Description

Technical Field

[0001] This application relates to the field of material transport, and in particular to an adjustable pitch particulate conveyor belt. Background Technology

[0002] Currently, various transfer methods are commonly used in material handling, such as screw conveyor, conveyor belt conveyor, pipeline transportation, overhead conveyor, and unmanned forklift transportation. The appropriate transportation method is selected based on the specific material being transported. When transporting granular materials into processing equipment, due to the small size and tendency to roll, manual or mechanical handling of the drummed raw materials is usually required, or the material can be transported using a screw conveyor.

[0003] Regarding the aforementioned technologies, feeding via a bucket is not suitable for equipment that requires continuous and uninterrupted feeding over a long period of time. When feeding granular materials via a screw feeder, the screw may damage the material. When transporting materials via a conveyor belt, leakage or jamming may occur, thereby damaging the equipment. Utility Model Content

[0004] In order to achieve continuous and intermittent feeding of granular materials to the equipment, and to effectively adjust the feeding amount per unit time, this application provides an adjustable-pitch granular conveyor belt.

[0005] This application provides an adjustable-pitch particulate conveyor belt, which adopts the following technical solution:

[0006] An adjustable-pitch particulate conveyor belt includes a frame, a base plate along the length of the frame, guard plates on both sides of the base plate in the width direction, transmission gears and drive motors at both ends of the frame in the length direction of the base plate, a chain passing between the transmission gears, a plurality of slots on the side of the chain near the base plate, the slots between the chains corresponding one to one, a baffle detachably connected in the slot, a feeding assembly at one end of the base plate, and a material storage assembly for temporarily blocking material from entering the base plate.

[0007] By adopting the above technical solution, when transporting granular materials, the feeding component conveys the material to the substrate, the transmission gear drives the chain to rotate, and the guard plate restricts the material between two baffles. The operator controls different interval sizes by adjusting the position of the baffles on the chain, thereby controlling the amount of material of different sizes in different intervals, realizing the continuous and sustainable supply of granular materials to the equipment, and effectively adjusting the feeding amount per unit time.

[0008] Optionally, the feeding assembly includes a feeding pipe with its outlet located above the substrate inlet. The feeding pipe has a compressed air nozzle inside, which points towards the outlet of the feeding pipe. The compressed air nozzle is equipped with an air compressor that supplies compressed air to it.

[0009] By adopting the above technical solution, compressed air is sprayed into the feed pipe through a nozzle, creating a negative pressure at the inlet of the feed pipe. This allows particulate matter at the inlet of the feed pipe to be drawn into the feed pipe and discharged to the outlet of the feed pipe, thereby achieving the supply of materials to the substrate.

[0010] Optionally, a filter grid is provided on the upper side of the feed pipe, a filter assembly is provided above the feed pipe, the filter assembly is detachably connected to the feed pipe, and a shielding curtain is provided on the side of the feed pipe near the substrate.

[0011] By adopting the above technical solution, the granular material is guided and restricted when it is discharged from the feed pipe by setting up a shielding curtain, so that it can fall relatively smoothly. The filter grid and filter components can effectively adsorb dust and impurities in the granular material, while the compressed air is discharged to ensure the supply of material.

[0012] Optionally, the material storage assembly includes a storage plate and a plate-turning motor. The storage plate is rotatably connected to the inner wall of the feed pipe. The plate-turning motor is used to control the rotation of the storage plate. A pressure sensor is provided on the side of the storage plate near the inlet of the feed pipe.

[0013] By adopting the above technical solution, if it is necessary to feed material at intervals on the baffle, the storage plate can be turned down by the flip motor. At this time, the material will accumulate at the storage plate. When the pressure at the pressure sensor reaches the set value, the storage plate will flip open to continue feeding.

[0014] Optionally, the filter assembly includes a housing, a filter element, and a flow sensor. The housing has a locking block on the side near the feed pipe, and the feed pipe has a slot that matches the locking block. The filter element is located inside the housing and is detachably connected to the housing. The housing has an air outlet on the side away from the feed pipe, and the flow sensor is located at the air outlet.

[0015] By adopting the above technical solution, the filter element can be effectively replaced through the detachable connection between the box and the feed pipe. The flow sensor can check the air volume at the air outlet. If the flow is too large, it indicates that the filter element is damaged. If the flow is small, it indicates that the storage plate has not flipped properly or the filter element is blocked.

[0016] Optionally, an arc-shaped scraper is provided on the lower side of the baffle. The bending direction of the arc-shaped scraper is the same as the direction of chain movement. An avoidance groove is provided on the side of the substrate near the feeding assembly. A guide ramp for the arc-shaped scraper is provided at the avoidance groove.

[0017] By adopting the above technical solution, when the baffle transports materials, the arc-shaped scraper on the lower side of the baffle scrapes the materials on the substrate, causing them to move along the arc-shaped scraper to the baffle. This can effectively reduce the adhesion of materials with a certain degree of stickiness to the substrate and facilitate the discharge of materials from the conveyor belt. The guide ramp can ensure that the baffle enters the substrate in the correct state.

[0018] Optionally, a protective strip is provided at the end of the arc-shaped scraper, and the protective strip is made of soft material.

[0019] By adopting the above technical solution, the protective strip made of soft material can effectively protect the material and prevent damage to the material when the arc-shaped scraper scrapes the material.

[0020] In summary, this application includes at least one of the following beneficial technical effects of adjustable-pitch particulate conveyor belts:

[0021] 1. When conveying granular materials, the feeding assembly conveys the material to the substrate, the transmission gear drives the chain to rotate, and the material is restricted between two baffles by the guard plate. The operator controls different interval sizes by adjusting the position of the baffles on the chain, thereby controlling the amount of material of different sizes in different intervals, so as to achieve continuous and sustainable supply of granular materials to the equipment and effectively adjust the feeding amount per unit time.

[0022] 2. By spraying compressed air into the feed pipe through the nozzle, a negative pressure is created at the inlet of the feed pipe. This allows particulate matter at the inlet of the feed pipe to be drawn into the feed pipe and discharged to the outlet of the feed pipe, thereby achieving the supply of materials to the substrate.

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] This application discloses an adjustable-pitch particulate conveyor belt.

[0030] Reference Figures 1 to 4 An adjustable-pitch granular conveyor belt includes a frame 1. The frame 1 has a base plate 11 along its length. Protective plates are provided on both sides of the base plate 11 in its width direction. At both ends of the frame 1 along the length of the base plate 11, there are transmission gears 13 and drive motors 12. Chains 14 pass through the transmission gears 13. Several slots 141 are provided on the side of the conveyor belt closest to the base plate 11, with each slot 141 corresponding to one of the chains 14. Baffles 15 are detachably connected to each slot 141. A feeding assembly is provided at one end of the base plate 11, and the feeding assembly includes a material storage component to temporarily block material from entering the base plate 11. When conveying granular material, the feeding assembly conveys the material to the base plate 11. The transmission gears 13 drive the chains 14 to rotate, and the protective plates confine the material between the two baffles 15. The operator controls different interval sizes by adjusting the position of the baffles 15 on the chains 14, thereby controlling the quantity of material of different sizes within different intervals. This achieves a continuous and sustainable supply of granular material to the equipment and effectively adjusts the feeding amount per unit time.

[0031] In this embodiment, the detachable connection method is as follows: The chain 14 is bent to both sides, and then the baffle 15 is removed from the slot 141 and inserted into another slot 141 to complete the adjustment. The installed baffle 15 can rotate within the slot 141. Figure 1 The lower middle baffle 15 faces downwards.

