Description

Technical Field

[0001] The present invention relates to a tubeless mobile four-way discharging device, belonging to the technical field of material transportation. Background Art

[0002] The discharging device is one of the important components in the field of material transportation. Its function is to change the conveying direction of materials at any time according to the needs of the process. Traditional discharging devices include flap type and mobile type. The flap type structure often has problems such as jamming, while the mobile (or swing type) discharging device effectively solves the jamming problem, but generally has a relatively large structure, including three main parts: an upper fixed hopper, a middle moving hopper, and a lower fixed hopper, which is difficult to arrange in a narrow space. It is generally arranged at the head of the belt conveyor.

[0003] In the prior art, for the discharging device using the moving hopper technology, its moving direction is generally perpendicular to the running direction of the belt. Limited by this technical feature, it occupies a large space and it is very difficult to discharge materials at the middle part of the belt conveyor. For the middle discharging of the belt conveyor, except for using a mobile discharging trolley and a plow discharging device, there are few other structural forms of material distribution devices. The mobile discharging trolley occupies a large space, has a high cost, and has many control facilities. Although the plow discharging device occupies a small area, it has obvious disadvantages such as material leakage and belt damage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to overcome the above-mentioned technical disadvantages and provide a tubeless mobile four-way discharging device with a simple structure, convenient operation, and capable of effectively realizing material distribution in space-limited parts such as the middle of the belt.

[0005] To solve the above technical problem, the technical solution proposed by the present invention is: a tubeless mobile four-way discharging device, including: a first belt, a second belt, and a moving hopper; the discharging end of the first belt is located above the second belt, the moving hopper straddles the second belt and can be driven by a power mechanism to approach or move away from the discharging end of the first belt; there is a gap between the moving hopper and the second belt; the top of the moving hopper has a feed inlet, and the bottom of the moving hopper has two discharge outlets respectively located on both sides of the second belt; when the moving hopper approaches the discharging end of the first belt, the materials on the first belt, along with the running of the first belt, can fall from the discharging end of the first belt into the feed inlet of the moving hopper and then fall out from the discharge outlet of the moving hopper; when the moving hopper moves away from the discharging end of the first belt, the materials on the first belt, along with the running of the first belt, can fall from the discharging end of the first belt onto the second belt.

[0006] A further improvement of the above solution is that: the second belt is an extension part of the first belt after passing through several redirecting wheels.

[0007] A further improvement of the above solution is as follows: a first redirecting wheel is provided at the discharging end of the first belt, and a second redirecting wheel is provided below the first belt; after the first belt passes through the first redirecting wheel and the second redirecting wheel in sequence, the second belt is formed; one end of the second belt is located below the first belt.

[0008] A further improvement of the above solution is as follows: both sides of the movable hopper are provided with wheel sets, and the wheel sets are supported by tracks arranged on both sides of the second belt.

[0009] A further improvement of the above solution is as follows: a funnel is provided below the discharging port of the movable hopper.

[0010] A further improvement of the above solution is as follows: there are two inclined baffles in the middle of the movable hopper, and the baffles extend along the running direction of the second belt.

[0011] A further improvement of the above solution is as follows: a belt cleaner is provided on the movable hopper. When the movable hopper is close to the discharging end of the first belt, the belt cleaner contacts the first belt.

[0012] The tubeless movable four-way discharging device provided by the present invention adopts a tubeless structure and a material distribution movement form in which the movable hopper is consistent with the running direction of the belt conveyor. It reasonably utilizes the limited space on both the left and right sides of the belt conveyor, occupies a small space, and can not only be arranged at the head of the belt conveyor, but also be arranged at the middle of the belt conveyor and other parts with limited space. The two fixed wheels form an "S" - shaped structure, reasonably utilizing the limited space above the belt conveyor, causing the material to form a drop, and the space below can effectively accommodate the movable hopper. The tubeless four-way discharging device has the function of diverting the incoming material, which can not only effectively avoid material blockage, but also reduce the volume of a single discharging pipe, and more effectively and reasonably utilize the space. The empty belt cleaner is movable, realizing two states of working mode and non - working mode, and cleaning the empty belt of the belt conveyor as needed, reducing the wear of the cleaner on the belt.

[0016] Figure 4 It is Figure 1 The three - dimensional structural diagram of Embodiment

[0017] Embodiment: The tubeless mobile four-way discharging device of this embodiment, as Figures 1 to 4 shown, includes: a first belt 1 and a moving hopper 4; there are a first redirecting wheel 2 and a second redirecting wheel 3 below the first belt 1, the first redirecting wheel 2 and the second redirecting wheel 3 are installed on the frame, after the first belt 1 passes through the first redirecting wheel 2 and the second redirecting wheel 3, it continues to extend, for the convenience of description, the belt after the second redirecting wheel 3 is defined as the second belt; the position of the first redirecting wheel 2 is also the discharging position of the first belt.

[0018] The moving hopper 4 straddles the second belt, and there is a certain gap between the two to accommodate the material carried by the second belt to pass through. There are tracks 6 on both sides of the second belt, and the moving hopper 4 has wheel sets 405 and 406 at both ends. Through the cooperation of the wheel sets and the tracks, the moving hopper 4 can move along the extension direction of the second belt. The moving hopper 4 is driven by a moving cylinder 5. The top of the moving hopper 4 is the feed inlet, and inside it is evenly divided into two discharging hoppers 402 and 403, and the two discharging hoppers extend towards both sides of the second belt respectively, straddling the second belt in an "eight" shape; the discharge outlets of the discharging hoppers 402 and 403 are respectively connected to two funnels 701 and 702.

[0019] There are two inclined baffles in the middle of the moving hopper 4, and the baffles extend along the running direction of the second belt, and the two baffles form the first discharging hopper 401. There is also a belt cleaner 406 on the moving hopper 4.

[0020] As Figure 1 shown, the moving cylinder 5 contracts, driving the moving hopper 4 to move to the right until it stops at the limit. The first discharging hopper 401 of the moving hopper 4 is pulled out from the space formed between the first redirecting wheel 2 and the second redirecting wheel 3, and the material transportation direction is as Figure 1 shown by the arrow in: the material enters from the left side of the first belt, runs on the first belt and then falls into the first discharging hopper 401 after reaching the first redirecting wheel 2, and reaches the second belt. The second belt is also the extension of the first belt. As the belt moves, the material moves out of the first discharging hopper 401. In this state, the belt cleaner 406 moves away from the belt at the first redirecting wheel 2 along with the moving hopper 4 and is in a non-cleaning working mode.

[0021] As Figure 2 and Figure 3 shown, the moving cylinder 5 extends, driving the moving hopper 4 to move to the left until it stops at the limit. The first discharging hopper 401 of the moving hopper 4 moves to the space between the first redirecting wheel 2 and the second redirecting wheel 3, and the material transportation direction is as Figure 2 and Figure 3As shown by the arrow in [description]: The material enters from the left side of the first belt 1, runs on the first belt and is discharged after reaching the first redirecting wheel 2. It enters the movable hopper from the top of the movable hopper 4 as the feed inlet, then falls into the discharge hopper 402 and the discharge hopper 403 respectively, and then enters the first funnel 701 and the second funnel 702 respectively and then transfers to the lower process.

[0022] In this state, the belt cleaner 406 contacts the belt at the first redirecting wheel 2 to clean the empty material section of the belt, avoiding the return belt material of the belt 1 and being in the cleaning working mode.

[0023] The present invention is not limited to the above embodiments. All technical solutions formed by equivalent substitution fall within the protection scope required by the present invention.
