Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and particularly relates to a vetch sorting system. Background Art

[0002] In agricultural production, hairy vetch is an important crop that can be used as both green manure and forage, and its seed production is of great significance for sustainable agriculture. However, there are problems in the traditional single-cropping mode of hairy vetch, such as the plant growing prostrate, difficult mechanical harvesting, and low seed yield. In recent years, the intercropping mode of hairy vetch and cereal crops (such as wheat) has been promoted. This mode uses the upright stems of cereal crops to support the climbing growth of vetch, improves the space utilization rate, enhances photosynthesis, significantly increases the vetch seed yield (13.88%-23.45%), and realizes mechanized combined harvesting. However, after using a combine harvester to mix-harvest hairy vetch and cereal crops, the obtained seed mixture not only contains target seeds (such as hairy vetch and wheat), but also is mixed with a large amount of impurities such as broken wheat straws and soil particles. The existing air separation equipment mainly relies on the free fall of seeds combined with air separation. However, since the mixed seeds are prone to accumulate and disperse unevenly when falling, the air classification is not thorough, and it is difficult to completely remove the light impurities, affecting the sorting accuracy. Therefore, a vetch sorting system is developed. Summary of the Invention

[0003] The purpose of the present invention is to provide a vetch sorting system to solve the technical problems mentioned in the above background art.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

The bottom of the sorting cylinder is fixedly connected to the upper surface of the frame table through two groups of symmetrically arranged support rods. One end of the upper part of the sorting cylinder is provided with a feed hopper communicated with its interior. A pipe shaft is rotatably arranged in the middle of the sorting cylinder. One end of the pipe shaft close to the feed hopper extends to the outside of the sorting cylinder, and a first motor for driving the pipe shaft to rotate is arranged on the outside of the sorting cylinder. One end of the pipe shaft located outside the sorting cylinder is communicated with one end of an air supply pipe through a rotary joint, and the other end of the air supply pipe is communicated with the output end of an air pump fixedly arranged on the frame table. A spiral blade is sleeved on the part of the pipe shaft located inside the sorting cylinder, and air blowing pipes are arranged at the intervals of the spiral blade on the pipe shaft.

Detailed implementation manners

[0027] As Figures 1-8 shown, a vetch sorting system includes a frame table 1, above which a sorting cylinder 2 is fixedly installed. The bottom of the sorting cylinder 2 is fixedly connected to the upper surface of the frame table 1 through two groups of symmetrically arranged support rods 20.

[0028] One end of the upper part of the sorting cylinder 2 is provided with a feed hopper 3 communicating with its interior. A pipe shaft 4 is rotatably installed in the middle of the sorting cylinder 2. One end of the pipe shaft 4 close to the feed hopper 3 extends to the outside of the sorting cylinder 2, and a first motor 5 for driving the pipe shaft 4 to rotate is installed outside the sorting cylinder 2. In this embodiment, a first mounting plate 6 is fixedly arranged on the outer side of the end wall of the sorting cylinder 2 close to the feed hopper 3 by welding. The first motor 5 is fixedly installed on the first mounting plate 6. A driving pulley 7 is installed at the free end of the driving shaft of the first motor 5, and a driven pulley 8 is installed on the part of the pipe shaft 4 located outside the sorting cylinder 2. The driving pulley 7 and the driven pulley 8 are connected by a transmission belt 9.

[0029] One end of the pipe shaft 4 located outside the sorting cylinder 2 is connected to one end of an air supply pipe 11 through a rotary joint 10, and the other end of the air supply pipe 11 is connected to the output end of an air pump 12 fixedly installed on the frame table 1.

[0030] A spiral blade 13 is sleeved on the part of the pipe shaft 4 located inside the sorting cylinder 2, and an air blowing pipe 15 communicating with the inside thereof is arranged at the interval part of the spiral blade 13 on the pipe shaft 4.

[0031] A vetch sorting port 16 is formed in the middle of the bottom of the sorting cylinder 2, and a first sieve 17 capable of allowing vetch to pass through is arranged below the vetch sorting port 16, that is, the aperture of the sieve holes of the first sieve 17 is larger than the particle size of vetch seeds and smaller than the particle size of wheat seeds. A wheat sorting port 18 is formed at one end of the bottom of the sorting cylinder 2 away from the feed hopper 3, and a second sieve 19 capable of allowing wheat to pass through is arranged below the wheat sorting port 18, that is, the aperture of the sieve holes of the second sieve 19 is larger than the particle size of wheat seeds. A plurality of impurity removal ports 14 are evenly formed in the circumferential direction on the end wall of one end of the sorting cylinder 2 close to the wheat sorting port 18.

