Description

Technical Field

[0001] This utility model relates to the field of rice milling machine technology, specifically to a rice milling machine bran dispensing device. Background Technology

[0002] A rice milling machine mainly consists of a fixed wrench, a tightening nut wrench, a brush, a hopper, a grinding wheel, and a wire brush. It utilizes the mechanical force generated by machinery to remove the husk from brown rice; the machinery used is called a rice milling machine. Small rice milling machines mainly come in three types: separate rice milling machines, combined hulling and milling machines, and air-jet rice milling machines. To reduce the broken rice rate and improve rice quality, a multi-machine, light-milling process must be adopted. During operation, rice milling machines produce a large amount of rice bran, which is generally collected and used as livestock feed. However, the bran-dispensing devices in currently used rice milling machines are relatively simple in structure.

[0003] A search revealed a rice milling machine bran dispensing device (CN216856797U), comprising a base, a rice milling machine body mounted on the top outer wall of the base, a bran outlet pipe on one side outer wall of the top of the rice milling machine body, a feed pipe sleeved on one side outer wall of the bran outlet pipe, a box fixedly connected to one side outer wall of the rice milling machine body, the box being connected to the feed pipe, a rectangular hole on one side outer wall of the box, a latch plate slidably connected to the inner wall of the rectangular hole, the latch plate being L-shaped, pulleys threadedly connected to the four corners of the bottom outer wall of the latch plate, brackets fixedly connected to the two sides outer walls of the top of the latch plate, hydraulic rods mounted on one side inner wall of each bracket, and clamps screwed to one end of the piston rod of each hydraulic rod, the clamps being arc-shaped.

[0004] The implementation of this technical solution has at least the following drawbacks: Although this utility model can compress and limit the opening of the collection bag and the feed pipe, it is inconvenient to seal the lower end of the feed pipe after the collection bag is full. If a valve is installed at the lower end of the feed pipe, it will affect the compression and limitation of the collection bag, which urgently needs to be improved. Therefore, we propose a bran mixing device for a rice milling machine. Utility Model Content

[0005] The purpose of this utility model is to provide a bran feeding device for a rice milling machine, which solves the problem mentioned in the background art that it is inconvenient to seal the lower end of the feed pipe after the collection bag is full, and that setting a valve at the lower end of the feed pipe would affect the compression and limitation of the collection bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice milling machine's bran-dispensing device, comprising a rice milling machine body, a discharge pipe connected to one side of the rice milling machine body, a feed hopper connected to the upper middle part of the rice milling machine body, a hydraulic cylinder fixedly installed on one side of the discharge pipe, a piston rod installed at the output end of the hydraulic cylinder, a piston cylinder provided below the piston rod, an annular air bladder bonded to the lower outer wall of the discharge pipe, multiple protrusions bonded to the outer side of the annular air bladder, a fixing rod fixedly installed in the middle of the piston rod, and a circular block fixedly installed at the lower end of the fixing rod.

[0007] By adopting the above technical solution, the hydraulic cylinder can drive the piston rod to move downwards, causing the piston rod to separate the circular block on the fixed rod from the discharge pipe. At the same time, the piston rod will compress the air in the piston cylinder, expelling the air into the annular air bladder through the hose. The annular air bladder inflates and causes the protrusions on its surface to press against the edge of the collection bag, thus opening and limiting the opening of the collection bag, making it easier to fill with sawdust. Alternatively, the piston rod can draw air from the annular air bladder into the piston cylinder through the hose, making it easier to remove the collection bag. Meanwhile, the piston rod will drive the fixed rod to move upwards, causing the fixed rod to move the circular block and rubber ring to seal the lower edge of the discharge pipe. This solves the problem of rice bran spilling because it is inconvenient to seal the lower edge of the inlet pipe after the collection bag is full.

[0008] Optionally, the outlet end of the piston cylinder is connected to a flexible hose, and the other end of the flexible hose is connected to the inlet end of the annular airbag.

[0009] By adopting the above technical solution and using the hose, the gas inside the piston cylinder can be guided.

[0010] Optionally, the size of the piston rod is adapted to the inner cavity size of the piston cylinder, and the piston rod is movably connected to the piston cylinder.

[0011] By adopting the above technical solution, the annular airbag can be inflated or deflated through the cooperation of the piston rod and the piston cylinder.

[0012] Optionally, the bumps are configured as a plurality of bumps, and the plurality of bumps are arranged in a ring.

[0013] By adopting the above technical solution and setting the protrusions, the opening and limiting effect of the annular airbag on the collection bag can be increased.

