Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, and in particular to a quantitative fertilization device. Background Technology

[0002] In agricultural planting, in order to complete fertilization quickly and evenly, improve fertilization efficiency, and avoid excessive application of fertilizer and reduce fertilizer residue in the soil, quantitative underground fertilizer applicators are used to apply fertilizer in a quantitative manner.

[0003] Currently, existing quantitative underground fertilizer applicators require operators to hold the top T-shaped handle with both hands and press it to insert the perforated tip at the bottom of the applicator into the soil for fertilization. Due to the large differences in root distribution depth among different crops, and the fact that operators tend to rely on experience to control the pressing distance of the T-shaped handle during fertilization, the perforated tip is easily inserted too deeply or too shallowly. If inserted too deeply, the fertilizer is difficult for the roots to reach and absorb, resulting in nutrient waste. If inserted too shallowly, the fertilizer is easily volatilized or washed away by rainwater, reducing fertilizer utilization. Therefore, we propose a quantitative fertilization device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative fertilization device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quantitative fertilization device includes a fertilization tube with a T-shaped handle inserted at its top. The side of the T-shaped handle is fixedly connected to the upper side of the fertilization tube via a return spring. A connecting block is fixedly connected to the side of the fertilization tube, and an insertion rod is vertically inserted inside the connecting block. A limiting plate is provided above the insertion rod. A rectangular groove is formed inside the connecting block, and a rectangular block is inserted inside the rectangular groove. A threaded groove is formed inside the rectangular block, and a threaded rod is inserted inside the threaded groove. The threaded rod is horizontally inserted inside the connecting block via a bearing. A rotating block is fixedly connected to the end of the threaded rod. The insertion rod has slots that are equidistant from top to bottom that are adapted to the rectangular block.

[0006] Preferably, the upper and lower ends of the rectangular block are symmetrically connected with linkage blocks, and a guide rod is inserted horizontally inside the linkage block, with one end of the guide rod fixedly connected to the inner wall of the rectangular groove.

[0007] Preferably, there are two sets of connecting blocks and insertion rods, and the two sets of connecting blocks and insertion rods are symmetrically distributed about the central axis of the limiting plate.

[0008] Preferably, a rubber plate is glued to the top of the limiting plate, and the longitudinal section of the rubber plate is set as a U-shaped structure.

[0009] Preferably, the bottom end of the limiting plate is symmetrically connected with a connecting sleeve, the top end of the insertion rod is inserted into the inside of the connecting sleeve, and the side of the connecting sleeve is connected to the insertion rod through a T-shaped rod.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A quantitative fertilization device includes a fertilizer tube 1, with a T-shaped handle 2 inserted at the top of the fertilizer tube 1. The side of the T-shaped handle 2 is fixedly connected to the upper side of the fertilizer tube 1 via a return spring 3. The return spring 3 allows the T-shaped handle 2 to automatically return to its original position when pressure is lost, thus improving the ease of use of the device. The specific quantitative fertilization principle of the fertilizer tube 1 and the T-shaped handle 2 is existing technology and will not be described in detail here. A connecting block 4 is fixedly connected to the side of the fertilizer tube 1, and an insertion rod 5 is vertically inserted inside the connecting block 4. A limiting device is provided above the insertion rod 5. The mounting plate 6 and the connecting block 4 have a rectangular groove 7 inside, and a rectangular block 8 is inserted inside the rectangular groove 7. The rectangular block 8 has a threaded groove inside, and a threaded rod 9 is inserted inside the threaded groove. The threaded rod 9 is inserted laterally inside the connecting block 4 through a bearing. The outer surface of the threaded rod 9 has an external thread (not shown in the figure). Through the threaded engagement between the threaded rod 9 and the rectangular block 8, the rectangular block 8 can be driven to move laterally inside the rectangular groove 7. The end of the threaded rod 9 is fixedly connected to a rotating block 10. The insert rod 5 has slots that are equidistant from top to bottom to match the rectangular block 8.

