[0036] As shown Figures 1-11 in the figure, a lifting and conveying device for quartz stone processing includes:

[0037] A base 10, a support frame 110, a conveyor belt 120, a first roller 130, a second roller 140, and a third roller 150; the support frame 110 is arranged on the base 10, the first roller 130, the second roller 140, and the third roller 150 are arranged on the support frame 110, the conveyor belt 120 is sleeved on the first roller 130, the second roller 140, and the third roller 150, baffles 121 are arranged on both sides of the conveyor belt 120, a material supporting plate 122 is arranged on the conveyor belt surface of the conveyor belt 120, a plurality of material supporting plates 122 are provided and are evenly spaced along the conveying direction of the conveyor belt 120, a filter plate 123 is arranged on the plate surface of the material supporting plate 122, the filter plate 123 is parallel to the conveyor belt surface of the conveyor belt 120, a cleaning and impurity removing mechanism 20 for removing impurities from quartz stone is arranged on the material supporting plate 122, a collecting housing 30 is arranged below the conveyor belt surface of the conveyor belt 120, the collecting housing 30 is a cuboid housing with an open top, the open end of the collecting housing 30 faces the conveyor belt surface of the conveyor belt 120 and is in close contact with the conveyor belt surface of the conveyor belt 120, a connecting pipe 310 is connected to the bottom of the collecting housing 30, and a blower 330 is arranged at the discharging port of the connecting pipe 310.

[0038] As shown Figures 4-11 in the figure, the material supporting plate 122 is a hollow structure and is a cuboid housing with an open bottom, discharging grooves 125 are formed on the conveyor belt surface of the conveyor belt 120, a plurality of discharging grooves 125 are provided and are evenly spaced along the conveyor belt surface of the conveyor belt 120, the open bottom end of the material supporting plate 122 is in matching communication with the discharging grooves 125 of the conveyor belt 120, the cleaning and impurity removing mechanism 20 is arranged on the wall of the material supporting plate 122, multiple groups of cleaning and impurity removing mechanisms 20 are provided and are evenly spaced along the length direction of the material supporting plate 122, the cleaning and impurity removing mechanism 20 includes a turning plate 210, a transmission mechanism 220, and a connecting shaft 230, the connecting shaft 230 is a hollow structure with one end closed and the other end open, the open end of the connecting shaft 230 passes through the wall of the material supporting plate 122 and extends into the material supporting plate 122, the closed end of the connecting shaft 230 extends away from the material supporting plate 122, the connecting shaft 230 is parallel to the conveying direction of the conveyor belt 120, the turning plate 210 is arranged on the circumference of the connecting shaft 230, a plurality of turning plates 210 are provided and are evenly distributed around the circumference of the connecting shaft 230, the turning plate 210 is close to the filter plate 123, the turning plate 210 is a hollow plate body, the turning plate 210 is in communication with the wall of the connecting shaft 230, and a plurality of feeding holes 214 are formed on the plate surface of the turning plate 210 and are evenly spaced. The transmission mechanism 220 is arranged at the inner wall of the material supporting plate 122.

