Description

Technical Field

[0001] This utility model belongs to the field of fertilizer applicator technology, specifically relating to a fixed-distance topdressing machine. Background Technology

[0002] Topdressing is a crucial management step in crop growth. For grains such as wheat, timely, appropriate, and precise application of nitrogen fertilizer is essential for ensuring high yields and quality. Currently, most farmers still use manual methods for topdressing. The specific operation involves the worker carrying a fertilizer container, walking along the crop furrows, and relying on personal experience and visual estimation to grab fertilizer by hand and scatter or spot-apply it at the desired location.

[0003] However, traditional manual fertilization methods still have the following drawbacks: the location of fertilization points depends entirely on the worker's subjective judgment and walking speed, resulting in a high degree of randomness and making precise, fixed-distance fertilization impossible. This directly leads to a chaotic distribution of fertilization points and uneven fertilizer application among plants. Some plants may not be able to effectively absorb nutrients due to fertilization points being too far away, while other areas may experience waste or even seedling burn due to excessive concentration of fertilizer, severely affecting fertilizer utilization efficiency and uniform crop growth.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a fixed-distance topdressing machine that can precisely control the fertilization distance and improve fertilizer utilization efficiency.

[0006] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A fixed-distance topdressing machine includes a hopper for holding fertilizer, a distributing wheel rotatably mounted at the bottom of the hopper, and a mounting frame. The mounting frame is equipped with traveling wheels, which are connected to the distributing wheel via a transmission connection. The distributing wheel has a plurality of distributing grooves formed on its circumferential surface, arranged in a circular array around the axis of the distributing wheel. An adjusting plate is slidably mounted within each distributing groove, the top of which has an arc-shaped surface adapted to the circumferential surface of the distributing wheel. The bottom of the hopper is also provided with a mounting ring for mounting the distributing wheel. The top of the mounting ring has a feed pipe communicating with the hopper, and the bottom has a discharge pipe, the diameters of which are adapted to the openings of the distributing grooves.

[0008] Furthermore, the bottom of the adjusting plate is provided with a connecting post, and movable posts are formed on both sides of the connecting post; the bottom of the distributing trough is formed with a movable cavity that slides with the connecting post, and adjusting grooves are formed on both sides of the movable cavity for the movable posts to pass through. The movable posts facilitate the control of the raising and lowering of the adjusting plate.

[0009] Furthermore, a clamping block is movably provided at the end of the movable column, and a cavity is formed at the end of the movable column. A plug-in post is formed on the inner side of the clamping block, which slides into the cavity. A return spring is also installed inside the cavity. The two ends of the return spring are respectively connected to the end of the plug-in post and the bottom of the cavity. The clamping block makes the adjusting plate more stable.

[0010] Furthermore, the outlets of the feeding pipe are located on both sides of the feeding pipe, and the feeding pipe is equipped with distribution blocks. The top of the distribution blocks has a guide slope facing the outlet of the feeding pipe, and the sides of the feeding pipe are also inclined with guide plates. The distribution blocks allow fertilizer to fall from both sides, improving the efficiency of fertilization.

[0011] Furthermore, a first synchronous pulley is fixedly sleeved on the axle of the traveling wheel, and a second synchronous pulley is fixedly installed on one side of the distributing wheel. A synchronous belt is sleeved on both the first and second synchronous pulleys. The synchronous belt facilitates the rotation of the distributing wheel.

[0012] Furthermore, the mounting frame is also equipped with a handle. The handle facilitates the movement of the entire fertilizer applicator.

[0013] With the above structure, the fixed-distance topdressing machine of this utility model, compared with the prior art, sets a material distribution wheel under the hopper. The material distribution wheel is provided with several material distribution grooves in a circular array. The rotation of the walking wheel drives the rotation of the material distribution wheel. The rotation of the walking wheel can accurately control the spacing of the fertilizer application. In addition, by moving the height of the adjustment plate, not only the spacing of the fertilizer application can be adjusted, but also the amount of fertilizer can be controlled.

