed on the opening baffle 402, the opening baffle rotates relative to the extrusion body to reset, closing the seed outlet again, completing one hole-forming and sowing process.
