Description

Technical Field

[0001] The utility model relates to a belt hoist, in particular to a belt hoist capable of deflecting an angle. Background Art

[0002] The current elevator discharge port and feed hopper are on the same plane, and the elevator can only achieve vertical lifting on the same plane. When laying out equipment on site, the feed chute angle is often not good or the discharge hopper angle is too large because the inlet and outlet are on the same plane. It is necessary to increase the height of the elevator to achieve the layout angle, which increases the manufacturing cost and operating cost of the elevator. Especially for bulk material transportation, the elevator is used in large quantities, the site is limited, and the elevators are densely distributed. The inlet and outlet of the elevator are on the same plane, which greatly increases the difficulty of layout.

[0003] In order to solve the above technical problems, a design idea is to horizontally deflect the discharge port of the machine head relative to the feed port of the machine base by a certain angle. However, after the deflection of the machine head, the flexible bucket belt will be separated from the head and tail wheels due to uneven force. That is, because the bucket belt is a flexible body, after the flexible body is twisted, the forces on both sides are different. The wider the belt, the greater the force difference on both sides of the belt. After the bucket belt is subjected to uneven force, it will run to both sides of the head wheel. The greater the force and the faster the speed, the faster it will be separated from the head wheel. In the prior art, although the discharge port is designed The elevator on the same plane as the feed hopper also has a certain anti-deviation structure, such as a patented roller structure for preventing the elevator belt from deviating (Announcement No. CN216510794U). However, it uses the bolt head as a guide. When used in a belt elevator that has deviated at a certain angle, the belt will vibrate greatly when entering the head wheel guide groove during actual operation. The bolt head is not smooth and cannot rotate after being installed on the bucket belt. It is easy to get stuck in the head wheel guide groove and tear the bucket belt. It cannot prevent deviation and cannot adapt to the deflection of the head wheel. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a belt elevator with a deflection angle, which can realize feeding and unloading on non-same vertical planes of the head and base, thereby increasing the flexibility of the process layout, minimizing the height of the elevator and the length of the slide pipe, reducing the initial equipment cost, reducing equipment power, and reducing factory space.

[0005] The utility model provides the following technical solutions:

[0006] A belt elevator with a deflectable angle comprises a machine head, a machine base and a bucket belt sleeved between a head wheel of the machine head and a tail wheel of the machine base for material transmission, wherein the discharge port of the machine head is horizontally deflected by 10-15° relative to the feed port of the machine base, and a circle of guide wheels is provided in the middle of the bucket belt, and the head wheel and the tail wheel are provided with annular guide grooves rollingly fitted on the outside of the guide wheels, so as to generate mechanical pressure to force the bucket belt to run between the head wheel and the tail wheel, so that the elevator can also operate normally after the deflection is realized, and the central axis of the guide wheel is installed on the bucket belt by a threaded screw.

[0007] Preferably, two groups of guide plates are installed on the side where the bucket belt is lifted and on the machine head before the guide wheel engages with the head wheel. The two groups of guide plates are arranged opposite to each other and there is a gap between them for the guide wheel to pass through, so that the guide wheel first enters the guide plate and then engages with the head wheel. The guide plate can help the guide wheel enter the annular guide groove more smoothly.

[0008] Preferably, the guide plate is inclined 4-10° from top to bottom toward the inside of the bucket belt. The inclination of the guide plate can facilitate the entry of the guide wheel and reduce the probability of contact between the guide plate and the bucket belt if the bucket belt shakes. Since the spacing between the two sets of guide plates is larger than the outer diameter of the guide wheel, this guide plate can be used to pre-position the guide wheel before the guide wheel enters the annular guide groove of the head wheel, because the width of the annular guide groove of the head wheel is only 2-5mm larger than the outer diameter of the guide wheel. If there is a guide plate, the guide wheel can enter the guide groove of the head wheel more accurately.

[0009] Preferably, the bolt head of the threaded screw has a large chassis, because if the threaded screw chassis is large, the force-bearing area is also large, so the force per unit area can be reduced, thereby reducing damage to the bucket belt. The guide wheel is made of nylon and has a smooth surface.

[0010] The beneficial effects of the utility model are as follows: the utility model is a deflectable elevator, which can realize the deflection of the machine head discharge port by 10-15 degrees to discharge materials. After the machine head is deflected, the flexible bucket belt will be separated from the head and tail wheels due to uneven force. In the elevator of the utility model, the mechanical pressure can be generated by the meshing of the guide wheel on the bucket belt and the annular guide groove on the head wheel, forcing the bucket belt to run in the middle of the head wheel, so that the elevator can also run normally after the deflection is realized;