Detailed Implementation

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0024] like Figures 1 to 7As shown, this utility model relates to a fixed-distance topdressing machine, which includes a hopper 1 for holding fertilizer, a distributing wheel 2 rotatably mounted at the bottom of the hopper 1, and a mounting frame 3. A traveling wheel 31 is mounted on the mounting frame 3, and the traveling wheel 31 is connected to the distributing wheel 2 via a transmission connection. The traveling wheel 31 drives the distributing wheel 2 to rotate, with the traveling wheel 31 positioned closer to the front and the hopper 1 closer to the rear. Additionally, a handle 32 is provided on the mounting frame 3, positioned closer to the rear for easy gripping by the operator. Several distributing grooves 21 are formed on the circumferential surface of the distributing wheel 2, and these grooves are connected to the distributing wheel 2. The axis is arranged in a circular array around the center line. The number of material distribution wheels 2 is even and greater than two. An adjusting plate 4 is slidably installed in the material distribution groove 21. The top of the adjusting plate 4 has an arc-shaped surface 45 that matches the circumferential surface of the material distribution wheel 2. The bottom of the hopper 1 is also provided with an mounting ring 11 for mounting the material distribution wheel 2. The mounting ring 11 rotates with the circumferential surface of the material distribution wheel 2. The top of the mounting ring 11 forms a feed pipe 111 that communicates with the hopper 1, and the bottom forms a discharge pipe 112. The diameters of the feed pipe 111 and the discharge pipe 112 are matched with the opening of the material distribution groove 21. Specifically, a first synchronous wheel 311 is fixedly mounted on the shaft of the walking wheel 31, and a second synchronous wheel 22 is fixedly mounted on one side of the distribution wheel 2. A synchronous belt 5 is mounted on the first synchronous wheel 311 and the second synchronous wheel. The distribution wheel 2 can be rotated by the synchronous belt 5. In this way, the fertilization spacing is not controlled by time, but by the number of rotations of the walking wheel 31. That is, the fertilization spacing is fixed regardless of whether the walking is fast or slow. When it is necessary to adjust the fertilization spacing, the adjusting plate 4 can be adjusted upwards at intervals so that the arc surface 45 of the adjusting plate 4 is flush with the circumferential surface of the distribution wheel 2, thus blocking the distribution groove 21. The fertilization spacing can be adjusted. In addition, the height of the adjusting plate 4 can also be adjusted to adjust the amount of fertilizer.

[0025] In this embodiment, the bottom of the adjusting plate 4 is provided with a connecting post 41, and movable posts 42 are formed on both sides of the connecting post 41; the bottom of the distributing trough 21 is formed with a movable cavity 211 that slides with the connecting post 41, and the sides of the movable cavity 211 are formed with adjusting grooves 212 for the movable post 42 to pass through. A clamping block 43 is also movably provided at the end of the movable post 42, and a cavity 421 is formed at the end of the movable post 42. A plug-in post 431 that slides with the cavity 421 is formed on the inner side of the clamping block 43; a return spring 44 is also installed in the cavity 421. The two ends of the return spring 44 are respectively connected to the end of the plug-in post 431 and the bottom of the cavity 421. When adjustment is required, the clamping blocks 43 can be pulled to both sides to separate them from the side wall of the distributing wheel 2. Adjustment can then begin by moving them up and down. In addition, to control the accuracy of adjustment, scale lines can be set on the outside of the adjustment groove 212. After adjustment, the clamping blocks 43 can be released, and the clamping blocks 43 can be pulled together and clamped on the side wall of the distributing wheel 2 under the action of the return spring 44. Anti-slip pads can be set on the inside of the clamping blocks 43 to increase friction and improve the clamping effect.

[0026] In this embodiment, the outlets of the feeding pipe 112 are located on both sides of the feeding pipe 112. A distribution block 113 is provided inside the feeding pipe 112, and the top of the distribution block 113 has a guide slope facing the outlet of the feeding pipe 112. Guide plates 114 are also inclinedly provided on both sides of the feeding pipe 112. The distribution block 113 allows fertilizer to fall from both sides, improving fertilization efficiency.

[0027] The method of using this utility model is as follows: First, adjust the position of the adjusting plate 4 according to the spacing requirements of fertilization. Then, pour fertilizer into the hopper 1. Then, you can push the topdressing machine to move by the handle 32. During the movement, the walking wheel 31 drives the distributing wheel 2 to rotate, so that the fertilizer can be spread out at equal intervals.

[0028] The above provides a detailed description of the fixed-distance topdressing machine provided by this utility model. The specific embodiments are only used to help understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
