Description

Technical Field

[0001] This invention relates to the field of flour production technology, and in particular to a wheat washing and pounding integrated cleaning machine for flour production. Background Technology

[0002] During the wheat production and drying process, wheat straw, dust, and pest-damaged grains often become mixed in with the wheat. Wheat straw, due to its high moisture content and hard outer layer, is difficult to remove; dust, mainly composed of various ground particles and airborne suspended particles, is numerous despite its small size and easily adheres to the wheat surface; pest-damaged grains, due to insect infestation, are prone to developing holes or discoloration. All these factors can affect the quality of subsequent wheat flour production. Therefore, before milling, a wheat washing and milling integrated cleaning machine is needed to clean the wheat to ensure product quality and hygiene safety during subsequent processing.

[0003] A wheat washing and pounding integrated cleaning machine for flour production, with announcement number CN117160977B, has solved the technical drawback of inconvenience in effectively separating and removing some impurities and diseased wheat grains contained inside the wheat, thus affecting the overall use effect of the equipment. However, in actual use, similar structures still have many defects. For example, existing cleaning machines fail to remove impurities from the washing tank in time, and impurities are re-mixed into the wheat flow when draining, which affects the washing effect of wheat and subsequent processing.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, this invention proposes a wheat washing and smelting integrated cleaning machine for flour production, which solves the problem that if impurities are not removed from the washing tank in time, they will be re-mixed into the wheat stream during drainage, affecting the washing effect and subsequent processing of wheat.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows: A wheat washing and threshing integrated cleaning machine for flour production includes a water tank, a washing box, a spin dryer, a scooping mechanism, and a threshing machine. It also includes a drive mechanism fixedly installed on the top of the threshing machine. An air separation mechanism is fixedly installed on the top of the threshing machine away from the drive mechanism, and an air duct is fixedly installed at the output end of the air separation mechanism, with the air outlet extending into the interior of the threshing machine. A feeding mechanism is installed through the top of the threshing machine near the air separation mechanism, and a filter cover is fixedly installed on one side of the threshing machine.

A wheat discharge hopper is installed through one side of the bottom of the threshing machine. The output end of the drive mechanism is connected to the screening drum via gear transmission, so that wheat conveying and screening are carried out simultaneously. During operation, wheat enters the threshing machine through the feeding mechanism. The wind separation mechanism outputs air force to wind separate the evenly fed wheat. The wind-separated wheat straw falls into the filter cover. The wind-separated wheat enters the screening drum. The screening drum rotates to break up and remove impurities and gravel. The wheat that has been cleaned is then sent to the washing tank through the wheat discharge hopper for washing. The retrieval mechanism is fixedly installed on one side of the top of the cleaning tank. The retrieval mechanism consists of a filter box, a servo motor, a retrieval valve plate, a reciprocating transmission assembly, and a gear transmission assembly.

One end of the retrieval valve plate is connected to one end of the reciprocating transmission assembly, and the other end of the retrieval valve plate is connected to the output end of the servo motor via a transmission rod. The servo motor is fixedly installed on the top of the cleaning tank via a mounting plate. A servo motor drives a retrieval valve plate to rotate, which retrieves impurities generated during wheat washing inside the washing tank and transports them to the filter tank for draining. Simultaneously, the rotating retrieval valve plate drives a reciprocating transmission assembly, which in turn drives a gear transmission assembly. This gear transmission assembly then drives a cleaning scraper to move back and forth, cleaning impurities inside the filter tank to the door. The gear transmission assembly, through its gear mechanism, drives the door to open and close, allowing impurities to be discharged from the filter tank through the open door, thus achieving the purpose of impurity collection and cleaning.

[0007] Preferably, the reciprocating transmission assembly consists of a slide plate, a rack plate, two slide frames, and a lever. The two slide frames are fixedly installed on both sides of the top of the filter box. The rack plate is movably installed inside the slide frame. The slide plate is fixedly installed at one end of the rack plate.

