Description

Technical Field

[0001] The invention relates to the technical field of seed processing, and in particular discloses a material turning and recycling device for seed drying. Background Art

[0002] Some crop seeds need to be dried, dehydrated, and dried before storage. When drying seeds, they are usually laid on the ground and the drying process is completed by sunlight. After the seeds are dried, they need to be recovered, and in order to ensure that the upper and lower layers of the spread seeds are evenly dried, they often need to be turned up and down. At present, the existing seed recycling is usually done manually by using a broom or shovel to collect and bag them, which not only has low work efficiency, but also collects the dust on the ground together with the seeds. In addition, manual turning of seeds is usually handled with a rake, and the rake cannot effectively turn the upper and lower layers of seeds, resulting in the need to cooperate with multiple sets of tools during the seed drying process, and the work efficiency and effect are not ideal.

[0003] The invention patent with application number 2023111555351 discloses a rice seed transportation and storage device, including a mounting frame, a temporary storage box and a conveyor belt device with a self-contained driving mechanism. The mounting frame is a frame-type structure, and a universal wheel is fixedly installed at the bottom of the mounting frame. The conveyor belt device and the temporary storage box are both installed on the mounting frame, and the conveyor belt device extends above the temporary storage box; it also includes a logistics mechanism, which is installed on the mounting frame, and the logistics mechanism cooperates with the temporary storage box and the conveyor belt device. Although the technical solution disclosed in this patent can realize the collection of seeds after drying, the seeds enter the reflux channel formed between the mounting frame and the conveyor belt device through the flow groove on the operating cylinder under the action of the paddle, and can only be transported to the temporary storage box counterclockwise under the action of the conveyor belt device, and the seeds cannot be turned up and down during the drying process. In addition, when the paddle sweeps up the seeds, it will collect the dust on the ground together, and the dust cannot be effectively treated, resulting in further dust removal operations in the subsequent treatment of the seeds, which increases the treatment process before seed storage. Based on the above-mentioned deficiencies of the existing rice seed transportation and storage devices, the present application proposes a seed drying turning and recovery device that can effectively solve the above-mentioned technical problems.

[0006] As a further configuration of the above scheme, a dust suction mechanism is provided on the conveying device, and the dust suction mechanism includes a dust suction fan, a filter box and a dust extraction pipe connected in sequence. The upper surface of the conveying box is provided with an upwardly protruding suction chamber shell, and the dust extraction pipe is connected to the suction chamber shell.

[0007] As a further configuration of the above scheme, the dust suction mechanism also includes a fixed bar fixed inside the conveying box, a movable bar is arranged below the fixed bar, and a spring is connected between the movable bar and the fixed bar, the movable bar is provided with a plurality of impact heads passing through the guide holes on the fixed bar, and the impact heads are arranged toward the inner surface of the conveyor belt at the position of the suction chamber shell, a rotating shaft is arranged beside the movable bar, and a pressing cam acting on the movable bar is arranged on the rotating shaft.

[0008] As a further configuration of the above scheme, one end of the rotating shaft is extended out of the conveying box, and a belt transmission assembly is arranged between the end of the rotating shaft extending out of the conveying box and the roller shaft of the upper conveying roller.

[0010] As a further configuration of the above solution, a handle is provided on the base frame at a side away from the sweeping and collecting head.

[0011] As a further configuration of the above scheme, the sweeping and collecting head includes a sweeping barrel fixedly connected to the lower end portions of the two inclined side plates, and the lower end of the sweeping barrel is open, a sweeping shaft is rotatably installed in the sweeping barrel, one end of the sweeping shaft is connected to a second motor, and a plurality of brush members are evenly arranged on the outer cylindrical surface of the sweeping shaft.

[0012] During use of the seed drying turning and recovery device disclosed in the present invention, when it is necessary to turn the seeds laid on the ground up and down, the first motor and the second motor are started, and under the action of the first motor, the sweeping and collecting head will sweep the seeds toward the conveying device and enter the lower end of the conveying device through the loading plate, and the second motor drives the conveyor belt to rotate clockwise, and then under the action of the scraper, the seeds move along the bottom wall of the conveying box, and when they move to the discharge port, they are discharged by the discharge inclined plate and laid on the ground again, completing the up and down turning of the seeds.

