Abstract
Description
Technical Field
[0001] This utility model belongs to the field of Epimedium cultivation technology, specifically relating to an Epimedium cultivation fertilizer spreader. Background Technology
[0002] Epimedium is one of the original plants of the traditional Chinese medicine Epimedium. Its roots, rhizomes, stems, and leaves can all be used medicinally. It has the effects of dispelling wind and dampness, tonifying the kidneys and strengthening yang, and is mainly used to treat chronic bronchitis, impotence, and seminal emission. During the cultivation of Epimedium, fertilizer needs to be applied to the planted Epimedium using a fertilizer spreader.
[0003] The existing fertilizer spreaders used for Epimedium cultivation are generally centrifugal disc fertilizer spreaders. Centrifugal disc fertilizer spreaders are a common type of agricultural fertilization machinery, mainly composed of fertilizer tank, fertilizer discharge device, centrifugal disc, drive mechanism and frame. Fertilizer is discharged through the fertilizer discharge device and falls onto the high-speed rotating centrifugal disc. Under the action of centrifugal force, the fertilizer is thrown out along the tangential direction of the disc.
[0004] However, granular fertilizers may become damp and clump together during the stacking process. Existing centrifugal disc fertilizer spreaders do not have the function of breaking up clumps of fertilizer, which can easily cause blockages in the fertilizer discharge device or centrifugal disc, affecting the normal operation of fertilizer discharge.

[0015] (3) Beneficial effects
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention features a crushing mechanism. As fertilizer falls from the fertilizer bin, it is filtered through a screen. During filtration, any clumps in the fertilizer are retained on the screen. The pressure plate, which moves back and forth, then squeezes the clumps between the left or right side plates, crushing large clumps into smaller particles. These particles then fall through the filter screen and are scattered out, thus eliminating the clogging problem that clumps of fertilizer can cause.
[0018] This invention, by setting an adjustment mechanism, allows the two sliding rods at the outer ends of the first and second threaded rods to move relative to each other when the rotating handle is turned. This, in turn, causes the two stops on the inner side of the rectangular frame to move relative to each other, thereby changing the distance between the two stops and thus changing the area blocked by the stops at the bottom of the fertilizer box. This allows the feeding rate of the fertilizer box to be adjusted as needed. Attached Figure Description

[0027] This specific embodiment is a fertilizer spreader for Epimedium cultivation, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the device includes a fertilizer bin 1, a fixed frame 2 fixedly connected to the outside of the fertilizer bin 1, and a fertilizer spreading mechanism connected to the lower end of the fertilizer bin 1. The fertilizer spreading mechanism includes a first fixed frame 301 welded to the lower end of the fixed frame 2, a first motor 302 installed on the inner side of the first fixed frame 301, and a spreading disc 303 fixedly connected to the upper end of the output shaft of the first motor 302. A throwing plate 304 is welded to the upper side of the spreading disc 303. When the first motor 302 is started and its output shaft rotates, driving the spreading disc 303 to rotate, the fertilizer at the bottom of the fertilizer bin 1 falls onto the high-speed rotating spreading disc 303. Under the action of centrifugal force, the fertilizer is thrown out along the tangential direction of the disc, completing the fertilization of Epimedium.
