Description

Technical Field

[0001] The utility model relates to the technical field of seeding in breeding experimental fields, and particularly relates to a seeding device for agricultural breeding experimental fields. Background Technique

[0002] Different from large-scale planting in production, seeding in breeding experimental fields mainly has two characteristics: one is that the seeding requirements are accurate, neither missing seeding nor repeating seeding is allowed; the other is that the seeding speed is required to be rapid, and the entire experiment needs to be planted within the specified time.

[0003] When installing the current conventional seeding device, it is necessary to slide the assembly frame along the outer wall of the sliding rod, adjust the spacing of multiple assembly frames, and then fill the seeding box and install it in the middle of the top of the assembly frame. There are fixing grooves on the outer wall of the assembly frame, and the seeding box is correspondingly provided with fixing rods that fit the fixing grooves. During installation, the fixing rods need to be sleeved on the inner wall of the fixing grooves for positioning, and then the fixing pieces of the seeding box are fastened and fixed by the spring buckles of the assembly frame. Since the ground of the breeding field is uneven, the seeding device will shake during seeding, and the spring will be jolted during the shaking process, causing it to bounce off the fixing piece, releasing the connection between the assembly frame and the seeding box, resulting in the seeding box falling off. Therefore, a seeding device for agricultural breeding experimental fields is designed. Content of the Utility Model

[0031] Specifically, an adjusting rod 301 is connected through the top end of the assembly frame 2 and at one end close to the first screw 202. A furrowing blade 3 is provided at the bottom end of the assembly frame 2. The bottom end of the adjusting rod 301 is fixedly connected to the top end of the furrowing blade 3. A soil covering blade 302 is hinged to one end of the furrowing blade 3 close to the armrest 102.

[0032] It should be noted that the adjusting rod 301, the furrowing blade 3 and the soil covering blade 302 refer to the furrowing assembly of a push-type seeding machine of model BED. A round hole is provided at the position of the assembly frame 2 close to the assembly frame 2. By passing the adjusting rod 301 through the round hole, during operation, by pressing, the adjusting rod 301 is pressed down, and at the same time, the furrowing blade 3 and the soil covering blade 302 are inserted into the ground together. When the roller drum 101 is pushed, the roller drum 101 drives the furrowing blade 3 during movement. The furrowing blade 3 can cultivate the land for seeding, and at the same time, the connected soil covering blade 302 will level the cultivated land and bury the seeds in the ground.

[0033] Specifically, a slide rail 5 is provided at the top end of the assembly frame 2 and at one end close to the armrest 102. The outer wall of the second screw 601 is threadedly inserted through the top end of the sliding baffle 502. A threaded groove 602 is provided at the top end of the assembly frame 2 and at one end close to the sliding baffle 502. The outer wall of the threaded groove 602 is threadedly connected to the bottom end of the second screw 601.

[0034] It should be noted that the sliding baffle 502 can slide along the slide rail 5 through the slider 501. A threaded hole is provided at the top end of the sliding baffle 502, and a connecting rod is provided at the bottom end of the seeding box 4. An "L"-shaped connecting groove is provided at one end of the top end of the assembly frame 2 close to the seeding box 4. By sliding the connecting rod into the bottom end of the connecting groove, the position of the seeding box 4 can be fixed. The sliding baffle 502 slides towards the seeding box 4. When the sliding baffle 502 slides to the bottom end of the slide rail 5, the sliding baffle 502 can press and cover the fixing piece 6. At the same time, the threaded hole will be aligned with the position of the threaded groove 602. The second screw 601 is threadedly inserted through the threaded hole and threadedly connected with the threaded groove 602, so that the sliding baffle 502 can be fixed by the second screw 601, and at the same time, the position of the fixing piece 6 is fixed, so that the seeding box 4 is fixed on the inner wall of the assembly frame 2.

[0035] Working principle of the present utility model:

[0036] Specific operation is that the operator needs to slide multiple assembly frames 2 along the sliding rod 201 to adjust the seeding spacing, and then rotate the first screw 202. By using the threaded fit between the first screw 202 and the assembly frame 2, the bottom end of the first screw 202 resists the sliding rod 201 to fix the assembly frame 2. Then, the seeding box 4 is sleeved on the top end of the assembly frame 2. The operator needs to push the sliding baffle 502, and the sliding baffle 502 will slide along the slide rail 5 by using the slider 501. It is necessary to slide the sliding baffle 502 to the top of the fixing piece 6 and completely cover it. At the same time, the second screw 601 can be threadedly inserted through the sliding baffle 502 and threadedly connected with the threaded groove 602, so that the position of the sliding baffle 502 is fixed and at the same time the movement path of the fixing piece 6 is blocked. Then, the adjusting rod 301 can be pressed to press the furrowing blade 3 to the ground. The operator pushes the handrail 102 to push the roller cylinder 101 for seeding. During the seeding process, the seeding device will use the furrowing blade 3 to reclaim the ground. At the same time, the seeding box 4 will intermittently drop seeds onto the land, and finally the covering blade 302 will level the land and bury the seeds into the ground under the rolling of the roller cylinder 101.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
