Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand production, and particularly relates to a feeding device for quartz sand production. Background Technique

[0002] Quartz sand is a kind of mineral particle mainly composed of silicon dioxide, which is commonly found in natural areas such as rivers, beaches and deserts. Its particle shape is usually round or angular, and its surface is smooth. It has a variety of uses and wide applications, and is mainly used in industries such as building materials, glass products, electronics, filtration materials, chemical mining and artificial stone. Its characteristics include its hardness, wear resistance and chemical stability.

[0003] At present, the existing feeding device for quartz sand production uses a funnel for loading and continuously supplies materials to the feeding device. By rotating the screw inside the feeding device, the quartz sand is fed into the container. However, due to the uneven particle size of the quartz sand, during the feeding process, the smaller particles of quartz sand will get stuck between the screw and the inner wall. During the continuous rotation, it is easy to damage the inside of the feeding device and the screw, and a relatively large frictional sound will be generated, and it is necessary to stop the machine to clean the inside, and these problems cannot be quickly handled. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a feeding device for quartz sand production, which has the advantages of being able to quickly handle the stuck quartz sand, avoiding damage and large noise generation, etc., and solves the problems of the current feeding device. Due to the difference in the particle size of the quartz sand, the smaller particles of quartz sand are easily stuck on the inner wall of the device and the screw, resulting in the fact that during the continuous rotation for feeding, the quartz sand is easy to scratch the inner wall, causing damage to the screw and the inner wall, and generating a relatively large noise, and it is impossible to make a quick treatment.

[0006] (2) Technical Solution

[0007] To achieve the above object, the utility model provides the following technical solution: A feeding device for quartz sand production, including a feeding component and a driving component. The feeding component includes a feeding pipe, a feeding cavity is opened in the feeding pipe. At the same time, one end of the feeding pipe is fixed with a feeding funnel, and the other end is provided with a discharge interface. One end of the top of the feeding pipe is fixed with a feeding funnel, and the bottom end is provided with a discharge interface. Both the feeding funnel and the discharge interface communicate with the inside of the feeding pipe, so that the quartz sand is conveyed into the feeding pipe through the feeding funnel, and under operation, the quartz sand is discharged from the discharge interface for feeding.

[0008] The driving assembly includes a driving box movably connected to one end of the feeding pipe. A docking box is movably sleeved inside the driving box. A feeding screw is movably hinged on the docking box. At the same time, an installation box is fixed on the driving box. An electric telescopic rod is movably sleeved inside the installation box. The output end of the electric telescopic rod is fixed with a linkage plate. One end of the linkage plate is fixed with a linkage rod. One end of the linkage rod is fixed on the docking box. The feeding cavity penetrates through one end of the feeding pipe. The driving box fits against one end of the feeding pipe, so that the docking box is inserted into the interface of the feeding cavity to seal the interface. At the same time, two feeding screws are installed inside the docking box. When the feeding screws rotate, the quartz sand is conveyed from the tail end to the front end to the discharging interface for feeding. When the phenomenon of material jamming occurs, the electric telescopic rod extends to drive the docking box to move backward, so that the feeding screws telescopically move in the feeding cavity to handle the material jamming phenomenon.

[0009] As a further improvement of the above solution, a pneumatic telescopic rod is fixed on the side of the feeding pipe, and the output end of the pneumatic telescopic rod is fixed on the driving box.

[0010] Through the above technical solution, the pneumatic telescopic rod telescopically moves, so that the driving box fits against one end of the feeding pipe to seal the feeding cavity or disengages from the feeding pipe, exposing the feeding cavity, which is convenient for cleaning the cavity and the feeding screws.

[0011] As a further improvement of the above solution, a stabilizing sleeve rod is fixed inside the driving box. A limiting button is fixed at one end of the stabilizing sleeve rod. The stabilizing sleeve rod is movably sleeved inside the docking box, and at the same time, the limiting button fits against the docking box.

[0012] Through the above technical solution, when the output end of the electric telescopic rod telescopically moves, the docking box moves inside the driving box and slides on the side of the stabilizing sleeve rod, improving the stability of the movement of the docking box, and limiting the telescopic distance of the docking box through the limiting button to prevent the docking box from disengaging from the driving box.

