Description

Technical Field

[0001] This invention belongs to the field of continuous conveying technology for bulk materials, and specifically relates to a compact receiving and assembling structure for a press belt conveyor. Background Technology

[0002] Press-belt conveyors utilize a carrier belt and a cover belt to clamp materials and achieve continuous conveying at large angles. Materials typically enter the receiving section's guide chute first and are accelerated within it to match the conveyor belt's speed. After leaving the guide chute, the material enters the merging section, where the cover belt gradually descends under gravity to adhere to the material and carrier belt, completing the merging process. The independent arrangement of the receiving and merging sections results in a long tail section for the press-belt conveyor, occupying a large space and hindering investment control. It also limits the application of press-belt conveyors in situations with limited receiving space. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a compact receiving and belt-gathering structure for a press belt conveyor.

[0004] The technical solution adopted in this invention is: a compact structure for receiving and binding the conveyor belt in a belt press conveyor. Its key technical features include a guide trough body composed of a rear baffle, a right baffle, and a left baffle. The rear baffle faces the tail end of the conveyor, and the opening of the guide trough body faces the head end. The guide trough body is fixed above the receiving point of the carrying belt by a guide trough bracket connected between the left or right baffle and the conveyor frame. A cover belt redirecting roller is positioned above the guide trough body and between it and the rear baffle. Space is provided for material transfer into the main body of the guide trough. A safe distance is left between the lowest edge of the cover belt redirecting roller and the highest edge of the guide trough main body to prevent the cover belt from rubbing against the guide trough main body. The cover belt idler roller group is arranged on the upper edge of the guide trough main body, and the upper edge of the idler roller is higher than the upper edge of the guide trough main body to avoid the cover belt rubbing against the guide trough main body when running along the upper edge of the guide trough main body. After passing around the cover belt redirecting roller, the cover belt moves along the upper edge of the guide trough main body and gradually approaches the material and the carrier belt under the support and guidance of the cover belt idler roller group, and finally adheres to and covers the material and the carrier belt.

[0005] In the above scheme, a buffer device is installed under the bearing belt at the material receiving point to buffer the impact of materials falling from a height on the bearing belt.

[0006] In the above scheme, the buffer device adopts a buffer bed or a group of buffer rollers.

[0007] In the above scheme, the upper part of the main body of the guide trough is provided with guide trough crossbeams arranged at intervals below the covering strip, and the guide trough crossbeams are respectively connected to the right baffle and the left baffle of the guide trough.

[0008] In the above scheme, the guide trough crossbeam is connected to the guide trough support.

[0009] In the above scheme, a material adjustment and centering cable is installed inside the main body of the guide chute in the middle section of the covered closed section. The two ends of the material adjustment and centering cable are symmetrically fixed to the right baffle and the left baffle of the guide chute, respectively. The middle part of the material adjustment and centering cable is in a natural suspended state to achieve centering of the material passing below.

[0010] In the above scheme, a material adjustment and centering cable is installed inside the main body of the guide chute in the middle section of the covered closed section. The two connecting ends of the material adjustment and centering cable are symmetrically located on the left and right sides of the guide chute crossbeam. The centering cable is in a natural suspended state in the middle to achieve centering of the material passing below.

[0011] In the above scheme, the material adjustment centering cable uses flexible materials such as iron chain or steel wire rope.

[0012] In the above scheme, the lower edges of the left and right baffles of the guide chute are sealed to the bearing belt by a flexible wear-resistant material.

[0013] The beneficial effects of this invention are as follows: The compact receiving and merging structure for a press belt conveyor includes a guide trough body fixed above the receiving point of the carrier belt, formed by a guide trough rear baffle, a guide trough right baffle, and a guide trough left baffle. A cover belt covers the guide trough, achieving closure of the upper part of the open guide trough and reducing dust pollution when the material moves within the guide trough. A centering adjustment cable is installed inside the guide trough to effectively correct the off-center loading of the material. After passing around the cover belt redirecting roller, the cover belt moves along the upper edge of the guide trough body and gradually approaches the material and carrier belt under the support and guidance of the cover belt idler group, finally adhering to and covering the material and carrier belt. The acceleration section of the receiving section guide trough and the merging section are overlapped, significantly shortening the tail length of the press belt conveyor, saving tail space, reducing construction investment, and making it easier to apply the press belt conveyor to mobile equipment.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figures 1-4 The present invention will be further described in detail below with reference to specific embodiments.

