Description

Technical Field

[0001] The utility model relates to the field of auxiliary components for belt conveying of material distribution, and particularly relates to a belt conveying device for material distribution capable of reducing material loss. Background Technique

[0002] In the prior art, belt conveying of material distribution is widely used in the distribution of materials on a conveyor belt to help achieve material distribution during mechanical transportation. Generally, the span of the existing belt conveying device for material distribution is limited to about 5 meters. If the span is too large, it is easy to tip over, and the smooth operation of the belt for material distribution cannot be guaranteed. Specifically in actual production, in some cases where the distance between the two ends of the material distribution is large, the span of the existing belt conveying device for material distribution cannot meet the material distribution requirements. Therefore, the span of the belt conveying device for material distribution will be increased, which causes the conveying belt of the belt conveying device for material distribution to deviate during the feeding process due to the too long feeding distance of the conveying belt, resulting in materials being easily scattered from the edge position of the conveying belt, and there is a situation of material waste. Content of the Utility Model

Each gasket is vertically provided with mating grooves corresponding to the number of the limit studs, and the outer ends of the mating grooves are all open. At the same time, each gasket is sleeved and clamped outside the limit stud by means of horizontal mating between the mating groove and the limit stud. The limit studs all pass through the lower horizontal part of the corresponding L-shaped mounting bracket in a vertically sliding fit manner, and the lower horizontal part of the L-shaped mounting bracket presses on the top surface of the gasket at the corresponding position. A plurality of lock nuts are coaxially engaged with the top surfaces of the limit studs extending out of the lower horizontal part of the corresponding L-shaped mounting bracket, and the lock nuts are all pressed on the top surface of the horizontal part of the corresponding L-shaped mounting bracket.

[0008] Preferably, the number of lock nuts at the top of each limit stud is two and their rotation directions are opposite.

[0010] Preferably, each of the side-pushing anti-tipping components includes an adjusting stud and a U-shaped wheel bracket. The vertical parts of the L-shaped mounting brackets are vertically arranged longitudinally and are all inserted horizontally in a threaded fit manner with the adjusting studs. The adjusting studs at both sides are away from each other, and the ends of the adjusting studs extending out of the outer sides of the vertical parts of the corresponding L-shaped mounting brackets are coaxially engaged with pressing nuts. The ends of the adjusting studs at both sides close to each other are coaxially rotatably connected to bearing seats II, and U-shaped wheel brackets are fixedly installed on the end faces of the bearing seats II at both sides close to each other. The open positions of the U-shaped wheel brackets at both sides are close to each other, and side supporting rollers are rotatably connected between the upper and lower horizontal parts of the U-shaped wheel brackets at both sides through a supporting rotating shaft.

[0011] Preferably, the parts of the supporting rotating shaft extending out of the corresponding U-shaped wheel brackets are coaxially rotatably connected to bearing seats I, and the bearing seats I are all fixed to the corresponding outsides of the U-shaped wheel brackets, so that the side supporting rollers can all rotate under the restraint of the bearing seats I.

[0012] Preferably, the side supporting rollers are all frustum-shaped rollers with a smaller upper part and a larger lower part.

