Description

Technical Field

[0001] The utility model relates to the technical field of agricultural seeders. Specifically, it is a furrowing device for sowing flax germplasm resources. Background Art

[0002] Flax is a major oil crop and cash crop in the northwest and north China regions of our country. The oil content of flax seeds is 30% - 45%. Flax seeds are relatively small, and their ability to push through the soil during the seedling emergence stage is relatively weak. Therefore, flax has certain requirements for sowing depth. Secondly, it is necessary to ensure that the soil is loose and the particles are relatively fine to ensure smooth seedling emergence. Currently, flax is generally sown using a wheat seeder. When sowing flax germplasm resources, it is difficult to ensure the sowing situation of the seeds, which easily leads to a decrease in the emergence rate and waste of resources. Content of the Utility Model

[0003] For this reason, the technical problem to be solved by the utility model is to provide a furrowing device for sowing flax germplasm resources that can improve the sowing effect of flax seeds and the utilization rate of flax germplasm resources.

[0004] To solve the above technical problem, the utility model provides the following technical solution: A furrowing device for sowing flax germplasm resources, including a rotating cylinder, a bucket, a conical cylinder, and a stirring and mixing cylinder. Two or more of the buckets are arranged on the outer wall of the rotating cylinder at equal intervals along its circumferential direction. The small-diameter end of the conical cylinder is inserted into the rotating cylinder and coaxially and fixedly connected to the bottom of the conical cylinder. One end of the stirring and mixing cylinder is coaxially and fixedly connected to the large-diameter end of the conical cylinder. The rotation axis of the rotating cylinder is perpendicular to the furrowing and sowing direction. The bucket is communicated with the small-diameter end of the conical cylinder through a connecting pipe. The rotating cylinder is driven to rotate by an external power source. An opening is provided on the side wall of the stirring and mixing cylinder. A seed supply pipe is attached to one side of the stirring and mixing cylinder. A sowing pipe is attached to the bottom of the stirring and mixing cylinder. In the forward direction of furrowing and sowing: the outlet end of the sowing pipe is located directly behind the rotating cylinder. By setting a rotatable rotating cylinder to drive the bucket to rotate, furrows can be opened on the land. At the same time, a part of the crushed soil is shoveled up by the bucket and mixed evenly with the seeds and then sown into the furrows, so that the seeds are evenly dispersed in the furrows, avoiding the aggregation of small flax seeds in a group. At the same time, after the soil and seeds are mixed and sown into the furrows, each seed can be wrapped by the finely crushed soil, avoiding the seeds from hanging in the air and ensuring the germination rate.

[0005] In the above-mentioned furrowing device for sowing flax germplasm resources, the inner diameter of the stirring and mixing cylinder gradually decreases from the middle to both ends, and the opening is provided at the middle position of the axial length of the stirring and mixing cylinder. By setting a drum-shaped stirring and mixing cylinder, the seeds and soil can automatically converge towards the middle, improving the mixing and stirring effect.

[0006] For the above flax germplasm resource sowing and furrowing device, a plurality of stirring plates are equidistantly installed on the inner wall of the stirring and mixing cylinder along the circumferential direction. By providing the stirring plates, the stirring effect can be further improved.

[0007] For the above flax germplasm resource sowing and furrowing device, the discharge end of the seed supply pipe is in clearance fit with the side wall of the stirring and mixing cylinder, and the discharge end of the sowing pipe is in clearance fit with the side wall of the stirring and mixing cylinder. A circle of bristles is densely arranged on both the discharge end of the seed supply pipe and the discharge end of the sowing pipe, and the end of the bristles is in contact with the side wall of the stirring and mixing cylinder. By providing the bristles, the fitting effect between the pipeline and the side wall of the stirring and mixing cylinder is improved, and leakage is avoided.

[0008] For the above flax germplasm resource sowing and furrowing device, in the rotation direction of the rotating cylinder: a digging opening is provided on the front side of the bucket; a sieve is inclined in the rotating cylinder, and both sides of the sieve are connected to the side wall surfaces of both sides of the bucket. One end of the sieve is connected to the position of the bottom wall of the bucket away from the rotating cylinder, and the other end of the sieve extends towards the position of the digging opening and is connected to the rotating cylinder. By providing the sieve, during the rotation of the rotating cylinder, the soil in the bucket is automatically screened. The fine soil enters the stirring and mixing cylinder to be mixed with the seeds, fully wrapping the seeds. For the relatively coarse soil particles, during the rotation of the bucket, they fall from the bucket and are filled into the sowing furrow again to cover the fine soil mixed with the seeds, realizing synchronous covering and ensuring a certain air permeability. During the subsequent compaction process, it will not cause excessive burial of the seeds. During the subsequent irrigation process, water can quickly and directly contact the seeds.

[0009] For the above flax germplasm resource sowing and furrowing device, a baffle is provided in the digging opening of the bucket. One end of the baffle is connected to the rotating cylinder, and the other end of the baffle extends towards the middle position of the digging opening. The length of the baffle is less than half of the length of the digging opening. By providing the baffle, the premature dropping of the relatively coarse soil particles after screening is avoided.