[0013] As a further improvement of the above solution, a stabilizing groove is opened inside the docking box. A driving gear and a transmission gear are movably sleeved inside the stabilizing groove, and the two gears mesh, and are fixed at one end of the feeding screw at the same time.

[0014] Through the above technical solution, when the driving gear rotates, under the action of the meshing force of the side gear teeth, the transmission gear rotates in the opposite direction, so that the two feeding screws rotate towards the middle to convey the quartz sand.

[0015] As a further improvement of the above solution, a driving motor is fixed on the docking box, and the output end of the driving motor is fixed on the driving gear.

[0016] Through the above technical solution, the driving motor is used as the driving source. When the driving motor operates, its output end drives the driving gear to rotate.

[0017] As a further improvement of the above solution, a locking rod is threadedly connected to the side of the installation box, and one end of the locking rod is attached to the side of the electric telescopic rod.

[0018] Through the above technical solution, when the locking rod is rotated clockwise, its front end gradually moves inward and closely adheres to the side of the electric telescopic rod. When the locking rod is rotated counterclockwise, its output end gradually moves backward and disengages from the side of the electric telescopic rod. At this time, the electric telescopic rod can be taken out and replaced.

[0019] As a further improvement of the above solution, a rubber ring is fixed at the interface of the drive box, and the rubber ring is attached to the side of the docking box.

[0020] Through the above technical solution, the rubber ring is used to increase the sealing performance between the drive box and the docking box, prevent small quartz sand particles from getting stuck in the gap, and avoid the situation where the docking box cannot be telescoped in the drive box.

[0021] Compared with the prior art, the present utility model provides a feeding device for quartz sand production, which has the following beneficial effects:

[0022] 1. In the feeding device for quartz sand production, a docking box is movably sleeved in the drive box, a feeding screw is installed on the docking box, and an electric telescopic rod is arranged on the side of the drive box. When the phenomenon of quartz sand jamming occurs, the output end of the electric telescopic rod expands and contracts, and drives the linkage rod to operate simultaneously through the linkage plate, so that the docking box expands and contracts in the drive box, and the installed feeding screw moves back and forth in the feeding cavity, thereby effectively separating the jammed quartz sand particles, avoiding damage and noise, and effectively preventing the device from being damaged.

[0023] 2. In the feeding device for quartz sand production, a pneumatic telescopic rod is installed on the side of the feeding pipe, and the output end of the pneumatic telescopic rod is fixed on the drive box. By expanding and contracting the output end, the drive box drives the docking box to close or disengage from one end of the feeding pipe. When disengaged, the feeding screw is withdrawn from the feeding cavity, facilitating the maintenance and cleaning of the cavity and the feeding screw, and further improving its practicability.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment 1

[0033] Please refer to Figures 1-4 As shown, the feeding device for quartz sand production proposed in this embodiment includes a feeding assembly 1 and a driving assembly 2. The feeding assembly 1 includes a feeding pipe 101. A feeding cavity 102 is provided inside the feeding pipe 101. At the same time, a feeding funnel 103 is fixed at one end of the feeding pipe 101, and a discharge interface 104 is provided at the other end. The feeding funnel 103 is fixed at one end of the top of the feeding pipe 101, and the discharge interface 104 is provided at one end of the bottom. Both the feeding funnel 103 and the discharge interface 104 communicate with the inside of the feeding pipe 101, so that quartz sand is conveyed into the feeding pipe 101 through the feeding funnel 103, and under operation, the quartz sand is discharged from the discharge interface 104 for feeding.

[0034] The driving assembly 2 includes a driving box 201 movably connected to one end of the feeding pipe 101. A docking box 202 is movably sleeved inside the driving box 201. A feeding screw 208 is movably hinged on the docking box 202. At the same time, an installation box 210 is fixed on the driving box 201. An electric telescopic rod 211 is movably sleeved inside the installation box 210. The output end of the electric telescopic rod 211 is fixed with a linkage plate 213. One end of the linkage plate 213 is fixed with a linkage rod 214. One end of the linkage rod 214 is fixed on the docking box 202. The feeding cavity 102 penetrates through one end of the feeding pipe 101. The driving box 201 fits against one end of the feeding pipe 101, so that the docking box 202 is inserted into the interface of the feeding cavity 102 to seal the interface. At the same time, two feeding screws 208 are installed inside the docking box 202. When the feeding screws 208 rotate, the quartz sand is conveyed from the tail end to the front end to the discharging interface 104 for feeding. When the phenomenon of material jamming occurs, the electric telescopic rod 211 extends to drive the docking box 202 to move backward, so that the feeding screw 208 telescopically moves in the feeding cavity 102 to handle the material jamming phenomenon.