[0015] When using the above-mentioned material distribution belt conveying device that can reduce material loss, specifically in actual use, since the belt conveying support body at both sides is assembled with the side push anti-tilting component through the heightening adjustment component, and the side push anti-tilting components at both sides are symmetrically arranged. In this way, by using the side support rollers of the side push anti-tilting components at both sides to respectively support the edge of the conveying belt from the corresponding side, it can ensure that the conveying belt will not deviate during the feeding process, preventing material scattering caused by the deviation of the conveying belt. At the same time, by using the side support rollers to support the edge of the conveying belt, it can also cause the edge of the conveying belt to turn up, further preventing material scattering, which is beneficial to reducing material loss during the feeding process. And since turning the adjusting stud of the side push anti-tilting component forward and backward can drive the side support roller to move horizontally, then by the horizontal movement of the side support roller, the force application degree when supporting the edge of the conveying belt can be adjusted, facilitating the adjustment of the side support roller to a supporting state suitable for use. At the same time, since the horizontal position of the side support roller is adjustable, then the side push anti-tilting component can be adapted to conveyer belts of different widths, improving the applicability of the side push anti-tilting component. And since the heightening adjustment component includes the limit stud vertically fixed on the top surface of the bottom plate and multiple gaskets, then by the transverse cooperation of the fitting groove and the limit stud, the gasket can be smoothly sleeved and clamped outside the limit stud. At the same time, by the horizontal sliding-off of the fitting groove along the limit stud, the gasket can be quickly detached from the outside of the limit stud. The combination and detachment methods of the gasket outside the limit stud are simple and easy to implement. Then, it is convenient to adjust the position height of the side push anti-tilting component by adjusting the stacking number of the gaskets outside the limit stud, ensuring that the side push anti-tilting component can be adapted to conveyer belts at different position heights, further improving the applicability of the side push anti-tilting component.

[0016] The beneficial effects are as follows: 1. On both sides of the belt conveyor support body of the present utility model, side push anti-tilting components are assembled and installed through the heightening adjustment components, and the side push anti-tilting components on both sides are symmetrically arranged. In this way, by using the side support rollers of the side push anti-tilting components on both sides to respectively support the edge of the conveyor belt from the corresponding side, it can ensure that the conveyor belt does not deviate during the feeding process, prevent material scattering caused by the deviation of the conveyor belt, and at the same time, by using the side support rollers to support the edge of the conveyor belt, it can also cause the edge of the conveyor belt to turn up, further preventing material scattering, which is beneficial to reducing material loss during the feeding process;

[0017] 2. By rotating the adjusting stud forward and backward, the side support roller can be driven to move horizontally. Subsequently, by the horizontal movement of the side support roller, the force application degree when supporting the edge of the conveyor belt can be adjusted, facilitating the adjustment of the side support roller to a supporting state that meets the use requirements. At the same time, since the horizontal position of the side support roller is adjustable, the side push anti-tilting component can be adapted to conveyor belts of different widths, improving the applicability of the side push anti-tilting component;

[0018] 3. The heightening adjustment component includes a limit stud vertically fixed on the top surface of the bottom plate and multiple gaskets. Subsequently, by horizontally matching the mating groove with the limit stud, the gasket can be smoothly sleeved and clamped outside the limit stud. At the same time, by horizontally sliding the mating groove along the limit stud, the gasket can be quickly detached from the outside of the limit stud. The combination and detachment methods of the gasket outside the limit stud are simple and easy to implement. Subsequently, it is convenient to adjust the position height of the side push anti-tilting component by adjusting the stacking quantity of the gaskets outside the limit stud, ensuring that the side push anti-tilting component can be adapted to conveyor belts at different position heights, further improving the applicability of the side push anti-tilting component.

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0029] See Figures 1 - 6As shown in the figure, the utility model provides a material distributing belt conveying device capable of reducing material loss, which includes a belt conveying support body 4. At the top of the belt conveying support body 4 on both sides, a plurality of bottom plates 3 are assembled and installed. On the top surface of each bottom plate 3, a heightening and adjusting component 2 is assembled and arranged. And a plurality of heightening and adjusting components 2 at the same side are evenly arranged in the length direction of the belt conveying support body 4. Specifically, each heightening and adjusting component 2 includes a limit stud 201 and a gasket 204. On the top surface of each bottom plate 3, several limit studs 201 are vertically fixed. The number of gaskets 204 is multiple and they are stacked on top of each other up and down. Each gasket 204 is vertically provided with a mating groove 203 corresponding to the number of limit studs 201. And the outer ends of the mating grooves 203 are all open. At the same time, each gasket 204 is sleeved and clamped outside the limit stud 201 in a way of horizontal cooperation between the mating groove 203 and the limit stud 201. Each limit stud 201 passes through the lower horizontal part of the corresponding L-shaped mounting bracket 1 in a vertical sliding fit manner. And the lower horizontal part of each L-shaped mounting bracket 1 presses on the top surface of the corresponding gasket 204. On the top surface of each limit stud 201 extending out of the lower horizontal part of the corresponding L-shaped mounting bracket 1, several locking nuts 202 are coaxially engaged. And each locking nut 202 presses on the top surface of the horizontal part of the corresponding L-shaped mounting bracket 1. The purpose of such a setting is that the gasket 204 can be smoothly sleeved and clamped outside the limit stud 201 through the horizontal cooperation between the mating groove 203 and the limit stud 201. At the same time, the gasket 204 can be quickly detached from the outside of the limit stud 201 through the way that the mating groove 203 slides horizontally along the limit stud 201. The combination and detachment methods of the gasket 204 outside the limit stud 201 are simple and easy to implement. Then it is convenient to adjust the position height of the side push anti-tilting component 5 by adjusting the stacking number of the gaskets 204 outside the limit stud 201, ensuring that the side push anti-tilting component 5 can adapt to the conveying belts at different position heights.

[0030] See Figures 1 - 3As shown in the figure, L-shaped mounting brackets 1 are fixedly combined at the tops of the elevation adjustment components 2. Side push anti-tipping components 5 are combined and arranged on the L-shaped mounting brackets 1, and the side push anti-tipping components 5 at both sides are symmetrically arranged. By means of the side push anti-tipping components 5 at both sides respectively propping up the edges of the conveyor belt from the corresponding sides, it is ensured that the conveyor belt does not deviate during the feeding process. Specifically, each side push anti-tipping component 5 includes an adjusting stud 508 and a U-shaped wheel frame 503. The vertical parts of the L-shaped mounting brackets 1 are vertically arranged longitudinally and the adjusting studs 508 are inserted transversely in a threaded fit manner. The ends of the adjusting studs 508 at both sides, which are far from each other and extend outside the vertical parts of the corresponding L-shaped mounting brackets 1, are coaxially engaged with compression nuts 507. The ends of the adjusting studs 508 at both sides, which are close to each other, are coaxially rotatably connected to bearing seats II 506, and U-shaped wheel frames 503 are fixedly installed on the end faces of the bearing seats II 506 at both sides, which are close to each other. The open positions of the U-shaped wheel frames 503 at both sides are close to each other, and side support rollers 504 are rotatably connected between the upper and lower horizontal parts of the U-shaped wheel frames 503 at both sides through support rotating shafts 501. The function of such a setting is that, firstly, by means of the side support rollers 504 of the side push anti-tipping components 5 at both sides respectively propping up the edges of the conveyor belt from the corresponding sides, it can be ensured that the conveyor belt does not deviate during the feeding process, preventing the situation of material scattering due to the deviation of the conveyor belt. At the same time, by screwing the adjusting stud 508 forward and backward, the side support roller 504 can be driven to move horizontally. Then, by means of the horizontal movement of the side support roller 504, the force application degree when propping up the edge of the conveyor belt can be adjusted, facilitating the adjustment of the side support roller 504 to a propping state that meets the use requirements. Moreover, since the horizontal position of the side support roller 504 is adjustable, the side push anti-tipping component 5 can be adapted to conveyor belts of different widths for use.

[0031] See Figures 1 - 6 As shown in the figure, the following optimizations are respectively carried out on the elevation adjustment component 2 and the side push anti-tipping component 5. Specifically for the elevation adjustment component 2, the number of locking nuts 202 at the top of each limit stud 201 is two and their rotation directions are opposite, so as to enable the two locking nuts 202 of the same limit stud 201 to form a Tang's anti-loosening thread, ensuring that the locking nut 202 will not loosen naturally after being tightened. At the same time, optionally, a plurality of reinforcing rib plates 101 are fixedly connected between the horizontal part and the vertical part of the L-shaped mounting bracket 1, so as to enhance the overall stability and reliability of the L-shaped mounting bracket 1 through the reinforcing rib plates 101.

