Description

Technical Field

[0001] This utility model relates to the technical field of agricultural equipment, and in particular to a wheat sowing device. Background Technology

[0002] When sowing wheat, existing seeders open fine furrows and then put all the seeds into them. This results in a large number of seeds crowding into a small space, which is not conducive to seed uniformity. According to the growth habits of wheat, a single wheat seed can decompose into multiple tillers, especially at the autumnal equinox when the tillering rate is high. For example, when there is ample growing space, a single wheat seed can produce six groups of tillers. However, the accumulation of a large number of wheat seeds in the fine furrows leads to overcrowding, causing a single wheat seed to produce only two groups of tillers, thus affecting the wheat yield. Therefore, it is necessary to invent a wheat sowing device that can improve seed sowing uniformity and increase seed growing space while ensuring that the number of seeds remains constant. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a wheat sowing device.

[0004] This utility model discloses a wheat sowing device, comprising a support frame, a seed box, and a fertilizer box. The seed box and fertilizer box are respectively installed at the top of the support frame. It also includes a sowing component and a rotary tillage component. A sowing component is installed at each of the multiple output ends on the support frame, and a rotary tillage component is installed at the bottom of the support frame. In use, the support frame is mounted on a tractor, and the tractor drives the rotary tillage component to rotate via a chain and sprocket. This causes the rotary tillage component to break up the ground and prevent burrs. At the same time, the sowing component expands the sowing range of the seeds, further increasing the growth space of the seeds, thereby promoting the emergence of multiple tillers from a single seed and further increasing wheat yield.

[0005] Preferably, the rotary tillage assembly includes a first rotating shaft, a first rotary tiller blade, a second rotating shaft, and a second rotary tiller blade. A first bracket and a second bracket are provided at the bottom of the support frame. A first rotating shaft is rotatably mounted on the first bracket, and multiple sets of first rotary tiller blades are arranged in a spiral array at equal intervals on the first rotating shaft. A second rotating shaft is rotatably mounted on the second bracket, and multiple sets of second rotary tiller blades are mounted on the second rotating shaft. The first and second rotating shafts are synchronously driven by chains at their respective ends. The first and second rotating shafts are driven by a tractor via chain and sprocket transmission. When the tractor rotates, the first rotating shaft drives multiple sets of first rotary tiller blades to break up the soil and prevent soil compaction, while the second rotating shaft drives multiple sets of second rotary tiller blades to rotary till the soil, further preventing soil compaction.

[0006] Preferably, the sowing assembly includes a conveying pipe, a base shell, a tip, a guide plate, and a feed inlet adjustment component. The conveying pipe is connected to the output end of the seed box and the output end of the conveying pipe is connected to the top of the base shell. The base shell is duckbill-shaped, and a guide plate is provided inside the base shell. The guide plate is shaped with a higher center and lower sides. A tip is provided at the front end of the base shell, and a feed inlet adjustment component is provided at the top of the base shell. In use, the tip opens a furrow in the soil, and the seeds enter between the base shell and the guide plate through the conveying pipe. The guide plate, with its shape, ensures that the wheat seeds are evenly dispersed and discharged from the base shell, thereby achieving dispersed sowing of wheat seeds 1, increasing the growing space of the wheat seeds, and promoting the number of tillers. According to the land location, the operator adjusts the size of the outlet between the base shell and the guide plate using the feed inlet adjustment component to improve flexibility.

[0007] Preferably, the feed inlet adjustment assembly includes an adjustment plate, a strip opening, a nut, and a lead screw. The lead screw is provided on the foundation housing, and the strip opening is provided on the adjustment plate. The lead screw passes through the strip opening and is threadedly connected to the nut. According to the actual situation, the position of the lead screw in the strip opening is adjusted. After the adjustment is completed, the nut is threadedly connected to the lead screw, thereby completing the fixation of the adjustment plate. The outlet size between the adjustment plate, the foundation housing, and the guide plate is adjusted to improve flexibility and prevent soil clods from entering the outlet.

[0008] Preferably, it also includes an annular flat washer, and an annular flat washer is fitted on the lead screw; the nut increases the contact area with the adjusting plate through the annular flat washer, thereby improving the firmness.

[0009] Preferably, the conveying pipe is a square pipe; a square pipe reduces burrs and improves the uniformity of seed sowing.

[0010] Preferably, it also includes a pressing roller. The pressing roller is provided at the rear end of the support frame. The height of the pressing roller is adjusted by a screw. A set of rake teeth is detachably provided at the rear of the pressing roller. The pressing roller breaks up bumps or loosens the soil on the ground after sowing. When the soil moisture is high, the rake teeth can not only further level the land, but also form a thin layer of loose soil on the surface, avoiding the formation of soil compaction due to excessive loss of surface moisture a few days after sowing, which would hinder seedling emergence.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the support frame is installed on the tractor, and the tractor drives the rotary tiller to rotate through the chain and sprocket, thereby causing the rotary tiller to break up the ground and prevent burrs. At the same time, the seeding component expands the width of the seed sowing range, further increasing the seed growth space, thereby promoting the emergence of multiple tillers in one seed and further increasing wheat yield.

[0027] The material conveying pipe 8 is a square pipe;

[0028] It also includes a pressing roller 17, which is provided at the rear end of the support frame 1. The height of the pressing roller 17 is adjusted by a lead screw, and a set of rake teeth is detachably provided at the rear of the pressing roller 17.

[0029] In this embodiment, during use, the support frame 1 is mounted on a tractor. The first rotating shaft 4 and the second rotating shaft 6 are driven by the tractor via chain and sprocket transmission. When the tractor rotates, the first rotating shaft 4 drives multiple sets of first rotary tillers 5 to break up the soil and prevent soil erosion. At the same time, the second rotating shaft 6 drives multiple sets of second rotary tillers 7 to till the soil, and the tips 10 of the blades 10 open up furrows in the soil. Seeds enter between the soil base 9 and the guide plate 11 through the feed pipe 8. The guide plate 11 uses its own shape to guide the wheat seeds within the soil. With the cooperation of the soil, the wheat seeds are evenly dispersed and discharged from the soil cover 9, thereby achieving the dispersed sowing of wheat seeds 1, increasing the growing space of wheat seeds, and promoting the number of tillers of wheat seeds.

[0030] This utility model discloses a wheat sowing device. The overall structure of the device is moved forward, resulting in a compact design that reduces the burden on the tractor when turning. The feed pipe uses a rectangular iron pipe, which occupies less area than a circular iron pipe, increasing both the soil-discharging area and the pipe's rigidity, thus reducing the likelihood of pipe breakage or bending. Two types of rotary tillers, of varying lengths, are used, forming two circles of different sizes during operation, keeping the blades as close as possible to the feed pipe. While the rotary tiller drives the rotary tiller to till and break up the soil, it also clears away soil and debris from the sides and front of the feed pipe, reducing the chance of soil accumulation and soil bridging. The rotary tiller is connected to a chain and sprocket. The rotating shaft No. 2 rotates, and the No. 2 rotary tiller blade rotates in the same direction as the No. 1 rotary tiller blade. This not only cleans the debris and soil on each pair of feed pipes, but also cleans the debris and soil on each pair of soil bases. This achieves the goal of significantly increasing the total area of ​​the seed strip without soil accumulation or building structures, and enables rapid sowing. It solves the problem that a wide seed strip area would lead to soil accumulation and building structures, making sowing impossible. The No. 1 rotary tiller blade 5 of this wheat sowing device is commercially available. Technical personnel in this industry only need to follow the accompanying instruction manual for installation and operation, without requiring any creative work from those skilled in the art.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