[0011] A guide wheel is installed in the middle of the inner ring of the bucket belt and is installed with a threaded screw. The bolt head of the threaded screw is a large chassis, which can reduce damage to the bucket belt. The guide wheel is made of nylon with a smooth surface. The annular guide groove added in the middle of the head wheel allows the guide wheel to engage into the annular guide groove of the head wheel when the head wheel drives the bucket belt to rotate. The elevator rises to one side and a guide plate is added before the guide wheel engages with the head wheel. The inclination of the guide plate can be set to 5°. The 5° design is more reasonable after installation, and the degree can float slightly. Therefore, the guide wheel first enters the guide plate and then engages into the head wheel. The guide plate can assist the guide wheel to enter the guide groove of the head wheel more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1-3As shown, a belt elevator with a deflectable angle, in this embodiment, includes a head 1, a base 2, and a bucket belt 5 sleeved between a head wheel 3 of the head 1 and a tail wheel 4 of the base 2 for material transmission. The discharge port of the head 1 is horizontally deflected by 10-15° relative to the feed port of the base 2. This deflection is determined before installation. According to the determined deflection angle, the round barrel flange is made into a corresponding deflection angle. After the equipment is installed, it is in the direction after deflection, and a circle of guide wheels 6 is provided in the middle of the bucket belt 5. The head wheel 3 and the tail wheel 4 are provided with an annular guide groove 7 that is roll-fitted on the outside of the guide wheel 6. The guide wheel 6 and the annular guide groove 7 are roll-fitted on the outside of the guide wheel 6. The guide groove 7 is rolled and meshed to generate mechanical pressure, forcing the bucket belt to run between the head wheel 3 and the tail wheel 4. After the deflection is achieved, the elevator can also run normally. Since the guide wheel 6 can rotate, it is also easier to enter the guide groove, and the resistance can be reduced, and the energy consumption can be reduced. In the prior art, the bolt head is used as a guide. When it is applied to the belt elevator with a deflection angle, the belt will vibrate greatly when entering the annular guide groove 7 of the head wheel 3. The bolt head 9 is not smooth and cannot be rotated after being installed on the bucket belt. Therefore, it is easy to get stuck in the annular guide groove 7 and tear the bucket belt, so it is impossible to prevent deviation, and it is even more impossible to achieve the deflection of the head wheel 3;

[0019] The utility model is a belt elevator with a deflectable angle, which is mainly used to solve the problems that the inlet and outlet materials are in the same plane, resulting in a bad chute angle and the unloading direction not meeting the requirements. The cooperation between the guide wheel 6 and the annular guide groove 7 on the bucket belt 5 can achieve a better effect.

[0020] The central axis of the guide wheel 6 is installed on the bucket belt 5 through the threaded screw 8. The bolt head 9 of the threaded screw 8 is a large chassis. Because if the chassis of the threaded screw 8 is large, the force-bearing area is also large, so the force per unit area can be reduced, thereby reducing the damage to the bucket belt. The guide wheel 6 is made of nylon and has a smooth surface.

[0021] On the side where the bucket belt 5 is lifted and before the guide wheel 6 engages with the head wheel 3, two groups of guide plates 10 are installed on the head 1. The two groups of guide plates 10 are arranged opposite to each other, and there is a gap between them for the guide wheel 6 to pass through, so that the guide wheel 6 first enters the guide plate 10 and then engages with the head wheel 3. The guide plate 10 can assist the guide wheel 6 to enter the annular guide groove 7 more smoothly.

[0022] The guide plate 10 is inclined 5° from top to bottom toward the inside of the bucket belt 5. The inclination of the guide plate 10 can facilitate the entry of the guide wheel 6 and can reduce the contact probability between the guide plate 10 and the bucket belt if the bucket belt shakes. Since the spacing between the two groups of guide plates 10 is larger than the outer diameter of the guide wheel 6, this guide plate 10 can be used to pre-position the guide wheel 6 before the guide wheel 6 enters the annular guide groove 7 of the head wheel 3, because the width of the annular guide groove 7 of the head wheel 3 is only 2-5mm larger than the outer diameter of the guide wheel 6. If there is a guide plate 10, the guide wheel 6 can enter the guide groove of the head wheel 3 more accurately.

[0023] The working principle of the utility model is as follows: the utility model is a deflectable elevator, which can realize the deflection of the discharge port of the machine head 1 by 10-15° for discharging. After the machine head 1 is deflected, the flexible bucket belt will be separated from the head and tail wheels 4 due to uneven force. In the elevator of the utility model, the mechanical pressure can be generated by the meshing of the guide wheel 6 on the bucket belt and the annular guide groove 7 on the head wheel 3, forcing the bucket belt to run in the middle of the head wheel 3, so that the elevator can also run normally after the deflection; the guide wheel 6 is installed in the middle of the inner ring of the bucket belt, and the guide wheel 6 is installed with a thread screw 8, and the bolt head 9 of the thread screw 8 is a large chassis, It can reduce the damage to the bucket belt. The guide wheel 6 is made of nylon with a smooth surface. The annular guide groove 7 added in the middle of the head wheel 3 allows the guide wheel 6 to engage with the annular guide groove 7 of the head wheel 3 when the head wheel 3 drives the bucket belt to rotate. The elevator rises to one side, and before the guide wheel 6 engages with the head wheel 3, a guide plate 10 is added. The inclination of the guide plate 10 can be set to 5°. The 5° design is more reasonable after installation, and the degree can float slightly. Therefore, the guide wheel 6 first enters the guide plate 10 and then engages with the head wheel 3. The guide plate 10 can assist the guide wheel 6 to enter the guide groove of the head wheel 3 more smoothly.

Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
