Description

Technical Field

[0001] The utility model relates to the technical field of corn and soybean sowing devices, in particular to a corn and soybean strip composite planting light and simplified sowing device. Background Art

[0002] At present, corn and soybean are common sowing crops. After sowing, transparent plastic film is covered on the ground through film covering technology to protect the growth of crop seedlings. When the temperature warms up, the film is uncovered to allow the seedlings to grow under normal climatic conditions. Through film covering technology, soil heat loss is reduced, soil moisture is maintained, weed growth is reduced, and soil structure is improved. From the soil perspective, decades of corn and wheat rotation have caused the land to be occupied by gramineous crops for a long time, resulting in a one-sided lack of soil nutrients. The main reasons are the single fertilizer demand of gramineous crops, the single use of herbicides, the long-term accumulation of specific pests and diseases, and the tendency of fertilization. This has caused serious soil compaction, difficulty in pest and disease control, greatly reduced fertilization efficiency, and serious imbalance of soil flora.

[0003] Common sowing patterns for sowing corn and soybeans include "2+2" (2 rows of soybeans, 2 rows of corn) and "3+2" (3 rows of soybeans, 2 rows of corn). The row spacing and plant spacing of corn planting depend on many factors, including planting methods, variety characteristics, soil conditions, etc. The planting interval also needs to consider soil water and fertilizer conditions. When water and fertilizer conditions are good, the row spacing should be appropriately increased, and when water and fertilizer conditions are poor, the row spacing should be appropriately reduced. The existing corn and soybean strip composite sowing device cannot adjust the sowing distance of corn and soybeans, and it is difficult to adjust the sowing distance of corn and soybeans according to soil water and fertilizer conditions. Utility Model Content

[0013] Furthermore, a feeding hopper is installed at the upper end of the box body for facilitating feeding seeds into the storage cavity through the feeding opening.

[0014] Furthermore, the limiting frame comprises a frame body, a limiting hole 1 for limiting the third connecting pipe is opened in the middle of the frame body, and a limiting hole 2 for limiting the adjusting component is opened in the middle of the frame body.

[0015] Furthermore, the limiting assembly includes an arc-shaped limiting block for limiting the adjusting assembly, and a bottom plate is installed on one side of the arc-shaped limiting block.

[0016] Furthermore, a convex spring piece is installed at the upper end of the base plate for cooperating with the arc-shaped limit block to limit the adjustment component, and fixing plates are installed on both sides of the convex spring piece. A bolt is installed in the middle of the fixing plate for cooperating with the base plate to lock the convex spring piece.

[0017] Furthermore, the adjustment assembly includes a baffle for sealing the third connecting pipe, a connecting rod for limiting the baffle is installed on the upper end of the baffle, a knob for cooperating with the connecting rod to rotate the baffle is installed on the upper end of the connecting rod, and a fixed block for cooperating with the convex spring sheet to limit the baffle is installed on the upper end of the baffle body.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] When it is necessary to adjust the spacing of the seeds, the adjusting component can be rotated to make the baffle block the bottom of the third connecting tube, and the seeds cannot fall through the third connecting tube. The inner interval is used to close the next adjusting component, so that the closed adjusting components are set at intervals, thereby achieving the adjustment of the seed sowing distance. When the knob is turned, the connecting rod is driven to rotate, so that the baffle rotates synchronously, and the fixed block slides from one side of the convex spring piece to the other side of the convex spring piece, driving the convex spring piece to deform. When the fixed block slides to the other side of the convex spring piece, the fixed block is limited by the side wall of the convex spring piece and the arc-shaped limit block, so that the baffle blocks the third connecting tube, which is convenient for adjusting the planting distance.

[0034] A storage box 200 for holding seeds is installed in the middle of the mounting frame 100, and the storage box 200 includes a box body 210, and a storage cavity 211 for storing seeds is opened inside the box body 210, and a discharge port 212 is opened at the upper end of the box body 210.

[0035] The upper end of the box body 210 is fixedly provided with a feeding hopper 220 for feeding seeds into the storage cavity 211 through the feeding port 212. Corn and soybean seeds are fed into the storage cavity 211 through the feeding hopper 220 and the feeding port 212, and the seeds fall into the first connecting pipe 230 through the trapezoidal lower hopper 213, and fall into the third connecting pipe 232 through the inclined second connecting pipe 231, and fall through the third connecting pipe 232 for planting. The storage box 200 includes a first connecting pipe 230 for conveying seeds, and a second connecting pipe 231 is fixedly installed at the left and right ends of the first connecting pipe 230, and a plurality of third connecting pipes 232 for facilitating seed sowing are fixedly installed at the lower end of the second connecting pipe 231. When the spacing of the seeds needs to be adjusted, the adjusting component 400 can be rotated so that the baffle 410 blocks the bottom of the third connecting pipe 232, and the seeds cannot fall through the third connecting pipe 232, and the inner interval of an adjusting component 400 closes the next adjusting component 400, so that the closed adjusting components 400 are arranged at intervals, thereby achieving the adjustment of the seed sowing distance. When the "2+2" and "3+2" modes are used for strip composite planting of corn and soybeans, the seed sowing distance of corn and soybeans can be adjusted, and after the seeds are sown, a film is covered on the top of the seeds for insulation to ensure the survival rate.

[0036] A limit frame 300 is fixedly installed at the lower end of the storage box 200, and the limit frame 300 includes a frame body 310.