[0009] Preferably, the screening drum consists of an impurity screen cylinder, a wheat screen cylinder, a feeding plate, a feed hopper, a crushed stone discharge hopper, and a rotating gear. One end of the impurity screen cylinder is connected to one end of the wheat screen cylinder, and the rotating gear is fixedly sleeved at the connection between the impurity screen cylinder and the wheat screen cylinder. Feeding plates are arranged in a circular array on the inner walls of both the impurity screen cylinder and the wheat screen cylinder. One end of the feed hopper is rotatably installed at the other end of the impurity screen cylinder, and the other end of the feed hopper is fixedly installed on the inner wall of the threshing machine. One end of the crushed stone discharge hopper is rotatably installed at the other end of the wheat screen cylinder, and the other end of the crushed stone discharge hopper is fixedly installed on the inner wall of the threshing machine.

[0010] Preferably, an impurity discharge hopper is installed through the bottom of the threshing machine on the other side, and a crushed stone discharge hopper is fixedly installed on the other side of the threshing machine. The three partition plates inside the threshing machine divide the interior of the threshing machine into four spaces, namely, an air separation chamber, an impurity screening chamber, a wheat screening chamber, and a crushed stone screening chamber.

[0011] Preferably, a cleaning pipe is fixedly installed at the top inside the spin dryer, and high-pressure nozzles are installed at equal intervals at the bottom of the cleaning pipe.

[0013] Preferably, the interior of the cleaning tank is divided into a cleaning chamber and a water guiding chamber by a partition. The auger assembly is rotatably installed inside the cleaning chamber. The operation of the auger assembly disturbs the water source to generate water flow and achieve uniform cleaning.

[0014] Preferably, the drive mechanism consists of a drive motor and a drive gear. The drive motor is fixedly installed on the top of the threshing machine, one side of the drive gear is fixedly connected to the output end of the drive motor via a shaft, and the bottom of the drive gear extends into the interior of the threshing machine and meshes with the rotating gear.

[0015] The beneficial effects of this invention are: The technical solution of this invention uses a servo motor to drive a retrieval valve plate to rotate. The rotating valve plate retrieves impurities generated during wheat washing inside the washing tank and transports them to the filter tank for drainage, reducing water waste. Simultaneously, the rotating valve plate drives a reciprocating transmission assembly, which in turn drives a gear transmission assembly. This gear transmission assembly drives a cleaning scraper to move back and forth, cleaning impurities inside the filter tank to the door, preventing accumulation and maintaining good drainage and efficient impurity removal. The gear transmission assembly also drives the door to open and close, allowing impurities to be discharged through the open door. This achieves efficient impurity retrieval, drainage, automatic cleaning, and timely discharge, ensuring the efficiency and continuity of impurity retrieval during wheat washing. It also enables the recycling of water for impurity removal, solving the technical problem of untimely impurity removal affecting washing results, improving the continuity and efficiency of the washing process, and achieving efficient and high-quality wheat washing.