[0010] For the above flax germplasm resource sowing and furrowing device, in the longitudinal section along the axis of the rotating cylinder: the distance between the side wall surfaces of both sides of the bucket gradually decreases from the end connected to the rotating cylinder to the free end. By providing a V-shaped bucket, the sowing furrow presents a V shape, and the soil mixed with the seeds can automatically gather towards the middle, and the soil can evenly fill the sowing furrow, avoiding the appearance of cavities.

[0011] The above-mentioned flax germplasm resource sowing and trenching device further includes a vehicle body, on which a height adjustment component is fixedly installed. The end of the height adjustment component extends downward below the vehicle body. A rotating shaft is fixedly installed on one side of the rotating cylinder, and the rotating shaft is rotatably connected to the end of the height adjustment component. The rotating cylinder is drivingly connected to a motor through the rotating shaft. By providing the height adjustment component, different sowing depth requirements can be met.

[0012] In the above-mentioned flax germplasm resource sowing and trenching device, the height adjustment component includes a lifting rod and a fixed sleeve. The fixed sleeve is fixedly installed on the vehicle body, and the lifting rod passes through the fixed sleeve. A pressing bolt is installed on the side wall of the fixed sleeve, and the end of the pressing bolt presses against the side wall of the lifting rod. The rotating cylinder is rotatably installed on the side wall of the lifting rod through the rotating shaft. The sowing pipe and the seed supply pipe are respectively connected to the lifting rod through brackets.

[0013] In the above-mentioned flax germplasm resource sowing and trenching device, a storage hopper is provided on the top of the vehicle body, and the bottom of the storage hopper is communicated with the end of the seed supply pipe through a hose. Wheels are provided on both sides of the vehicle body, and a handrail is fixedly installed on the top of the vehicle body.

[0014] The technical solution of the present utility model has achieved the following beneficial technical effects:

[0015] By providing a rotating bucket, while trenching on the soil surface, the soil and seeds are mixed and then dialed into the trench, so that the seeds are fully wrapped by the soil, avoiding the seeds from hanging in the air and ensuring the emergence rate.

[0016] By providing a sieve mesh to screen the soil, the fine soil is mixed with the seeds for sowing, further improving the wrapping effect on the seeds. The coarser soil covers the upper layer for soil covering, comprehensively improving the emergence rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] As shown Figure 2 As shown, a storage hopper 15 is provided on the top of the vehicle body 11. The bottom of the storage hopper 15 is communicated with the end of the seed supply pipe 7 through a hose. Seeds in the storage hopper 15 enter the seed supply pipe 7 through the hose under the action of gravity. When the opening 6 rotates to the end of the seed supply pipe 7, the seeds enter the stirring and mixing cylinder 4 through the opening 6 for mixing.

[0024] As shown Figure 2 As shown, the discharging end of the seed supply pipe 7 is in clearance fit with the side wall of the stirring and mixing cylinder 4, and the discharging end of the sowing pipe 8 is in clearance fit with the side wall of the stirring and mixing cylinder 4. A circle of bristles is densely arranged on both the discharging end of the seed supply pipe 7 and the discharging end of the sowing pipe 8, and the ends of the bristles are in contact with the side wall of the stirring and mixing cylinder 4.

[0025] As shown Figure 2 As shown, the inner diameter of the stirring and mixing cylinder 4 gradually decreases from the middle to both ends. The opening 6 is opened at the middle position of the axial length of the stirring and mixing cylinder 4. A plurality of stirring plates 5 are equidistantly installed on the inner wall of the stirring and mixing cylinder 4 along the circumferential direction to improve the stirring effect.

[0026] As shown Figure 3As shown in the figure, in the rotation direction of the rotating cylinder 1: the front side of the bucket 2 has a digging opening; a screen 10 is inclined in the rotating cylinder 1, and both sides of the screen 10 are connected to both side walls of the bucket 2. One end of the screen 10 is connected to the position of the bottom wall of the bucket 2 away from the rotating cylinder 1, and the other end of the screen 10 extends towards the position of the digging opening and is connected to the position of the rotating cylinder 1; in the longitudinal section along the axis of the rotating cylinder 1: the distance between the two side walls of the bucket 2 gradually decreases from the end connected to the rotating cylinder 1 to the free end.

When the opening 6 of the stirring and mixing cylinder 4 rotates to the position of the seed supply pipe 7, the seeds enter the stirring and mixing cylinder 4 through the opening 6 under the action of gravity. As the stirring and mixing cylinder 4 rotates, the soil and seeds are mixed. When the opening 6 rotates to the position of the sowing pipe 8, under the action of gravity, the seeds and soil enter the sowing pipe 8 and slide backward into the soil trench for sowing; the coarse-grained soil in the bucket 2 rotates with the bucket 2. When the digging opening of the bucket 2 faces downward, the coarse-grained soil slides down to cover the seeds. In order to improve the covering effect of the coarse-grained soil, a diversion plate can also be set to collect the falling coarse-grained soil and uniformly discharge it from above the soil trench.
