Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, in particular to a variable speed conveyor with a sensor control system. Background Art

[0002] Variable-speed conveyors dynamically adjust conveying speeds to meet efficiency, precision, and energy consumption requirements under varying operating conditions. They are a core component of modern industrial automation. Their technical implementation primarily involves mechanical speed change, hydraulic transmission, and variable frequency control, making them suitable for a variety of applications, including mining, production lines, and logistics. There are many types of conveyors, primarily categorized by structure and operating principle: belt, bucket, chain, spiral, and vibrating.

[0003] Bucket conveyors include chain bucket conveyors and bucket elevators. Among them, chain bucket conveyors are equipment that uses a bucket running along a track to transport materials horizontally or obliquely. Due to its flexible layout, large conveying capacity, long service life, low maintenance, low operating cost, and large conveying slope, it is widely used in power plants, mining, metallurgy, coal and other industries to transport various loose materials.

[0004] After integrating sensors, controllers and variable speed drive technology to achieve intelligent speed regulation and precise control of material transportation, the chain bucket conveyor can be made into a variable speed conveyor with a sensor control system. It is a key equipment in the field of industrial automation. However, when faced with irregular feeding, the existing variable speed conveyor only uses a sensor control system to change the speed of material transportation. The unloaded discharge hopper will continue to idle with the variable speed conveyor, resulting in a waste of resources. Summary of the Invention

[0005] (1) Technical problems solved The purpose of the embodiment of the present invention is to provide a variable-speed conveyor with a sensor control system, which aims to solve the problem that when facing irregular loading, the existing variable-speed conveyor only uses a sensor control system to change the speed of conveying materials, and the unloaded discharge hopper will still continue to idle with the variable-speed conveyor, thereby causing waste of resources.

[0006] (2) Technical solution Specifically: a variable-speed conveyor with a sensor control system, comprising a plurality of placement platforms for placing a plurality of discharge hoppers, and a support frame mounted on a variable-speed conveyor body, wherein the plurality of placement platforms are arranged on the side of the variable-speed conveyor body; the placement platforms are used to provide a plurality of discharge hoppers of various sizes for the variable-speed conveyor body through a manipulator, and the discharge hoppers and the variable-speed conveyor body are detachably mounted; in the face of irregular feeding, when materials are fed, the manipulator will be used to place the plurality of discharge hoppers on the placement platforms one after another detachably on the variable-speed conveyor body according to the amount of material fed. On the machine body, the variable-speed conveyor body adjusts the placement number of multiple detachably assembled discharge hoppers according to the material loading amount, so as to flexibly cope with irregular loading conditions; it is beneficial for the variable-speed conveyor body to flexibly adjust the discharge hopper counterweight on the basis of variable-speed material conveying, so as to avoid the discharge hopper from idling due to the failure of the discharge hopper to timely adjust the material loading amount according to the change; since multiple placement platforms can correspond to the placement of multiple discharge hoppers of various sizes, the number of detachable assemblies of multiple discharge hoppers on the variable-speed conveyor body can be coordinated to further flexibly cope with irregular loading conditions and avoid idling.

[0007] The technical solution of this application is further described below: In one embodiment, the variable-speed conveyor body is equipped with a plurality of spacing adjustment members, which are distributed in an array along the variable-speed conveyor body; the plurality of spacing adjustment members can be driven by the variable-speed conveyor body to move in a closed-loop cycle; the spacing adjustment members are detachably mounted on the discharge hopper; the spacing adjustment members are used to adjust the spacing L between the plurality of discharge hoppers.

[0009] Furthermore, the adsorption positioning frame includes a support plate and a telescopic part B, an adsorption plate is laid flat on the support plate, and multiple groups of electromagnetic coils are laid flat on the adsorption plate. By turning on and off the power of the multiple groups of electromagnetic coils, the adsorption plate can be switched to be magnetic; the discharge hopper is placed on the adsorption plate for magnetic adsorption to complete the detachable installation of the discharge hopper; the telescopic part B is fixed on the support plate, and the end of the telescopic part B away from the support plate is fixed on the support positioning frame; the telescopic part B is fixed with a telescopic part A perpendicular to it, and the end of the telescopic part A away from the telescopic part B is fixed with a support wheel.