[0014] In addition, when the seeds are recovered and transported along the upper part of the conveyor box, whenever the seeds move to the position of the suction chamber shell, the cam is pressed down and the movable bar slides off. Then, under the action of the elastic restoring force of the spring, the movable bar will instantly push up and act on the conveyor belt, thereby knocking the seeds on the conveyor belt into the suction chamber shell, and the negative pressure suction inside the dust extraction pipe can suck out the dust mixed in the seed population, effectively removing dust impurities. The seeds after suction and dust removal fall onto the conveyor belt and are transported from the conveyor belt to the collection box, completing the seed recovery and dust removal operation.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: During use, the seed drying turning and recovery device disclosed in the present invention controls the conveyor belt to rotate clockwise and counterclockwise, and then cooperates with the guide switching mechanism and the scraper to realize the seeds being transported along the bottom or upper part of the conveyor box.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 8 , and describes the application in detail with reference to embodiments. Example 1

[0021] Example 1 discloses a device for turning and recycling seeds during drying.

[0022] A group of vertical poles 104 of different heights are arranged on both the front and rear sides of the upper surface of the base frame 101 , and the same group of vertical poles 104 are designed to gradually become lower from one side of the handle 103 to the other side, and then an inclined side plate 105 is fixedly connected to the top of each group of vertical poles 104 .

[0023] The sweeping and collecting head 2 includes a sweeping barrel 201 fixedly connected to the lower ends of the two inclined side plates 105. The lower end of the sweeping barrel 201 is open, and a sweeping shaft 202 is concentrically arranged inside the sweeping barrel 201. One end of the sweeping shaft 202 extends out of the side end of the sweeping barrel 201 and is connected to the first motor 203 on the inclined side plate 105, and then a plurality of brushes 204 are evenly installed on the outer circumferential surface of the sweeping shaft 202. During the forward movement of the mobile frame 1, the sweeping shaft 202 is driven by the first motor 203 to rotate at a set speed, and then the seeds laid on the ground are swept to one side of the mobile frame 1 under the action of the brush 204.

[0024] Reference Figure 4 and attached Figure 5The conveying device 3 includes a conveying box 301 which is fixedly arranged between two inclined side plates 105, and the upper and lower ends of the conveying box 301 are both open, and the bottom wall of the lower end opening of the conveying box 301 extends downward with a loading plate 302, so that the seeds swept up by the sweeping and collecting head 2 can enter the lower end opening of the conveying box 301 through the loading plate 302. Conveying rollers 303 are arranged at the upper and lower openings of the conveying box 301, wherein the upper conveying roller 303 is connected to the second motor 304 on the inclined side plate 105 as a power input end, and then a conveying belt 305 is arranged between the upper and lower conveying rollers 303, and a plurality of scrapers 306 are arranged at equal intervals on the outer surface of the conveying belt 305, and a gap of about 2 to 5 mm is left between the upper and lower rows of scrapers 306 and the upper and lower inner walls of the conveying box 301, so that the scrapers 306 can move smoothly in the conveying box 301 under the action of the conveying belt 305, and ensure that the seeds will not leak.

[0025] A discharge port is provided on the lower surface of the conveying box 301, and a discharge inclined plate 307 inclined downward is provided on the discharge port. When the conveyor belt 305 rotates clockwise, the swept seeds can be conveyed along the bottom wall of the conveying box 301 through the scraper 306, and then the seeds are re-discharged through the discharge port and the discharge inclined plate 307, so that the seeds are turned over and laid on the ground again.

[0026] The collection box 4 is arranged on the mobile frame 1 near the handle 103, and the upper opening of the collection box 4 is opposite to the upper opening of the conveying box 301, so that when the conveying belt 305 rotates counterclockwise, the swept seeds can be conveyed along the upper part of the conveying box 301 by the scraper 306, and then fall from the upper opening of the conveying box 301 into the collection box 4, completing the seed collection process. In addition, in order to facilitate the subsequent removal of the seeds in the collection box 4, a discharge port is also opened at the lower end of the collection box 4, and a sealing door 401 is provided on the discharge port.

[0027] Reference Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 6 and attached Figure 7 A guide switching mechanism 5 is arranged between the conveying device 3 and the sweeping and collecting head 2. The specific guide switching mechanism 5 includes a hollow shaft 501 which is rotatably connected to the lower ends of the two inclined side plates 105 through a torsion spring 503, and a tooth surface inner disk 502 is concentrically connected to the end of the hollow shaft 501. A fan-shaped plate 504 is fixedly connected to the outer circular surface of the tooth surface inner disk 502, and then an arc-shaped guide plate 505 which is concentrically arranged with the lower conveying roller 303 is fixedly connected between the outer circular ends of the two fan-shaped plates 504, and the arc-shaped guide plate 505 is tangent to the upper surface of the loading plate 302 when rotating downward.

