Description

Technical Field

[0001] The invention relates to stone cutting equipment, in particular to a stone cutting conveying line. Background Art

[0002] Stone cutting equipment is a type of stone cutting machinery, which is used to cut stone into strips of required size horizontally and vertically. Traditional stone cutting uses a single knife, which is extremely inefficient. Currently, single knives are generally replaced with multiple knives, which improves efficiency, but there are still major shortcomings.

[0003] At present, there are two main methods for cutting stone strips. One is to cut horizontally and vertically separately, which requires multiple loading and unloading operations, which is cumbersome and inefficient. The other is to cut vertically and vertically in one flow, first cutting vertically into several intermediate plates, then conveying, turning, flipping, and connecting the intermediate plates one by one, and then cutting vertically. Although it saves the operation of loading and unloading in the middle, the series of operations in the middle to achieve the turning cutting not only greatly lengthens the entire cutting production line, but also complicates the operation, and requires high matching accuracy. The production efficiency is still not ideal, which affects the production benefits.

[0004] In view of this, this case conducts an in-depth study on the above-mentioned problems, innovatively proposes a stone cutting device, and accordingly proposes a stone cutting conveyor line. Summary of the invention

[0005] The purpose of the present invention is to provide a stone cutting conveyor line, which cleverly designs a coupling transfer conveyor and a conveyor vehicle to achieve independent but linked transmission of the first and second conveyor lines. The production line is greatly shortened compared with the prior art and the production efficiency is greatly improved.

[0006] In order to achieve the above object, the solution of the present invention is:

[0007] A stone cutting conveyor line comprises a first conveyor line, a second conveyor line, and a coupling transfer bearing conveyor with a transfer bearing connected between the first conveyor line and the second conveyor line; the first conveyor line and the second conveyor line respectively have a first conveying vehicle and a second conveying vehicle which convey back and forth on the conveyor line; the first conveying vehicle is provided with a first vehicle-mounted roller group and a first vehicle-mounted transmission assembly, and the second conveying vehicle is provided with a second vehicle-mounted roller group and a second vehicle-mounted transmission assembly; the coupling transfer bearing conveyor comprises a transfer bearing frame, a transfer bearing roller group and a transfer bearing transmission assembly; the transfer bearing roller group, the first vehicle-mounted roller group and the second vehicle-mounted roller group are all arranged for conveying along the direction where the transfer bearing is located; the transfer bearing roller group is driven by the transfer bearing transmission assembly, and a coupling assembly is provided between the transfer bearing transmission assembly and the first vehicle-mounted transmission assembly, and between the transfer bearing transmission assembly and the second vehicle-mounted transmission assembly.

[0008] The first conveying line and the second conveying line are coaxially conveyed or perpendicularly conveyed.

[0009] The first conveying line and the second conveying line are coaxially conveyed. The first conveying line has a material feeding position, a cutting position and a material discharging position along the conveying direction; the second conveying line has a material receiving position, a cutting position and a material discharging position along the conveying direction.

[0010] The first conveyor line and the second conveyor line are axially conveyed at right angles to each other. The first conveyor line has a material input position, a cutting position and a material output position along the conveying direction; the second conveyor line has a material receiving / output position and a cutting position along the conveying direction, or the second conveyor line has a material receiving position, a cutting position and a material output position along the conveying direction.

[0011] The stone material turning conveyor further comprises a coupling discharging machine, which is arranged beside the receiving / discharging position of the second conveying line.

[0012] The first conveyor vehicle and the second conveyor vehicle both include an upper frame and a lower frame; a slat group is provided on the lower frame, and a traveling wheel group is provided at the bottom of the lower frame; the upper frame is movably mounted on the lower frame, and a supporting wheel group is provided at the bottom of the upper frame, and the supporting wheel group is arranged in parallel with the wheel running direction of the traveling wheel group; the upper frame is provided with a vehicle-mounted roller group which is staggered one by one with the slat group of the lower frame; a supporting inclined surface group is provided near the end where the coupling transfer conveyor is located on the first conveyor line and the second conveyor line, and the supporting wheel group has a high and low supporting state through the cooperation of the supporting inclined surface group, so that the vehicle-mounted roller group can be lifted or lowered above or below the slat group accordingly.

