Description
Technical Field
The utility model relates to the field of machinary, especially, relate to a rice destoner.
Background
The rice stone remover is a device for separating rice from stones, and is based on the principle that a vibrating fish-scale screen is arranged and is ventilated from bottom to top at the bottom of the screen, so that lighter rice is in a suspension fluidized state, and heavier stones move upwards along the screen under the vibration of a specific frequency, so that the rice flows downwards and substantially moves upwards, and the effect of separating the rice from the stones is achieved.
However, this method depends on the frequency of the vibration and the feeding speed, if the feeding speed is too high, the materials are too much, so that part of the rice and the stones are at the bottom and move upwards under the vibration, and part of the rice and the stones flow out together, and if the feeding speed is too low, the separation efficiency is affected.
In addition, current stoner divides into two kinds of positive pressure formula and negative pressure formula, and the positive pressure formula is blown upwards from the bottom promptly for present the malleation state in the cavity, this kind of mode makes the air flow out from the gas outlet easily except, still can flow out from the discharge gate, and still can have rice husk, rice stalk, dust etc. in the air, not only leads to operational environment dust to overflow all around easily, leads to mixing more rice husk and rice stalk in the rice of ejection of compact moreover.
The negative pressure type adopts a negative pressure pump or a negative pressure fan to suck air from the upper part, so that the cavity is in a negative pressure state. However, the negative pressure pump or the negative pressure fan is driven by the fan blades, and when the air is sucked, light substances such as rice shells, rice stalks, dust and the like contained in the rice easily impact the fan blades, so that the service life of the fan blades is short.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a rice destoner.
The purpose of the utility model is realized through the following technical scheme:
a rice stone removing machine comprises a shell, wherein one end of the top of the shell is provided with a feeding pipe, the other end of the top of the shell can be provided with an air outlet, the other end of the bottom of the shell is provided with a discharge hole, a scale sieve plate is arranged in the shell and connected with a vibrator, one end of the scale sieve plate is provided with a stone outlet, and the other end of the scale sieve plate is a discharge hole; the feeding pipe penetrates through a rotating shaft, the rotating shaft is connected with a rotating device, a plurality of quantitative fan blades are uniformly fixed on the rotating shaft along the circumferential direction, and adjacent quantitative fan blades and the inner wall of the feeding pipe are enclosed to form a quantitative hopper; an air amplifier is installed at the air outlet and connected with a dust collecting cloth bag through a communicating pipe.
In a further improvement, a screen is arranged below the fish scale sieve plate.
In a further improvement, a convex ring is protruded on the communicating pipe.
In a further improvement, the rotating device is a variable frequency speed reducing motor.
In a further improvement, the bottom of the shell is provided with a support leg.
In a further improvement, a stone receiving hopper is fixed on the supporting leg.
The utility model discloses following beneficial effect has.
1. The utility model discloses can be so that the rice can be at the uniform velocity feeding in the destoner to guaranteed that rice input speed can be in the partial rice that preset transport state avoided the feeding to lead to at the excessive speed and shone out, or the efficiency that the feeding leads to too slowly reduces.
2. Negative pressure is formed through the air amplifier, so that the problem that the service life of the existing negative pressure device with fan blades is short due to the fact that the existing negative pressure device with fan blades is easy to be caused by a particle device is solved.
Drawings
The present invention is further explained by using the attached drawings, but the content in the attached drawings does not constitute any limitation to the present invention.
Fig. 1 is a schematic view of the overall structure of a rice stone remover.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Example 1
The rice stone removing machine shown in fig. 1 comprises a shell 1, a feeding pipe 2, a discharging port 3, a fish scale sieve plate 4, a vibrator 5, a stone outlet 6, a rotating shaft 7, a rotating device 8, quantitative fan blades 9, a quantitative hopper 10, an air outlet 11, an air amplifier 12, a communicating pipe 13, a dust collecting cloth bag 14, a screen 15, supporting legs 16, a convex ring 17 and a stone receiving hopper 18.
Wherein the feeding pipe 2 is arranged at one end of the top of the shell 1, and the air outlet 11 is arranged at the other end of the top of the shell 1. An air amplifier 12 is installed at the air outlet 11. The air amplifier 12 is connected to a dust collecting bag 14 through a communication pipe 13.
A fish scale sieve plate 4 is arranged in the shell 1, and the fish scale sieve plate 4 is connected with a vibrator 5. The fish scale sieve plate 4 is obliquely arranged, a stone outlet 6 is arranged at one end of the upper part of the fish scale sieve plate 4, and a discharge hole 3 is arranged at the end part of one end of the lower part of the fish scale sieve plate 4.
In order to keep stable feeding, the feeding pipe 2 penetrates through a rotating shaft 7, the rotating shaft 7 is connected with a variable-frequency speed reduction motor, a plurality of quantitative fan blades 9 are uniformly fixed on the rotating shaft 7 along the circumferential direction, and the inner walls of the adjacent quantitative fan blades 9 and the feeding pipe 2 are enclosed to form a quantitative hopper 10.
Thus, the utility model discloses during the use, start vibrator 5, air amplifier 12 and frequency conversion gear motor, then pour into the rice of waiting to go the stone in to inlet pipe 2, the rice gets into in the constant volume fill 10 to on fish scale sieve 4 is fallen along with frequency conversion gear motor's rotation, because the frequency conversion gear motor rotational speed is fixed, consequently rice unloading speed also is fixed, thereby keeps the at the uniform velocity feeding of rice. The rice falls on the fish scale sieve plate 4 and is blown by airflow to be suspended, and the stones with high density are contacted with the fish scale sieve plate 4 and gradually move upwards along the fish scale sieve plate 4 to the stone outlet 6 to enter the stone receiving hopper 18 under the condition of vibration.
