Description

Technical Field

[0001] The utility model relates to the technical field of granite sand-making transmission, in particular to a transmission structure for granite sand-making. Background Technique

[0002] Sand making mainly refers to processing mountain stones and river pebbles dug from river channels through an impact crusher (also known as a sand making machine) into sands suitable for construction. Sand making is widely used in various industries such as various ores, cement, refractory materials, bauxite clinker, emery, glass raw materials, machine-made building sand, stone materials, and various metallurgical slag.

[0003] During the sand-making process, the raw materials fall from the silo onto the vibrating feeder. After simple screening of the size specifications, they are evenly and continuously fed into the jaw crusher for crushing, and then sent to the cone crusher for further crushing until they are processed into particles of a fixed size and discharged. They are transported by a conveyor to the sand making machine, and then discharged after sufficient and effective crushing and transported to the classifier. The qualified finished products will be transported to the transfer pile, and those exceeding the screen specifications will be returned for sand making again.

[0004] There are many raw materials for sand making. As one of them, granite has a granular structure of fine grains, medium grains, or coarse grains, or a porphyritic-like structure. Its particles are uniform and fine, with small gaps, low water absorption rate, high hardness, and very good frost resistance. Granite often occurs in the form of batholiths, stocks, and rock blocks, and is controlled by regional tectonics.

[0005] During the process of using granite for sand making, a conveyor is required for corresponding conveying work, which can reduce labor and material resources and improve the sand-making efficiency. However, in the actual application process, due to the characteristics of high hardness and high density of granite itself, the degree of wear on the conveyor belt is high. During the conveying process, in addition to horizontal transmission, the raw materials also need to be lifted for transmission. After the conveyor belt is worn, it is not easy to maintain. Content of the Utility Model

[0006] In order to overcome the deficiencies that the conveyor used in the existing granite sand making process has a high degree of wear on the conveyor belt due to the hard and dense characteristics of granite itself, and during the conveying process, in addition to being transported horizontally, the raw materials also need to be lifted and transported. After the conveyor belt on the conveyor is worn, it is not easy to maintain. The embodiment of the present application provides a transmission structure for granite sand making. By controlling a transmission bracket at one end to move from the bottom to the top through a multi-stage hydraulic push rod, when the other transmission bracket rotates around the top of the fixed base A, multiple transmission brackets are simultaneously switched from a horizontal state to an inclined state, which can ensure that the linear distance of the vertical projection of both ends of the conveyor belt on the ground remains unchanged. And two adjacent transmission brackets drive the buckle seat to slide outside the sliding rod, making the overall length of the conveyor belt longer. After the conveyor belt is used for a period of time and worn, it can be released from a high place to the bottom without being affected by the positions of the equipment installed at both ends of the conveyor belt, which is conducive to maintenance and replacement.

[0007] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0008] A transmission structure for granite sand making, including transmission brackets, a conveyor belt and a sliding support structure. There are multiple transmission brackets, which are arranged in a row;

[0009] The conveyor belt circulates and rolls outside multiple transmission brackets;

[0010] There are multiple sliding support structures, which are respectively located between the two sides of adjacent transmission brackets;

[0011] Among them, the bottom of one end of the multiple transmission brackets in the combined state is hinged to the fixed base A, and the bottom of the other end of the multiple transmission brackets in the combined state is provided with multiple lifting support structures;

[0012] The multiple lifting support structures are combined in pairs and are respectively located on both sides of the bottom of the transmission brackets. The bottom of the two combined lifting support structures is provided with the same fixed base B. The inner wall of the bottom of the fixed base B is hinged with a multi-stage hydraulic push rod. The multi-stage hydraulic push rod controls one end of the multiple transmission brackets in the combined state to rotate around one end of the fixed base A, and the multiple transmission brackets approach and move away from each other through the sliding support structure.

[0013] In a possible implementation manner, the sliding support structure includes two buckle seats. The inner parts of both ends of the two buckle seats are slidably connected with sliding rods, and both ends of the sliding rods are respectively slidably connected inside adjacent transmission brackets.

[0014] In a possible implementation manner, the inner walls of the top and bottom of one side of the two buckle seats are welded and connected with guide sleeves, and both ends of the two sliding rods are respectively slidably connected inside the guide sleeves on the two buckle seats.

[0015] In a possible implementation, nuts are threadedly connected to the outsides of both ends of the sliding rod, and the diameters of the threaded portions machined at both ends of the sliding rod are smaller than the diameter at the center of the sliding rod. The two nuts are respectively located at one ends of the guiding sleeves on the two buckle seats.

[0016] In a possible implementation, the two buckle seats on one sliding support structure are respectively buckled to the outside of a corner of two adjacent transmission brackets and are fixed by bolt assembly, and a plurality of the sliding support structures are arranged in parallel.

[0017] In a possible implementation, two seat plates are arranged at the top of the lifting support structure, and the same support rod is pin-connected and fixed inside the two seat plates. A support seat is sleeved in the middle of the support rod, and one end of the multi-stage hydraulic push rod is hingedly connected to one end of the support seat.

[0018] In a possible implementation, one ends of two combined lifting support structures are respectively hinged to one ends of two seat plates, and the other ends of the two lifting support structures are respectively hinged to both sides of the top of the fixed base B.

[0019] In a possible implementation, the lifting support structure includes a plurality of connecting arms A and a plurality of support arms A. The plurality of connecting arms A are parallel to each other, the plurality of support arms A are parallel to each other, the plurality of connecting arms A and the plurality of support arms A correspond one by one, and are hinged to each other at the center and are in a crossed state. Both ends of one connecting arm A are respectively hingedly connected to one ends of two adjacent support arms A. One ends of the support arms A and support arms B located at both ends of the lifting support structure are respectively hinged to a connecting arm A and a connecting arm B, and one ends of the connecting arm A and the connecting arm B at the same height are hinged to each other.

[0020] The beneficial effects of this application are as follows:

[0021] First, in this solution, when a transmission bracket at one end is controlled by a multi-stage hydraulic push rod to move from the bottom to the top, and a transmission bracket at the other end rotates around the top of the fixed base A, multiple transmission brackets can be simultaneously switched from a horizontal state to an inclined state, which can ensure that the straight-line distance of the vertical projection of both ends of the conveyor belt on the ground remains unchanged. The adjacent two transmission brackets drive the buckle seats to slide on the outside of the sliding rod, so that the overall length of the conveyor belt becomes longer. After the conveyor belt is used for a period of time and worn, it can be released from a high place to a low place, and it will not be affected by the installation positions of the equipment at both ends of the conveyor belt, which is beneficial to maintenance and replacement.

[0022] Second, in this solution, when a transmission bracket is pushed by a multi-stage hydraulic push rod to switch from a horizontal state to an inclined state, the lifting support structure can be stretched in the vertical direction to ensure that the connection points between the seat plate and the transmission bracket are located at the same position in the horizontal projection plane, so as to support the conveyor belt outside multiple transmission brackets to descend to the ground for replacement or repair. After reinstallation, it is reset to the inclined state to carry out the conveying work of granite chips. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0029] Embodiment 1:

[0030] This embodiment introduces the specific structure of a transmission structure for granite sand making. Specifically, refer to Figures 1 - 4 as shown, including a plurality of transmission brackets 4 arranged in a row, a conveyor belt 5 circulating and rolling outside the plurality of transmission brackets 4, and a plurality of sliding support structures respectively located between the two sides of adjacent two transmission brackets 4. The sliding support structure includes two buckle seats 7, and sliding rods 8 are slidably connected to the inside of both ends of the two buckle seats 7;

[0031] Among them, multiple transmission brackets 4 are used in combination with multiple sliding support structures (forming a conventional conveyor belt). One end of the bottom of the multiple transmission brackets 4 in the combined state is hinged to a fixed base A1, and a plurality of lifting support structures 13 are provided at the bottom of the other end of the multiple transmission brackets 4 in the combined state. By slidingly connecting the two ends of the sliding rod 8 to the inside of two adjacent transmission brackets 4 respectively, when the multiple transmission brackets 4 change from a horizontal state to an inclined state, they can move away from each other, ensuring that the straight-line distance of the vertical projection of both ends of the conveyor belt onto the ground remains unchanged, while the overall length of the conveyor belt becomes longer;

[0032] Meanwhile, by respectively buckling the two buckle seats 7 on one sliding support structure to the outside of one corner of two adjacent transmission brackets 4, after fixing the buckle seats 7 and the transmission brackets 4 with bolts, they can be fixed by bolt assembly, enabling the multiple sliding support structures to be arranged in parallel, which is beneficial to ensuring the movement of the multiple transmission brackets 4 supported by the multiple sliding support structures;

[0033] Secondly, in order to enable the multiple transmission brackets 4 to switch between a horizontal state and an inclined state, as Figure 1 and Figure 4 shown, by arranging the multiple lifting support structures 13 in pairs and respectively on both sides of the bottom of the transmission brackets 4, a same fixed base B3 is provided at the bottom of the two combined lifting support structures 13. A multi-stage hydraulic push rod 12 is hinged to the inner wall of the bottom of the fixed base B3. When the multi-stage hydraulic push rod 12 controls one end of the multiple transmission brackets 4 in the combined state to rotate around one end of the fixed base A1, the multiple transmission brackets 4 can approach and move away from each other through the sliding support structures, which is simple and convenient;

[0034] Secondly, in order to ensure the stability of the sliding rod 8 moving between the two buckle seats 7, as Figure 2 and Figure 3 shown, guide sleeves 6 are welded to the top and bottom inner walls on one side of the two buckle seats 7. By slidingly connecting the two ends of the two sliding rods 8 to the inside of the guide sleeves 6 on the two buckle seats 7 respectively, a track is provided for the relative movement of the sliding rod 8 and the buckle seats 7, which can ensure the stable sliding of the sliding rod 8 between the two buckle seats 7;

[0035] Furthermore, in order to prevent the sliding rod 8 from detaching from the inside of the two buckle seats 7, as Figure 3 shown, nuts 9 are threadedly connected to the outside of both ends of the sliding rod 8. By making the diameter of the threaded part at both ends of the sliding rod 8 smaller than the diameter of the center of the sliding rod 8 and making the two nuts 9 respectively located at one end of the guide sleeves 6 on the two buckle seats 7, the two nuts 9 can be used to support at one end of the guide sleeves 6 on the two buckle seats 7 to control the maximum distance between two adjacent transmission brackets 4 moving away from each other.

[0036] By adopting the above technical solutions:

[0037] In the above design, the erection brackets of the traditional conveyor belt are set as a plurality of transmission brackets 4 arranged in a line, and a sliding support structure (mainly composed of two buckle seats 7 and two sliding rods 8) is arranged between the two sides of adjacent transmission brackets 4. When the multi-stage hydraulic push rod 12 controls one transmission bracket 4 at one end to move from the bottom to the top, causing one transmission bracket 4 at the other end to rotate around the top of the fixed base A1, multiple transmission brackets 4 can be simultaneously switched from a horizontal state to an inclined state. By setting the bottom of the multi-stage hydraulic push rod 12 at a fixed position, and the bottom of the transmission bracket 4 at this position is supported by two lifting support structures 13, it can be ensured that the straight-line distance of the vertical projections of both ends of the conveyor belt on the ground remains unchanged. The adjacent two transmission brackets 4 drive the buckle seats 7 to slide outside the sliding rods 8, increasing the overall length of the conveyor belt. This makes it convenient for the conveyor belt 5 to be released from a high place to a low place after being used for a period of time and worn, without being affected by the installation positions of the equipment at both ends of the conveyor belt.

[0038] It should be noted that, in order to ensure the overall structural strength of the conveyor belt in an inclined state, the lifting support structure 13 and the multi-stage hydraulic push rod 12 can be arranged at the bottom of one transmission bracket 4 on one side of adjacent transmission brackets 4 (the lifting support structure 13 and the multi-stage hydraulic push rod 12 cannot be arranged at the bottom of the transmission bracket 4 that is only hinged to the fixed base A1), which is beneficial to ensuring the structural strength according to actual application requirements.

[0039] Embodiment 2:

[0040] Based on Embodiment 1, this embodiment introduces the specific structure of the lifting support structure 13. Two seat plates 2 are arranged at the top of the lifting support structure 13, and the same support rod 10 is fixedly connected by pin joints inside the two seat plates 2. A support seat 11 is sleeved in the middle of the support rod 10;

[0041] Among them, by hingedly connecting one end of the multi-stage hydraulic push rod 12 to one end of the support seat 11, when the multi-stage hydraulic push rod 12 controls the multiple transmission brackets 4 to cooperate with the conveyor belt 5 (only listing relevant structures, structures such as rollers and motors are not relevant to this application and will not be elaborated) to form an inclined conveyor belt, it can be ensured that both ends of the multi-stage hydraulic push rod 12 automatically adapt to this motion state;

[0042] As Figure 4 shown, the lifting support structure 13 includes a plurality of connecting arms A133 and a plurality of support arms A131. One end of the support arms A131 and support arms B132 at both ends of the lifting support structure 13 are respectively hinged to the connecting arms A133 and connecting arms B134. The plurality of connecting arms A133 are parallel to each other, the plurality of support arms A131 are parallel to each other, the plurality of connecting arms A133 and the plurality of support arms A131 correspond one by one, and are hinged to each other at the center and are in a crossed state;

[0043] Among them, by respectively hinging the two ends of a connecting arm A133 to one ends of two adjacent supporting arms A131, one ends of the connecting arm A133 and the connecting arm B134 at the same height are hinged and combined with each other. One ends of the two lifting and supporting structures 13 are respectively hinged to one ends of two seat plates 2, and the other ends of the two lifting and supporting structures 13 are respectively hinged to both sides at the top of the fixed base B3, which can ensure the function that both ends of the lifting and supporting structure 13 can be longitudinally stretched (based on the characteristics of the easy deformation of the parallelogram).

[0044] By adopting the above technical solution:

[0045] In the above design, the longitudinally stretchable lifting and supporting structures 13 are arranged on both sides at the bottom of the transmission bracket 4, and a multi-stage hydraulic push rod 12 is arranged in a supporting manner between the two lifting and supporting structures 13. When the multi-stage hydraulic push rod 12 pushes a transmission bracket 4 to switch from a horizontal state to an inclined state, the lifting and supporting structure 13 can be stretched in the vertical direction, ensuring that the connection points between the seat plate 2 and the transmission bracket 4 are located at the same position in the horizontal projection plane and only move to different heights according to the state of the transmission bracket 4.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
