Description

Technical Field

[0001] The present invention belongs to the technical field of green manure sowing equipment, and in particular relates to a precision sowing equipment for green manure in the milky stage of wheat for wheat intercropping. Background Art

[0002] As resource and environmental constraints gradually increase, it is increasingly difficult to increase grain production and yield. In addition, with the continued growth in demand, the pressure to ensure stable production and supply has increased dramatically. Food security has become a key issue of great concern to the Party and the country. At present, the intensive planting system in grain production in Gansu irrigation areas has caused soil degradation and prominent environmental problems due to the single crop, which is very unfavorable for the continuous increase in regional grain production. Corn / wheat intercropping is a traditional high-yield grain-increasing technology used in Gansu irrigation areas. By intercropping green manure with wheat, the original technology has achieved major innovations in content. While fully demonstrating its yield-increasing advantages, it can achieve soil moisture conservation and fertilization and improve arable land production capacity through inter-annual rotation of corn and wheat crops and turning over and returning green manure to the field, thereby providing technical support for the continuous increase in regional grain production. With the advancement of high-standard farmland construction and the supporting application of water-fertilizer integration technology, the development trend of technology in Gansu irrigation areas is getting better and better, and the application area is increasing year by year.

[0003] However, due to the lack of supporting seeders, the technology of sowing green manure during the milky stage of wheat is mainly dependent on manual labor. Not only is the production cost high when it is applied, but it is also greatly affected by the lack of farming labor in rural areas of the region, which seriously affects and restricts its large-scale promotion and application in Gansu irrigation areas.

[0004] Based on this, a precision sowing equipment for green manure in the milky stage of wheat for intercropping was proposed. Summary of the invention

[0009] Eight groups of lifting type sowing sleeves are fixed to the tail end of the sowing rack, and the seed outlet is communicated with adjacent lifting type sowing sleeves through an arc tube.

[0010] Furthermore, a micro cylinder is fixed outside the inner roller near each screening slot, the telescopic shaft of the micro cylinder is sleeved in the screening slot, and an arc-shaped elastic sheet with the same length as the screening slot is fixed on the top of the micro cylinder.

[0011] Furthermore, four sides of the arc-shaped elastic sheet are against the screening groove.

[0012] Furthermore, a first flexible brush is fixed to the top end of the outer cylinder, and the length of the first flexible brush is equal to the difference between the inner ring radius of the outer cylinder and the outer ring radius of the hard intermediate member. A first flexible plate is arranged in the outer cylinder at a position at least 60 degrees away from the first flexible brush along the rotation direction of the inner roller, and the first flexible plate has the same length as the first flexible brush.

[0018] Furthermore, a feeding port is provided at the top of the green manure seed bin, and an independently controlled pipeline valve is provided on the seed guide pipe.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The present invention installs a sowing and screening mechanism at the oblique section of the sowing frame, which is composed of eight sowing and screening units fixed to each other on the same axial line. The discharge port of the green manure seed bin is externally connected to eight seed guide tubes inclined downward. The tail end of each seed guide tube is respectively connected to the adjacent sowing and screening units, so that the sowing of eight rows of green manure seeds can be completed at a time, which is convenient for the efficient sowing operation of green manure seeds in the wheat field in the milky stage.

[0021] 2. The seeding and screening unit of the present invention comprises an outer cylinder, an inner roller, a hard intermediate body, a screening slot, a seed inlet and a seed outlet. The inner roller is rotatably connected in the outer cylinder, the outer cylinder is fixed on the seeding frame, and a driving motor for driving the inner roller to rotate is fixed on the outer side of the outer cylinder. A hard intermediate body with a circular cross section is fixed on the inner roller between the outer cylinder and the inner roller. The outer circumference of the hard intermediate body is evenly provided with at least six screening slots in a circular shape. A seed inlet is provided on the outer cylinder near the seed guide tube at a position deviating from the top of the outer cylinder, and a seed outlet is provided at the bottom of the outer cylinder. The seeds enter through the seed inlet. The green manure seeds in the outer cylinder can stay in the screening groove, and with the rotation of the inner roller, the green manure seeds are brought out through the seed outlet under the action of the screening groove. In order to facilitate the adjustment of the depth of the screening groove, the arc-shaped elastic sheet can be driven in the screening groove by the extension and contraction of the micro-cylinder. When the micro-cylinder is pushed outward, the depth of the screening groove can be reduced, thereby reducing the sowing amount of green manure seeds at a single time. When the arc-shaped elastic sheet shrinks in the micro-cylinder to fit the bottom surface of the screening groove, the screening groove screens the green manure seeds to the maximum amount at a time, thereby facilitating the precise control of the single sowing of green manure seeds through the screening groove.