[0032] Specifically for the side-pushing anti-tilting component 5, bearing seats 502 are coaxially rotatably connected to the portions of the support rotating shaft 501 extending out of the corresponding U-shaped wheel frame 503, and the bearing seats 502 are fixed to the corresponding outer parts of the U-shaped wheel frame 503, so as to enable the side supporting rollers 504 to rotate circumferentially under the constraint of the bearing seats 502. Optionally, the side supporting rollers 504 are all frustum-shaped rollers with a smaller upper part and a larger lower part, so that the style design of the side supporting rollers 504 can meet the use requirements of pushing the conveyor belt from the side. Further, handwheels 509 are coaxially installed at the outer ends of the adjusting studs 508 at both sides away from each other, and the compression nuts 507 are all hand-tightening knurled nuts. With such a setting, first, it is convenient to drive the rotation of the adjusting studs 508 by applying force to the handwheels 509, and at the same time, it is convenient for the compression nuts 507 to be directly screwed by hand. Furthermore, guiding holes 5010 are transversely formed at the positions of the U-shaped wheel frame 503 corresponding to the upper and lower positions of the adjusting studs 508, and guide rods 505 are coaxially inserted into the guiding holes 5010 in a transverse sliding fit manner, and the end portions of the guide rods 505 at both sides close to each other are fixed to the outer parts of the corresponding U-shaped wheel frame 503. With such a setting, during the process of rotating the adjusting studs 508 to drive the U-shaped wheel frame 503 and the side supporting rollers 504 to move, guiding and deviation correction can be carried out by the axial sliding of the guide rods 505 along the guiding holes 5010, preventing the situation that the side supporting rollers 504 are axially deflected due to the U-shaped wheel frame 503 rotating together with the adjusting studs 508.

[0033] With the above structure, specifically in actual use, since the belt conveyor support body 4 at both sides is combined and installed with the side push anti-tilting component 5 through the heightening adjustment component 2, and the side push anti-tilting components 5 at both sides are symmetrically arranged, the side supporting rollers 504 of the side push anti-tilting components 5 at both sides can respectively support the edge of the conveyor belt from the corresponding side, so as to ensure that the conveyor belt will not deviate during the feeding process, prevent the situation of material scattering due to the deviation of the conveyor belt, and at the same time, by means of the side supporting rollers 504 supporting the edge of the conveyor belt, the edge of the conveyor belt can be turned up to further prevent the situation of material scattering, which is beneficial to reducing the material loss during the feeding process. And since the side push anti-tilting component 5 can drive the side supporting roller 504 to move horizontally by screwing the adjusting screw 508 of the side push anti-tilting component 5 forward and backward, then by means of the horizontal movement of the side supporting roller 504, the force application degree when supporting the edge of the conveyor belt can be adjusted, which is convenient to adjust the side supporting roller 504 to a supporting state suitable for use. At the same time, since the horizontal position of the side supporting roller 504 is adjustable, the side push anti-tilting component 5 can be adapted to conveyor belts of different widths, improving the applicability of the side push anti-tilting component 5. And since the heightening adjustment component 2 includes the limit screw 201 vertically fixed on the top surface of the bottom plate 3 and multiple gaskets 204, then the gasket 204 can be smoothly sleeved and clamped outside the limit screw 201 by the transverse cooperation of the mating groove 203 and the limit screw 201. At the same time, the gasket 204 can be quickly detached from the outside of the limit screw 201 by the horizontal sliding of the mating groove 203 along the limit screw 201. The combination and detachment methods of the gasket 204 outside the limit screw 201 are simple and easy to implement. Then, it is convenient to adjust the position height of the side push anti-tilting component 5 by adjusting the stacking number of the gaskets 204 outside the limit screw 201, ensuring that the side push anti-tilting component 5 can be adapted to conveyor belts at different position heights, and further improving the applicability of the side push anti-tilting component 5.

[0034] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