[0013] The support wheel set is arranged at the bottom of the upper frame at a wheel line position corresponding to the wheel travel direction of the staggered traveling wheel set.

[0014] The first vehicle-mounted transmission assembly and the second vehicle-mounted transmission assembly both include a transmission main shaft and a plurality of bevel gear sets; the bevel gear sets include corresponding meshing transmission first and second bevel gears; the first bevel gears of the plurality of bevel gear sets are installed on the transmission main shaft at intervals, and the second bevel gears of the plurality of bevel gear sets are installed one by one on the roller shafts of the roller sets.

[0015] The lower vehicle frame is integrally provided with a bottom plate group consisting of a plurality of support bottom plates spaced and arranged side by side; the strip plate group consists of a plurality of wooden strip plates, and the plurality of wooden strip plates can be detachably fixed on the plurality of support bottom plates in a one-to-one correspondence.

[0016] The transfer bearing transmission assembly includes a transmission main shaft and a plurality of bevel gear sets; the bevel gear sets include first and second bevel gears that mesh with each other for transmission; the first bevel gears of the plurality of bevel gear sets are installed on the transmission main shaft at intervals, and the second bevel gears of the plurality of bevel gear sets are installed one by one on the roller shafts of the vehicle-mounted roller sets; the non-two end positions of the transmission main shaft are transmission-connected with a transfer bearing drive assembly, and the two end positions of the transmission main shaft are respectively connected to the coupling assembly.

[0017] There are two transmission main shafts, the inner ends of the two transmission main shafts are transmission-connected to the transfer bearing drive assembly through a transmission mechanism, and the outer ends of the two transmission main shafts are respectively connected to the coupling assembly.

[0018] The coupling-type transfer conveyor also includes a sorting component, which has two groups of tightening cylinder groups. The two groups of tightening cylinder groups are arranged above the transfer roller group and are relatively arranged perpendicular to the conveying direction of the rollers.

[0019] The first conveying vehicle is connected to a first driving assembly, and the second conveying vehicle is connected to a second driving assembly; the first driving assembly and the second driving assembly both include a driving motor, two transmission wheel groups and a transmission belt; the driving motor is connected to a transmission wheel group in a transmission manner, the two transmission wheel groups are arranged front and back along the conveying direction, the transmission belt is wound around the two transmission wheel groups, and the bottom of the first conveying vehicle or the second conveying vehicle is connected to the transmission belt.

[0020] After adopting the above scheme, the stone cutting conveyor line of the present invention has the following beneficial effects compared with the prior art: the first and second conveyor lines are designed, and the transition is made through the coupling transfer conveyor in the middle, so that two sets of conveyor lines that are both independent and connected by coupling transmission are obtained. The stone to be cut can be fed from the first conveyor line or the second conveyor line, and is fed out after being cut once on the first conveyor line and the second conveyor line respectively.

[0021] The first conveyor line and the second conveyor line can be coaxially conveyed, which is particularly suitable for 90-degree steering conveying, and the conveying advantage is very significant. Stone cutting usually requires horizontal and vertical cutting to obtain the required specific size. The horizontal and vertical cutting involves the stone turning operation. For example, after the stone to be cut is cut in a specific direction (such as horizontal) on the first conveyor line, the first conveyor vehicle carries the cut stone slab group and conveys it to the coupling transmission with the coupling transfer conveyor, and the stone slab group is conveyed to the transfer roller group; then the first conveyor vehicle returns and repeats the above operation with high efficiency; the second conveyor vehicle is coupled with the coupling transfer conveyor (the coupling transmission operation timing can be synchronized with the aforementioned first conveying coupling transmission operation or performed later), and the stone slab group received by the transfer roller group is transferred to the second conveyor vehicle, and the second conveyor vehicle carries the stone slab group for longitudinal movement to realize the specific turning (such as longitudinal) of the stone slab group and cuts it into a stone bar group of specific required size; then the second conveyor vehicle sends the stone bar group out and repeats the above operation with high efficiency.