[0010] The telescopic member B is used to adjust the spacing L of the multiple discharge hoppers through its own telescopic movement; the telescopic member A is used to adjust the spacing by following the variable speed conveyor body in the closed-loop cyclic movement overshoot process to adapt to the curvature change of the variable speed conveyor body through its own telescopic movement. The discharge hopper is detachably magnetically adsorbed and mounted on the adsorption plate; the telescopic member B is used to adjust the spacing L of the multiple discharge hoppers through its own telescopic movement, so as to flexibly cope with irregular intermittent feeding, and cope with the situation where the speed of the variable speed conveyor body after the speed change does not match the irregular feeding speed; from the number of discharge hoppers installed to the adjustment of the spacing L of the multiple discharge hoppers, and then to the adaptive matching of the speed of the variable speed conveyor body after the speed change, the variable speed conveyor with a sensor control system can be flexible, efficient, and energy-saving adapted to irregular feeding such as single feeding amount and feeding speed; The discharge hopper is detachably mounted on an adsorption plate using magnetic adsorption. When the conveyor changes speed, the magnetic force provides flexible constraints, allowing the hopper to produce micro-displacements. The interaction between the material inertia force and the magnetic attraction force forms damping energy dissipation. Compared with mechanical rigid fixation, the system vibration amplitude is reduced, the conveyor belt bearing wear is reduced, and the equipment life is extended. The magnetic attraction damping effect is achieved to reduce vibration loss.

[0011] Furthermore, the supporting positioning frame includes a crossbeam, which is mounted on the variable-speed conveyor body; a lifting plate is fixed on the crossbeam, and a fixed platform is installed on the lifting plate; and the adsorption positioning frame is fixed on the fixed platform.

[0012] In one embodiment, the variable speed conveyor body includes a transmission chain and a support body, the transmission chain is installed outside the support body, and the transmission chain power transmission is connected to the power device; the support body outside the transmission chain is provided with a baffle; the power device includes a drive motor and a reduction motor.

[0013] In one embodiment, the support frame includes a base plate, a support platform is fixed on the base plate, and two positioning plates are fixed on one end of the support platform, and the two positioning plates are distributed in parallel; the variable speed conveyor body is rotatably assembled between the two positioning plates through a positioning shaft fixed at its end.

[0014] Furthermore, the support frame also includes two lifting legs, which are distributed on both sides of the variable speed conveyor body; one end of the lifting leg is rotatably assembled on the variable speed conveyor body, and the other end is fixed on the support platform; the lifting leg includes a hydraulic cylinder and a rotating plate, the rotating plate is fixed to the end of the hydraulic cylinder, and the other end of the rotating plate away from the hydraulic cylinder is rotatably assembled on the variable speed conveyor body.

[0015] In one embodiment, the discharge hopper includes a base plate, two side baffles and two vertical plates, and the two side baffles and the two vertical plates are rectangularly arranged on the base plate; elastic rubber belts are laid inside the two side baffles and the two vertical plates; the discharge hopper also includes a positioning frame and four lifting columns, and the positioning frame is arranged on the top of the two side baffles and the two vertical plates; the four lifting columns are distributed at the four corners of the base plate, and the lifting columns and the base plate are vertically distributed; the lifting columns are electric telescopic rods, and the end of the lifting columns away from the base plate is rotatably assembled on the positioning frame; a plurality of lifting baffles are movably interspersed on the side baffle, and the plurality of lifting baffles are distributed in a side-by-side array; the end of the lifting baffle away from the side baffle is rotatably assembled on the positioning frame.

