The lifting and conveying device is used for lifting materials to a high position, machining is facilitated, the buffering mechanism which keeps moving is arranged in the feeding mechanism so that the materials can be buffered when falling onto the climbing type conveying belt, and the situation that the climbing type conveying belt is damaged due to the fact that the materials are large and heavy and directly fall onto the climbing type conveying belt is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a lifting and conveying device. Background Art

[0002] During the processing of Chinese medicinal materials, the medicinal materials that are packaged for easy transportation need to be disassembled and transported to processing equipment, such as medicine cutting machines, screening machines, etc. During the transportation process, due to the high height of the processing equipment, when the staff transports the transported and disassembled medicinal materials to the processing equipment, they need to lift them to a high place and then dump them into the processing equipment, which requires a lot of physical strength and is inconvenient for the staff to operate.

[0003] For the above reasons, it is necessary to use a lifting device to lift and transport the medicinal materials. At present, the lifting devices generally include climbing conveyor belts, bucket elevators and screw conveyors. Screw conveyors are only suitable for the transportation of granular materials and are not convenient for transporting medicinal raw materials. The materials transported by bucket elevators are limited to small pieces of materials and are not convenient for the lifting and transportation of large pieces of materials. Therefore, climbing conveyor belts can only be used for the lifting and transportation of medicinal raw materials.

[0004] The climbing conveyor belt transports the material upwards by means of a tensioning belt stretched on an inclined frame. The medicinal raw materials are large blocks before cutting and are heavy. If workers dump them directly onto the tensioning belt, the sudden large gravity may cause the tensioning belt of the climbing conveyor belt to loosen, thereby affecting the transmission and causing increased wear on the transmission mechanism. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a lifting and conveying device, which facilitates the lifting and conveying of medicinal raw materials by setting a climbing conveyor belt. At the same time, by setting a buffer mechanism that is movable in the feeding mechanism, the medicinal raw materials can be buffered to prevent the medicinal raw materials from falling directly onto the conveyor belt, causing the conveyor belt to loosen or aggravate wear, affecting the feeding and extending the service life.

[0006] The utility model is implemented as follows: a lifting and conveying device is constructed, including a climbing conveyor belt, a feeding mechanism is provided at the feeding end of the climbing conveyor belt, and a buffer mechanism is movably provided inside the feeding mechanism. When small pieces of material are being fed, the small pieces of material slide from the gap between the feeding mechanism and the buffer mechanism to the climbing conveyor belt for transportation. When large pieces of material are being fed, the large pieces of material push the buffer mechanism to rotate toward one side of the inner end of the feeding mechanism during the sliding process, so as to expand the gap between the buffer mechanism and the feeding mechanism and keep the large pieces of material passing through the gap and falling onto the climbing conveyor belt.

[0007] Specifically, the climbing conveyor belt includes an inclined conveyor belt body and a frame for supporting the conveyor belt body and maintaining transmission. The feeding mechanism is arranged at the top of the lower end of the conveyor belt body, and a discharge pipe is arranged at the bottom of the upper end of the conveyor belt body.

[0008] Specifically, the feeding mechanism includes a conical hopper and a supporting column. The conical hopper is horizontally arranged above the conveyor belt and fixed to the frame through the supporting column. The buffer mechanism is arranged in the conical hopper.

[0009] Specifically, the buffer mechanism includes two support rods, which are arranged opposite to each other at the center of the inner end of the conical hopper and kept horizontal;

[0010] Two insertion rods movably connected to the ends of the two support rods;

[0011] The buffer block is sleeved on the outer ends of the two insertion blocks.

[0012] Specifically, one end of the support rod is fixed on the inner end of the conical hopper, and the other end is provided with a spiral portion that is movably connected to the insertion rod. One end of the two insertion rods is threadedly connected to the support rod, and the other end is sleeved on the outer end of the intermediate rod to maintain linear sliding and rotation. A threaded hole is opened at the end of the intermediate rod. After the insertion rod is sleeved on the outer end of the intermediate rod, it is screwed into the threaded hole of the intermediate rod through a fastener to achieve positioning.

[0013] Specifically, the buffer block is in the shape of a triangular block, with a through hole penetrating through the end portion, and is sleeved on the outer end of the insertion rod through the through hole at the end portion, and chamfered corners are provided on the ridges of the inner and outer ends of the buffer block.

[0014] Specifically, a baffle is installed on the through hole at the end of the buffer block, and a through hole for inserting the rod is opened at the center of the baffle.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] The lifting and conveying device is convenient for lifting and conveying medicinal raw materials by providing a climbing conveyor belt, thereby facilitating the conveying of the medicinal raw materials to the processing equipment for processing. At the same time, by providing a feeding mechanism on the climbing conveyor belt and an internal movable buffer mechanism, it can prevent the medicinal raw materials from directly falling onto the conveyor belt during the feeding process, causing increased wear of the transmission mechanism of the climbing conveyor belt or loosening of the conveyor belt, thereby ensuring the lifting and conveying of the medicinal raw materials and also ensuring the service life of the entire device.

[0027] The technical solution of the present invention will be further described in detail below through specific embodiments and in combination with the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention in any way. The accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding and are not intended to limit the present invention in any way.

[0028] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions for the implementation of the present invention. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0029] As described in the background technology, most of the current lifting and conveying devices are not convenient for lifting and conveying medicinal raw materials. When a climbing conveyor belt is used to convey medicinal raw materials, if the medicinal raw materials are directly poured onto the conveyor belt, the gravity of the medicinal materials will cause the transmission mechanism of the climbing conveyor belt to wear more severely, and may also cause the conveyor belt to loosen.