[0022] The stone cutting conveyor line in this case uses the clever coordination of the coupling transfer conveyor and the conveyor vehicle to achieve independent and linked transmission of the first and second conveyor lines. They can be operated synchronously during work, which is simple to operate and does not affect each other. It is particularly suitable for stone steering conveying, without the need for complicated rotation, flipping and other operations. Through linkage and combined drive, the front and rear conveying can not only be seamlessly connected, but also without the need to accurately control the transmission time coordination of each conveying section. The cutting operation control is very simple and reliable. The production line is greatly shortened compared to the existing technology, and the production efficiency is greatly improved. The use of the conveyor vehicle form can achieve simple transportation while also being very conducive to coordination with the coupling transfer, and can also flexibly coordinate with the cutting part, flexibly changing the design of the cutting operation position, thereby greatly simplifying the entire production line and achieving high-efficiency production.

[0047] The case is further described in detail below in conjunction with specific implementation methods.

[0048] This case involves a stone cutting conveyor line, such as Figure 1-9 As shown, it includes a first conveyor line 100, a second conveyor line 400, and a coupling transfer conveyor 700 transfer-connected between the first conveyor line 100 and the second conveyor line 400.

[0049] The first conveyor line 100 is provided with a first conveyor vehicle 200, which conveys back and forth on the first conveyor line 100; the first conveyor vehicle 200 is provided with a first vehicle roller group 211 and a first vehicle transmission assembly 23 which are mutually transmission-connected. Similarly, the second conveyor line 400 is provided with a second conveyor vehicle 500, which conveys back and forth on the second conveyor line 400; the second conveyor vehicle 500 is provided with a second vehicle roller group 511 and a second vehicle transmission assembly 53 which are mutually transmission-connected.

[0050] The coupling type transfer conveyor 700 includes a transfer frame 71, a transfer roller group 72 and a transfer transmission assembly 73; the transfer roller group 72 is installed on the transfer frame 71, and is driven by the transfer transmission assembly 73 for rolling conveying, and the rolling conveying direction is the transfer direction of the conveyor line. The transfer roller group 72, the first vehicle-mounted roller group 211 and the second vehicle-mounted roller group 511 are all arranged for rolling conveying along the direction where the transfer is located. A coupling assembly 74 is provided between the transfer transmission assembly 73 and the first vehicle-mounted transmission assembly 23, and between the transfer transmission assembly 73 and the second vehicle-mounted transmission assembly 53.

[0051] Thus, the vehicle-mounted transmission assembly 23 and the transfer bearing transmission assembly 73 can be separated from each other or combined with each other by means of the corresponding coupling assembly 74; similarly, the vehicle-mounted transmission assembly 53 and the transfer bearing transmission assembly 73 can be separated from each other or combined with each other by means of the corresponding coupling assembly 74. The coupling assembly 74 can be made of an existing related coupling device, and the coupling assembly 74 is divided into a first coupling part 741 and a second coupling part 742, which are respectively installed on the relevant transmission shafts of the vehicle-mounted transmission assembly 23 and the transfer bearing transmission assembly 73, and on the relevant transmission shafts of the vehicle-mounted transmission assembly 53 and the transfer bearing transmission assembly 73. The first conveying vehicle 200 and the second conveying vehicle 500 do not have the power to automatically transmit the stone slab group by themselves, and the power is provided by the coupling transfer bearing conveyor 700, that is, it relies on the combination and linkage with the coupling transfer bearing conveyor 700.

[0052] The conveying directions of the first conveying line 100 and the second conveying line 400 can be coaxial conveying or perpendicular axial conveying. The specific implementation method given adopts perpendicular axial conveying.

[0053] When the first conveyor line 100 and the second conveyor line 400 are coaxially conveyed, the first conveyor line 100 has a material input position, a cutting position and a material output position along the conveying direction; the second conveyor line 400 has a material receiving position, a cutting position and a material output position along the conveying direction. Thus, the stone to be cut is fed in from the first conveyor line 100, and after the first cutting, it is transferred to the second conveyor line 400 for the second cutting, and is directly sent out after the cutting is completed. The two cuttings can be designed with different saw blade cutting directions to achieve the purpose of horizontal and vertical cutting.

[0054] In the preferred embodiment, the first conveyor line 100 and the second conveyor line 400 are axially conveyed perpendicularly to each other. The first conveyor line 100 has a material input position, a cutting position, and a material output position along the conveying direction; the second conveyor line 400 has a material receiving / discharging position and a cutting position along the conveying direction, or the second conveyor line has a material receiving position, a cutting position, and a material output position along the conveying direction. For example, the first conveyor line 100 is horizontal and the second conveyor line 400 is vertical. The entire conveyor line realizes the high-efficiency horizontal and vertical flow-cutting operation of stone. Taking the first conveyor line 100 as the front end of the assembly line as an example (of course, the direction can also be reversed), the operation steps are:

[0055] 1) The stone to be cut is fed into the front receiving position of the first conveyor line 100. After the first conveyor vehicle 200 receives the stone to be cut at the receiving position, the first conveyor vehicle 200 is transported backward to the cutting position, and the stone to be cut on the first conveyor vehicle 200 is transversely cut into stone slabs by the relevant saw blade cutting assembly.

[0056] 2) Afterwards, the first conveyor vehicle 200 carries the transversely cut stone slab group and conveys it to the discharge position. With the help of the corresponding coupling assembly 74, the vehicle-mounted transmission assembly 23 of the first conveyor vehicle 200 and the transfer bearing transmission assembly 73 are automatically linked and combined;

[0057] 3) The transfer transmission assembly 73 starts working, driving the transfer roller group 72 to roll, and also drives the vehicle roller group 211 of the first conveyor 200 to roll synchronously, and the stone slab group is transported from the vehicle roller group 211 to the transfer roller group 72; then the first conveyor 200 disengages the linkage and returns, and repeats the above steps 1)-2) operations; that is, the continuous and efficient flow operation of horizontal cutting and conveying of stone is realized;

[0058] 4) The second conveyor 500, at the receiving position, uses the corresponding coupling assembly 74 to automatically link the vehicle transmission assembly 53 and the transfer bearing transmission assembly 73, and the transfer bearing transmission assembly 73 starts to work, driving the transfer bearing roller assembly 72 to roll, and also drives the vehicle roller assembly 511 of the second conveyor 500 to roll synchronously, and the stone slab group received by the transfer bearing roller assembly 72 is transferred to the vehicle roller assembly 511 of the second conveyor 500; the second conveyor 500 flexibly turns the stone slab group by 90 degrees (from horizontal to longitudinal direction);

[0059] It should be noted here that, in the preferred solution, steps 3) and 4) are operated independently of each other in the front and back steps, that is, the first conveyor vehicle 200 and the second conveyor vehicle 500 are linked with the coupling transfer conveyor 700 in turn. Such a design is conducive to the first conveyor vehicle 200 and the second conveyor vehicle 500 to perform their own independent conveying and cutting operations without affecting each other, without being restricted by each other and incurring waiting time, thereby improving efficiency.

[0060] Of course, step 3) and step 4) can also be performed simultaneously, that is, the vehicle-mounted transmission component 23 and the transfer bearing transmission component 73 are linked together, and the vehicle-mounted transmission component 53 and the transfer bearing transmission component 73 are also linked together, thereby, the vehicle-mounted roller group 211, the transfer bearing roller group 72 and the vehicle-mounted roller group 511 roll synchronously, and the slab group can be transferred to the vehicle-mounted roller group 511 in one step.

[0061] 5) The roller assembly 511 of the second conveyor 500 carries the stone slab assembly and moves longitudinally. After moving to the cutting position, the relevant saw blade cutting assembly cuts the stone slab assembly longitudinally into stone strips of specific required sizes. After that, the second conveyor 500 sends out the stone strips and repeats the above operation, that is, after the horizontal cutting of the stone is completed, the continuous longitudinal cutting and transportation are completed, achieving a continuous and efficient flow operation.

[0062] Furthermore, after the longitudinal cutting is completed, the second conveyor vehicle 500 sends out the stone bar group and then moves back and forth to repeat the operation. Here, the second conveyor vehicle 500 sends out the stone bar group, and the scheme adopted is the first one, corresponding to the "material receiving position-cutting position-discharging position" of the second conveying line 400. After the second conveyor vehicle 500 completes the longitudinal cutting, it continues to transport backward, and the cut stone bar group is taken out by the relevant material taking device, and then the second conveyor vehicle 500 returns to repeat the operation. The second one corresponds to the "material receiving / discharging position-cutting position" of the second conveying line 400. Considering that the second conveyor vehicle 500 needs to return to the front end receiving position, the delivery position of the stone bar group can be designed to correspond to the material receiving position. Further, a unified coupling conveying method can be adopted, which can shorten the time for the second conveyor vehicle 500 to operate back and forth once, thereby improving efficiency. Specifically, a coupling discharging machine is also connected to the front end of the second conveyor line 400, and the coupling discharging machine is located at the rear position of the second conveyor line 400 in the horizontal direction. A coupling assembly is provided between the coupling discharging machine and the vehicle-mounted transmission assembly 53 of the second conveyor vehicle 500. In this way, when the second conveyor vehicle 500 returns to repeat the operation of step 4), the vehicle-mounted transmission assembly 53 and the transfer bearing transmission assembly 73 are linked and combined, and the vehicle-mounted transmission assembly 53 is also linked and combined with the coupling discharging machine, and the stone slab group received by the transfer bearing roller group 72 is transferred to the vehicle-mounted roller group 511 of the second conveyor vehicle 500. At the same time, the stone strip group on the vehicle-mounted roller group 511 can be synchronously sent to the coupling discharging machine, so that the second conveyor vehicle 500 can simultaneously perform discharging and receiving operations, and the production efficiency is further improved.

[0063] Optimal solution: In order to facilitate the conveyor vehicle to cooperate with the cutting operation reliably and efficiently and avoid possible cutting damage (mainly referring to the roller group part), this case also proposes a preferred design solution for the first conveyor vehicle 200 and the second conveyor vehicle 300.

[0064] Preferred solution, taking the first transport vehicle 200 as an example

[0065] The first transport vehicle 200 includes an upper frame 21 and a lower frame 22 that are movably assembled with each other. The lower frame 22 is provided with a strip plate group 221, which is composed of a plurality of strip plates that are parallel to each other and spaced apart and arranged side by side. The bottom of the lower frame 22 is provided with a running wheel group 222, which serves as the running and transporting wheel of the first transport vehicle 200 and is mounted on the running rail 11 for running. The upper frame 21 is movably mounted on the lower frame 22. The upper frame 21 is provided with a vehicle-mounted roller group 211, which is composed of a plurality of rollers that are parallel to each other and spaced side by side. The plurality of rollers of the vehicle-mounted roller group 211 and the plurality of strips of the strip group 221 are staggered in the horizontal direction (preferably staggered one by one). In this way, when the height position of the upper frame 21 relative to the lower frame 22 is changed, the vehicle-mounted roller group 211 can be raised and lowered relative to the strip group 221, thereby realizing the relative height change adjustment of the two.

[0066] The scheme for changing the height position of the upper frame 21 relative to the lower frame 22 is that a support wheel group 212 is provided at the bottom of the upper frame 21, and the wheel travel direction of the support wheel group 212 and the running wheel group 222 are arranged in parallel, that is, the wheel axes of the support wheel group 212 and the running wheel group 222 are parallel to each other, so that during the movement and sliding of the running wheel group 222, the support wheel group 212 is also in a state of being able to slide. A support inclined surface group 12 is provided on the first conveyor line 100, near the end where the coupling transfer conveyor 700 is located. The purpose of the support inclined surface group 12 is to allow the support wheel group 212 to crawl on it, and to change the height of the support wheel group 212 by the slope of the inclined surface, so that the support wheel group 212 has a high and low support state, and finally realizes the vehicle-mounted roller group 211 to be higher or lower than the strip plate group 221. The adjustable lifting action.

[0067] Further, the purpose of the support inclined plane group 12 is to allow the support wheel group 212 to crawl on it, and the extending direction of the inclined plane of the support inclined plane group 12 is the wheel direction of the support wheel group 212 (the direction of the walking rail 11). In order to facilitate the support wheel group 212 to smoothly enter and exit the support inclined plane group 12, the corresponding matching surface of the support inclined plane group 12 and the matching surface of the support wheel group 212 are designed to be a first inclined plane, a second inclined plane and a high plane that are successively connected from low to high. The high plane is close to the side where the coupling transfer conveyor 700 is located, so that the first transport vehicle 200 can stay there steadily and perform the coupling and combination with the coupling transfer conveyor 700. The inclination of the first inclined plane is greater than the inclination of the second inclined plane. The crawling process of the support wheel group 212 is appropriately buffered by two inclined planes with different inclinations, thereby improving the stability and reliability of the overall transportation of the first transport vehicle 200.

[0068] Thus, in step 1) of the above operation steps, the first transport vehicle 200 receives the material at the front end, at which time the supporting wheel group 212 is in a naturally sinking state, the upper frame 21 is directly placed on the lower frame 22 and supported by it, at which time the vehicle-mounted roller group 211 is lower than the slat group 221, and the stone to be cut is supported by the slat group 221; the first transport vehicle 200 is transported to the cutting position for cutting, and during the cutting process, the stone is stably placed on the slat group 221 waiting to be cut, and the saw blade group correspondingly saws on the slat group 221, and the sinking vehicle-mounted roller group 211 can avoid the problem that the saw blade group may accidentally cut it. The slat group 221 preferably adopts wooden slats, that is, it is composed of a plurality of wooden slats, and the plurality of wooden slats can be disassembled and fixed on the lower frame 22 one by one. Preferably, the lower frame 22 is provided with a bottom plate group 223 which is arranged side by side by a plurality of support bottom plates at intervals, so as to facilitate the disassembly and fixation of the wooden slats one by one and the replacement operation.

[0069] Afterwards, in step 2) of the above-mentioned operation steps, the first conveyor 200 carries the transversely cut stone slab group and continues to convey it forward, and the supporting wheel group 212 correspondingly touches the supporting ramp group 12 and crawls on it. When it crawls to the set high position (the high plane position of the supporting ramp group 12), at this time, the vehicle-mounted roller group 211 rises to be higher than the strip group 221, and takes over the stone slab group on the strip group 221; and at this time, the first conveyor 200 is also in the discharge position, and the rising vehicle-mounted transmission assembly 23 is at the coupling combination position, with the help of the corresponding coupling assembly 74, the vehicle-mounted transmission assembly 23 and the transfer bearing transmission assembly 73 of the first conveyor 200 are automatically linked and combined; then step 3) can be carried out, the vehicle-mounted roller group 211 and the transfer bearing roller group 72 take over each other and synchronize the rollers to realize the conveying of the stone slab group.

[0070] In the preferred embodiment, the second transport vehicle 500 has the same structural design concept as the first transport vehicle 200. The second transport vehicle 500 includes an upper frame 51 and a lower frame 52. The upper frame 51 is provided with a vehicle roller group 511, and the lower frame 52 is provided with a strip plate group 521 and a running wheel group 522. The structural coordination of the above-mentioned parts is the same as the corresponding structural coordination of the first transport vehicle 200, and will not be described in detail here. The difference lies in the change in the horizontal and vertical directions. The running wheel group 522 is set on the running rail 41 for longitudinal running.

[0071] The scheme of changing the height position of the upper frame 51 relative to the lower frame 52 is similar to the first transport vehicle 200. The bottom of the upper frame 51 is provided with a support wheel group 512, and the wheel travel direction of the support wheel group 512 is arranged parallel to the wheel travel direction of the running wheel group 522. On the second conveyor line 400, near the end where the coupling type transfer conveyor 700 is located, a support inclined plane group 42 is arranged. Similarly, the purpose of the support inclined plane group 42 is to allow the support wheel group 512 to crawl on it, and to change the height of the support wheel group 512 by the slope of the inclined plane, and finally realize the lifting and lowering adjustable action of the vehicle-mounted roller group 511 higher or lower than the strip plate group 521. The support wheel group 512 is similarly provided with four groups, each group includes a support rod 5121 and a support wheel 5122, which will not be repeated here. Similarly, the support inclined plane group 42 is designed with a first inclined plane, a second inclined plane and a high plane that are successively undertaken from low to high, and the high plane is close to the side where the coupling type transfer conveyor 700 is located. For details, please refer to the similar description of the supporting inclined surface group 12 of the first transport vehicle 200.

