Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable planting, in particular to a fertilizer mixing device for fruit and vegetable planting. Background Art

[0002] During the process of agricultural fruit and vegetable planting, in order to provide the nutrients required by fruits and vegetables, improve the soil properties, enhance the soil fertility, and promote the normal growth of fruits and vegetables, fertilizers usually need to be applied to the fruit and vegetable planting soil; during the production process of fertilizers, mixing is required, that is, various fertilizer raw materials are evenly mixed to ensure the effectiveness after the fertilizers are applied. Chinese patent document CN220919068U discloses a fertilizer mixer. Through the cooperative setting of a feeding cylinder, an inner cylinder, a limiting plate, a sieve mesh, a telescopic device, a first circular protrusion, a driving part, and a second circular protrusion, when the motor works, the stirring paddle and the driving part will be driven to rotate by the stirring shaft. The second circular protrusion on the driving part intermittently contacts the first circular protrusion in sequence, causing the limiting plate to rise, and then descending under the restoring action of the telescopic device, repeating in a cycle. Different types of fertilizers fall into the box body in a vibrating manner on each sieve mesh, and the stirring paddle stirs and mixes the fertilizers falling into the box body, feeding and stirring at the same time, with good mixing effect and high efficiency; at the same time, through the setting of an upper sieve mesh, a lower sieve mesh, an annular guiding groove, an annular sliding block, a worm gear, a worm, and a manhole, when a hand reaches into the box body through the manhole, the worm can be rotated. The worm drives the lower sieve mesh to rotate coaxially relative to the upper sieve mesh through the worm gear, changing the size of the mesh holes and the feeding speed, thereby adjusting the mixing ratio of various fertilizers. However, when this fertilizer mixer mixes fertilizers, only the rotation of the stirring paddle is used to mix the fertilizer raw materials. The fertilizer raw materials are easily directly dropped to the bottom of the box body under the action of gravity and then accumulate at the bottom of the box body, resulting in the inability to evenly mix the fertilizer raw materials in the box body and affecting the effectiveness of the fertilizers; at the same time, the fertilizers deposited at the bottom of the box body and adhered to the inner wall of the box cavity are difficult to clean, increasing the time-consuming of the post-treatment of the mixed fertilizers and affecting the subsequent fertilizer mixing. Content of the Utility Model

[0003] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a fertilizer mixing device for fruit and vegetable planting, which can effectively avoid the sinking of fertilizer raw materials and adhesion to the inner wall of the mixing cavity during the mixing process of fertilizer raw materials, thereby improving the uniformity of fertilizer mixing and avoiding problems such as difficulty in cleaning the mixed fertilizers.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A fertilizer mixing device for fruit and vegetable planting, comprising a fixing plate, a positioning plate, support columns, corrugated pipes, a mixing tank and a stirring assembly.

[0010] Based on further optimization of the above solution, the rotating shaft and the threaded rod are driven through a gear assembly arranged between the fixing plate and the positioning plate. The gear assembly includes an incomplete gear, a transmission gear, a gear rod, an internal gear ring, an intermediate gear and a driven gear. The incomplete gear is fixedly sleeved on the outer wall of the rotating shaft at the upper end of the threaded rod. The transmission gear is arranged on one side of the incomplete gear, and the transmission gear can be meshed with the tooth section of the incomplete gear.

A limiting ring 610 is fixedly arranged on the outer wall of the bottom end of the threaded rod 62 where the rotating shaft 61 is located, and the outer diameter of the limiting ring 610 is larger than that of the slider 63, which is used to form a hard limit for the downward sliding of the slider 63 (at the same time, a limiting ring can also be arranged on the upper outer wall of the threaded section of the threaded rod 62 to form a hard limit for the upward movement of the slider 63). An arc-shaped scraper 65 is arranged on the outer wall of the lower side of the threaded rod 62 where the rotating shaft 61 is located through a plurality of groups of stirring rods 66 (in this embodiment, four columns are arranged along the axis direction of the rotating shaft 61, and six stirring rods 66 are evenly distributed in each column) and the outer wall of the arc-shaped scraper 65 is in contact with the inner wall of the mixing tank 50. The bottom outer wall of the rotating shaft 61 is connected to the inner wall of the corresponding arc-shaped scraper 65 through a lifting plate 67; the width of the lifting plate 67 is larger than that of the stirring rod 66.

Two stirring rods 66 in the same column correspond to one group of arc-shaped scrapers 65).

[0026] Embodiment 2:

[0027] As a further optimization of the solution of the present utility model, on the basis of the solution of Embodiment 1, the rotating shaft 61 is driven to rotate by a motor 21 fixedly arranged on the positioning plate 20; at the same time, in order to facilitate feeding, a feeding pipe 22 is uniformly arranged on the outer circle of the motor 21, and the lower end of the feeding pipe 22 sequentially penetrates through the positioning plate 20 and the fixing plate 10 and is located inside the inner circle of the corrugated pipe 40.

[0028] Working principle:

[0029] In use, fertilizer raw materials are added into the mixing tank 50 through the feed pipe 22, and the rotation of the rotating shaft 61 is started synchronously. The rotating shaft 61 drives the transmission gear 13 to rotate reciprocally clockwise and counterclockwise through the incomplete gear 12 and the internal gear ring 15, and then drives the threaded rod 62 to rotate reciprocally clockwise and counterclockwise through the intermediate gear 16 and the driven gear 17. The slider 63 drives the mixing tank 50 to move up and down reciprocally through the connecting rod 64, and the corrugated pipe 40 completes the reciprocating movement of folding and unfolding; at the same time, the rotating shaft 61 drives the stirring rod 66 and the lifting plate 67 to rotate around its own axis (i.e., the rotating shaft 61), so as to realize the cleaning and scraping of the inner cavity wall of the mixing tank 50 by the arc-shaped scraper 65. When the bottom surface of the mixing tank 50 contacts the bottom surface of the lifting plate 67, the lifting plate 67 cleans and scrapes the bottom surface of the mixing tank 50 to prevent the raw materials from sinking and adhering; then the mixing tank 50 moves down, and the continuously rotating lifting plate 67 drives the raw materials at the bottom to turn up, so as to realize the uniform mixing of the raw materials, and so on in a cycle.

[0030] Embodiment 3:
