Description

Technical Field

[0001] The utility model relates to the technical field of sand roller rice milling machines, in particular to a vertical sand roller rice milling machine. Background Art

[0002] After retrieving the patent document with the publication number of CN215353583U, materials enter the rice milling chamber, and the conical sand roller and the screen rotate in different directions to rub and hull the rice. At the same time, the rotation of the inner impeller sucks the chaff out of the screen and discharges it from the chaff outlet pipe, while the rice is sent out to the outside through the rice outlet pipe.

[0003] When the patent document processes the grain for hulling, since the chaff generates suction through the rotation of the impeller to suck the chaff out of the screen, in this process, due to the limited intake space at the upper end of the whole device and the possible accumulation of a certain amount of rice, the suction generated by the impeller may be small. And if there is more rice inside the screen, it will also affect the suction of the whole impeller. Subsequently, the chaff is likely to adhere to the inside of the screen, affecting the screening process of the chaff and the rice grains. At the same time, the accumulated chaff will jam the rice grains, causing the rice grains to rub against the conical sand roller, easily damaging the integrity of the rice grains and affecting the hulling quality of the rice. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a vertical sand roller rice milling machine to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A vertical sand roller rice milling machine includes a rice milling mechanism, a diversion mechanism for controlling the flow rate of rice is arranged on the rice milling mechanism, and a screening mechanism for quickly separating rice grains and chaff is also included;

[0007] The screening mechanism includes a screening barrel. An outlet pipe for blowing out the chaff is arranged on the upper side of the screening barrel, an outlet pipe for sending out the rice grains is arranged on the lower side of the screening barrel. Inside the screening barrel, a conical sieve plate and a sliding sleeve are arranged. The conical sieve plate is fixed at the upper end of the sliding sleeve. A piston seat is slidably connected inside the sliding sleeve. Two symmetrically arranged guide rods are fixed at the top of the piston seat. A rotating shaft is arranged at the central position of the sliding sleeve.

[0008] Preferably: a guide groove for facilitating the sliding of the upper end of the guide rod is opened inside the screening barrel, and a blowing pipe passing through the screening barrel is arranged on one side of the sliding sleeve.

[0009] Preferably: four T-shaped sliders are opened at the central position of the sliding sleeve, and T-shaped chutes matching the T-shaped sliders are opened on the outer side of the rotating shaft.

[0010] Preferably, the rice milling mechanism includes a rice milling frame. A rice inlet hopper is fixed to the upper end of the rice milling frame. A rice milling seat is fixed inside the rice milling frame. A rice milling roller is provided inside the rice milling seat. A bracket for supporting the upper end of the rice milling roller is provided.

[0011] Preferably, the lower end of the rice milling roller is fixedly connected to the upper end of a rotating shaft. A driving motor is fixedly arranged at the lower end of the rotating shaft. Three legs are fixed to the bottom of the screening barrel.

[0013] The beneficial effects compared with the prior art are as follows:

[0014] 1. Rice milling is carried out by the rotation of the rotating shaft. At the same time, the piston seat and the guiding rod are also driven to rotate. The piston seat moves up and down by the rotation of the guiding rod in the guiding groove of the screening barrel, so as to push the rice grains and chaff out to the conical sieve plate for screening, preventing congestion of the rice grains and chaff during the screening process and affecting the whole screening and rice milling speed.

[0015] 2. When the piston seat moves out of the sliding sleeve, the air blowing pipe supplies compressed air into the sliding sleeve to blow the chaff above the conical sieve plate and the rice grains below it, and then quickly discharges the rice grains and chaff from the position of the conical sieve plate, further avoiding the situation of chaff blocking the conical sieve plate.

[0030] The present utility model will be further described below with reference to the accompanying drawings:

[0031] As Figures 1-9 shown, a vertical sand roller rice mill includes a rice milling mechanism 1, a diversion mechanism 2 for controlling the flow rate of rice is provided on the rice milling mechanism 1, and a screening mechanism 3 for quickly separating rice grains and chaff is further included;

[0032] In this embodiment: The screening mechanism 3 includes a screening barrel 31, an outlet pipe 32 for blowing out chaff is provided on the upper side of the screening barrel 31, an outlet pipe 33 for sending out rice grains is provided on the lower side of the screening barrel 31, a conical sieve plate 35 and a sliding sleeve 36 are arranged inside the screening barrel 31, the conical sieve plate 35 is fixed at the upper end of the sliding sleeve 36, a piston seat 37 is slidably connected inside the sliding sleeve 36, two symmetrically arranged guide rods 38 are fixed at the top of the piston seat 37, a rotating shaft 39 is arranged at the central position of the sliding sleeve 36, a guide groove for facilitating the sliding of the upper end of the guide rod 38 is opened inside the screening barrel 31, a blowing pipe 34 passing through the screening barrel 31 is provided on one side of the sliding sleeve 36, four T-shaped sliders are opened at the central position of the sliding sleeve 36, and a T-shaped chute matching with the T-shaped sliders is opened on the outer side of the rotating shaft 39. The rotation of the rotating shaft 39 is used to drive the piston seat 37 to rotate inside the sliding sleeve 36, and at the same time, the piston seat 37 drives the guide rod 38 to move in the guide groove of the screening barrel 31. With the undulation of the guide groove, the piston seat 37 is driven to move up and down along the T-shaped chute of the rotating shaft 39, so as to push the chaff and rice grains accumulated inside the sliding sleeve 36 upward. Immediately, the pushed rice grains and chaff will fall back onto the conical sieve plate 35, and then the conical sieve plate 35 is used to screen the rice grains and chaff. In addition, when the piston seat 37 leaves the sliding sleeve 36, air is blown into the sliding sleeve 36 through the blowing pipe 34, so as to send the chaff on the upper side of the conical sieve plate 35 out through the outlet pipe 32 along with the blown-in gas, and the screened rice grains are sent out through the outlet pipe 33.

