Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a harvesting device for fine forage grass seeds. Background Art

[0002] Forage generally refers to grass or other herbaceous plants fed by livestock. Forage has strong regeneration ability and can be harvested many times a year. It is rich in various trace elements and vitamins, so it has become the first choice for raising livestock. The quality of forage varieties directly affects the economic benefits of animal husbandry and needs to be taken seriously. Forage is generally planted by sowing forage seeds. Therefore, in order to obtain forage seeds, it is necessary to use harvesting equipment to harvest the forage seeds when they are mature.

[0003] Forage seed harvesting mainly includes a series of operations such as harvesting, drying, cleaning, and storage. When the forage seeds are mature, they are first harvested and separated by a harvester, and then dried on a drying rack or directly spread on the ground. When the moisture content of the forage seeds is reduced to the requirement, they are collected and impurities are removed. Finally, they can be put into sacks or seed storage bins, thus completing the entire harvesting process of forage seeds.

[0004] However, in the prior art, when drying forage seeds, the forage seeds are usually spread on a drying rack or on the ground for direct drying, and then they are turned over periodically by hand or by a turning machine. Although the forage seeds at the bottom can be turned over to the top for drying, the forage seeds are always piled together, so the drying effect is not good. It takes a long drying time to complete the drying operation of the forage seeds, and the drying efficiency is low. In view of this, the present invention is specially proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a harvesting device for fine grass seeds that can overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a harvesting device for fine grass seeds, comprising: a double-opening shell, which is a transparent shell; a second sieve plate, slidably installed in the double-opening shell; a discharge port is provided on one side of the double-opening shell near the second sieve plate, and a first cover plate is provided at the discharge port of the double-opening shell; a rotating shaft, rotatably connected to the inside of the double-opening shell and located below the second sieve plate; a driving motor, fixedly connected to one side of the double-opening shell, and the output end is fixedly connected to the end adjacent to the rotating shaft; an eccentric disk, equidistantly fixedly connected to the rotating shaft; a blowing mechanism for blowing air to the grass seeds, installed at the lower end of the double-opening shell.

[0011] In order to facilitate the pre-cleaning of larger impurities such as straw mixed in the forage seeds, it further includes a first sieve plate, which is slidably connected in the double-opening shell and is located above the second sieve plate. The first sieve plate and the second sieve plate are fixedly connected by a connecting rod, and the sieve hole diameter of the first sieve plate is larger than the sieve hole diameter of the second sieve plate.

[0012] In order to reduce the pressure load of the second screen plate on the rotating shaft and make the first screen plate and the second sieve plate shake more frequently, further, a fixed plate is slidably connected to the connecting rod, and the fixed plate is fixedly connected to the inner wall of the double-opening shell. A tensioning spring is sleeved on the connecting rod, and the two ends of the tensioning spring are respectively fixedly connected to the fixed plate and the first sieve plate.

[0014] In order to facilitate the sunlight to shine on the forage seeds through the drainage cover and ensure the drying effect of the forage seeds, the drainage cover is further designed to be transparent.

[0015] In order to facilitate the scraping of impurities attached to the inner wall of the double-opening filter cartridge and ensure the smoothness of gas passing through the filter holes of the double-opening filter cartridge, the double-opening filter cartridge is rotatably connected to the conveying pipe, the drainage cover is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a gear, the double-opening filter cartridge is fixedly connected to a gear ring meshing with the gear, a scraper is provided at the upper inner end of the double-opening filter cartridge, the scraper slides against the inside of the double-opening filter cartridge, and the scraper is fixedly connected to the conveying pipe through a bracket.

