[0002] When the fruit and vegetable dry matter is crushed into fruit and vegetable powder by a crusher, at the end of feeding, since there will be a certain residue of the fruit and vegetable powder in the crusher, and because the light fruit and vegetable powder will generate dust, when the storage device at the bottom is separated from the feeding port of the crusher, the fruit and vegetable powder remaining at the bottom of the crusher will fall, and the fruit and vegetable powder accumulated on the top of the storage device will generate dust, thus causing waste of the fruit and vegetable powder.

[0003] Moreover, since both the feeding port of the crusher and the opening of the storage device are in an open state, impurities in the air will contaminate the fruit and vegetable powder on the surface, affecting the quality of the fruit and vegetable powder. And the dusted fruit and vegetable powder entering the air will increase the powder content in the air, and will also cause pollution to the working environment, which will affect the physical health of workers in the long-term working environment. Summary of the Invention

[0004] The present invention discloses a feeding device for fruit and vegetable powder processing, aiming to solve the technical problems that since both the feeding port of the crusher and the opening of the storage device are in an open state, impurities in the air will contaminate the fruit and vegetable powder on the surface, affecting the quality of the fruit and vegetable powder, and the dusted fruit and vegetable powder entering the air will increase the powder content in the air, and will also cause pollution to the working environment, which will affect the physical health of workers in the long-term working environment.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The feeding blocking mechanism includes two elastic cloth rings, and elastic rings are respectively connected to the top and bottom of each elastic cloth ring. The bottom of the crusher is fixedly connected with a feeding pipe, and a plurality of annular protrusions are equidistantly arranged on the outer wall of the feeding pipe. The two elastic cloth rings are stacked and wound around the outside of the feeding pipe. An air rod is installed on the outer wall of one side of the crusher, and the output end of the air rod is fixedly connected with a connecting plate. The connecting plate surrounds the outside of the feeding pipe, and two ends of the connecting plate are respectively fixedly connected with a damping hinge bracket I. Two pressing blocks I are respectively hinged on each damping hinge bracket I, and the bottom ends of the two pressing blocks I respectively press on the two elastic rings on the upper elastic cloth ring;

[0008] The storage cylinder includes a top cover, and a second material passing pipe is fixedly connected to the inner wall of the top end of the top cover. The outer wall of the second material passing pipe is movably fitted to the inner wall of the material discharging pipe, and a limiting edge is fixedly connected around the outer wall of the second material passing pipe. The limiting edge is movably embedded in the inner wall of the bottom end of the material discharging pipe. A plurality of damping hinge frames II are fixedly connected to the top end of the top cover, and a second pressing block is hinged to each damping hinge frame II. The second pressing block presses between two elastic cloth rings. The bottom adjusting mechanism includes a lift.

[0009] By providing a material discharging blocking mechanism, when the material discharging pipe is connected to the second material passing pipe, the elastic ring at the bottom of the lower elastic cloth ring can be pulled down and clamped to the bottom of the limiting edge, and the elastic ring at the top thereof remains on the material discharging pipe. Manually press the damping hinge frame II to press it against the top end of the elastic ring. The upper elastic cloth ring surrounds the material discharging pipe, and manually press two first pressing blocks to press them against the two elastic rings of the elastic cloth ring respectively. When the material discharging of the crusher ends, during the process of the lift driving the storage cylinder to descend, the elastic ring above the elastic cloth ring at the bottom end quickly contracts, so that the elastic cloth ring is tightened on the top end of the second material passing pipe, and the elastic ring at the bottom of the upper elastic cloth ring is separated from the material discharging pipe, so that the elastic cloth ring is tightened on the bottom end of the material discharging pipe, blocking the residual fruit and vegetable powder inside the crusher. Thus, it can avoid the waste caused by the raising of fruit and vegetable powder during the material discharging process, prevent the pollution of fruit and vegetable powder by impurities in the air, and at the same time, by suppressing the dust of fruit and vegetable powder, reduce the powder content in the air, optimize the air quality, and play a role in improving the working environment.

[0010] In a preferred solution, a plurality of limiting insertion rods are fixedly connected to the outer wall of the crusher, and the limiting insertion rods are movably inserted into the connecting plate. A plurality of side support columns are fixedly connected to the outer wall of the crusher, and the bottom ends of the plurality of side support columns are fixedly connected to a base at the same time. The bottom adjusting mechanism is arranged at the top end of the base;

[0011] The storage cylinder further includes a cylinder body, and the top cover covers the top end of the cylinder body. An elastic cylinder body is fixedly connected to the bottom end of the cylinder body, and a cylinder bottom is fixedly connected to the bottom end of the elastic cylinder body. A plurality of second support plates are fixedly connected to the outer wall of the cylinder bottom at equal intervals, and a threaded rod is fixedly connected to the top end of each second support plate. A threaded pipe is sleeved outside each threaded rod;