[0072] Thus, in step 4) of the above-mentioned operation steps, the second transport vehicle 500 is at the front end of the second conveyor line 400 (i.e., close to the end where the coupling transfer conveyor 700 is located), at which time the supporting wheel group 512 is on the high plane of the supporting inclined plane group 42, and the vehicle-mounted roller group 511 is higher than the slat group 521; and the vehicle-mounted transmission assembly 53 of the second transport vehicle 500 is in an ascending state and is also in the position where the coupling is combined, and with the help of the corresponding coupling assembly 74, the vehicle-mounted transmission assembly 53 and the transfer transmission assembly 73 are automatically linked and combined, and the transfer transmission assembly 73 starts working, driving the transfer roller group 72 to roll, and also driving the vehicle-mounted roller group 511 of the second transport vehicle 500 to roll synchronously, and the slab group received by the transfer roller group 72 is transferred to the vehicle-mounted roller group 511 of the second transport vehicle 500;

[0073] Afterwards, in step 5) of the above-mentioned operation steps, the vehicle-mounted roller group 511 of the second transport vehicle 500 carries the stone slab group and moves backward in the longitudinal direction. During the backward movement, the supporting wheel group 512 correspondingly crawls downward along the supporting inclined surface group 42. When it descends and separates from the supporting inclined surface group 42, the supporting wheel group 512 is in a natural sinking state, and the upper frame 51 is directly placed on the lower frame 52 and supported by it. At this time, the vehicle-mounted roller group 511 is lower than the strip board group 521, and the stone slab group to be cut is supported by the strip board group 521 from the vehicle-mounted roller group 511; the second transport vehicle 500 continues to move backward to the cutting position to cut the stone slab group longitudinally.

[0074] The conveyor line of this case is designed with a first conveyor vehicle 200 and a second conveyor vehicle 500. When the two are combined in a perpendicular conveying direction, from a structural point of view, the difference between the two is mainly reflected in the different direction relationship between the running wheel group and the vehicle-mounted roller group. The running direction of the running wheel group 222 of the first conveyor vehicle 200 is set in the same direction as the conveying direction of the vehicle-mounted roller group 211, that is, both are set along the first conveyor line. The running direction of the running wheel group 522 of the second conveyor vehicle 500 is set perpendicular to the conveying direction of the vehicle-mounted roller group 511, so as to achieve the purpose of steering.

[0075] In a preferred embodiment, taking the first transport vehicle 200 as an example (the second transport vehicle 500 is the same), the support wheel group 212 is arranged at the bottom of the upper frame 21 to stagger the wheel line position corresponding to the wheel travel direction of the traveling wheel group 222. This ensures that the support wheel group 212 and the traveling wheel group 222 can slide separately without interfering with each other, and is also conducive to the high and low climbing action of the support wheel group 212. In a preferred embodiment, the support wheel group 212 is provided with four groups, each group includes a support rod 2121 and a support wheel 2122, the support rod 2121 passes through the lower frame 22 and extends downward, and the support wheel 2122 is installed at the bottom of the support rod 2121.