[0035] The working principle of the feeding device for quartz sand production proposed in this embodiment is as follows: When in use, pour the quartz sand into the feeding funnel 103, and control the operation of the driving motor 209, so that the driving gear 206 rotates. Under the action of gear tooth meshing, the transmission gear 207 rotates in the reverse direction, so that the two feeding screws 208 rotate towards the middle to convey the quartz sand forward. When the quartz sand reaches the discharging interface 104, it is output from the discharging interface 104 and fed into the next processing device. When material jamming occurs during the feeding of the quartz sand, control the operation of the electric telescopic rod 211 (at this time, the driving motor 209 stops operating), so that its output end drives the linkage plate 213 to move back and forth, and drives the docking box 202 to telescopically move simultaneously through the linkage rod 214, so that the feeding screw 208 telescopically moves back and forth in the feeding cavity 102 to push the jammed quartz sand into the normal conveying space. Then control the output end of the electric telescopic rod 211 to reset, and control the driving motor 209 to operate to continue feeding.

[0036] Further, a pneumatic telescopic rod 105 is fixed on the side of the feeding pipe 101, and the output end of the pneumatic telescopic rod 105 is fixed on the driving box 201.

[0037] Specifically, the pneumatic telescopic rod 105 telescopically moves, so that the driving box 201 fits against one end of the feeding pipe 101 to seal the feeding cavity 102 or separates from the feeding pipe 101 to expose the feeding cavity 102, which is convenient for cleaning the cavity and the feeding screw 208.

[0038] Further, a stabilizing sleeve rod 203 is fixed inside the driving box 201. A limiting button 204 is fixed at one end of the stabilizing sleeve rod 203. The stabilizing sleeve rod 203 is movably sleeved inside the docking box 202, and at the same time, the limiting button 204 is attached to the docking box 202.

[0039] More specifically, when the output end of the electric telescopic rod 211 expands and contracts, the docking box 202 moves inside the driving box 201 and slides on the side of the stabilizing sleeve rod 203 at the same time, improving the stability of the movement of the docking box 202, and limiting the telescopic distance of the docking box 202 through the limiting button 204 to prevent the docking box 202 from detaching from the driving box 201.

[0040] Further, a stabilizing groove 205 is formed inside the docking box 202. A driving gear 206 and a transmission gear 207 are movably sleeved inside the stabilizing groove 205, and the two gears are meshed. At the same time, one end of the feeding screw rod 208 is fixed.

[0041] More specifically, when the driving gear 206 rotates, under the acting force of meshing with the side gear teeth, the transmission gear 207 rotates in the opposite direction, causing the two feeding screw rods 208 to rotate towards the middle, achieving the effect of conveying quartz sand.

[0042] Further, a driving motor 209 is fixed on the docking box 202, and the output end of the driving motor 209 is fixed on the driving gear 206.

[0043] More specifically, the driving motor 209 serves as a driving source. When the driving motor 209 operates, its output end drives the driving gear 206 to rotate.

[0044] Further, a locking rod 212 is threadedly connected to the side of the installation box 210, and one end of the locking rod 212 is attached to the side of the electric telescopic rod 211.

[0045] More specifically, when the locking rod 212 is rotated clockwise, its front end gradually moves inward and closely adheres to the side of the electric telescopic rod 211. When the locking rod 212 is rotated counterclockwise, its output end gradually moves backward and disengages from the side of the electric telescopic rod 211. At this time, the electric telescopic rod 211 can be taken out and replaced.

[0046] Further, a rubber ring 215 is fixed at the interface of the driving box 201, and the rubber ring 215 is attached to the side of the docking box 202.

[0047] More specifically, the rubber ring 215 is used to increase the sealing performance between the driving box 201 and the docking box 202, preventing small particles of quartz sand from getting stuck in the gap and causing the docking box 202 to be unable to expand and contract inside the driving box 201.

[0048] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