[0017] Furthermore, refer to Figure 4 It can be seen that the upper and lower ends of the rectangular block 8 are symmetrically connected with linkage blocks 11, and a guide rod 12 is inserted horizontally inside the linkage block 11. One end of the guide rod 12 is fixedly connected to the inner wall of the rectangular groove 7. When the operator rotates the rotating block 10, the rectangular block 8 can be driven to move horizontally inside the rectangular groove 7 under force, and the linkage block 11 connected to the rectangular block 8 can slide along the outer surface of the guide rod 12 under force, thereby realizing the horizontal guidance of the linkage block 11 to ensure the stable horizontal movement of the rectangular block 8.

[0018] Furthermore, refer to Figure 2 and Figure 3 It can be seen that there are two sets of connecting blocks 4 and insertion rods 5, and the two sets of connecting blocks 4 and insertion rods 5 are symmetrically distributed about the central axis of the limiting plate 6. During use, the support effect of the limiting plate 6 can be guaranteed by the cooperation of the two sets of connecting blocks 4 and insertion rods 5.

[0019] Furthermore, refer to Figure 3It can be seen that a rubber plate 14 is glued on the upper part of the limiting plate 6, and the longitudinal section of the rubber plate 14 is set as a U-shaped structure. In use, the rubber plate 14 with the U-shaped structure can realize the surrounding protection of the side of the limiting plate 6, thereby effectively preventing the T-shaped handle 2 and the limiting plate 6 from hard collision.

[0020] Furthermore, refer to Figure 3 It can be seen that the bottom end of the limiting plate 6 is symmetrically connected with a connecting sleeve 13, and the top end of the insertion rod 5 is inserted into the connecting sleeve 13. The side of the connecting sleeve 13 is connected to the insertion rod 5 through a T-shaped rod 15. In use, the insertion rod 5 and the limiting plate 6 can be separated by the cooperation of the connecting sleeve 13 and the T-shaped rod 15, so that the damaged limiting plate 6 or the insertion rod 5 can be replaced.

[0021] Furthermore, refer to Figure 3 It can be seen that the outer wall of the T-shaped rod 15 is provided with external threads, the top of the insertion rod 5 is provided with a positioning groove that matches the T-shaped rod 15, and the inner wall of the positioning groove is provided with internal threads. Through the threaded engagement of the T-shaped rod 15 and the positioning groove, the limiting effect of the T-shaped rod 15 on the connecting sleeve 13 can be guaranteed.

[0022] Working principle: When using this utility model, the operator can first connect one end of the delivery hose to the interface on the side of the fertilizer pipe 1 through the clamp, and then connect the other end of the fertilizer pipe 1 to the interface of the fertilizer bucket. The operator can then determine the fertilization depth according to the type of crop. The operator can then rotate the rotating block 10 to drive the threaded rod 9 to rotate simultaneously, thereby driving the threaded rod 9 and the rectangular block 8 to engage in threaded engagement. This causes the rectangular block 8 to move laterally in the rectangular groove 7 inside the connecting block 4, and pull the rectangular block 8 out of the slot inside the insertion rod 5. When the two sets of rotating blocks 10 are rotated in sequence to release the restriction on the two sets of insertion rods 5, the operator can adjust the vertical position of the limiting plate 6, thereby controlling the downward pressing distance of the T-shaped handle 2. After adjustment, the operator can rotate the rotating block 10 in reverse order to limit the insertion rod 5 again. The worker can then carry the fertilizer bucket on their back and hold the T-shaped handle 2 to place the fertilizer tube 1 in the area where fertilizer is needed. The worker can then press down the T-shaped handle 2 to drive the perforated tip at the bottom of the fertilizer tube 1 into the soil for fertilization. When the T-shaped handle 2 comes into contact with the rubber plate 14, the pressing distance of the T-shaped handle 2 can be controlled by the limiting plate 6, so as to achieve precise control of the insertion depth of the perforated tip. The above is the entire working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
