Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a raw grain destoner for rice processing. Background Technology

[0002] Rice processing refers to the process of transforming paddy rice into rice products that can be directly consumed by humans or further processed through a series of procedures. This process includes cleaning, hulling, milling, grading, and packaging, and involves the entire industrial chain from farm to table, including multiple stages such as rice planting, purchasing, storage, processing, and sales.

[0003] Patent CN210357979U discloses a raw grain destone removal device for rice processing. It includes a feeding cylinder, which is trapezoidal in shape, and a storage cavity is bolted to one end of the feeding cylinder. The storage cavity is hollow. A motor is installed on one side of the storage cavity, and a cylindrical rotating rod is connected to the other side of the motor via a coupling. The device has a mesh-like filter plate, and a hollow collection cavity is provided at the bottom of the filter plate. In this way, after the filter plate separates the rice from the stones, the collection cavity at the bottom of the filter plate can effectively store the rice, thereby improving the efficiency of rice use in the later stages.

[0004] However, this device only has a single filter plate for screening. When rice containing stones is poured into the storage chamber, the filter plate can only filter the rice once, which is insufficient to completely remove the stones. Therefore, screening needs to continue. At the same time, the screened rice will slide into the collection chamber, which is located inside the storage chamber. This means that after a certain period of screening, the device must be stopped, the collection chamber removed, the rice poured out, and then refilled before the screening and stone removal process can continue. The combination of these two situations seriously affects the efficiency of rice stone removal. To address this issue, a raw grain stone removal device for rice processing is proposed to solve the problem that existing raw grain stone removal devices cannot continuously and quickly remove stones from raw grains.

[0006] To address the shortcomings of existing technologies, this utility model provides a raw grain destoning device for rice processing, which solves the aforementioned problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a raw grain destoning device for rice processing, comprising a base plate, a screen frame on the top of the base plate, a conveyor belt inside the screen frame, a collection box on one side of the top of the base plate, a screen box on the top of the collection box, a plurality of screen grooves and a second screen groove being respectively opened through the surface of the conveyor belt and the bottom of the inner cavity of the screen box, three scrapers being provided on the top of the conveyor belt, the scrapers being connected by connecting rods, a drive plate and two symmetrically arranged electric push rods being provided at both ends of the screen frame, a feeding mechanism being provided on one side of the screen frame, the drive plate being connected to the screen box by a connecting mechanism, and a slot being opened through the bottom of the screen frame.

[0009] Preferably, the top surface of the collection box and the bottom surface of the sieve box are both very smooth, the sieve groove can filter out small stones, and the second sieve groove only allows rice to pass through.

[0010] Preferably, the connecting rod passes through the screen frame and is slidably connected, the connecting rod is fixedly connected to the drive plate, the two ends of the electric push rod are fixedly connected to the screen frame and the drive plate respectively, and the bottom of the scraper is in contact with the top of the conveyor belt.

[0011] Preferably, the feeding mechanism includes a feeding seat fixedly connected to the top of one side of the inner cavity of the screen frame, and there is a certain gap between the bottom of the feeding seat and the conveyor belt.

[0012] Preferably, the top of the feeding seat is provided with a conical groove, and the bottom of the conical groove is provided with a feeding slot, which communicates with the inner cavity of the screen frame.

[0013] Preferably, the connecting mechanism includes connecting slots that extend through both ends of the screen box of the drive plate, a connecting plate is provided inside the connecting slots, a control plate is fixedly connected to one end of the connecting plate, and a groove is provided on the top of the control plate.

[0014] Preferably, a limiting groove is formed at the bottom of the base plate, and a roller is provided in the inner cavity of the limiting groove, and the roller is fixedly connected to the collection box.

[0015] (III) Beneficial Effects

[0016] 1. This raw grain destone removal device for rice processing uses an electric push rod, connecting rod, and drive plate, along with a scraper, to scrape the raw grain on the conveyor belt back and forth during the conveyor belt process. This causes smaller stones to pass through the sieve trough and be discharged from the trough opening. At the same time, the raw grain continues to be conveyed to the right side to the sieve box, where the drive plate moves back and forth to discharge the raw grain from the second sieve trough. Larger stones remain in the sieve box, solving the problem that existing raw grain destone removal devices are unable to continuously and quickly remove stones from the raw grain.

[0017] 2. In this rice processing raw grain destone removal device, after a large number of large stones accumulate in the sieve box, the connecting plate can be removed from the connecting slots at both ends of the drive plate and the sieve box by using the pull groove on the control panel. This allows the drive plate to be separated from the sieve box, and the sieve box can be moved out from the top of the collection box to clean the stones inside, which is convenient for subsequent raw grain screening and stone removal.

[0025] Furthermore, the top surface of the collection box 4 and the bottom surface of the sieve box 5 are both very smooth, the sieve 6 can filter out smaller stones, and the second sieve 7 only allows rice to pass through.

[0026] Furthermore, the connecting rod 9 passes through the screen frame 2 and is slidably connected. The connecting rod 9 is fixedly connected to the drive plate 10. The two ends of the electric push rod 11 are fixedly connected to the screen frame 2 and the drive plate 10 respectively. The bottom of the scraper 8 is in contact with the top of the conveyor belt 3.

[0027] Furthermore, the feeding mechanism 12 includes a feeding seat 121 fixedly connected to the top of one side of the inner cavity of the screen frame 2, and there is a certain gap between the bottom of the feeding seat 121 and the conveyor belt 3.

[0028] Furthermore, a conical groove 122 is provided at the top of the feeding seat 121, and a feeding trough 123 is provided through the bottom of the conical groove 122. The feeding trough 123 is connected to the inner cavity of the screen frame 2. The raw grain for destone removal can be introduced into the conical groove 122 in the feeding seat 121. With the help of the feeding trough 123, the raw grain falls into the top of the conveyor belt 3 for conveying and screening. Raw grain can also be added during the screening and destone removal process to ensure the continuity of screening and destone removal.

[0029] Furthermore, the connecting mechanism 13 includes connecting slots 131 that pass through both ends of the sieve box 5 on the drive plate 10. A connecting plate 132 is provided inside the connecting slots 131. A control plate 133 is fixedly connected to one end of the connecting plate 132.

The external drive device, together with the conveyor belt 3, transports the raw grain to the right. During the process, the electric push rod 11 drives the drive plate 10 and the connecting rod 9 to move back and forth. With the help of the scraper 8, the raw grain on the conveyor belt 3 is scraped back and forth, so that smaller stones are discharged from the screen trough 6 through the slot 16. Then the raw grain continues to be conveyed into the screen box 5. With the cooperation of the drive plate 10, the screen box 5 also moves back and forth, so that the raw grain is discharged from the second screen trough 7 and enters the collection box 4. Larger stones remain in the screen box 5. This solves the problem that existing raw grain destoners cannot continuously and quickly remove stones from the raw grain.
