Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice transportation technology, specifically to a side feeding device for a rice scraper. Background Technology
[0002] The rice scraper conveyor is an improved version of similar foreign products. It is mainly used for transporting materials that are prone to breakage. It can feed at multiple points and discharge at multiple locations. It has low noise, low failure rate, and has the advantages of beautiful appearance, good sealing, stable operation, simple and convenient maintenance, and low energy consumption.
[0003] Existing rice scraper machines on the market generally use a top-mounted feeding device to directly feed processed rice into the scraper machine for conveying. However, in actual use, the top-mounted feeding device design can easily cause rice to fall into the chain during feeding due to excessive height or misalignment between the pipe and the scraper, resulting in the rice being crushed or even damaging the device. To address this, we propose a side-feeding device for rice scraper machines. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a side feeding device for a rice scraper machine. This solves the problem that in actual use, the top-mounted feeding device is prone to rice falling into the chain during feeding due to excessive height or misalignment between the pipe and the scraper, causing the rice to be crushed or even damaging the device.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A lateral feeding device for a rice scraper machine includes a scraper machine housing. A first through hole is provided on one side of the scraper machine housing. A first feeding pipe is provided inside the first through hole. A second feeding pipe is provided on the bottom surface of the first feeding pipe. The first feeding pipe and the second feeding pipe are connected. A connecting frame is provided on the outer wall of the second feeding pipe. Limiting claws are fixedly installed on both sides of the connecting frame. The limiting claws have an L-shaped structure.
[0007] Preferably, a snap-fit sleeve is fixedly installed on the outer wall of the first feeding pipe, and the first feeding pipe is snapped together with the first through hole through the snap-fit sleeve. Two snap-fit holes are opened on both sides of the second feeding pipe, and two snap-fit blocks are fixedly installed on both sides of the inner side of the connecting frame. The connecting frame is snapped together with the second feeding pipe through the snap-fit holes and the snap-fit blocks.
[0008] Preferably, a fixing plate is fixedly installed inside the connecting frame. The top surface of the fixing plate has a second through hole and several arc-shaped holes. A sliding rod is sleeved inside the second through hole. A baffle is fixedly installed at the top of the sliding rod, and a contact block is fixedly installed at the bottom of the sliding rod. The contact block is a truncated pyramid structure with a trapezoidal cross-section.
[0009] Preferably, a spring is provided on the outer wall surface of the sliding rod, and the spring is limited by the fixing plate and the baffle.
[0010] Preferably, the scraper conveyor housing has connecting grooves on both sides of its interior, and two connecting blocks are fixedly installed on one side of the scraper conveyor housing. Screw holes are provided on one side of the connecting groove and one side of the connecting block.
[0011] In summary, the present invention has the following main advantages:
[0012] 1. By setting up a first feeding pipe, and through the design of the first feeding pipe and the second feeding pipe, the distance between the feeding pipe and the scraper is smaller than that of the design of the feeding pipe being set above. This avoids rice grains falling above the scraper and then bouncing into the track and being crushed, causing unnecessary losses. The design of the limiting claw can calibrate and limit the position of the pipe and the scraper. When the scraper and the pipe are not aligned, the limiting claw will block the scraper, causing the device to malfunction until the problem is solved.
[0013] 2. By setting a sliding rod, and through the design of the sliding rod, baffle and contact block, it can serve as an automatic feeding device. When the scraper passes under the connecting frame, it will contact the inclined surface of the contact block, generating an upward force that forces the baffle to move up, exposing the arc-shaped hole so that the material falls onto the scraper, thereby achieving automatic and precise feeding. Through the spring design, its elasticity can help the scraper return to the state of blocking the arc-shaped hole when it leaves the position under the connecting frame, in conjunction with the elasticity of the baffle itself, facilitating the next use of the device.

[0019] 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.
[0020] refer to Figures 1-4 A side-feeding device for a rice scraper machine includes a scraper machine housing 1. A first through hole 2 is provided on one side of the scraper machine housing 1. A first feeding pipe 3 is provided inside the first through hole 2. A second feeding pipe 4 is provided on the bottom surface of the first feeding pipe 3. The first feeding pipe 3 and the second feeding pipe 4 are connected. By designing the first feeding pipe 3 and the second feeding pipe 4, the distance between the feeding pipe and the scraper is smaller than that of the scraper machine, which avoids rice grains falling above the scraper machine and then being crushed in the conveyor belt, causing unnecessary losses. A connecting frame 5 is provided on the outer wall of the second feeding pipe 4. Limiting claws 6 are fixedly installed on both sides of the connecting frame 5. The limiting claws 6 have an L-shaped structure. By designing the limiting claws 6, the position of the pipe and the scraper machine can be calibrated and limited. When the scraper machine and the pipe are not aligned, the limiting claws 6 will block the scraper machine, causing the device to malfunction until the problem is solved.
[0021] A snap-fit sleeve 7 is fixedly installed on the outer wall of the first feeding pipe 3. The snap-fit sleeve 7 is designed to limit the position of the first feeding pipe 3 while ensuring the integrity of the outer wall of the scraper casing 1, so as to avoid large displacement under external force. The first feeding pipe 3 is snapped together with the first through hole 2 through the snap-fit sleeve 7. Two snap-fit holes 8 are opened on both sides of the second feeding pipe 4. Two snap-fit blocks 9 are fixedly installed on both sides of the inside of the connecting frame 5. The connecting frame 5 is snapped together with the second feeding pipe 4 through the snap-fit holes 8 and the snap-fit blocks 9. The design of the snap-fit holes 8 and the snap-fit blocks 9 allows for flexible disassembly and installation of the connecting frame 5 and the structure installed with the connecting frame 5 according to the actual situation, increasing the flexibility of the device.
[0022] A fixing plate 10 is fixedly installed inside the connecting frame 5. The top surface of the fixing plate 10 has a second through hole 11 and several arc-shaped holes 12. A sliding rod 13 is fitted inside the second through hole 11. A baffle 14 is fixedly installed at the top of the sliding rod 13 and a contact block 15 is fixedly installed at the bottom of the sliding rod 13. The contact block 15 is a trapezoidal truncated pyramid structure. Through the design of the sliding rod 13, the baffle 14 and the contact block 15, it can be used as an automatic feeding device. When the scraper passes under the connecting frame 5, it will contact the inclined surface of the contact block 15, generating an upward component force, forcing the baffle 14 to move upward, exposing the arc-shaped holes 12 so that the material falls onto the scraper, thereby achieving automatic and precise feeding.
[0023] A spring 16 is provided on the outer wall of the sliding rod 13. The spring 16 is limited by the fixing plate 10 and the baffle 14. Through the design of the spring 16, when the scraper plate leaves the position below the connecting frame 5, it can be assisted by the elastic force of the baffle 14 itself to return to the state of blocking the arc hole 12, so as to facilitate the next use of the device.
[0024] The scraper conveyor housing 1 has connecting grooves 17 on both sides inside. Two connecting blocks 18 are fixedly installed on one side of the scraper conveyor housing 1. Threaded holes 19 are provided on one side of the connecting grooves 17 and one side of the connecting blocks 18. Through the design of the connecting grooves 17, connecting blocks 18 and threaded holes 19, bolts can be threaded into the threaded holes 19 during actual use, allowing the two scraper conveyor housings 1 to be spliced together. This facilitates the application of the device in long-distance transportation and gives the device a wider range of applications.
[0025] 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.