[0016] (3) Beneficial effects Compared with the prior art, the variable speed conveyor with a sensor control system of the present invention has the following advantages: 1) When facing irregular feeding, when materials are being fed, the manipulator will place multiple hoppers on the placement table one after another on the variable-speed conveyor body in a detachable manner according to the feeding amount of the materials. This will enable the variable-speed conveyor body to adjust the number of detachably assembled hoppers according to the feeding amount of the materials, so as to flexibly deal with irregular feeding. This is beneficial for the variable-speed conveyor body to flexibly adjust the counterweight of the hopper on the basis of variable-speed material conveying, so as to avoid the hopper from idling due to its inability to timely adjust the feeding amount of the materials. 2) Since multiple placement tables can be used to place multiple hoppers of various sizes, the number of detachable assemblies of multiple hoppers on the variable-speed conveyor body can be adjusted to further flexibly cope with irregular loading situations and avoid idling; 3) When facing irregular feeding, the discharge hopper is detachably magnetically attached to the adsorption plate; the spacing L between the multiple discharge hoppers is adjusted by the extension and contraction of the telescopic member B itself, so as to flexibly cope with irregular intermittent feeding and the mismatch between the speed of the variable speed conveyor body after the speed change and the irregular feeding speed; from the number of discharge hoppers installed to the adjustment of the spacing L between the multiple discharge hoppers, and then to the adaptive matching of the speed of the variable speed conveyor body after the speed change, the variable speed conveyor with a sensor control system can be flexibly, efficiently and energy-savingly adapted to irregular feeding such as single feeding amount and feeding speed; 4) The discharge hopper is detachably magnetically mounted on the adsorption plate. When the conveyor changes speed, the magnetic force provides flexible constraints, allowing the hopper to produce micro-displacement. The interaction between the material inertia force and the magnetic attraction force forms damping energy dissipation. Compared with mechanical rigidity, the system vibration amplitude is reduced, the conveyor belt bearing wear is reduced, and the equipment life is extended. The magnetic attraction damping effect reduces vibration loss. 5) Real-time adjustment of the number and spacing of hoppers ensures that the total system mass (hoppers + materials) always approaches the optimal load range. When the load is light, the number of hoppers is reduced to reduce ineffective load; when the load is heavy, the density of hoppers is increased to avoid motor overload. Motor power fluctuations are reduced to avoid energy waste caused by "a big horse pulling a small cart". The conveyor's inverter can stably operate in the high-efficiency speed range, achieving comprehensive energy savings that exceed the expectations of simple speed control. Dynamic counterweight is achieved to optimize drive energy consumption. 6) By reducing the spacing L (e.g., L→0), the discrete hoppers visually form a "quasi-continuous conveying surface." With such a short spacing, the material flows between the hoppers in a nearly continuous manner. Combined with the conveyor speed change, this simulates the effect of a continuous conveyor belt. When handling fragmented material, the efficiency approaches that of a continuous conveying system such as a belt conveyor, breaking through the bottleneck of intermittent conveying. It can seamlessly connect with downstream continuous processing equipment such as filling machines, eliminating the need for additional buffer bins and improving compatibility. 7) On the basis of controlling the inclination of the variable-speed conveyor body through the hydraulic cylinder on the lifting leg, the two lifting columns on one side are extended and the two lifting columns on the other side are shortened, so that multiple lifting baffles are distributed in an inclined array; the discharge hopper is tilted to different degrees to cope with the situation that the material is easily affected by gravity and distributed in an inclined shape inside the discharge hopper during the tilted material transfer process of the variable-speed conveyor body, thereby avoiding material spillage.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. The specific implementation of the present invention is described in detail below with reference to the specific embodiments.

