Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a multi-row spacing self-adjusting wheat and corn universal planter. Background Technology

[0002] As a major food crop, the quality of wheat sowing directly affects its yield. Precision sowing, reasonable dense planting, and uniform row spacing are key agronomic requirements for improving wheat yield. Traditional wheat and corn planters, especially multi-row planters, have many technical limitations in adapting to different planting patterns (such as wide and narrow rows, equal row spacing) and field conditions.

[0003] The sowing period for corn is affected by temperature and humidity. For spring-sown corn, the optimal sowing time is when the temperature is consistently around 15℃ within the top 7.6cm layer of soil. In North China, summer-sown corn should be sown promptly after the wheat or pea harvest. The sowing depth varies from 2.5 to 10cm depending on soil moisture, with 5-6cm being the most suitable. The sowing rate is 3-4kg per mu (approximately 0.067 hectares), resulting in 4000-6000 plants per mu.

[0004] The main disadvantages of existing multi-row wheat and corn planters are as follows: Inconvenient and low-precision row spacing adjustment: Most machines adjust row spacing by simply moving the seeding units on the frame or changing the mounting holes. This method is not only cumbersome, requiring the disassembly and reinstallation of multiple components (such as bolts), but also has limited adjustment precision, making it difficult to achieve continuous and precise stepless adjustment. It is unsuitable for situations requiring specific row spacing (such as wide-narrow row configurations) or fine-tuning to adapt to different field conditions. The adjustment process is complex and time-consuming: Changing row spacing often requires multiple people or additional tools, making adjustments in the field inefficient and affecting planting time. Frequent disassembly and installation also increase labor intensity and the probability of errors. Insufficient stability after adjustment: Using bolt hole fixing, the seeding units are prone to displacement or loosening during machine operation, especially when encountering bumps, causing the actual row spacing to deviate from the set value and affecting the uniformity of sowing. Utility Model Content

[0005] The purpose of this invention is to provide a multi-row spacing self-adjusting wheat and corn universal planter, which aims to solve the problems raised in the background art.

[0006] A multi-row spacing self-adjusting universal wheat and corn seeder includes,

[0007] Transport rack;

[0008] An adjustment assembly, located on the inner wall of the transport frame, includes: a limiting frame, a limiting groove, an adjustment frame, a moving groove, a moving block, an adjustment bolt, a lifting block, a drive rod, a rotating rod, a drag-reducing wheel, a mounting platform, and auxiliary components. The limiting frame is fixedly installed at the bottom edge of the outer wall of the transport frame. The limiting groove is formed in the outer wall of the limiting frame. The adjustment frame is embedded in the inner wall of the transport frame. The moving groove is formed in the inner wall of the adjustment frame. The moving block is bolted into the inner wall of the moving groove. The adjustment bolt is threaded... The lifting block is rotatably embedded in the bottom opening of the adjusting bolt, with one end of the driving rod rotatably inserted into the outer wall of the lifting block and the other end of the driving rod rotatably inserted into the inner wall of the rotating rod. The rotating rod is rotatably inserted into the outer wall of the moving block, with the drag-reducing wheel rotatably sleeved at the center of the outer wall of one end of the rotating rod via a rotating shaft. The mounting platform is sleeved at the center of the outer wall of one end of the rotating rod, with the drag-reducing wheel rotatably embedded in the inner wall of the limiting groove. The auxiliary component is located on the inner wall of the transport frame.

[0009] Furthermore, the auxiliary components include a protective shell, a limiting shell, a drive bolt, a limiting shaft, a release frame, and a roller cylinder.

[0010] Furthermore, the protective shell and the limiting shell are respectively sleeved on the outer wall of the transport frame, the release frame is slidably embedded in both sides of the inner wall of the transport frame, the limiting shaft is fixedly set in both sides of the outer wall of the release frame, and the limiting shaft is slidably embedded in the opening of the inner wall of the limiting shell.

[0011] Furthermore, the drive bolt is rotatably inserted into the inner wall of the release frame, the drive bolt is threadedly connected to the opening of the inner wall of the limiting shell, and the roller cylinder is rotatably embedded in the inner wall of the release frame.

[0012] Furthermore, the two ends of the movable groove are extended.

[0013] Furthermore, the top end of the limiting shaft is protruding, and the outer wall of the transport frame is fixedly provided with an installation shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The adjustment component is ingeniously designed to effectively achieve flexible, precise adjustment and stable operation of wheat sowing row spacing. Its flexible row spacing adjustment capability allows the moving block to slide freely and be fixed within the extended grooves at both ends, providing basic horizontal position adjustment for the sowing units on the mounting platform and meeting the initial requirements of different row spacing settings. Convenient fine-tuning and height control are achieved by rotating the adjustment bolt, which drives the lifting block to move vertically. The lifting block drives the drive rod, which in turn pushes the rotating rod to rotate around its axis. A stable spacing fine-tuning mechanism ensures that the rotation of the rotating rod causes a drag-reducing wheel at one end to roll within the limiting groove of the limiting frame. This design ensures that the movement trajectory of the rotating rod is precisely limited, thereby causing the mounting platform to generate precise horizontal displacement, enabling fine-tuning of the sowing unit spacing. Smooth movement is guaranteed by the rolling design of the drag-reducing wheel within the limiting groove, which significantly reduces frictional resistance during the adjustment process, making the spacing adjustment operation smoother and less labor-intensive.