[0018] The following will be combined with the appendix Figure 1 To be continued Figure 11 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] A wheat washing and threshing integrated cleaning machine for flour production includes a water tank 1, a washing box 2, a spin dryer 3, a scooping mechanism 4, and a wheat threshing machine 5. It also includes a drive mechanism 9 fixedly installed on the top of the wheat threshing machine 5. The output end of the drive mechanism 9 extends into the inside of the wheat threshing machine 5 and provides driving force to the screening drum 501. A wind classifier 8 is fixedly installed on the top side of the threshing machine 5 away from the drive mechanism 9, and an air duct is fixedly installed at the output end of the wind classifier 8. The air outlet of the air duct extends into the interior of the threshing machine 5. A feeding mechanism 6 is installed through the top side of the threshing machine 5 near the wind classifier 8. The feeding mechanism 6 evenly conveys wheat into the interior of the threshing machine 5. At the same time, the wind classifier 8 is started and powered on to generate wind. The wind force performs wind classification on the wheat conveyed by the feeding mechanism 6 to remove the lighter wheat straw and impurities. The removed wheat straw and impurities fall into the filter cover 7 for collection, while the wind-classified wheat falls into the screening drum 501. A filter cover 7 is fixedly installed on one side of the wheat threshing machine 5. A collection box is threaded on the bottom of the filter cover 7, which is easy to remove and clean the collected wheat straw. An air duct is installed on the top of the filter cover 7 through a filter bag. The air duct extends into the washing tank 2 through a one-way valve to aerate the water flow inside the washing tank 2 and improve the washing effect of the water flow on the wheat. The washing tank 2 is fixedly installed inside the water tank 1. The interior of the washing tank 2 is divided into a washing chamber and a water guiding chamber by a partition. The auger assembly 201 is rotatably installed inside the washing chamber. The auger assembly 201 rolls and works with the water flow to achieve uniform washing and avoid agitation that could damage the wheat grains. The bottom end of the spin dryer 3 is connected to one end of the washing tank 2. The washing tank 2 uses the auger assembly 201 to roll and work with the water flow to achieve uniform washing of the wheat. The wheat enters the spin dryer 3 under the drive of the water flow and is spun dry by the spin dryer 3. The threshing machine 5 is fixedly installed on the top of the water tank 1. Inside the threshing machine 5, a screening roller 501 is rotatably installed through three partition plates 505. A wheat discharge hopper 503 is installed through one side of the bottom of the threshing machine 5. The output end of the drive mechanism 9 is connected to the screening roller 501 through gear transmission, so that wheat conveying and screening are carried out simultaneously. During operation, wheat enters the threshing machine 5 through the feeding mechanism 6. The wind separation mechanism 8 outputs wind force to perform wind separation on the uniformly fed wheat. The wind-separated wheat straw falls into the filter cover 7. The wind-separated wheat enters the screening roller 501. The screening roller 501 rotates to break up and remove impurities and gravel. Then, the wheat that has been cleaned is sent to the washing box 2 through the wheat discharge hopper 503 for washing, which effectively improves the cleaning efficiency and flour quality. This equipment, through the integrated washing and threshing structure, greatly shortens the process flow, reduces energy consumption and floor space, and avoids the loss and pollution caused by material transfer. It is suitable for the continuous operation needs of modern flour production lines. The retrieval mechanism 4 is fixedly installed on one side of the top of the cleaning tank 2. The retrieval mechanism 4 consists of a filter box 401, a servo motor 402, a retrieval valve plate 403, a reciprocating transmission assembly 404, and a gear transmission assembly 405. The retrieval valve plate 403 extends into the water guiding chamber. The filter box 401 is fixedly installed on one side of the top of the cleaning tank 2, and one end of the filter box 401 extends through to one side of the water tank 1. A cleaning scraper 4011 is movably installed inside the filter box 401. A door 4012 is movably installed on the front of the filter box 401 through a sliding groove. A toothed conditioner 4013 is fixedly installed on the top of the door 4012. The reciprocating transmission assembly 404 is fixedly installed on the top of the filter box 401. The gear transmission assembly 405 is mounted on the filter box 401 through the bearing seat. One end of the gear transmission assembly 405 is connected to the reciprocating transmission assembly 404 and the gear condition 4013 respectively. The bottom of the gear transmission assembly 405 is connected to the cleaning scraper 4011. One end of the retrieval valve plate 403 is connected to one end of the reciprocating transmission assembly 404. The other end of the retrieval valve plate 403 is connected to the output end of the servo motor 402 through the transmission rod. The servo motor 402 is fixedly installed on the top of the cleaning box 2 through the mounting plate. The reciprocating transmission assembly 404 consists of a slide plate 4041, a rack plate 4042, two slide frames 4043, and a lever 4044. The two slide frames 4043 are fixedly installed on both sides of the top of the filter box 401. The rack plate 4042 is movably installed inside the slide frame 4043. The slide plate 4041 is fixedly installed at one end of the rack plate 4042. One end of the lever 4044 is movably connected to the slide groove inside the slide plate 4041, and the other end of the lever 4044 is splinedly connected to one end of the retrieval valve plate 403 via a splined rod. The reciprocating transmission assembly 404 ensures that the cleaning scraper 4011 and the door 4012 can perform cleaning and opening / closing operations according to a predetermined route, thereby cleaning the impurities inside the filter box 401 and ensuring the drainage of the filter box 401. The gear transmission assembly 405 consists of a lead screw 4051, a lead sleeve frame 4052, a first gear 4053, and a second gear 4054. The lead screw 4051 is mounted on the top of the filter box 401 via a bearing seat. The lead sleeve frame 4052 is sleeved on the outside of the lead screw 4051 and is fixedly connected to the top of the cleaning scraper 4011 via a bearing seat. The first gear 4053 is sleeved on one end of the lead screw 4051 and meshes with the rack plate 4042. The second gear 4054 is fixedly mounted on one end of the lead screw 4051 and meshes with the rack plate 4013. The servo motor 402 drives the retrieval valve plate 403 to rotate. The rotating retrieval valve plate 403 retrieves the impurities generated during the washing of wheat inside the washing box 2 and transports them to the filter box 401 for drainage. At the same time, the rotating retrieval valve plate 403 drives the reciprocating transmission assembly 404 to run. The running reciprocating transmission assembly 404 drives the gear transmission assembly 405 to run. The running gear transmission assembly 405 drives the cleaning scraper 4011 to move back and forth, cleaning the impurities inside the filter box 401 to the box door 4012. Meanwhile, the running gear transmission assembly 405 drives the box door 4012 to open and close through the gear condition 4013. The impurities are discharged from the filter box 401 through the open box door 4012, achieving the purpose of collecting and cleaning impurities, avoiding local accumulation of impurities, and ensuring the drainage effect of the filter box 401. It should be noted that when the salvage mechanism 4 is working, the servo motor 402 is powered on and drives the salvage valve plate 403 to rotate. The rotating salvage valve plate 403 salvages and cleans the impurities and floating objects generated by the wheat in the water guiding chamber of the cleaning tank 2, and transports the impurities and floating objects to the filter box 401 for drainage treatment. At the same time, the rotating salvage valve plate 403 drives the reciprocating transmission assembly 404 to run. Specifically, the salvage valve plate 403 drives the actuating rod 4044 to rotate. The rotating actuating rod 4044 drives the rack plate 4042 to move horizontally and reciprocally through the sliding groove inside the sliding plate 4041. The horizontally reciprocating rack plate 4042 drives the cleaning scraper 4011 and the filter box 4012 to reciprocate through the gear transmission assembly 405. Specifically, the first gear 4053, which meshes with the horizontally reciprocating rack plate 4042, drives the lead screw 4051 to rotate in both directions. The rotating lead screw 4051 converts the rotational force into linear movement through the lead sleeve frame 4052, driving the cleaning scraper 4011 to reciprocate inside the filter box 401, pushing and cleaning the impurities drained inside the filter box 401. At the same time, the rotating lead screw 4051, through the second gear 4054 at one end, meshes with the gear 4013 to drive the filter box 4012 to reciprocate, realizing the purpose of opening or closing the filter box 401. When the cleaning scraper 4011 passes through the filter box 4012, the cleaning scraper 4011 moves back and forth. When impurities in filter box 401 are pushed to the door 4012, the door 4012 is in the open state, facilitating the discharge of the cleaned impurities from filter box 401 through the open door 4012. When the cleaning scraper 4011 moves away from the maximum distance from the door 4012, the door 4012 returns to the closed state, ensuring the airtightness of the internal environment of filter box 401. At this time, the retrieval valve plate 403 transports the retrieved impurities into the filter box 401. The closed filter box 401 effectively drains the impurities. Repeating the above actions achieves the purpose of continuous collection and cleaning of impurities, avoiding the problem of impurities being re-mixed into the wheat flow during drainage, which would affect the cleaning effect. This ensures the cleaning effect of the water source and allows for repeated use, not only improving cleaning efficiency but also guaranteeing the high quality of the cleaned wheat.