[0020] In the embodiment of the present invention, Figure 1 and Figure 2 As shown: a variable speed conveyor with a sensor control system, comprising a plurality of placement platforms 1 for placing a plurality of discharge hoppers 5, and mounted on a variable speed conveyor body 3 via a support frame 2, wherein the plurality of placement platforms 1 are arranged on the side of the variable speed conveyor body 3; The placement table 1 is used to provide a plurality of discharge hoppers 5 of various sizes for the variable speed conveyor body 3 through a manipulator. The discharge hoppers 5 are detachably mounted on the variable speed conveyor body 3. What needs to be explained about the "manipulator" is that the manipulator belongs to the existing technology and can be found through existing literature and web pages, and its working principle can also be known through conventional means; it can also be purchased directly on the market, and does not fall within the scope of protection of the present invention, so it will not be explained in detail here; and the manipulator can also be replaced by a splint, or can be replaced by a structure in which a hydraulic cylinder and a lifting plate cooperate, etc. The specific structure is not limited, as long as it can provide multiple hoppers 5 of various sizes for the variable-speed conveyor body 3 through the manipulator; When facing the irregular feeding situation, when materials start to be fed, the multiple discharge hoppers 5 on the placement table 1 are detachably placed on the variable-speed conveyor body 3 one after another according to the feeding amount of the materials through the manipulator, so that the variable-speed conveyor body 3 can adjust the placement number of the multiple detachably assembled discharge hoppers 5 according to the feeding amount of the materials, so as to flexibly deal with the irregular feeding situation; it is beneficial for the variable-speed conveyor body 3 to flexibly adjust the counterweight of the discharge hopper 5 on the basis of variable-speed conveying of materials, so as to avoid the situation that the discharge hopper 5 cannot be idling in time according to the change of the feeding amount of the materials; This solves the problem that when the material is not loaded regularly, the existing variable-speed conveyor only uses the sensor control system to change the speed of the material, and the unloaded hopper will continue to run idle with the variable-speed conveyor, thus causing a waste of resources. Since multiple placement tables 1 can be used to place multiple discharge hoppers 5 of various sizes, the number of detachable assemblies of multiple discharge hoppers 5 on the variable-speed conveyor body 3 can be coordinated to further flexibly cope with irregular feeding situations and avoid idling.

[0021] In another embodiment of the present invention, Figure 1-Figure 3 and Figure 7 As shown: the variable speed conveyor body 3 is equipped with a plurality of spacing adjustment members 4, and the plurality of spacing adjustment members 4 are distributed in an array along the variable speed conveyor body 3; the plurality of spacing adjustment members 4 can be driven by the variable speed conveyor body 3 to perform closed-loop circulation; the spacing adjustment members 4 and the discharge hopper 5 are detachably mounted; The spacing adjusting member 4 is used to adjust the spacing L between the plurality of discharge hoppers 5 .

[0022] In another embodiment of the present invention, Figure 1-Figure 3 and Figure 10-12 As shown: the spacing adjustment member 4 includes an adsorption positioning frame 41 and a support positioning frame 42; the support positioning frame 42 is mounted on the variable speed conveyor body 3 and can follow the variable speed conveyor body 3 to perform closed-loop circulation movement; The adsorption positioning frame 41 is assembled on the supporting positioning frame 42 , and the adsorption positioning frame 41 is used for detachable installation with the discharge hopper 5 .

[0023] Further, such as Figure 10-12As shown: the adsorption positioning frame 41 includes a support plate 411 and a telescopic member B415. The support plate 411 is flatly provided with an adsorption plate 412. The adsorption plate 412 is flatly provided with multiple sets of electromagnetic coils. By turning on and off the power of the multiple sets of electromagnetic coils, the adsorption plate 412 is switched to be magnetic. The discharge hopper 5 is placed on the adsorption plate 412 for magnetic adsorption, thereby completing the detachable installation of the discharge hopper 5. It is necessary to further explain that electromagnetic coils are prior art and can be found through existing literature and websites, and their working principles can also be learned through conventional means. They can also be purchased directly on the market and are not protected by the present invention, so they will not be elaborated on here. For example, the magnetic field strength H generated by an energized coil is proportional to the product of the number of coil turns N and the current I (formula: H=N*I / L, where L is the magnetic path length). When the magnetic field passes through a magnetic material (such as an iron core), the magnetic induction intensity B is significantly enhanced (B=μ*H, where μ is the magnetic permeability), thereby generating an adsorption force. The adsorption strength of the electromagnetic coil depends mainly on the synergistic effect of N*I (ampere-turns) and the properties of the magnetic core material. The telescopic member B415 is fixed on the support plate 411, and the end of the telescopic member B415 away from the support plate 411 is fixed on the support positioning frame 42; the telescopic member B415 is fixed with a telescopic member A413 perpendicular to it, and the end of the telescopic member A413 away from the telescopic member B415 is fixed with a support wheel 414.

