Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rice sieve feeding structure, specifically a feeding structure based on rice sieve machinery used in rice production. Background Technology
[0002] Rice production is the process of removing the husk and bran from paddy rice. Paddy rice consists of the husk, bran, germ, and endosperm. After the husk and bran are removed, a rice sieving device is used to screen out the small husks and broken rice. However, a feeding structure is needed to add the rice into the rice sieving machine during the screening process.
[0003] Most rice screening machines currently use a feeding hourglass to feed the rice, which flows into the screening device by its own weight. However, this method may result in excessive feeding, causing too much rice to be on the screening screen, resulting in some rice not being screened and thus affecting the screening effect. Utility Model Content
[0004] The purpose of this invention is to provide a feeding structure for rice screening machinery used in rice production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding structure for a rice sieve in rice production, comprising: a feeding hourglass; a supporting base plate fixedly connected inside the feeding hourglass; a metering frame slidably connected to the supporting base plate; a cylinder mounted on the feeding hourglass, with the telescopic end of the cylinder fixedly connected to one side of the metering frame; a connecting plate fixedly connected to the cylinder; and a filter screen installed inside the feeding hourglass; the metering frame and the supporting base plate are configured to cooperate in feeding rice quantitatively within the feeding hourglass.
[0006] As a further preferred embodiment of this technical solution, it also includes: a scraper, installed inside the feeding hourglass.
[0007] As a further preferred embodiment of this technical solution, it also includes: a reinforcing rib, which is fixedly connected to the connecting plate, and one end of the reinforcing rib is fixedly connected to one side of the quantitative frame.
[0008] As a further preferred embodiment of this technical solution, it also includes: a storage box, which is slidably connected inside the feeding hourglass and is located below the filter screen; and a baffle, which is fixedly connected inside the feeding hourglass.
[0009] As a further preferred embodiment of this technical solution, it also includes: a mounting ear, fixedly connected to the feeding hourglass; and a fixing rod, slidably connected inside the mounting ear.
[0010] As a further preferred embodiment of this technical solution, it also includes: a rotating mechanism, installed on the feeding hourglass; and a striking plate, fixedly connected to the outer surface of the rotating rod of the rotating mechanism.
[0011] As a further preferred embodiment of this technical solution, it also includes: a mounting plate, fixedly connected to the feeding hourglass; and a fixing bolt, threadedly connected to the threaded hole of the mounting plate.
[0012] This utility model provides a feeding structure for rice screening machinery used in rice production, which has the following beneficial effects:
[0013] (1) This utility model adds rice into the feeding hourglass, and the weight of the rice falls into the quantitative frame to store the rice in a quantitative manner. When the cylinder is turned on and the quantitative frame is pushed forward, the bottom of the quantitative frame separates from the support base plate, and the rice in the quantitative frame falls onto the rice sieve machine for sieving. This structural design can quantitatively feed rice, prevent excessive feeding of rice, and improve the screening quality of the rice sieve machine.
[0014] (2) Through the structural design of the filter screen and the rotating mechanism, when the rice slides onto the filter screen, the motor on the rotating mechanism is turned on, the rotating rod rotates below the filter screen, and the beating plate beats the bottom of the filter screen, so that the filter screen screens the rice, thereby filtering and screening the dust in the rice, preventing the rice from having too much dust when it enters the screening machine, which would affect the working environment.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figure 1 - Figure 4 As shown in this embodiment, a feeding structure based on a rice sieving machine for rice production includes: a feeding hourglass 1; a supporting base plate 12, fixedly connected inside the feeding hourglass 1; a metering frame 9, slidably connected to the supporting base plate 12; a cylinder 4, installed on the feeding hourglass 1, with the telescopic end of the cylinder 4 fixedly connected to one side of the metering frame 9; a connecting plate 3, fixedly connected to the cylinder 4; and a filter screen 8, installed inside the feeding hourglass 1. The metering frame 9 and the supporting base plate 12 are configured to cooperate with the feeding hourglass 1 to quantitatively feed the rice, wherein the metering frame 9 and the supporting base plate 12 are combined to form a metering cylinder, which quantitatively feeds the rice from the rice sieving machine.