[0030] For the reasons mentioned above, please refer to the attached Figure 1 ~Attached Figure 3 The utility model provides a lifting and conveying device, including a climbing conveyor belt 1, a feeding mechanism 2 is provided at the feeding end of the climbing conveyor belt 1, and a buffer mechanism 3 is movably provided inside the feeding mechanism 2. When small pieces of material are being fed, the small pieces of material slide from the gap between the feeding mechanism 2 and the buffer mechanism 3 to the climbing conveyor belt 1 for transportation. When large pieces of material are being fed, the large pieces of material push the buffer mechanism 3 to rotate toward the inner end of the feeding mechanism 2 during the sliding process, so as to expand the gap between the buffer mechanism 3 and the feeding mechanism 2 and keep the large pieces of material passing through the gap and falling onto the climbing conveyor belt 1.

[0031] Specifically, the climbing conveyor belt 1 includes an inclined conveyor belt body and a frame for supporting the conveyor belt body and maintaining transmission. The feeding mechanism 2 is arranged at the top of the lower end of the conveyor belt body, and a discharge pipe 4 is arranged at the bottom of the upper end of the conveyor belt body.

[0032] Please see the attached Figure 4 Specifically, the feeding mechanism 2 includes a conical hopper 201 and a support column 202. The conical hopper 201 is horizontally arranged above the conveyor belt body and is fixed to the frame through the support column 202. The buffer mechanism 3 is arranged in the conical hopper 201.

[0033] The conical hopper can achieve initial buffering when the medicinal raw materials are unloaded, and at the same time facilitate the medicinal raw materials to fall onto the belt surface of the climbing conveyor belt.

[0034] Please see the attached Figure 4 and attached Figure 5 Specifically, the buffer mechanism 3 includes two support rods 301, which are arranged oppositely at the center of the inner end of the conical hopper 201 and kept horizontal;

[0035] Two insertion rods 302 are movably connected to the ends of the two support rods 301;

[0036] The buffer block 303 is sleeved on the outer ends of the two insertion blocks 302 .

[0037] Please combine the attached Figure 6 and attached Figure 7 Specifically, one end of the support rod 301 is fixed on the inner end of the conical hopper 201, and the other end is provided with a spiral portion that maintains a movably connected with the insertion rod 302. One end of the two insertion rods 302 is threadedly connected to the support rod 301, and the other end is sleeved on the outer end of the intermediate rod 304 to maintain linear sliding and rotation. A threaded hole is opened at the end of the intermediate rod 304. After the insertion rod 302 is sleeved on the outer end of the intermediate rod 304, it is screwed into the threaded hole of the intermediate rod 304 through the fastener 305 to achieve positioning.

[0038] By setting the spiral portion on the support rod, the intermediate rod and the insertion rod, it is convenient to install the buffer block in the conical hopper 201 for buffering. The fastener is set to prevent the intermediate rod from being inserted into the inner end of any insertion rod, affecting the connection between the two insertion rods.

[0039] Please refer to the attached Figure 5 Specifically, the buffer block 303 is in the shape of a triangular block, with a through hole opened at the end, and is sleeved on the outer end of the insertion rod 302 through the through hole at the end, and chamfered corners are provided on the edges of the inner and outer ends of the buffer block 303.

[0040] The buffer block is set in the shape of a triangular block and has an internal through hole so that it can be easily mounted on the outside of the insertion rod to block the medicinal raw materials, thereby achieving the purpose of buffering. When the medicinal raw materials are in the shape of small pieces (usually small pieces of medicinal materials are lighter in weight), the medicinal raw materials can pass through the gap between the triangular block and the conical hopper and fall onto the conveyor belt below. When the medicinal raw materials are in the shape of large pieces (usually large pieces of medicinal materials are heavier), the large pieces of material cannot pass through the gap between the triangular block and the conical hopper, so they will push the triangular block to rotate around the insertion rod. During the pushing and rotating process, the weight of the triangular block itself needs to be overcome, thereby achieving buffering when the large pieces of material fall.

[0041] Please see the attached Figure 8 Specifically, a baffle 5 is installed on the through hole at the end of the buffer block 303, and a through hole for inserting the rod 302 is opened at the center of the baffle 5.

[0042] The purpose of providing the baffle is to prevent the medicinal material raw materials from falling into the through hole of the buffer block and affecting the feeding of the medicinal material raw materials.

[0043] Before using the lifting and conveying device, the buffer mechanism is pre-installed. During installation, first, the two insertion rods 302 are put on the outside of the middle rod 304 and limited by the fasteners 305, and then the buffer block 303 is put on the outside of the insertion rod 302, and the baffle 5 is fixed to the end of the buffer block 303 (it can be connected by welding or bolts and nuts, which is a conventional connection method and will not be described in detail here), and finally, the end of the insertion rod 302 is put on the spiral part of the support rod 301 and kept screwed and fixed.

[0044] During use, the driving motor of the climbing conveyor belt 1 is started in advance to drive the conveyor belt for transmission, and then the staff pours the medicinal raw materials into the conical hopper 201. The medicinal raw materials pass through the gap between the buffer block 303 and the inner wall of the conical hopper 201 in turn and fall onto the climbing conveyor belt 1, realizing material dropping and buffering. The large pieces of material will push the buffer block 303 to rotate around the insertion rod 302 (if gravity cannot push it, it needs to be pushed manually), so that the gap between the buffer block 303 and the inner wall of the conical hopper 201 is expanded, and the large pieces of material pass through the expanded gap and fall onto the climbing conveyor belt 1, realizing material dropping and buffering. Finally, under the drive of the climbing conveyor belt 1, the medicinal raw materials are transported upward and discharged into the external processing equipment from the discharge pipe 4 at the top, realizing the lifting and transportation of the medicinal raw materials.

[0045] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