[0032] Because of the low mass of individual particulate materials, pneumatic feeding can effectively convey and transport them, and can also separate mixed fragments and impurities. The feeding assembly includes a feeding pipe 2, the outlet of which is located above the inlet of the substrate 11. A compressed air nozzle 21 is installed inside the feeding pipe 2, pointing towards the outlet of the feeding pipe. An air compressor supplies compressed air to the nozzle 21. By blowing compressed air into the feeding pipe 2 through the nozzle 21, a negative pressure is created at the inlet of the feeding pipe 2. This draws particulate matter from the inlet of the feeding pipe 2 into the feeding pipe 2 and discharges it towards the outlet, thus achieving material supply to the substrate 11.

[0033] To slow down the material's exit speed from the feed pipe 2 and ensure it falls smoothly onto the substrate 11, a filter grid is provided on the upper side of the feed pipe 2. A filter assembly 3 is located above the feed pipe 2 and is detachably connected to it. A baffle curtain 23 is provided on the side of the feed pipe 2 closest to the substrate 11. The baffle curtain 23 guides and restricts the particulate material as it exits the feed pipe 2, allowing it to fall relatively smoothly onto the substrate. The filter grid and filter assembly 3 effectively adsorb dust and impurities from the particulate material, while simultaneously allowing compressed air to be discharged to ensure material supply.

[0034] To achieve intermittent feeding of granular materials, i.e., discharging a fixed weight of material from the feeding pipe at a time, a material storage assembly includes a storage plate 24 and a plate tilting motor 22. The storage plate 24 is rotatably connected to the inner wall of the feeding pipe 2, and the plate tilting motor 22 controls the rotation of the storage plate 24. A pressure sensor 241 is located on the side of the storage plate 24 near the inlet of the feeding pipe 2. If intermittent feeding is required to the baffle 15, the storage plate 24 can be rotated down by the tilting motor. At this time, the material will accumulate at the storage plate 24. When the pressure at the pressure sensor 241 reaches the set value, the storage plate 24 tilts open to continue feeding.

[0035] To facilitate the replacement of the filter cartridge assembly and to detect and inspect blockages within the filter assembly 3 and the feeding pipe, the filter assembly 3 includes a housing 31, a filter element 34, and a flow sensor 33. A locking block is located on the side of the housing 31 closest to the feeding pipe 2, and the feeding pipe 2 has a slot that matches the locking block. The filter element 34 is located inside the housing 31 and is detachably connected to the housing 31. An air outlet 32 ​​is located on the side of the housing away from the feeding pipe 2, and the flow sensor 33 is located at the air outlet 32. The detachable connection between the housing 31 and the feeding pipe 2 allows for effective replacement of the filter element 34. The flow sensor 33 can check the airflow from the air outlet 32; excessive flow indicates a damaged filter element 34, while insufficient flow indicates that the storage plate 24 is not properly rotated or that the filter element 34 is blocked.

[0036] When transporting materials with high viscosity, there is a possibility that the material may stick to the conveying equipment. To minimize this sticking, an arc-shaped scraper 151 is provided on the lower side of the baffle 15. The bending direction of the arc-shaped scraper 151 is the same as the movement direction of the chain 14. A clearance groove is provided on the side of the substrate 11 near the feeding assembly, and a guide ramp 111 for the arc-shaped scraper 151 is provided in the clearance groove. When the baffle 15 transports materials, the arc-shaped scraper 151 on the lower side of the baffle 15 scrapes the material on the substrate 11, causing it to move along the arc-shaped scraper 151 to the baffle 15. This effectively reduces the adhesion of viscous materials to the substrate 11 and facilitates the discharge of materials from the conveyor belt. The guide ramp 111 ensures that the baffle 15 enters the substrate 11 in the correct position. A protective strip 152 made of soft material is provided at the end of the arc-shaped scraper 151. The protective strip 152, made of soft material, can effectively protect the material and prevent it from being damaged when the arc-shaped scraper 151 scrapes the material.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
