Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural product processing technology, specifically a broken rice filtering device. Background Technology
[0002] Rice is an essential food for humans. Most of the rice consumed in modern cities or rural areas is processed. The rice processing process inevitably requires filtering and sieving the rice to separate rice grains of different sizes to meet processing requirements.
[0003] Currently, most rice screening and processing is done using a circular screen machine. The circular screen machine has multiple layers of screens and multiple rice outlets. Inside the circular screen machine, a vibrator drives the multiple layers of screens to vibrate, causing the rice to flow out from the multiple rice outlets and into different containers, thus completing the screening of the rice, separating the broken rice and improving the quality of rice processing.
[0004] Because a large amount of rice cannot be poured into a circular sieve at once during the filtration process, the feeding method for small circular sieves is to manually use a hopper to load a fixed amount of rice into the sieve. This results in discontinuous feeding of the sieve and low efficiency in filtering and screening broken rice.
[0005] Therefore, a broken rice filtering device is proposed. Utility Model Content
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The device includes a base, a mounting frame, and a filter screen. The filter screen has multiple layers, and all layers of the filter screen are movably mounted on the mounting frame. The mounting frame has multiple discharge ports, each corresponding to one layer of the filter screen. The mounting frame is mounted on the base by springs and is also equipped with a feeding device to automatically feed materials into the mounting frame.
[0008] A rice container can be placed below the discharge port. The mounting base is equipped with a vibration motor, which causes the machine casing to vibrate and the mounting frame to resonate and shake. The vibration, in conjunction with the filter screen, filters and sieves the rice, separating broken rice from larger grains.
[0009] Preferably, the feeding device includes a feeding frame, a base plate, a sliding rod, and a baffle gate. The feeding frame is fixedly installed on the sliding rod, and a rice outlet is provided on the side of the feeding frame. The baffle gate is located on the rice outlet.
[0010] Preferably, the mounting frame has multiple sliding grooves, and multiple filter screens are slidably mounted on the sliding grooves. The side walls of the multiple filter screens are provided with closed plates, and each closed plate has a through hole. The side walls of the mounting frame are also provided with limiting holes, and the through holes correspond to the limiting holes.
[0011] Preferably, a screw is rotatably mounted on the side wall of the loading frame, and the bottom of the screw is rotatably connected to the top wall of the baffle gate.
[0012] Preferably, a sleeve is fixedly installed on the top wall of the protective base plate, the sleeve has threads inside, and a lifting rod is threadedly connected to the sleeve.
[0013] Preferably, the bottom of the base plate is fixedly equipped with multiple casters, and each caster is equipped with a locking device.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. The vibrating motor inside the base drives the filter screen to vibrate, separating broken rice from larger rice grains. A feeding device is set up, and a sufficient amount of rice to be screened and filtered is manually loaded into the feeding frame on the feeding device. Opening the baffle on the feeding frame allows the rice in the feeding frame to continuously and quantitatively flow into the installation frame for screening and filtration. There is no need to manually pour rice in quantitatively, and the efficiency of broken rice screening and filtration is high.
[0016] 2. The feeding device is made movable and can be moved next to the equipment to be screened and filtered according to processing needs. Since the feeding device is movable, the height of the equipment to be fed is not uniform. Adjust the height of the loading frame by rotating the lifting rod according to the height of the equipment to be fed, so as to adapt to the height of the feeding equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 2 This utility model provides a broken rice filtering device, the technical solution of which is as follows:
[0022] Example 1
[0023] A broken rice filtering device includes a base 1, a mounting frame 2, and a filter screen 3. The filter screen 3 has multiple layers, and all layers of the filter screen 3 are movably mounted on the mounting frame 2. The mounting frame 2 is mounted on the base 1 by springs. A feeding device is also provided to automatically feed the rice into the mounting frame 2.
[0024] The rice with a sieve is manually loaded into the feeding device beforehand, and then the feeding device is moved to the side of the base 1, and the feeding device continuously feeds rice into the installation frame 2.
[0025] The feeding device includes a loading frame 6 for storing rice. The bottom of the loading frame 6 is inclined, and a rice outlet is provided on the side of the loading frame 6. It also includes a base plate 10, a sliding rod 5, and a baffle 8. The loading frame 6 is fixedly installed on the sliding rod 5. There are multiple sliding rods 5, and all of them are fixedly installed on the base plate 10. The loading frame 6 is fixedly installed on the top wall of the multiple sliding rods 5. The baffle 8 is provided on the rice outlet, and a slot is provided on the outer wall of the rice outlet. The baffle 8 is inserted into the slot.
[0026] The side wall of the loading frame 6 is provided with an installation block, and a screw 9 is rotatably installed on the installation block. The installation block has a thread that engages with the screw 9. When the screw 9 is rotated, it can move vertically. The bottom of the screw 9 is rotatably connected to the top wall of the baffle gate 8. By rotating the screw 9, the vertical position of the baffle gate 8 can be adjusted, thereby adjusting the relative area between the baffle gate 8 and the rice outlet, and thus adjusting the flow rate of the rice outlet.
[0027] A sleeve 12 is fixedly installed on the top wall of the base plate 10. The sleeve 12 has a thread, and a lifting rod 11 is threadedly connected to the sleeve 12. The lifting rod 11 also has a thread and cooperates with the sleeve 12. The sliding rod 5 has two parts, which can slide relative to each other. The material loading frame 6 can be moved vertically by rotating the lifting rod 11. Multiple casters are fixedly installed at the bottom of the base plate 10. Each caster is equipped with a locking device, making the feeding device movable. It can be moved to the side of the equipment to be screened and filtered according to processing needs.
[0028] Since the feeding device is designed to be movable, the height of the equipment objects it feeds varies. The height of the loading frame 6 is adjusted by rotating the lifting rod 11 according to the height of the equipment object to adapt to the height of the feeding device.
[0029] Example 2
[0030] This embodiment is a further improvement based on Embodiment 1. The mounting frame 2 is provided with multiple sliding grooves, and multiple filter screens 3 are slidably installed on the sliding grooves. The side walls of the multiple filter screens 3 are provided with sealing plates 4, and each sealing plate 4 is provided with a through hole. The side walls of the mounting frame 2 are also provided with limiting holes, and the through holes correspond to the limiting holes.
[0031] Insert rods can be movably inserted into the through holes and limiting holes. The body of the sealing plate 4 is semi-circular, and the sliding groove is also semi-circular. The sealing plate 4 seals the sliding groove. Inserting the insert rod into the through holes and limiting holes can limit the movement of multiple filter plates and prevent the filter plates from sliding out.
[0032] During use, the mesh size of filter screen 3 needs to be changed. When the filter screen needs to be replaced, simply remove the insert rod 9 to replace it.
[0033] 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.