[0022] 3. The present invention fixes a first flexible brush at the top of the outer cylinder. The length of the first flexible brush is equal to the difference between the inner radius of the outer cylinder and the outer radius of the hard intermediate. The green manure seeds accumulated on the top of the screening groove can be brushed off by the first flexible brush to complete the first screening, thereby avoiding blockage when the green manure seeds move in the screening groove. A first flexible plate is arranged in the outer cylinder at least 60 degrees away from the first flexible brush along the rotation direction of the inner roller. The first flexible plate can perform a second screening on the screening groove that has been screened by the first flexible brush.

[0023] 4. The present invention fixes a second flexible plate on one side of the seed entrance in the outer cylinder. The first flexible plate and the second flexible plate have the same length and the hardness of the first flexible plate is less than that of the second flexible plate. The second flexible plate can prevent the seeds from retreating into the outer cylinder under the action of inertia, thereby completing the sowing of green manure seeds. In addition, a second flexible brush is arranged in the outer cylinder at a position at least 60 degrees away from the second flexible plate along the rotation direction of the inner roller. The length of the second flexible brush is greater than that of the first flexible brush, and the difference in length between the second flexible brush and the first flexible brush is the same as the depth value of the screening groove. The second flexible brush can extend into the screening groove to scrape off the green manure seeds attached to the screening groove, which is conducive to repeated and accurate use of the screening groove.

[0024] The present invention has eight groups of lifting sowing sleeves fixed on the tail end of the sowing frame, and the seed outlet is connected to the adjacent lifting sowing sleeves through an arc tube. The rotation of the driving gear can drive the sleeve depth of the inner tube in the outer tube, so as to complete the height adjustment of the bottom end of the lifting sowing sleeve, so as to facilitate the sowing of green manure seeds in wheat fields at different heights in the milky stage.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-3 As shown, the present invention provides a technical solution: a precision sowing device for wheat milk-ripening green manure for wheat intercropping, comprising a sowing frame 1, a mounting frame 11 is fixed on the forward direction of the sowing frame 1, and the sowing frame 1 is connected to an external power device through the mounting frame 11, so that the sowing frame 1 can be driven to move for sowing operations.

[0032] In order to avoid damage to the wheat during the milky stage, two large driving wheels 2 are rotatably mounted on the bottom side of the sowing frame 1 through a connecting frame 12. The spacing between the two large driving wheels 2 is 140 cm, and the height of the large driving wheels 2 is 96 cm.

[0033] A green manure seed bin 3 is fixed on the sowing rack 1, a feeding port 31 is arranged at the top of the green manure seed bin 3, and an independently controlled pipeline valve is arranged on the seed guide pipe 32. The green manure seed bin 3 is used to place green manure seeds to be sown.

[0034] A sowing and screening mechanism 4 is installed at the oblique section of the sowing frame 1, and the sowing and screening mechanism 4 is composed of eight sowing and screening units fixed to each other on the same axial line. The discharge port 3 of the green manure seed bin 3 is externally connected to eight seed guide tubes 32 inclined downward, and the tail end of each seed guide tube 32 is respectively connected to the adjacent sowing and screening unit;

[0035] The sowing and screening unit comprises an outer cylinder 41, an inner roller 42, a hard intermediate body 43, a screening slot 44, a seed inlet 45 and a seed outlet 46, wherein the inner roller 42 is rotatably connected in the outer cylinder 41, the outer cylinder 41 is fixed on the sowing frame 1, and a driving motor for driving the inner roller 42 to rotate is fixed on the outer side of the outer cylinder 41, a hard intermediate body 43 with a circular cross section is fixed between the outer cylinder 41 and the inner roller 42, and at least six screening slots 44 are evenly opened on the outer circumference of the hard intermediate body 43 in a circular shape, a seed inlet 45 is opened on the outer cylinder 41 at a position close to the seed guide tube 32 deviating from the top end of the outer cylinder 41, and a seed outlet 46 is opened at the bottom end of the outer cylinder 41, and the green manure seeds entering the outer cylinder 41 through the seed inlet 45 can stay in the screening slot 44, and as the inner roller 42 rotates, the green manure seeds are taken out through the seed outlet 46 under the action of the screening slot 44;

[0039] A second flexible plate 73 is fixed on one side of the seed outlet 46 near the seed inlet 45 in the outer cylinder 41. The first flexible plate 72 and the second flexible plate 73 have the same length, and the hardness of the first flexible plate 72 is less than that of the second flexible plate 73.
