[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-6A rice processing suction-type specific gravity stone removing machine includes a rice stone removing box 1, a waste outlet 6 and a rice outlet 7 are respectively opened on both sides of the rice stone removing box 1, an air blowing component 14 and a vibration stone removing component 15 are arranged inside the rice stone removing box 1; the vibration stone removing component 15 includes a mesh plate 151, a bracket 155 is symmetrically fixedly installed on the bottom of the mesh plate 151, a mounting plate seat 156 is fixedly installed on the inside of the bracket 155, and a center column 157 is fixedly installed on the side of the mounting plate seat 156, and the center column 157 slides out To the outside of the rice stone removing box 1, a mounting plate 159 is fixedly installed on the outer end of the central column 157, and a roller 1510 is rotatably installed on the side of the mounting plate 159. A driving motor 1511 is provided on the side of the roller 1510, and a cam 1512 is fixedly installed on the output end of the driving motor 1511. A second spring 1513 is fixedly installed on the inner end surface of the mounting plate 159, and an abutment ring 1514 is fixedly installed on the inner end of the second spring 1513, and the abutment ring 1514 abuts against the side wall of the rice stone removing box 1.

[0033] In this embodiment, the blowing assembly 14 includes a pressure-equalizing air chamber 141, and a plurality of blowing pipes 142 are evenly installed on the upper side of the pressure-equalizing air chamber 141. A connecting pipe 144 is installed on the side of the pressure-equalizing air chamber 141. The connecting pipe 144 passes through to the outside of the rice stone removing box 1 and the outside of the connecting pipe 144 is connected to an air pump 145. A dust filter cover 143 is fixedly installed on the upper end of the blowing pipe 142.

[0034] Through the above structure, the dust filter cover 143 enables the upper end of the air blowing pipe 142 to have a dust filtering function, thereby preventing dust from entering the air blowing pipe 142 through the upper end of the air blowing pipe 142.

[0035] In this embodiment, rubber frame pads 152 are installed on both sides of the mesh plate 151, and several first springs 153 are fixedly installed on the side of the mesh plate 151. A pad 154 is fixedly installed on the end of the first spring 153. The pad 154 and the first spring 153 are both located on the inner side of the rubber frame pad 152, and the pad 154 is in contact with the inner wall of the rubber frame pad 152.

[0036] With the above structure, the rubber frame pads 152 on both sides of the mesh plate 151 are in contact with the inner wall of the rice stone removing box 1 due to the rebound force of the first spring 153, thereby preventing the rice from slipping through the gaps on the sides during the stone removing process, resulting in incomplete rice stone removing. In addition, the first spring 153 has good deformation ability, so that when the mesh plate 151 vibrates, the rubber frame pads 152 can still maintain an abutment state with the inner wall of the rice stone removing box 1 under the elastic force of the first spring 153.

[0037] In this embodiment, side columns 158 are symmetrically installed on both sides of the central column 157, and the side columns 158 slide through to the outside of the rice stone removing box 1.

[0038] Through the above structure and the arrangement of the side columns 158 , the stability of the mesh plate 151 is ensured when it slides and vibrates in the rice stone removing box 1 following the central column 157 .

[0039] In this embodiment, a reinforcing casing is provided at the sliding insertion point between the central column 157 and the rice stone removing box 1 .

[0040] The above structure improves the connection strength of the sliding joint between the central column 157 and the rice stone removing box 1.

[0041] In this embodiment, a chassis 4 is fixedly mounted on the outer wall of the rice stone removing box 1, a driving motor 1511 is fixedly mounted on the inner wall of the chassis 4, a heat dissipation hole 5 is opened on the outer wall of the chassis 4, a controller 8 is provided on the upper side of the chassis 4, and the controller 8 is fixedly mounted on the outer wall of the rice stone removing box 1.

[0042] Through the above structure, the setting of the chassis 4 provides protection for the various driving components inside the chassis 4, and the opening of the heat dissipation holes 5 on the side wall of the chassis 4 improves the heat dissipation effect on the driving motor 1511.

[0043] In this embodiment, a back plate 2 is screwed onto the side of the rice stone removing box 1 , and positioning bolts 3 are screwed onto the four corners of the back plate 2 .

[0044] Through the above structure, the back plate 2 is screwed and installed on the side of the rice stone removing box 1, which is convenient for subsequent removal of the back plate 2 to inspect the internal components of the rice stone removing box 1.

[0045] In this embodiment, a feeding cylinder 9 is fixedly installed on the upper side of the rice stone removal box 1 , and the feeding cylinder 9 is communicated with the interior of the rice stone removal box 1 .

[0046] With the above structure, the rice to be processed can be added into the rice stone removing box 1 through the feeding cylinder 9 to perform stone removal.

[0047] In this embodiment, an air suction chamber 10 is installed on the upper side of the rice stone removal box 1, and an air suction pipe 11 is installed on the upper side of the air suction chamber 10. An air suction pump 12 is installed at the lower end of the air suction pipe 11, and a collecting box 13 is installed at the bottom of the air suction pump 12. The air outlet of the air suction pump 12 is connected to the inside of the collecting box 13, and a ventilation mesh plate is installed on the side of the collecting box 13.

[0048] Through the above structure, starting the vacuum pump 12 can generate a suction force in the suction chamber 10, and the gas blown out from the bottom blowing pipe 142 is sucked upward, reducing the probability of gas overflowing from the side waste outlet 6 and rice outlet 7, thereby reducing the occurrence of dust overflow during the rice de-stoning process.

[0049] In the present invention, when in use, the rice to be processed is added into the rice stone removing box 1 from the feeding barrel 9, and the driving motor 1511, the vacuum pump 12 and the blower pump 145 are started synchronously. Under the action of the driving motor 1511, the cam 1512 is driven to rotate, and the rebound force of the second spring 1513 causes the roller 1510 provided at the outer end of the center column 157 to always abut against the side of the cam 1512, and then with the rotation of the cam 1512, the center column 157 is driven to slide back and forth along the side of the rice stone removing box 1, thereby driving the inner mesh plate 151 to vibrate continuously inside the rice stone removing box 1, and at the same time, under the action of the blower pump 145, the air is blown upward by the blowing pipe 142, and then under the action of vibration and the blowing at the bottom of the mesh plate 151, the rice stone removing box 1 is continuously vibrated. The rice and the stones are separated by air and the difference in specific gravity between the rice and the stones is utilized to form a layered state on the mesh plate 151. The rice on the upper side slides down the inclined surface of the mesh plate 151 to the rice outlet 7 to be led out to the outside of the rice and stone box 1. The stones on the lower side of the mesh plate 151 fit the mesh plate and slide upward along the inclined surface of the mesh plate 151 under the action of vibration. Then they slide from the right end of the mesh plate 151 to the waste outlet 6 to be led out to the outside of the rice and stone box 1, thereby achieving the separation of the rice and the stones on the mesh plate 151. Under the action of the air pump 12, the air inside the rice and stone box 1 is sucked into the collection box 13 through the suction chamber 10 and the suction pipe 11. The ventilation mesh plate in the collection box 13 has a dust filtering effect, filtering the dust in the air into the collection box 13.