[0020] like Figures 4 to 5 As shown, the screening drum 501 consists of an impurity screen cylinder 5011, a wheat screen cylinder 5012, a feed plate 5013, a feed hopper 5014, a crushed stone discharge hopper 5015, and a rotating gear 5016. One end of the impurity screen cylinder 5011 is connected to one end of the wheat screen cylinder 5012, and the rotating gear 5016 is fixedly sleeved at the connection between the impurity screen cylinder 5011 and the wheat screen cylinder 5012. The feed plates 5013 are arranged in a circular array on the inner walls of both the impurity screen cylinder 5011 and the wheat screen cylinder 5012. One end of the feed hopper 5014 is rotatably mounted on the impurity screen cylinder 5011. At the other end of 1, and at the other end of the feed hopper 5014, it is fixedly installed on the inner wall of the threshing machine 5. At one end of the crushed stone discharge hopper 5015, it is rotatably installed on the other end of the wheat sieve cylinder 5012. At the other end of the crushed stone discharge hopper 5015, it is fixedly installed on the inner wall of the threshing machine 5. At the other side of the bottom of the threshing machine 5, an impurity discharge hopper 502 is installed through. At the other side of the threshing machine 5, a crushed stone discharge hopper 504 is fixedly installed. The three partition plates 505 inside the threshing machine 5 divide the inside of the threshing machine 5 into four spaces, which are, in order, the air separation chamber, the impurity screening chamber, the wheat screening chamber, and the crushed stone screening chamber. It should be noted that the air ducts of the feed hopper 5014, the discharge end of the feeding mechanism 6, and the output end of the air separation mechanism 8 are located in the air separation chamber; the impurity screen cylinder 5011 is located in the impurity screening chamber, and the impurity discharge hopper 502 is located below the impurity screening chamber, so the impurities and broken wheat screened by the impurity screen cylinder 5011 are discharged through the impurity discharge hopper 502; the wheat screen cylinder 5012 is located in the wheat screening chamber, and the wheat discharge hopper 503 is located below the wheat screening chamber, so the compliant wheat screened by the wheat screen cylinder 5012 is discharged through the wheat discharge hopper 503; After being separated by air separation mechanism 8, the wheat, affected by weight, falls into feed hopper 5014. The inclined feed hopper 5014 conveys the wheat to impurity screen cylinder 5011. The rotating impurity screen cylinder 5011 disperses the wheat while pushing it forward through the material-pulling plate 5013. The rotating impurity screen cylinder 5011 removes impurities and broken wheat from the wheat. The removed impurities and broken wheat are discharged through impurity discharge hopper 502. After screening, the wheat is conveyed to the wheat sieve cylinder 5012 by the rotating material feeding plate 5013. The qualified wheat is screened out by the rotating material feeding plate 5013 and the wheat sieve cylinder 5012, and then conveyed to the washing chamber in the washing box 2 through the wheat discharge hopper 503. Under the action of the auger assembly 201, the floating wheat is washed and pushed by the water flow.