[0016] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: the present invention uses a double-opening shell, a second sieve plate, a driving motor, a rotating shaft, an eccentric disk and a blower mechanism and other components in coordination. Compared with the prior art which uses a drying net or a drying rack for drying, when the forage seeds are harvested and dried, the forage seeds can be shaken up and down and turned over on the second sieve plate, thereby ensuring that the forage seeds are fully exposed to light and in contact with the airflow, effectively improving the drying efficiency of the forage seeds, and at the same time can also have the effect of removing impurities from the forage seeds, effectively improving the cleanliness of the harvested seeds.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0027] Example 1: Reference Figure 1-Figure 6 A harvesting device for fine forage seeds comprises: a double-opening shell 1, which is a transparent shell; a second sieve plate 102, which is slidably installed in the double-opening shell 1; a discharge port is arranged at a position close to the second sieve plate 102 on one side of the double-opening shell 1, and a first cover plate 109 is arranged at the discharge port of the double-opening shell 1; a rotating shaft 106, which is rotatably connected inside the double-opening shell 1 and is located below the second sieve plate 102; a driving motor 107, which is fixedly connected to one side of the double-opening shell 1, and the output end is fixedly connected to the end adjacent to the rotating shaft 106; an eccentric disk 108, which is equidistantly fixedly connected to the rotating shaft 106; a blowing mechanism for blowing air to the forage seeds, which is installed at the lower end of the double-opening shell 1.

[0028] The hair blowing mechanism comprises a bellows 2 and a blowing head. The bellows 2 is fixedly mounted at the bottom of the double-opening housing 1. The blowing heads are equidistantly connected and arranged at the upper end of the bellows 2. A gas delivery component for delivering gas into the bellows 2 is mounted on the bellows 2.

[0029] The gas delivery assembly includes an air cylinder 201, a piston rod 202 with a piston, and a T-block 203. The air cylinder 201 is fixedly connected to a position inside the bellows 2 near the eccentric disk 108, the piston rod 202 is slidably connected in the air cylinder 201, and one end of the piston rod 202 extending upward out of the air cylinder 201 is fixedly connected to the T-block 203. A circle of T-shaped grooves is provided on the outside of the eccentric disk 108, and the T-block 203 is slidably connected in the T-shaped grooves of the adjacent eccentric disk 108. The air inlet pipe on the air cylinder 201 extends downward out of the bellows 2, and the air outlet pipe of the air cylinder 201 is located in the bellows 2. Check valves are installed in the inlet and outlet pipes of the air cylinder 201.

[0030] When the grass seeds are harvested from the ground and threshed, in order to ensure that the moisture content of the grass seeds meets the storage requirements, the grass seeds need to be aired. When the grass seeds need to be aired, the equipment is first moved to a relatively open field, and then the equipment is powered on. Then the staff can pour the grass seeds on the second sieve plate 102 in the double-opening shell 1. In actual use, the second sieve plate 102 with a suitable aperture can be selected according to the actual size of the grass seeds, so that the aperture size of the second sieve plate 102 is smaller than the particle size of the grass seeds, thereby ensuring that the grass seeds will not pass through the second sieve plate 102 and fall.

[0031] When the grass seeds are poured onto the second sieve plate 102 for drying, the drive motor 107 can be started, and the drive motor 107 will drive the rotating shaft 106 to rotate, and the rotating shaft 106 will drive the eccentric disk 108 to rotate. Since the second sieve plate 102 is slidably connected in the double-opening shell 1, the second sieve plate 102 will move back and forth up and down in the double-opening shell 1 driven by the eccentric disk 108, and then the grass seeds on the second sieve plate 102 will shake and flip up and down under the action of the second sieve plate 102. Since the double-opening shell 1 is transparent, it can ensure that the grass seeds are fully exposed to light, thereby effectively improving the drying efficiency of the grass seeds.

[0032] When the eccentric disk 108 rotates, the eccentric disk 108 will also drive the piston rod 202 to move up and down in the air cylinder 201 through the T-block 203. When the piston rod 202 moves upward, the external air can be drawn into the air cylinder 201. When the piston rod 202 moves downward, the gas in the air cylinder 201 can be transported into the bellows 2. As the piston rod 202 continues to move up and down in the air cylinder 201, the gas entering the bellows 2 will continue to increase. When the gas pressure in the bellows 2 reaches the pressure at which the blowing head is opened, the gas in the bellows 2 will be blown upward to the second sieve plate 102 through the blowing head. When the airflow passes through the second sieve plate 102, it will come into contact with the forage seeds, thereby having the effect of air-drying the forage seeds, and further improving the efficiency of drying the forage seeds.