[0012] A plurality of first support plates are fixedly connected to the outer wall of the cylinder body at equal intervals, and the positions of the plurality of first support plates correspond to those of the plurality of threaded pipes and the second support plates. The outer wall of the top end of each threaded pipe is provided with an external thread, and a threaded hole is respectively arranged on the inner wall of the bottom end of each first support plate. The plurality of threaded pipes are correspondingly meshed in the threaded holes through the external threads. The bottom adjusting mechanism includes a fourth support plate, and the lift is arranged between the fourth support plate and the base. An arc-shaped driving track is fixedly connected to the outer wall of the top end of the fourth support plate, and a slider is movably connected in the arc-shaped driving track;

[0013] The top end of the slider is fixedly connected with an arc-shaped support seat, and the top end of the arc-shaped support seat is fixedly connected with a third support plate. The top end of the third support plate is fixedly connected with a limiting ring, and the bottom of the cylinder is clamped in the limiting ring. The middle section of each side support column is provided with a clamping interface, and a second limiting plate is movably sleeved at each clamping interface.

[0014] By providing a bottom adjusting mechanism, when the elevator raises the storage cylinder, laterally moving the second limiting plate can provide support for the bottom end of the first support plate. At this time, the threaded pipe can be manually rotated to drive it to descend, so that it disengages from the support of the first support plate. Since the bottom of the cylinder is clamped in the limiting ring, while the arc-shaped driving track drives the arc-shaped support seat to reciprocate, during the powder discharging process of the pulverizer, the powder is evenly distributed in the bottom of the cylinder, avoiding the accumulation of fruit and vegetable powder inside the storage cylinder and affecting the normal falling of the fruit and vegetable powder when the storage cylinder is not full.

[0015] In a preferred solution, the feeding mechanism includes a support housing. The inner wall of the top end of the support housing is fixedly connected with a feeding funnel, and an intermittent valve is arranged at the connection between the feeding funnel and the support housing. The inner wall of the bottom end of the support housing is fixedly connected with a first through pipe, and the first through pipe is connected to the feeding port of the pulverizer. The inner walls of the top and bottom ends of the support housing are fixedly connected with elastic sleeves, and the connections between the feeding funnel and the support housing and between the first through pipe and the support housing are both located inside the elastic sleeves;

[0016] A plurality of first limiting plates are fixedly connected to the inner wall of the support housing. The plurality of first limiting plates are divided into two groups and are symmetrically distributed on both sides of the elastic sleeve. Longitudinal pressing plates are respectively arranged on the same sides of the elastic sleeve, and each group of first limiting plates is movably attached to the top and bottom ends of the longitudinal pressing plates. A plurality of conical pressing strips are respectively fixedly connected to the inner sides of the two longitudinal pressing plates, and the conical pressing strips on the two longitudinal pressing plates are arranged in a staggered manner;

[0017] Support rods are respectively fixedly connected to the outer sides of the two longitudinal pressing plates, and the support rods pass through the support housing. The outer ends of the two support rods are simultaneously fixedly connected with a double-headed hydraulic rod, and the double-headed hydraulic rod is installed on one side of the support housing. Two L-shaped bottom plates are symmetrically and fixedly connected to the inner wall of the bottom end of the support housing, and a transverse pressing plate is movably clamped between each L-shaped bottom plate on each side and the limiting plate;

[0018] A first rack is respectively fixedly connected to the outer side of each longitudinal pressing plate, and a notch is arranged at one end of the first rack. A first large-diameter gear is meshed with one side of the first rack, and a small-diameter gear is meshed with one side of the first large-diameter gear. A second large-diameter gear is arranged on one side of the small-diameter gear, and the first large-diameter gear, the second large-diameter gear and the small-diameter gear are simultaneously rotatably connected to the L-shaped bottom plate;

[0019] The bottom ends of the large-diameter gear II and the small-diameter gear respectively pass through the L-shaped bottom plate and are fixedly connected with synchronous wheels, and a synchronous belt is sleeved on the two synchronous wheels at the same time. One side of the large-diameter gear II meshes with a rack II, and the rack II is fixed on the top outer wall of the transverse extrusion plate. A through groove is arranged through the transverse extrusion plate, and the large-diameter gear I, the large-diameter gear II and the small-diameter gear are located in the through groove.

[0020] By providing a feeding mechanism, in the feeding mechanism, large pieces of dried fruits and vegetables enter the elastic sleeve from the feeding funnel, and intermittent feeding is realized by the intermittent opening and closing of the intermittent valve. When the dried fruits and vegetables enter the elastic sleeve and the intermittent valve is closed, the double-headed hydraulic rod drives the longitudinal extrusion plates on both sides to move inward to slightly squeeze the dried fruits and vegetables in the elastic sleeve, and drives the two transverse extrusion plates to move correspondingly, so that the top of the material-passing pipe I is in a fully open state. In this structure, batch feeding of dried fruits and vegetables to the crusher can be realized. At the same time, during the feeding process, the preliminary crushing of the dried fruits and vegetables is realized by the extrusion of the conical extrusion strips on the longitudinal extrusion plates. Thus, through the methods of preliminary crushing and batch feeding, the accumulation and retention of dried fruits and vegetables in the material-passing pipe I can be avoided, and the dried fruits and vegetables after preliminary crushing are also convenient for subsequent crushing, which can optimize the crushing efficiency. At the same time, based on the setting of the elastic sleeve, the falling of dried fruit fragments into the support shell can be avoided, the waste of raw materials can be avoided, and the cleaning of the internal space is also convenient. And through the buffering of the elastic sleeve, during the process of slight extrusion and crushing, the generation of smaller fragments can be reduced, further ensuring that the sizes of the dried fruits and vegetables entering the crusher tend to be average and ensuring the crushing effect.

The top of the top cover 401 is fixedly connected with a plurality of damping hinge frames 404, and each damping hinge frame 404 is hinged with a pressure block 405, and the pressure block 405 is pressed between the two elastic cloth rings 308. The bottom adjustment mechanism 5 includes a lifter 506. When the feed tube 8 is connected to the feed tube 406, the elastic ring 307 at the bottom of the lower elastic cloth ring 308 can be pushed down and connected to the bottom of the limiting edge 407, and the elastic ring 307 at the top is retained on the feed tube 8.

[0036] Refer to Figure 2 , in a preferred embodiment, a plurality of limiting insertion rods 303 are fixedly connected to the outer wall of the crusher 2, and the limiting insertion rods 303 are movably inserted into the connecting plate 302. A plurality of side support columns 7 are fixedly connected to the outer wall of the crusher 2, and the bottoms of the plurality of side support columns 7 are fixedly connected to the base 6 at the same time. The bottom adjusting mechanism 5 is arranged at the top of the base 6.

[0037] Refer to Figure 4 , in a preferred embodiment, the storage cylinder 4 further includes a cylinder body 402, and the top cover 401 covers the top of the cylinder body 402. A resilient cylinder body 411 is fixedly connected to the bottom of the cylinder body 402, and a cylinder bottom 412 is fixedly connected to the bottom of the resilient cylinder body 411. A plurality of second support plates 410 are equidistantly and fixedly connected to the outer wall of the cylinder bottom 412, and a threaded rod 409 is fixedly connected to the top of each second support plate 410. A threaded tube 408 is sleeved outside each threaded rod 409.

[0038] Refer to Figure 4 and Figure 5 , in a preferred embodiment, a plurality of first support plates 403 are equidistantly and fixedly connected to the outer wall of the cylinder body 402, and the positions of the plurality of first support plates 403 correspond to those of the plurality of threaded tubes 408 and the second support plates 410. External threads are provided on the outer wall of the top of each threaded tube 408, and screw holes are provided on the inner wall of the bottom of each first support plate 403. The plurality of threaded tubes 408 are correspondingly meshed in the screw holes through the external threads. The bottom adjusting mechanism 5 includes a fourth support plate 505, and a lifter 506 is arranged between the fourth support plate 505 and the base 6. An arc-shaped driving track 504 is fixedly connected to the outer wall of the top of the fourth support plate 505, and a slider 509 is movably connected in the arc-shaped driving track 504.

Each group of first limiting plates 105 is respectively movably attached to the top and bottom ends of the longitudinal pressing plates 106. A plurality of tapered pressing strips 107 are respectively fixedly connected to the inner sides of the two longitudinal pressing plates 106, and the tapered pressing strips 107 on the two longitudinal pressing plates 106 are arranged in a staggered manner.

The outer ends of the two support rods 104 are simultaneously fixedly connected to a double-headed hydraulic rod 112, and the double-headed hydraulic rod 112 is installed on one side of the support housing 103. Two L-shaped bottom plates 111 are symmetrically and fixedly connected to the inner wall of the bottom end of the support housing 103, and a transverse pressing plate 108 is movably clamped between each L-shaped bottom plate 111 on each side and the limiting plate 105.

[0043] Refer to Figure 7 and Figure 8 , in a preferred embodiment, a first rack 113 is respectively fixedly connected to the outer side of each longitudinal pressing plate 106, and a notch 114 is arranged at one end of the first rack 113. A large-diameter first gear 115 is meshed with one side of the first rack 113, and a small-diameter gear 116 is meshed with one side of the large-diameter first gear 115.

In the feeding mechanism 1, large pieces of dried fruits and vegetables enter the elastic sleeve 109 from the feeding hopper 101, and intermittent feeding is realized by the intermittent opening and closing of the intermittent valve 102 during the discharging process. When the dried fruits and vegetables enter the elastic sleeve 109 and the intermittent valve 102 is closed, the double-headed hydraulic rod 112 drives the longitudinal extrusion plates 106 on both sides to move inward to slightly extrude the dried fruits and vegetables in the elastic sleeve 109. At this time, the two transverse extrusion plates 108 clamp the bottom of the elastic sleeve 109, close the material-passing pipe I 110, and the large-diameter gear I 115 is located outside the rack I 113 and at the notch 114, so that the movement of the longitudinal extrusion plate 106 will not affect the position of the transverse extrusion plate 108. Then, the double-headed hydraulic rod 112 extends the outward pulling distance, expands the distance between the two longitudinal extrusion plates 106, and the position of the longitudinal extrusion plate 106 is farther than the initial distance. At this time, the rack I 113 just meshes with the large-diameter gear I 115. During the backward movement, the rotation speed of the gears is doubled through the meshing of the large-diameter gear I 115 and the small-diameter gear 116. Then, through the two synchronous pulleys 117 under the action of the synchronous belt 118, the small-diameter gear 116 and the large-diameter gear II 119 rotate in the same direction and at the same speed, further driving the rack II 120 to move with the characteristics of the same moving direction as the rack I 113 and a moving distance better than that of the rack I 113. Thus, while the longitudinal extrusion plate 106 moves outward for a short distance, it drives the two transverse extrusion plates 108 to move outward for a long distance, making the top end of the material-passing pipe I 110 in a fully open state. When the two longitudinal extrusion plates 106 return to the initial position, the two transverse extrusion plates 108 squeeze and close the bottom end of the elastic sleeve 109 again. In this structure, the batch feeding of dried fruits and vegetables to the crusher 2 can be realized. At the same time, during the feeding process, the preliminary crushing of the dried fruits and vegetables is realized through the extrusion of the conical extrusion strips 107 on the longitudinal extrusion plates 106. Thus, through the preliminary crushing and batch feeding methods, the accumulation and retention of dried fruits and vegetables in the material-passing pipe I 110 are avoided, and the preliminarily crushed dried fruits and vegetables are also convenient for subsequent crushing, which can optimize the crushing efficiency. At the same time, based on the setting of the elastic sleeve 109, the falling of crushed dried fruits and vegetables into the support housing 103 can be avoided, the waste of raw materials can be avoided, and the cleaning of the internal space is also convenient. Moreover, through the buffering of the elastic sleeve 109, during the process of slight extrusion and crushing, the generation of smaller fragments can be reduced, further ensuring that the sizes of the dried fruits and vegetables entering the crusher 2 tend to be average and ensuring the crushing effect.

[0045] Working principle: when the feeding tube 8 is connected to the feeding tube 2 406, the elastic ring 307 at the bottom of the lower elastic cloth ring 308 can be pushed down and clamped on the bottom of the limiting edge 407, and the elastic ring 307 at the top is retained on the feeding tube 8. The damping hinge frame 2 404 is manually pressed to press it on the top of the elastic ring 307, and the elastic cloth ring 308 at the top surrounds the feeding tube 8, and the two pressing blocks 1 306 are manually pressed to press them on the two elastic rings 307 of the elastic cloth ring 308 respectively. When the crusher 2 finishes unloading, the elevator 506 drives the storage cylinder 4 to descend. At this time, the gas rod 301 pushes the multiple groups of pressing blocks 1 306 to press down a short distance, and the elastic ring 307 at the bottom of the elastic cloth ring 308 at the bottom is clamped on the limiting edge 407. During the descending process of the storage cylinder 4 In the process, the elastic cloth ring 308 is pulled, and under the action of the synchronously descending pressure block 405, the elastic ring 307 on the top is separated from the feeding tube 8, and the elastic ring 307 quickly contracts, so that the elastic cloth ring 308 is stretched on the top of the feeding tube 406, and under the downward push of the pressure block 306, the elastic ring 307 on the top of the upper elastic cloth ring 308 remains on the feeding tube 8, and the elastic ring 307 at the bottom is separated from the feeding tube 8, so that the elastic cloth ring 308 is stretched on the bottom end of the feeding tube 8, and the fruit and vegetable powder remaining in the crusher 2 is shielded, thereby avoiding the waste of fruit and vegetable powder during the feeding process, avoiding the contamination of fruit and vegetable powder by impurities in the air, and at the same time, by suppressing the dust of fruit and vegetable powder, reducing the powder content in the air, optimizing the air quality, and improving the working environment.