[0024] like Figure 10-12 As shown: the telescopic part B415 is used to adjust the spacing L of multiple discharge hoppers 5 through its own telescopic movement; the telescopic part A413 is used to adapt to the curvature change of the variable speed conveyor body 3 during the closed-loop cyclic movement overshoot of the spacing adjustment part 4 following the variable speed conveyor body 3 through its own telescopic movement.

[0025] Therefore, when facing irregular feeding, the discharge hopper 5 is detachably mounted on the adsorption plate 412 by magnetic adsorption; the spacing L between the multiple discharge hoppers 5 is adjusted by the telescopic member B415 itself to flexibly cope with irregular intermittent feeding, as well as the mismatch between the speed of the variable-speed conveyor body 3 after the speed change and the irregular feeding speed; from the number of discharge hoppers 5 installed to the adjustment of the spacing L between the multiple discharge hoppers 5, and then to the adaptive matching of the speed of the variable-speed conveyor body 3 after the speed change, the variable-speed conveyor with a sensor control system is flexible, efficient, and energy-saving in adapting to irregular feeding, such as single feeding amount and feeding speed; Finally, the spacing adjustment member 4 utilizes the support positioning frame 42 to drive the adsorption positioning frame 41 to follow the variable speed conveyor body 3 to perform a closed-loop circular movement. The telescopic member A413 can adapt to the curvature change of the variable speed conveyor body 3 through its own telescopic movement during the overshoot process of the closed-loop circular movement of the spacing adjustment member 4 following the variable speed conveyor body 3.

[0026] It needs to be further explained that the telescopic parts A413 and B415 can be hydraulic telescopic rods, pneumatic telescopic rods or electric telescopic rods, etc. There is no restriction on the specific structure, as long as they can be used for telescopic extension. They are all existing technologies and can be found through existing literature and web pages. Their working principles can also be known through conventional means. They can also be purchased directly on the market, and are not protected by the present invention, so they will not be elaborated here.

[0027] In summary, we can see that: The discharge hopper 5 is detachably mounted on the adsorption plate 412 by magnetic attraction. When the conveyor changes speed, the magnetic force provides flexible constraints, allowing the hopper to produce micro-displacement. The interaction between the material inertia force and the magnetic attraction force forms a damping energy dissipation. Compared with mechanical rigid fixation, the system vibration amplitude is reduced, the wear of the conveyor belt bearing is reduced, and the equipment life is extended. The magnetic attraction damping effect reduces vibration loss. Real-time adjustment of the number and spacing of the hoppers 5 ensures that the total system mass (hoppers 5 + materials) always approaches the optimal load range. The number of hoppers 5 is reduced under light loads to reduce ineffective loads; under heavy loads, the density of the hoppers 5 is increased to avoid motor overload. Motor power fluctuations are reduced to avoid energy waste from a "big horse pulling a small cart" phenomenon. The conveyor's inverter can stably operate in the high-efficiency speed range, achieving comprehensive energy savings that exceed the expectations of simple variable speed control. Dynamic counterweighting is achieved to optimize drive energy consumption. By reducing the spacing L (e.g., L→0), the discrete hoppers visually form a "quasi-continuous conveying surface." With extremely short spacing, the material flows approximately continuously between the five discharge hoppers. Combined with conveyor speed changes, the system simulates the effect of a continuous conveyor belt. When processing fragmented material, the system's efficiency approaches that of a continuous conveying system such as a belt conveyor, breaking through the bottleneck of intermittent conveying. The system can seamlessly connect to downstream continuous processing equipment such as filling machines, eliminating the need for additional buffer bins and improving compatibility.