[0033] Reference Figure 2 It can be seen that when the eccentric disk 108 rotates to the lowermost end, the piston rod 202 will move down to the bottom of the air cylinder 201. When the second sieve plate 102 moves down, the blowing head will blow air upward at the same time, so that when the second sieve plate 102 lifts up the grass seeds and moves down to separate from the grass seeds, the blowing head will blow gas to the grass seeds, so that when the grass seeds are lifted up and not piled up together, the gas blown upward can better blow away the impurities mixed in the grass seeds, so that the impurities can be separated from the grass seeds, thereby removing impurities from the grass seeds and effectively improving the cleanliness of the grass seeds.

[0034] Example 2: Reference Figure 1-Figure 6 , a harvesting device for fine grass seeds is basically the same as Example 1, and further, a fixing ring 204 is fixedly connected to the position of the air inlet pipe of the air cylinder 201 at the bottom of the bellows 2 through a fixing bolt, and a filter screen 205 is fixedly connected to the position of the opening at the lower end of the fixing ring 204. By arranging the filter screen 205 at the bottom of the bellows 2, when the piston rod 202 with a piston sucks the external gas into the air cylinder 201 and transports it into the bellows 2, the filter screen 205 can filter the dust and other impurities in the surrounding gas, so as to prevent the dust and other impurities from clogging the blowing head and affecting the blowing effect, and the dust and other impurities follow the gas to contact with the grass seeds, thereby affecting the cleanliness of the grass seeds.

[0035] Example 3: Reference Figure 1-Figure 6 , a harvesting device for fine forage seeds is basically the same as Example 2, and further, a movable base 3 is provided at the bottom of the bellows 2, and a plurality of support rods 301 are equidistantly fixedly connected to the side of the movable base 3 close to the discharge port of the double-opening shell 1, and the upper ends of the support rods 301 are rotatably connected to the bottom of the bellows 2, and a plurality of hydraulic telescopic rods 302 are equidistantly rotatably connected to the side of the movable base 3 away from the support rods 301, and the upper ends of the hydraulic telescopic rods 302 are rotatably connected to the bottom of the bellows 2.

[0036] By setting the movable base 3, when the equipment needs to be moved, the equipment can be easily moved by directly pushing it, which effectively improves the flexibility of the equipment. By setting the support rod 301 and the hydraulic telescopic rod 302, when the drying of the grass seeds is completed, the hydraulic telescopic rod 302 can be started, and then the hydraulic telescopic rod 302 will push the bellows 2 upward, and then the double-opening shell 1 and the second sieve plate 102 can be in a tilted state, and then the staff can place the collection box on the side close to the discharge port of the double-opening shell 1, and open the first cover plate 109. At this time, the grass seeds on the second sieve plate 102 will roll down along the second sieve plate 102, so that they can fall into the collection box through the discharge port for collection, and finally the grass seeds in the collection box are poured into the storage bin for storage.

[0037] Example 4: Reference Figure 1-Figure 6 , a harvesting device for fine grass seeds is basically the same as Example 3, and further includes a first sieve plate 101, which is slidably connected in the double-opening shell body 1 and is located above the second sieve plate 102. The first sieve plate 101 and the second sieve plate 102 are fixedly connected by a connecting rod 103. The sieve hole diameter of the first sieve plate 101 is larger than the sieve hole diameter of the second sieve plate 102. Through the setting of the first sieve plate 101, when the grass seeds are poured on the first sieve plate 101, the grass seeds can pass through the first sieve plate 101 and fall onto the second sieve plate 102 for storage, while larger impurities such as straw mixed in the grass seeds will remain on the first sieve plate 101, thereby achieving the removal of larger impurities in the grass seeds.