[0032] In this embodiment, each of the air blowing pipes 15 is specifically in an L shape. The vertical part of each air blowing pipe 15 is communicated with the pipe shaft 4, and the free end of the horizontal part of each air blowing pipe 15 faces the plurality of impurity removal ports 14. In addition, air permeable holes 21 are evenly and densely formed on the spiral blade 13.

[0033] When the invention works, the harvested vetch and wheat mixed seeds to be sorted are put into the sorting cylinder from the feed hopper. The first motor drives the pipe shaft to rotate. During the rotation of the spiral blade along with the pipe shaft, the mixed seeds inside the sorting cylinder can be stirred, and the mixed seeds are conveyed in a spiral conveying manner in a direction away from the feed hopper. During the conveying process, the mixed seeds first pass through the vetch sorting port, and the vetch seeds with smaller particle sizes pass through the first sieve; while the wheat seeds with larger particle sizes are intercepted by the first sieve and continue to be conveyed forward until they reach the wheat sorting port and pass through the second sieve. At the same time, the air flow generated by the air pump passes through the air supply pipe and the pipe shaft and is blown out from each air outlet pipe, and the lighter impurities such as straw mixed inside the seeds are blown out towards the impurity removal ports. Therefore, the invention realizes the automatic sorting of vetch and wheat seeds, avoids the situations of seed accumulation and uneven dispersion through the way of spiral conveying and stirring, and performs air separation on the light impurities such as straw and the target seeds, which is beneficial to improving the sorting efficiency and ensuring the sorting accuracy.

[0034] Vertical connecting plates 22 are symmetrically and fixedly arranged at both ends of the first sieve 17, and the two connecting plates 22 are respectively fixedly connected with a horizontal first connecting rod 23. Two limiting plates 24 are symmetrically and fixedly arranged at the bottom of the sorting cylinder 2, and through holes slidably matched with the corresponding ends of the first connecting rod 23 are respectively formed in the two limiting plates 24. A reciprocating driving mechanism for driving the first connecting rod 23 at the corresponding end to perform linear reciprocating motion is arranged at one end of the bottom of the sorting cylinder 2 close to the feed hopper 3.

[0035] In this embodiment, the reciprocating driving mechanism includes a second mounting plate 25 fixedly arranged at the bottom of the feeding hopper 3. A second motor 26 is fixedly mounted on one side of the second mounting plate 25. The driving shaft of the second motor 26 is connected to a turntable 27 rotatably mounted on the other side of the second mounting plate 25. A portion of the turntable 27 near the outer edge is hingedly connected to one end of a second connecting rod 28, and the other end of the second connecting rod 28 is hingedly connected to the first connecting rod 23.

[0036] When the second motor drives the turntable to rotate, since a crank-slider mechanism is formed among the turntable, the second connecting rod and the first connecting rod, the rotational motion of the turntable is converted into a linear reciprocating motion of the first connecting rod. During the process that the first connecting rod drives the first sieve to reciprocate, the screening efficiency of the vetch seeds inside the mixed seeds can be improved.

[0037] In addition, a third sieve 29 is inclinedly arranged below the first sieve 17 on the frame table 1. The aperture of the sieve holes of the third sieve 29 is smaller than the particle size of vetch. A dust outlet 30 is formed below the third sieve 29 on the frame table 1. Since small-diameter impurities such as soil particles are still mixed in the vetch seeds leaked from the first sieve, the above-mentioned small-diameter impurities can be effectively screened out through the screening action of the third sieve.

[0038] Side plates 31 are respectively fixedly arranged on both sides of the third sieve 29. A vibrator 32 is installed in the middle of the outer sides of the two side plates 31. Two vertical sliding rods 33 are symmetrically and fixedly arranged at the bottoms of the two side plates 31. Each sliding rod 33 is slidably matched with a through hole formed on the frame table 1. A spring 34 is sleeved on the portion of each sliding rod 33 located between the side plate 31 and the frame table 1. A limiting head 35 with a diameter larger than the inner diameter of the through hole on the frame table 1 is arranged at the lower end of each sliding rod 33. Through the above settings, since the side plates on both sides of the sieve are movably connected to the frame table through the sliding rods, after the vibrator is started, the third sieve works in a vibrating screening manner, thereby improving the screening efficiency of small-diameter impurities such as soil particles in the vetch seeds.

[0039] A vetch collecting hopper 36 is installed on the frame table 1 near the lower end of the third sieve 29. Under the action of gravity, the vetch seeds slide down along the third sieve, and thus are automatically collected through the vetch collecting hopper 36. A wheat collecting hopper 37 is installed under the second sieve 19 on the frame table 1. When the wheat seeds leak from the second sieve, they can be automatically collected through the wheat collecting hopper 37. In addition, collecting containers can be respectively arranged below the vetch collecting hopper and the wheat collecting hopper to realize the separate packaging of vetch seeds and wheat seeds.

[0040] The embodiments described above are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