[0076] The preferred solution is to take the first transport vehicle 200 as an example (the second transport vehicle 500 is the same), the vehicle-mounted roller group 212 is connected to the vehicle-mounted transmission assembly 23, and the vehicle-mounted transmission assembly 23 includes a transmission main shaft 231 and a plurality of helical gear groups; the helical gear group includes a first helical gear 232 and a second helical gear 233 that mesh with each other. The first helical gears 232 of the plurality of helical gear groups are installed on the transmission main shaft 231 at intervals, and the end of the transmission main shaft 231 can be installed by the coupling assembly 74. The second helical gears 233 of the plurality of helical gear groups are installed on the roller shafts of the roller groups 212 one by one. The transmission main shaft 231 is rotated in conjunction with each other, and the first helical gear 232 and the second helical gear 233 are matched to drive the roller group 212 to roll. The vehicle-mounted transmission assembly 53 of the second transport vehicle 500 includes a transmission main shaft 531 and a plurality of helical gear groups in the same way; the helical gear group includes a first helical gear 532 and a second helical gear 533 that mesh with each other, and the structural connection is the same.

[0077] In a preferred embodiment, the transfer bearing transmission assembly 73 includes a transmission main shaft 731 and a plurality of helical gear sets; the helical gear sets include first helical gears 732 and second helical gears 733 that mesh with each other for transmission; the first helical gears 732 of the plurality of helical gear sets are installed on the transmission main shaft 731 at intervals, and the second helical gears 733 of the plurality of helical gear sets are installed on the roller shafts of the transfer bearing roller sets 72 in a one-to-one correspondence. The non-end positions of the transmission main shaft 731 are transmission-connected with a transfer bearing drive assembly 734, and the two end positions of the transmission main shaft 731 are respectively used for connection with the coupling assembly 74. In addition, the connection method of the transfer bearing drive assembly 734 is that the transmission main shaft 731 is composed of two shafts arranged in a line, the inner ends of the two shafts are transmission-connected with the transfer bearing drive assembly 74 through a transmission mechanism, and the outer ends of the two shafts are respectively connected to the coupling assembly 74.

[0078] The preferred solution is to take the first transport vehicle 200 as an example (the second transport vehicle 500 is the same), the first transport vehicle 200 is connected with the first drive assembly 13, and the first drive assembly 13 includes a drive motor 131, two transmission wheel groups 132 and a transmission belt; the drive motor 131 is connected to a transmission wheel group 132, and the two transmission wheel groups 132 are arranged front and back along the conveying direction, and the transmission belt is wound around the two transmission wheel groups 132, and the bottom of the first transport vehicle 200 is connected with the transmission belt. In this way, the drive motor 131 drives, drives the transmission belt to drive, and finally drives the first transport vehicle 200 to transport. The second transport vehicle 500 is the same, and the second transport vehicle 500 is connected with the second drive assembly 43. The second drive assembly 43 includes a drive motor 431, two transmission wheel groups 432 and a transmission belt; and the first drive assembly 13 is connected and driven in the same way. The transmission belt can be a belt, a wire rope, a chain belt, etc.

[0079] The preferred solution is that after the stone is cut once, there are gaps between the slabs of the slab group, in order to facilitate its transportation and subsequent secondary cutting operations. The coupling transfer conveyor 700 also includes a sorting component 75, which has two groups of tightening cylinder groups. The two groups of tightening cylinder groups are arranged above the transfer roller group 72 and are arranged opposite to each other in a direction perpendicular to the roller conveying direction. Therefore, after the transfer roller group 72 receives the slab group, the two groups of tightening cylinder groups of the sorting component 75 are first extended synchronously to merge and close the slabs of the slab group inward for sorting, and then transported to the second transport vehicle 500.

[0080] The preferred solution is that since the slab group is composed of a number of vertical slabs stacked horizontally, in order to facilitate the placement of the slab group when the slab group is cut as a whole, the purpose of accurate and effective cutting can be achieved. The second conveyor line 400 is also equipped with a limit assembly 800, which includes a limit block 81 and a limit cylinder 82; the limit block 81 is arranged above the corresponding vehicle-mounted roller group 511 on the second conveyor 500, and the limit cylinder 82 and the limit block 81 cooperate with each other in the front and back limit setting along the direction of the second conveyor line. In this way, when the second conveyor 500 carries the slab group and transports it backward to the position to be cut, before cutting, the limit cylinder 82 first extends forward to cooperate with the limit block 81 to achieve the front and back tightening limit of the slab group between the two, and then a secondary cutting is performed.