[0021] Example 1:

[0022] The compact receiving and assembling structure for the press belt conveyor used in this embodiment includes a rear baffle 3 of the guide chute, a right baffle 4 of the guide chute, a left baffle 5 of the guide chute, a cover belt idler group 7, a buffer device 8, a conveyor frame 9, a cover belt redirecting roller 10, a guide chute crossbeam 11, a guide chute support 12, and a material adjustment and centering cable 13. The guide trough body 100 is formed by the rear baffle 3, the right baffle 4, and the left baffle 5 of the guide trough. One end of the guide trough bracket 12 is connected to the left baffle 5 or the right baffle 4 of the guide trough, and the other end is connected to the conveyor frame 9. The guide trough body 100 is fixed above the receiving point of the carrying belt 1, ensuring that the rear baffle 3 of the guide trough faces the tail of the machine and the opening of the guide trough body 100 faces the head of the machine. The lower edges of the left baffle 5 and the right baffle 4 of the guide trough are sealed to the carrying belt 1 by the wear-resistant sealing strips on the left baffle 5 and the right baffle 4 of the guide trough. The cover belt redirecting roller 10 is located on the upper part of the guide chute body 100, about 2 meters away from the rear baffle 3 of the guide chute. This distance is designed to ensure that the material can be smoothly transferred into the guide chute body 100 without interference from the upstream transfer equipment and the material. The lowermost edge of the cover belt redirecting roller 10 is left with a distance of about 20 to 50 mm from the uppermost edge of the guide chute body 100. This distance is designed to ensure that the cover belt 2 does not rub against the guide chute body 100 when passing between the cover belt redirecting roller 10 and the guide chute body 100. Several cover belt idler groups 7 are arranged along the upper edge of the main body 100 of the guide chute. The upper edge of the idler group 7 is slightly higher than the upper edge of the main body 100 of the guide chute, ensuring that the cover belt 2 does not rub against the main body 100 of the guide chute when running along the upper edge of the guide chute. After passing the cover belt redirecting roller 10, the cover belt 2 enters the converging section. The cover belt 2 moves along the upper edge of the guide chute 100 and gradually approaches the material and the carrier belt 1 under the support and guidance of the cover belt idler group 7, and finally adheres to and covers the material and the carrier belt 1. A buffer device 8 is set under the carrier belt 1 at the receiving point to buffer the impact generated when the material falls from a height onto the carrier belt 1. The buffer device 8 adopts a group of buffer beds or buffer idler groups. Except at the receiving point, the carrier belt 1 is supported by several groups of carrier idler groups 6 installed on the conveyor frame 9. Several guide beams 11 are installed below the covering strip on the upper part of the guide chute body 100. The guide beams 11 are spaced about 1.5 to 2 meters apart and are connected to the right baffle 4 and the left baffle 5 of the guide chute, respectively, to provide lateral reinforcement. The guide beams 11 can also be connected to the guide chute support 12. A material adjustment and centering cable 13 is installed inside the guide chute body 100 in the middle section of the covered and enclosed section of the covering strip 2. The adjustment and centering cable 13 is made of flexible materials such as iron chains or steel wire ropes. One end of the adjustment and centering cable 13 is fixedly connected to the right baffle 4 of the guide chute, and the other end is fixedly connected to the left baffle 5 of the guide chute. The two connection points are symmetrically arranged. The middle part of the adjustment and centering cable 13 is in a natural suspension state to achieve centering of the material passing below.

[0023] Example 2:

[0024] The difference between this embodiment and embodiment 1 is that the two ends of the material adjustment centering cable 13 are connected to the guide chute crossbeam 11, and the connection points are symmetrically arranged near the two ends of the guide chute crossbeam 11. The centering cable is in a natural suspension state in the middle to achieve centering of the material passing below it.

[0025] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