[0028] In another embodiment of the present invention, Figure 1 、 Figure 10 and Figure 12 As shown: the supporting positioning frame 42 includes a crossbeam 423, which is mounted on the variable-speed conveyor body 3; a lifting plate 422 is fixed on the crossbeam 423, and a fixed platform 421 is installed on the lifting plate 422; the adsorption positioning frame 41 is fixed on the fixed platform 421 (specifically, the end of the telescopic member B415 is fixed on the fixed platform 421).

[0029] In another embodiment of the present invention, Figure 4-Figure 6As shown: the variable speed conveyor body 3 includes a transmission chain 33 and a support body 35. The transmission chain 33 is installed outside the support body 35, and the transmission chain 33 is connected to the power device 31 through power transmission; the support body 35 outside the transmission chain 33 is provided with a baffle 34; the power device 31 includes a drive motor and a reduction motor.

[0030] It needs to be further explained that: except for the power device 31, the transmission chain 33, the baffle 34 and the support body 35, the variable speed conveyor body 3 not described belongs to the existing technology, which can be found through existing literature and web pages, and its working principle can also be known through conventional means; it can also be purchased directly on the market, and does not belong to the protection of the present invention, so it will not be elaborated here.

[0031] In another embodiment of the present invention, Figure 4-Figure 6 As shown: the support frame 2 includes a base plate 22, a support platform 23 is fixed on the base plate 22, and two positioning plates 21 are fixed at one end of the support platform 23, and the two positioning plates 21 are distributed in parallel; the variable speed conveyor body 3 is rotatably assembled between the two positioning plates 21 through a positioning shaft 32 fixed at its end.

[0032] Further, such as Figure 4-Figure 6 As shown: the support frame 2 also includes two lifting legs 24, which are distributed on both sides of the variable speed conveyor body 3; one end of the lifting leg 24 is rotatably assembled on the variable speed conveyor body 3, and the other end is fixed on the support platform 23; The lifting legs 24 include a hydraulic cylinder and a rotating plate. The rotating plate is fixed to the end of the hydraulic cylinder, and the other end of the rotating plate away from the hydraulic cylinder is rotatably assembled on the variable speed conveyor body 3.

[0033] Therefore, by controlling the hydraulic cylinder on the lifting legs 24, the inclination of the variable-speed conveyor body 3 can be regulated, and the material transfer inclination of the variable-speed conveyor body 3 can be adjusted.

[0034] In another embodiment of the present invention, Figure 7-Figure 9 As shown: the discharge hopper 5 includes a base plate, two side baffles 54 and two vertical plates 55, the two side baffles 54 and the two vertical plates 55 are arranged on the base plate in a rectangular shape; elastic rubber belts are laid inside the two side baffles 54 and the two vertical plates 55; The discharge hopper 5 also includes a positioning frame 51 and four lifting columns 52. The positioning frame 51 is set on the top of two side baffles 54 and two vertical plates 55. The four lifting columns 52 are distributed at the four corners of the base plate. The lifting columns 52 are perpendicular to the base plate. The lifting columns 52 are electric telescopic rods. The end of the lifting column 52 away from the base plate is rotatably assembled on the positioning frame 51. A plurality of lifting baffles 53 are movably inserted into the side baffle 54 , and the plurality of lifting baffles 53 are arranged in a side-by-side array; one end of the lifting baffle 53 away from the side baffle 54 is rotatably assembled on the positioning frame 51 .

[0035] Therefore, on the basis of completing the adjustment of the material transfer inclination of the variable-speed conveyor body 3 through the control of the hydraulic cylinder on the lifting support leg 24, the two lifting columns 52 on one side are extended and the two lifting columns 52 on the other side are shortened, so that multiple lifting baffles 53 are distributed in an inclined array; the discharge hopper 5 is tilted to different degrees, so as to cope with the situation that the material is easily affected by gravity and distributed in an inclined shape inside the discharge hopper 5 during the inclined material transfer process of the variable-speed conveyor body 3, and to avoid material spillage.

[0036] In the description of the present invention, unless otherwise specified, "plurality" means two or more. Although the embodiments of the present invention have been shown and described in the description of the present invention, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
