Description

Technical Field

[0001] This utility model relates to the field of agricultural production, and in particular to a soybean planting depth adjustment device. Background Technology

[0002] Soybeans, also known as yellow soybeans, are an important legume plant, known for being rich in high-quality protein, unsaturated fatty acids, and various vitamins and minerals. They are widely grown around the world and are a high-quality raw material for making tofu, soy milk, soybean oil, and many other food and industrial products.

[0003] A search revealed Chinese Patent Publication No. CN222263586U, which discloses a rapid perforation device for soybean planting, relating to the field of agricultural planting equipment technology. The device includes a mounting frame with a fixed handrail on top and a fixed handrail on top of the handrail. A seed drum is movably mounted on the mounting frame within the handrail. Multiple feeders are arranged on the outside of the seed drum, each feeder including a tube. An adjusting ring is movably mounted on the outside of the tube, and a barrier pad is movably mounted inside the tube. One end of the tube is fixedly mounted on the outside of the seed drum. Two mounting shafts are fixedly mounted on the mounting frame within the handrail, and a support rod is fixedly connected between the two shafts. The aforementioned application utilizes the handrail, mounting frame, and support rod to push the seed drum to roll within the planting field. The rolling seed drum sequentially inserts one end of each of the multiple tubes into the soil. Then, in conjunction with the adjusting ring, pad, and connecting rod, the seeds inside the seed drum automatically fall into the holes after perforation, thereby improving the efficiency of perforation and sowing.

[0004] Although the aforementioned application documents can achieve the effect of automatic hole punching and sowing, in actual use, due to the fixed length of the insertion tube, soybean seeds can only fall to the same depth. However, during the soybean planting process, the optimal planting depth needs to be determined based on factors such as seed quality, climate conditions, and soil type. Planting seeds at the same height can easily lead to poor planting results. Therefore, a soybean sowing depth adjustment device is proposed to solve the above problems. Utility Model Content

[0042] Reference Figure 1, Figure 4 and Figure 5 The sowing mechanism 5 also includes a pushing component 59, which includes a pushing groove 591. The pushing groove 591 is formed on the inner wall of the mounting block 3. A push rod 592 is slidably connected to the inner wall of the mounting block 3. The bottom end of the push rod 592 is in the same vertical region as the midpoint of the mounting block 3. The bottom end of the push rod 592 is elastically connected to the inner wall of the pushing groove 591 by a spring 593. One end of the spring 593 is fixedly connected to the bottom end of the push rod 592, and the other end of the spring 593 is fixedly connected to the inner wall of the pushing groove 591. A feeding pipe 6 is fixedly connected to the rear end of the mounting block 3. The upper region of the feeding pipe 6 is vertical, and the lower region of the feeding pipe 6 is inclined. A feeding hopper 7 is fixedly connected to the top end of the feeding pipe 6. The interior of the feeding hopper 7 is connected to the interior of the feeding pipe 6, and the bottom end of the feeding hopper 7 is inclined. The feeding pipe 6 is located at the lowest position of the bottom end of the feeding hopper 7. A connecting rod 8 is fixedly connected to the outer wall of the mounting block 3.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The bottom end of the connecting rod 8 is provided with a moving component 9, which includes a connecting plate 91. The connecting plate 91 is hollow cuboid in shape. The top end of the connecting plate 91 is fixedly connected to the top end of the connecting rod 8. The bottom end of the connecting plate 91 is provided with four rollers 92, which are located at the four corners of the bottom end of the connecting plate 91. The top end of the connecting plate 91 is fixedly connected with a control lever 93, which allows the operator to move the equipment by pulling the control lever 93.

[0044] Working principle: When in use, the operator first pulls the insert 27 outward so that the insert 27 leaves the socket 28, and then rotates the adjusting rod 26 so that the adjusting rod 26 drives the rotating disk 22 to rotate. As the rotating disk 22 rotates, the inner wall of the control groove 23 comes into contact with the control rod 25, thereby changing the distance between the control rod 25 and the mounting block 3, and thus changing the distance between the height control plate 24 and the mounting block 3.

[0045] After the adjustment is completed, the staff will reinsert the insert 27 into the new socket 28, thereby fixing the position of the rotating disk 22.

[0046] Subsequently, the staff pulled the control lever 93, which caused the control lever 93 to move the connecting plate 91. During the movement, because the bottom end of the baffle 55 is pointed, it rotates due to friction with the ground.

[0047] When the next baffle 55 is rotated to the bottom position, the worker puts an appropriate amount of soybean seeds into the hopper 7, so that the soybean seeds, under the action of gravity, enter the feed pipe 6 along the feed hopper 7, and then enter the interior of the mounting block 3, and finally enter the interior of the guide pipe 4 located below the mounting block 3.

[0048] At this time, the staff pushes the push rod 592 downward, which pushes the moving tube 51, causing the moving tube 51 to move downward. Since the baffle 55 is in a closed state at this time, the whole consisting of the baffle 55 and the moving tube 51 has a certain ability to push the soil.

[0049] When the control block 57 is moved to contact the top of the height control plate 24, as the moving tube 51 continues to move downward, the control block 57 cannot move downward, while the moving tube 51 moves downward. Therefore, the control block 57 moves upward relative to the moving tube 51, which causes the pull rope 58 to be pulled upward. This causes the pull rope 58 to open the baffle 55, allowing the seeds to fall into the soil. Since the height of the height control plate 24 is the height adjusted by the staff, it can ensure that the moving tube 51 moves to the height required by the staff, thus ensuring that the seeds can be planted at the optimal depth.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