[0039] More specifically, the transmission mechanism 220 includes a first support plate 221, a second support plate 222, guide columns 223, a rack 224, a push rod 225, and a gear 226. The first support plate 221 and the second support plate 222 are arranged at the inner wall of the material supporting plate 122. The guide columns 223 are connected between the first support plate 221 and the second support plate 222. There are two guide columns 223 arranged in parallel. The guide columns 223 are parallel to the inner wall of the material supporting plate 122. The rack 224 is sleeved on the guide columns 223 through a sliding sleeve. A first spring is sleeved on the guide columns 223. One end of the first spring contacts the first support plate 221, and the other end of the first spring contacts the sliding sleeve. The gear 226 is coaxially and fixedly sleeved on the open end of the connecting shaft 230. The gear 226 meshes with the rack 224. The push rod 225 is fixedly connected to the bottom of the rack 224. The push rod 225 is parallel to the guide columns 223. The bottom end of the push rod 225 is conical. In the initial state, the bottom end of the push rod 225 extends out of the open end of the material supporting plate 122. A trigger rod 340 is fixedly arranged at the open end of the collection housing 30. There are multiple trigger rods 340 arranged at uniform intervals along the length direction of the collection housing 30. When lifting and conveying the quartz stone, the quartz stone is located between two adjacent material supporting plates 122. During the conveying process of the conveyor belt 120, the conical bottom end of the push rod 225 touches the trigger rod 340 at the open end of the collection housing 30, thereby driving the push rod 225 to move upward. Then, the rack 224 moves upward along the guide columns 223, thereby driving the gear 226 and the connecting shaft 230 to rotate, thereby driving the turning plate 210 to rotate, so as to turn the quartz stone, which can facilitate the dispersion of the dust mixed in the quartz stone. When the push rod 225 passes over the trigger rod 340, the elastic force of the first spring pushes the rack 224 to move downward along the guide columns 223, so that the connecting shaft 230 can rotate reciprocally, thereby driving the turning plate 210 to rotate reciprocally, improving the turning effect on the quartz stone. When turning the quartz stone, the fan 330 works to extract air from the collection housing 30. When the material supporting plate 122 is conveyed above the collection housing 30, air can be extracted from the inside of the material supporting plate 122, thereby extracting air from the inside of the connecting shaft 230. The dust enters the inside of the turning plate 210 through the feed holes 214 on the surface of the turning plate 210, then enters the inside of the material supporting plate 122 through the connecting shaft 230, and then enters the collection housing 30, and is discharged through the connecting pipe 310.

[0040] Such as Figures 9-11As shown in the figure, guide rods 211 are arranged inside the turnover plate 210. There are multiple guide rods 211 arranged in parallel. The guide rods 211 are perpendicular to the plate surface of the turnover plate 210. A push plate 212 is sleeved on the guide rods 211. Crushing rods 213 are arranged on the plate surface of the push plate 212. The crushing rods 213 are parallel to the guide rods 211. There are multiple crushing rods 213 arranged at uniform intervals. Both ends of the crushing rods 213 pass through the feeding holes 214 on the turnover plate 210. Both ends of the crushing rods 213 are tapered. A second spring is sleeved on the guide rods 211. One end of the second spring contacts the inner wall of the turnover plate 210, and the other end of the second spring contacts the plate surface of the push plate 212. During the process of the turnover plate 210 turning over the quartz stone, the end of the crushing rod 213 can contact the mud block in the quartz stone, so as to break the mud block. When the turnover plate 210 turns over, the quartz stone contacts the end of the crushing rod 213, so as to drive the push plate 212 to reciprocate along the guide rod 211, and the crushing rod 213 reciprocates inside the turnover plate 210. Therefore, the feeding holes 214 on the turnover plate 210 can be opened, and the crushed mud blocks can be sucked into the inside of the turnover plate 210 through the feeding holes 214.

[0041] As Figures 1-2 shown, the second roller 140 is directly above the first roller 130. Mounting blocks two 141 are rotatably connected to both ends of the second roller 140. Mounting blocks one 131 are rotatably connected to both ends of the first roller 130. Connecting columns 132 are vertically arranged at the tops of the mounting blocks one 131. There are two connecting columns 132. Connecting sleeves 133 are vertically arranged at the bottoms of the mounting blocks two 141. The connecting sleeves 133 are sleeved on the connecting columns 132. A third spring is sleeved outside the connecting sleeves 133. A support plate one 160 is arranged at the top end of the support frame 110. Support plates two 170 are rotatably connected to both ends of the third roller 150. A pushing component 180 (which is a prior art and will not be elaborated too much) is arranged at the upper end of the support plate one 160. The top end of the pushing component 180 is connected to the bottom end of the support plate two 170. The pushing component 180 can move the third roller 150 away from the second roller 140, and move the first roller 130 towards the second roller 140, so as to adjust the conveying length of the conveyor belt 120.