[0033] In this embodiment: The rice milling mechanism 1 includes a rice milling frame 12. At the upper end of the rice milling frame 12, a rice inlet hopper 11 is fixed. Inside the rice milling frame 12, a rice milling seat 13 is fixed. Inside the rice milling seat 13, a rice milling roller 14 is provided. At the upper end of the rice milling roller 14, there is a bracket for supporting it. The lower end of the rice milling roller 14 is fixedly connected to the upper end of a rotating shaft 39. At the lower end of the rotating shaft 39, a driving motor 4 is fixedly arranged. Three legs 5 are fixed at the bottom of the screening barrel 31. The driving motor 4 drives the rice milling roller 14 to rotate inside the rice milling seat 13 through the rotating shaft 39. At the same time, the rice is introduced between the rice milling seat 13 and the rice milling roller 14 through the rice inlet hopper 11. Then, the rice grains are pressed against the rice milling seat 13 by the rotating rice milling roller 14, so as to separate the chaff and the rice grains of the rice.

[0034] In this embodiment: The diversion mechanism 2 includes a flap 21. The flap 21 is rotatably connected to the lower end of the rice inlet hopper 11. At the end of the flap 21 extending out of the rice inlet hopper 11, a ratchet wheel 22 is fixed. Below the ratchet wheel 22, there is a sliding seat 23. The sliding seat 23 is slidably connected inside a limit frame 24, and a spring for resetting it is fixed at the end of the sliding seat 23. By pulling out the sliding seat 23 to release the locking of the ratchet wheel 22, the flap 21 can be rotated to adjust the amount of rice entering the rice milling frame 12. After the adjustment is completed, the spring pushes the sliding seat 23 to cooperate with the ratchet wheel 22 again, and then the flipping angle of the flap 21 is locked.

[0035] Working principle: When in use, first introduce the rice to be husked into the rice inlet hopper 11. By pulling out the sliding seat 23 to release the locking of the ratchet wheel 22, the flap 21 can be rotated to adjust the amount of rice entering the rice milling frame 12. After the adjustment is completed, the spring pushes the sliding seat 23 to cooperate with the ratchet wheel 22 again, and then the flipping angle of the flap 21 is locked. After that, the rice will enter the gap between the rice milling seat 13 and the rice milling roller 14 inside the rice milling frame 12. The driving motor 4 drives the rice milling roller 14 to rotate inside the rice milling seat 13 through the rotating shaft 39. The rice is pressed against the rice milling seat 13 by the rotation of the rice milling roller 14. When the chaff and the rice grains of the rice are separated, both the chaff and the rice grains will fall out from the gap between the rice milling seat 13 and the rice milling roller 14;

[0036] The discharged chaff and rice grains will fall onto the piston seat 37 inside the sliding sleeve 36. At the same time, the T-shaped slider of the piston seat 37 cooperates with the T-shaped chute of the rotating shaft 39. Thus, when the rotating shaft 39 rotates, the piston seat 37 will also rotate accordingly. When the piston seat 37 rotates, it will drive the guide rod 38 to move along the guide groove of the screening barrel 31. With the undulation of the guide groove, the guide rod 38 will drive the piston seat 37 to move axially up and down along the rotating shaft 39. Through the up and down movement of the piston seat 37, the rice grains and chaff are pushed upward. The discharged chaff and rice grains will fall onto the conical sieve plate 35, and the rice grains and chaff are separated by the conical sieve plate 35. Then, the rice grains will fall below the conical sieve plate 35, while the chaff will fall above the conical sieve plate 35.

[0037] In addition, when the piston seat 37 leaves the sliding sleeve 36, the compressed air in the air blowing pipe 34 will enter the sliding sleeve 36. Through the blowing force of the compressed air, the chaff on the conical sieve plate 35 and the rice grains on its lower side are blown out from the chaff outlet pipe 32 and the rice outlet pipe 33 respectively. When the piston seat 37 falls into the sliding sleeve 36, the compressed air is isolated, and then the entire rice milling process is completed.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