[0028] The roller shafts at both ends of the lower conveying roller 303 are connected to one-way transmission devices 506, and the one-way transmission devices 506 are connected to notched gears 507 extending into the inner tooth surface disk 502. An arc-shaped opening 5021 is concentrically provided on the inner wall of the tooth surface inner disk 502, and an intermediate gear 508 is provided between the notched gear 507 and the tooth surface inner disk 502. The intermediate gear 508 is provided with a gear shaft 509 connected to the lower end of the oblique side plate 105 through the arc-shaped opening 5021.

[0029] Through the design of the guide switching mechanism 5 in this embodiment, when the conveyor belt 305 rotates clockwise, the one-way transmission device 506 cannot transmit the transmission force to the notched gear 507. At this time, there is a certain gap between the arc-shaped guide plate 505 and the loading plate 302 under the action of the torsion spring, and the grain fed by the sweeping and collecting head 2 can enter the lower end of the conveying box 301 through the loading plate 302. Then, when the conveyor belt 305 rotates clockwise, the scraper 306 can transport the swept seeds along the bottom wall of the conveying box 301, and then the seeds are re-discharged through the discharge port and the discharge inclined plate 307, so that the seeds are turned over and laid on the ground again, completing the seed turning process up and down.

[0030] When the conveyor belt 305 rotates counterclockwise, the transmission force can be transmitted to the notched gear 507 through the one-way transmission device 506. At this time, under the action of the notched gear 507, the intermediate gear 508 and the tooth surface inner disk 502, the arc guide plate 505 will rotate downward until it is connected with the unloading inclined plate 307. At this time, the grain entering the lower end of the conveying box 301 enters the upper part of the conveying box 301 for transportation under the action of the arc guide plate 505 and the scraper 306, and then falls from the upper end opening of the conveying box 301 to the collecting box 4, completing the seed collection process. And every time the conveyor belt 305 rotates counterclockwise for a certain distance, the notched gear 507 will slip off the intermediate gear 508, and the arc-shaped guide plate 505 will instantly rotate upward under the action of the torsion spring 503 and open the feeding gap between it and the unloading inclined plate 307, so that the next part of seeds can smoothly enter the lower end of the conveying box 301, and the counterclockwise conveyance of the grain will be completed after the arc-shaped guide plate 505 rotates downward again, thereby completing the collection of the seeds after drying. Example 2

[0031] Example 2 discloses a seed drying turning and recovery device that is improved and designed based on the technical solution in Example 1, and its similarities with Example 1 will not be described again.

[0032] Reference Figure 4 , Attachment Figure 5 and attached Figure 7In this embodiment 2, a dust collecting mechanism 6 is provided on the conveying device 3, and the dust collecting mechanism includes a dust collecting fan 601 and a filter box 602 installed on the lower surface of the conveying box 301 or the bottom frame 101, and the dust collecting fan 601 is connected to one end of the filter box 602, and then a dust collecting pipe 603 is connected to the other end of the filter box 602. At the same time, an upwardly protruding suction chamber shell 604 is provided on the upper surface of the conveying box 301, and the dust collecting pipe 603 is connected to the lower side of the suction chamber shell 604.

[0033] In addition, the dust collecting mechanism 6 also includes a fixed bar 605 fixed inside the conveying box 301, and a movable bar 606 is arranged below the fixed bar 605. A row of bumping heads 607 are arranged on the movable bar 606, and a row of guide holes for passing the bumping heads 607 are opened on the fixed bar 605, and the bumping heads 607 are arranged toward the inner surface of the conveying belt 305 at the position of the suction chamber shell 604. A plurality of springs 608 are connected between the fixed bar 605 and the movable bar 606, and a rotating shaft 609 is rotatably arranged beside the movable bar 606, and a pressing cam 610 acting on the movable bar 606 is arranged on the rotating shaft 609. A first pulley 611 is arranged at the end of the rotating shaft 609 extending out of the conveying box 301, and then a second pulley 612 is arranged on the roller shaft of the upper conveying roller 303, and finally a transmission belt 613 is arranged between the first pulley 611 and the second pulley 612.

[0034] The dust suction mechanism 6 in this embodiment 2 is started during the seed recovery process. When the seeds move to the suction chamber shell 604 with the conveyor belt 305, the cam 610 is pressed down and the movable bar 606 slips off. Then, under the action of the elastic restoring force of the spring 608, the movable bar 606 is instantly pushed up and acts on the conveyor belt 305, thereby knocking the seeds on the conveyor belt 305 into the suction chamber shell 604, and the negative pressure suction effect inside the dust suction pipe 603 can suck the dust mixed in the seed population, effectively removing dust impurities. The seeds after suction and dust removal fall onto the conveyor belt 305 again, and are transported to the collection box 4 from the conveyor belt 305.