[0028] Cooperate Figure 3The fertilizer box 1 is provided with an adjustment mechanism at its lower end. The adjustment mechanism includes a rectangular frame 501 fixedly connected to the lower side of the fertilizer box 1. The left and right ends of the inner side of the rectangular frame 501 are connected to the stop blocks 502. The rear side of the stop blocks 502 is fixedly connected to the limit block 503. The front end of the stop block 502 near the center of the rectangular frame 501 is fixedly connected to the sliding rod 504. The front and rear ends of the inner side of the rectangular frame 501 are provided with sliding grooves. The outer side of the limit block 503 is slidably connected to the inner side of the sliding groove at the rear end of the inner side of the rectangular frame 501. The outer side of the rear end of the sliding rod 504 is slidably connected to the inner side of the sliding groove at the front end of the inner side of the rectangular frame 501. The front and rear sides of the stop block 502 are slidably connected to the front and rear ends of the inner side of the rectangular frame 501. The upper side of the stop block 502 is slidably connected to the lower side of the fertilizer box 1. A left fixing plate 505 is fixedly connected to the front left end of the rectangular frame 501. A second bearing 506 is installed inside the left fixing plate 505. A first threaded rod 507 is fixedly connected to the inner side of the second bearing 506. A second threaded rod 508 is fixedly connected to the right end of the first threaded rod 507. A rotating handle 509 is fixedly connected to the right end of the second threaded rod 508. A right fixing plate 510 is fixedly connected to the front right end of the rectangular frame 501. A through-hole is formed inside the right fixing plate 510. The moving rod 504 has a through-hole. The outer right end of the second threaded rod 508 is rotatably connected to the inner side of the rotating hole. The threads on the outer sides of the first threaded rod 507 and the second threaded rod 508 are opposite in direction. The threaded hole inside the sliding rod 504 on the front side of the stop block 502 at the left end of the rectangular frame 501 is threadedly connected to the outer side of the first threaded rod 507. The threaded hole inside the sliding rod 504 on the front side of the stop block 502 at the right end of the rectangular frame 501 is threadedly connected to the outer side of the second threaded rod 508. When the rotating handle 509 is rotated, causing the second threaded rod 508 and the first threaded rod 507 to rotate together, the two sliding rods 504 at the outer ends of the first threaded rod 507 and the second threaded rod 508 can be moved relative to each other. At the same time, the two stops 502 on the inner side of the rectangular frame 501 will be moved relative to each other, thereby changing the distance between the two stops 502. This changes the area blocked by the stops 502 at the lower end of the fertilizer box 1, allowing the feeding rate of the fertilizer box 1 to be adjusted as needed.
[0029] Cooperate Figure 4 and Figure 5The fertilizer box 1 is equipped with a crushing mechanism, which includes a circular plate 401 fixedly connected to the inside of the fertilizer box 1. A filter screen 402 is fixedly connected inside the circular plate 401. An inclined plate 403 is fixedly connected to the upper side of the circular plate 401 at the front and rear ends of the filter screen 402. A left side plate 404 is fixedly connected to the upper left end of the circular plate 401. A first bearing 405 is installed in the middle of the interior of the left side plate 404. A reciprocating screw 406 is fixedly connected to the inner side of the first bearing 405. A right side plate 407 is fixedly connected to the upper right end of the circular plate 401. A circular hole that runs through the left and right sides is opened in the middle of the interior of the right side plate 407. The outer side of the right end of the reciprocating screw 406 is rotatably connected to the inner side of the circular hole. The left end of the output shaft of the second motor 410 is fixedly connected to the right end of the reciprocating screw 406. A pressure plate 408 is installed on the outer side of the reciprocating screw 406. A second fixing frame 409 is fixedly connected to the right side of the fertilizer box 1, and a second motor 410 is installed on the inner side of the second fixing frame 409. The lower side of the pressure plate 408 is slidably connected to the upper side of the filter screen 402. When the output shaft of the second motor 410 is started and rotated, driving the reciprocating screw 406 to rotate, the pressure plate 408 at the outer end can be driven to move left and right repeatedly along the upper side of the filter screen 402. As the fertilizer in fertilizer bin 1 falls, it is filtered by filter screen 402. During the filtration process, if there are clumps in the fertilizer, they will be retained on filter screen 402. At this time, the pressure plate 408, which moves left and right repeatedly, will squeeze the clumps of fertilizer between the left side plate 404 and pressure plate 408 or between the right side plate 407 and pressure plate 408, crushing the large clumps of fertilizer into small granules. These granules fall through the filter holes of filter screen 402 and are then scattered out, thus eliminating the clogging problem that may be caused by clumps of fertilizer.
[0030] Working principle: When fertilizing the epimedium cultivation area, first pour the fertilizer into the fertilizer tank 1, then install the fertilizer spreader at the rear end of the tractor, and then drive the tractor into the epimedium cultivation area. Then, turn the rotary handle 509 to rotate the first threaded rod 507 and the second threaded rod 508, causing the two stops 502 to separate to the required distance. After the fertilizer tank 1 dispenses fertilizer at the required rate, start the first motor 302 and the second motor 410. The second motor 410 drives the pressure plate. The filter 408 moves back and forth repeatedly, squeezing the clumps of fertilizer left on the filter 402 between the left side plate 404 and the pressure plate 408 or between the right side plate 407 and the pressure plate 408, crushing the large clumps of fertilizer into small granules. The output shaft of the first motor 302 rotates, driving the spreading disc 303 to rotate. The fertilizer falling onto the spreading disc 303 is thrown out along the tangent of the disc under the action of centrifugal force. At the same time, the tractor is started to spread fertilizer all over the epimedium cultivation area.
[0031] All technical features in this embodiment can be freely combined according to actual needs.