[0022] By adding rice into the feeding hourglass 1, the weight of the rice falls into the metering frame 9, storing the rice in a fixed quantity. When the cylinder 4 is turned on, the metering frame 9 is pushed forward. When the bottom of the metering frame 9 separates from the support base plate 12, the rice in the metering frame 9 falls onto the rice sieve for sieving. This structural design can quantitatively feed rice, prevent excessive feeding, and improve the screening quality of the rice sieve.
[0023] like Figure 2 - Figure 4 As shown, it also includes: a scraper 15, installed inside the discharge sand hourglass 1.
[0024] Through the structural design of the scraper 15, when the metering frame 9 is pulled to the initial position, the scraper 15 can prevent rice from getting stuck in the sliding gap between the connecting plate 3 and the feeding hourglass 1.
[0025] like Figure 4 As shown, it also includes: a reinforcing rib 16, which is fixedly connected to the connecting plate 3, and one end of the reinforcing rib 16 is fixedly connected to one side of the quantitative frame 9.
[0026] The structural design of the reinforcing rib 16 can improve the strength between the connecting plate 3 and the quantitative frame 9, preventing the connecting plate 3 from deforming when rice is pressed on it.
[0027] like Figure 1 - Figure 3 As shown, it also includes: a storage box 2, which is slidably connected inside the discharge hourglass 1 and is located below the filter screen 8; and a baffle 7, which is fixedly connected inside the discharge hourglass 1.
[0028] As the rice slides along the baffle 7 onto the filter screen 8, the filter screen 8 filters out the dust in the rice, preventing excessive dust from entering the rice sieve machine and thus affecting the working environment.
[0029] like Figure 1 and Figure 2 As shown, it also includes: a mounting ear 11, which is fixedly connected to the feeding hourglass 1; and a fixing rod 10, which is slidably connected inside the mounting ear 11.
[0030] By using the structural design of the fixed insertion rod 10 and the mounting ear 11, the fixed insertion rod 10 is inserted into the mounting ear 11, and the storage box 2 is fixed in the feeding sand hourglass 1, preventing the storage box 2 from sliding out of the feeding sand hourglass 1 due to the vibration generated when the rice sieve machine is working.
[0031] like Figure 2 and Figure 3 As shown, it also includes: a rotating mechanism 13, which is installed on the feeding hourglass 1; and a striking plate 14, which is fixedly connected to the outer surface of the rotating rod of the rotating mechanism 13. The rotating mechanism 13 consists of a motor and a rotating rod, and the striking plate 14 is made of rubber.
[0032] By turning on the motor on the rotating mechanism 13, the rotating rod rotates below the filter screen 8, and the beating plate 14 beats the bottom of the filter screen 8, thereby improving the filtration effect of the filter screen 8.
[0033] like Figure 1 and Figure 2 As shown, it also includes: a mounting plate 5, which is fixedly connected to the feeding hourglass 1; and a fixing bolt 6, which is threadedly connected to the threaded hole of the mounting plate 5.
[0034] Through the structural design of fixing bolts 6 and mounting plate 5, the feeding sand hourglass 1 can be stably installed on the rice sieve machine.
[0035] This utility model provides a feeding structure based on rice screening machinery used in rice production, and its specific working principle is as follows:
[0036] When feeding rice, rice is first added into the feeding hourglass 1. The rice slides along the baffle 7 onto the filter screen 8, which filters the rice and stores the dust in the storage box 2. At the same time, the motor on the rotating mechanism 13 is turned on, and the beater 14 beats the bottom of the filter screen 8 to improve the screening efficiency. When the rice falls into the metering frame 9, the rice is metered. After metering, the cylinder 4 is turned on, and the metering frame 9 slides on the support base plate 12. When the bottom of the metering frame 9 separates from the support base plate 12, the rice in the metering frame 9 falls onto the rice sieving machine for screening. When the rice in the metering frame 9 is completely discharged, the cylinder 4 pulls the metering frame 9 back to its initial position. At the same time, the rice on the connecting plate 3 is scraped into the metering frame 9 by the scraper 15 and the inner wall of the feeding hourglass 1 for metering. The above operation is repeated to meter the rice.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