[0038] The connecting rod 103 is slidably connected with a fixing plate 104, which is fixedly connected to the inner wall of the double-opening housing 1. A tensioning spring 105 is sleeved on the connecting rod 103, and the two ends of the tensioning spring 105 are respectively fixedly connected to the fixing plate 104 and the first sieve plate 101. By sleeved with the tensioning spring 105 on the connecting rod 103, when the grass seeds pass through the first sieve plate 101 and fall onto the second sieve plate 102, as the grass seeds on the second sieve plate 102 continue to increase, the tensioning spring 105 can be tightened to the second sieve plate 102. 02 acts as an upward lifting force, thereby reducing the pressure load of the second sieve plate 102 on the rotating shaft 106, reducing the risk of bending of the rotating shaft 106, and effectively improving the service life of the rotating shaft 106. At the same time, when the rotating shaft 106 drives the first sieve plate 101 and the second sieve plate 102 to shake up and down through the eccentric disk 108, with the cooperation of the tensioning spring 105, the first sieve plate 101 and the second sieve plate 102 can also shake more frequently, thereby further improving the effect of lifting and turning the forage seeds.

[0039] Example 5: Reference Figure 1-Figure 6, a harvesting device for fine forage seeds is basically the same as Example 4, and further, a drainage hood 4 is connected to the opening at the upper end of the double-opening shell 1, and a discharge pipe 401 is connected to one side of the drainage hood 4, and a conveying pipe 402 is fixedly connected to the air outlet of the drainage hood 4, and a dust suction fan 403 is installed in the conveying pipe 402, and a double-opening filter cartridge 404 is connected to the air outlet of the conveying pipe 402, and a second cover plate 405 is installed at one end of the double-opening filter cartridge 404 away from the conveying pipe 402. When the bellows 2 blows gas upward through the blowing head, the dust suction fan 403 can be started at the same time, and then the dust blown by the bellows 2 The impurities separated from the grass seeds will be captured by the dust suction fan 403, and then the dust suction fan 403 will transport the impurities into the double-opening filter cartridge 404 through the conveying pipe 402 in cooperation with the drainage hood 4, and then the gas entering the double-opening filter cartridge 404 will pass through the filter holes and be discharged, while the impurities will be intercepted in the double-opening filter cartridge 404, effectively collecting the impurities and avoiding the impurities being directly discharged into the air, so that the staff still needs to clean it. It can not only ensure the removal effect of impurities in the grass seeds, but also collect the impurities in a centralized manner so that the staff can deal with them.

[0040] The drainage hood 4 is designed to be transparent. By designing the drainage hood 4 to be transparent, when the device is placed outdoors to dry grass seeds, it can be ensured that sunlight shines through the drainage hood 4 onto the grass seeds, effectively ensuring the drying effect of the grass seeds.

[0041] The double-opening filter cartridge 404 is rotatably connected to the conveying pipe 402, a servo motor 406 is fixedly connected to the drainage cover 4, a gear 407 is fixedly connected to the output end of the servo motor 406, a gear ring 408 meshing with the gear 407 is fixedly connected to the double-opening filter cartridge 404, a scraper 409 is provided at the upper end of the inner part of the double-opening filter cartridge 404, the scraper 409 slides against the inner part of the double-opening filter cartridge 404, and the scraper 409 is fixedly connected to the conveying pipe 402 through a bracket. When the dust suction fan 403 removes impurities in the forage seeds After being transported into the double-opening filter cartridge 404, the servo motor 406 can be started, and the servo motor 406 will drive the gear 407 to rotate. Since the double-opening filter cartridge 404 is rotatably connected to the conveying pipe 402, the gear 407 will drive the double-opening filter cartridge 404 to rotate through the ring gear 408, and then the scraper 409 will scrape the inner wall of the upper end of the double-opening filter cartridge 404 to scrape off the impurities attached to the inner wall of the double-opening filter cartridge 404, thereby ensuring the smoothness of the gas passing through the filter holes of the double-opening filter cartridge 404.