[0014] Optionally, the lower end of the fixing rod extends through the inner cavity of the discharge pipe.

[0015] By adopting the above technical solution and setting a fixed rod, the circular block can be moved up and down.

[0016] Optionally, a rubber ring is bonded to the outer side of the circular block, and the outer side of the rubber ring is in contact with the inner wall of the discharge pipe.

[0017] By adopting the above technical solution and setting the rubber ring, the sealing effect of the circular block on the lower end of the discharge pipe can be guaranteed.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the design of a rice milling machine body, discharge pipe, hydraulic cylinder, piston cylinder, piston rod, annular air bladder, circular block, and rubber ring, allows the hydraulic cylinder to drive the piston rod downward, causing the circular block on the fixed rod to separate from the discharge pipe opening. Simultaneously, the piston rod compresses the air inside the piston cylinder, expelling it through a hose into the annular air bladder. The annular air bladder inflates, causing its surface protrusions to press against the edge of the collection bag, thus opening and limiting the bag opening for easy filling with sawdust. Alternatively, the piston rod can draw air from the annular air bladder into the piston cylinder through the hose, facilitating the removal of the collection bag. At the same time, the piston rod drives the fixed rod upward, causing it to move the circular block and rubber ring to seal the lower edge of the discharge pipe. This solves the problem of rice bran spilling due to the inconvenience of sealing the lower edge of the inlet pipe after the collection bag is full. Attached Figure Description

[0025] Please see Figure 1-3This utility model provides a technical solution: a rice milling machine bran dispensing device, including a rice milling machine body 1, a discharge pipe 11 connected to one side of the rice milling machine body 1, a feed hopper 12 connected to the upper middle part of the rice milling machine body 1, a hydraulic cylinder 2 fixedly installed on one side of the discharge pipe 11, a piston rod 22 installed at the output end of the hydraulic cylinder 2, a piston cylinder 21 arranged below the piston rod 22, an annular air bladder 24 bonded to the lower outer wall of the discharge pipe 11, multiple protrusions 25 bonded to the outer side of the annular air bladder 24, and a fixing rod 3 fixedly installed in the middle of the piston rod 22. A circular block 4 is fixedly installed at the lower end of the 3. Multiple protrusions 25 are arranged in a ring. The protrusions 25 can increase the opening and limiting effect of the annular airbag 24 on the collection bag. The lower end of the fixing rod 3 passes through the inner cavity of the discharge pipe 11. The fixing rod 3 can drive the circular block 4 to move up and down. A rubber ring 5 is bonded to the outside of the circular block 4. The outside of the rubber ring 5 is in contact with the inner wall of the discharge pipe 11. The rubber ring 5 can ensure the sealing effect of the circular block 4 on the lower end of the discharge pipe 11.

[0026] The outlet end of the piston cylinder 21 is connected to a hose 23, and the other end of the hose 23 is connected to the inlet end of the annular airbag 24. Through the hose 23, the gas inside the piston cylinder 21 can be guided.

[0027] The piston rod 22 is adapted to the inner cavity size of the piston cylinder 21, and the piston rod 22 is movably connected to the piston cylinder 21. Through the cooperation between the piston rod 22 and the piston cylinder 21, the annular airbag 24 can be inflated or deflated.

[0028] When the rice milling machine's bran mixing device is used, the paddy rice is crushed inside the milling machine, and the bran is discharged through the discharge pipe 11. Simultaneously, a collection bag is placed over the outside of the discharge pipe 11. Then, the hydraulic cylinder 2 is controlled to move downwards, causing the piston rod 22 to move downwards. The piston rod 22 causes the circular block 4 on the fixed rod 3 to separate from the outlet of the discharge pipe 11. At the same time, the piston rod 22 compresses the air inside the piston cylinder 21, expelling it through the hose 23 into the annular air bladder 24. The annular air bladder 24 inflates, causing the protrusions 25 on its surface to press against the edge of the collection bag. The collection bag opening is then widened to facilitate the filling of sawdust. Once the sawdust is mixed, the hydraulic cylinder 2 is moved upward, which in turn moves the piston rod 22 upward. This causes the piston rod 22 to draw air from the annular airbag 24 into the piston cylinder 21 through the hose 23, making it easier to remove the collection bag. At the same time, the piston rod 22 moves the fixing rod 3 upward, causing the fixing rod 3 to move the circular block 4 and the rubber ring 5 to seal the lower edge of the discharge pipe 11. This solves the problem of rice bran spilling because it is inconvenient to seal the lower edge of the inlet pipe after the collection bag is full.