[0021] like Figure 7 As shown, a cleaning pipe 301 is fixedly installed on the top of the inside of the spin dryer 3, and high-pressure nozzles are installed at equal intervals on the bottom of the cleaning pipe 301. It should be noted that the water source transported by the water pipe 102 is evenly distributed through the cleaning pipe 301, and the water source is sprayed out at high pressure through the equally spaced high-pressure nozzles to wash the inner wall of the spin dryer 3 and the filter screen, so as to achieve the purpose of self-cleaning. The wastewater generated by washing the spin dryer 3 and the wastewater generated by spinning wheat flow into the filter chamber set between the water tank 1 and the cleaning box 2.

[0022] like Figures 6 to 7 As shown, a filter chamber is provided between the water tank 1 and the cleaning tank 2, and filter plates 103 are installed at equal intervals in the filter chamber; a circulation pump 101 is fixedly installed on one side of the water tank 1, and a water pipe 102 is fixedly installed at the output end of the circulation pump 101. One end of the water pipe 102 extends into the water guide chamber inside the cleaning tank 2, and the other end of the cleaning tank 2 extends into the interior of the spin dryer 3 and is connected to the cleaning pipe 301; a valve pipe extending into the filter chamber is fixedly installed at the input end of the circulation pump 101. It should be noted that sedimentation is carried out in the filter chamber, and the wastewater is filtered by the filter plates 103 installed at equal intervals in the filter chamber. The circulating pump 101 operates to draw the filtered water through the valve pipe and deliver it to the water pipe 102. As needed, the water is transferred to the water guide chamber or the cleaning pipe 301 inside the cleaning tank 2, thus realizing the recycling of the water source.

[0023] like Figure 5 As shown, the drive mechanism 9 consists of a drive motor 901 and a drive gear 902. The drive motor 901 is fixedly installed on the top of the wheat threshing machine 5. One side of the drive gear 902 is fixedly connected to the output end of the drive motor 901 through a shaft. The bottom of the drive gear 902 extends into the interior of the wheat threshing machine 5 and meshes with the rotating gear 5016. It should be noted that a protective cover is fixedly installed on the outside of the drive gear 902. The protective cover protects the drive gear 902 from damage by external objects or forces. When the drive motor 901 is powered on, it drives the drive gear 902 to rotate. The rotating drive gear 902 drives the impurity sieve cylinder 5011 and the wheat sieve cylinder 5012 to rotate synchronously through the meshing rotating gear 5016, providing driving force for screening wheat.