[0042] More specifically, a motor 111 is arranged at the top of the support frame 110. The output shaft of the motor 111 is horizontally arranged. The lower plate surface of the support plate one 160 is fixedly sleeved on the output shaft end of the motor 111. The motor 111 can drive the support plate one 160 to deflect, so as to adjust the lifting and conveying angle of the conveyor belt 120.

[0043] As Figure 3As shown, a collection box 320 is provided at the discharge port of the connecting pipe 310. A filter plate for filtering dust is provided inside the collection box 320, so that the dust in the quartz stone can be centrally collected in the collection box 320.

[0044] More specifically, a guiding block 124 is provided on the top plate surface of the filter plate 123. The guiding block 124 is close to the upper end of the filter plate 123. The quartz stone is located between the material supporting plate 122 and the guiding block 124. The end face of the guiding block 124 in contact with the quartz stone is arranged obliquely, so as to facilitate guiding the large-particle quartz stone above the filter plate 123 to fall, and the large-particle quartz stone falls from one side of the conveying end of the conveyor belt 120. The small-particle quartz stone between the filter plate 123 and the conveyor belt surface of the conveyor belt 120 falls from the conveying end of the conveyor belt 120, so as to facilitate screening and sub-packaging of the large-particle quartz stone and the small-particle quartz stone.

[0045] Working principle:

[0046] During the use of the present invention, when lifting and conveying quartz stone, the quartz stone is located between two adjacent material supporting plates 122. During the conveying process of the conveyor belt 120, the conical bottom end of the ejector rod 225 touches the trigger rod 340 at the opening end of the collection housing 30, thereby driving the ejector rod 225 to move upward. Then, the rack 224 moves upward along the guide post 223, thereby driving the gear 226 and the connecting shaft 230 to rotate, and then driving the turning plate 210 to rotate, so as to turn the quartz stone, which can facilitate the dispersion of the dust mixed in the quartz stone. When the ejector rod 225 passes over the trigger rod 340, the elastic force of the first spring pushes the rack 224 to move downward along the guide post 223, so that the connecting shaft 230 can rotate reciprocally, and then drive the turning plate 210 to rotate reciprocally, improving the turning effect on the quartz stone. When turning the quartz stone, the fan 330 works to extract air from the collection housing 30. When the material supporting plate 122 is conveyed above the collection housing 30, the inside of the material supporting plate 122 can be extracted, and then the inside of the connecting shaft 230 can be extracted. The dust enters the inside of the turning plate 210 through the feed holes 214 on the surface of the turning plate 210, then enters the inside of the connecting shaft 230 through the connecting shaft 230, then enters the inside of the material supporting plate 122, and then enters the collection housing 30, and is discharged through the communicating pipe 310. During the process of the turning plate 210 turning the quartz stone, the end of the crushing rod 213 can contact the mud block in the quartz stone to crush the mud block. When the turning plate 210 flips, the quartz stone contacts the end of the crushing rod 213, which can drive the push plate 212 to move reciprocally along the guide rod 211, and the crushing rod 213 moves reciprocally inside the turning plate 210. Therefore, the feed holes 214 on the turning plate 210 can be opened, and the crushed mud blocks can be sucked into the inside of the turning plate 210 through the feed holes 214. The pushing component 180 can move the third roller 150 away from the second roller 140 and move the first roller 130 closer to the second roller 140, so as to adjust the conveying length of the conveyor belt 120. The filter plate 123 screens large and small particle quartz stones. When conveying the quartz stone, the guiding block 124 guides the large particle quartz stones above the filter plate 123 to fall, and the large particle quartz stones fall from one side of the conveying end of the conveyor belt 120. The small particle quartz stones between the filter plate 123 and the conveyor belt surface of the conveyor belt 120 fall from the conveying end of the conveyor belt 120, which is convenient for screening and packaging large particle quartz stones and small particle quartz stones.
