Description

Technical Field

[0001] This invention relates to the field of bulk material conveying technology, and more specifically, to a bulk material universal conveying chute. Background Technology

[0002] In many industrial sectors such as grain, electricity, and coal, chutes are the core conveying equipment for bulk material transfer operations. In actual engineering applications, there are often one-to-many bulk material conveying scenarios where a single upstream chute needs to connect to two or more downstream chutes. For a long time, there has been a lack of simple and efficient adaptation solutions for this type of diversion and conveying requirement.

[0003] Currently, the industry mainly relies on T-junctions and four-way distributors to handle one-to-many bulk material diversion and conveying operations. These distributors often use electro-hydraulic drive structures to achieve diversion and reversal. In actual use, not only is the equipment energy consumption high, which can easily increase the energy costs of production in the long run, but it is also prone to malfunctions such as drive component jamming and failure, which can lead to problems such as blockage in bulk material conveying and poor material discharge, seriously affecting the efficiency of continuous and stable bulk material transfer operations.

[0004] To solve the above-mentioned technical problems, there is an urgent need to provide a chute device with a simple structure, which does not require hydraulic or electric control drive and can meet the needs of multi-directional diversion and conveying. Summary of the Invention

[0005] In view of the above problems, the purpose of this invention is to provide a bulk material universal conveying chute to solve the problems of existing bulk material one-to-many conveying equipment relying on electro-hydraulic drive, high energy consumption, and easy jamming and clogging.

[0006] This invention provides a bulk material universal conveying chute, comprising a bulk material conveying assembly and a mechanical drive assembly, wherein, The bulk material conveying assembly is used to guide bulk materials into multiple receiving troughs at different locations through a swingable buffer structure, thereby realizing one-to-many bulk material diversion and conveying. The mechanical drive component is used to switch and position the material guiding direction by manually controlling the buffer structure of the bulk material conveying component to swing.

[0007] Alternatively, the bulk material conveying assembly may include an upper-level feeding device, a swingable buffer structure disposed below the upper-level feeding device, a guide trough rigidly connected to the buffer structure, and multiple receiving troughs disposed below the guide trough; wherein, An elastic sealing rubber sheet is provided between the buffer structure and the upper-level feeding device.

[0008] Alternatively, the buffer structure can swing within an angle range of ≤30° to achieve multi-directional guiding and conveying of the bulk material.

[0009] Alternatively, the elastic sealing rubber can adaptively deform with the swing of the buffer structure to achieve sealing and dust prevention during rotation.

[0010] Alternatively, the material guide trough can swing synchronously with the buffer structure to guide the bulk material into the corresponding receiving trough.

[0011] Alternatively, the buffer structure can be a circular buffer groove.

[0012] Alternatively, the mechanical drive assembly includes an operating handle hinged to the buffer structure, a pull rod assembly connected to the operating handle, a pull rod length adjustment device disposed on the pull rod assembly, a pull rod fixing bracket for fixing the pull rod assembly, a pull rod redirection device connected to the pull rod assembly, a handle fixing bracket, a slotted positioning tray mounted on the handle fixing bracket, and a handle operating lever disposed on the slotted positioning tray; wherein, The handle operating lever drives the buffer structure and the guide chute to swing synchronously through the pull rod redirection device, the pull rod assembly and the operating handle, so as to divert and transport the bulk material to multiple receiving troughs.

[0013] Alternatively, the tie rod length adjustment device can be used to adjust the length of the tie rod assembly.

[0014] Alternatively, an alternative is to provide three positioning slots on the positioning tray with slots, wherein... The three positioning slots limit and fix the handle operating lever, corresponding to different conveying positions of the guide chute.

[0015] Alternatively, the lever redirection device can be used to change the direction of the power transmission, transferring the force of the handle operating lever to the operating handle, thereby driving the buffer structure to complete the angle deflection.

[0016] As can be seen from the above technical solution, the bulk material universal conveying chute provided by this invention, compared with the prior art, adopts a pure mechanical transmission method, requiring no external energy drive, significantly reducing operating costs, eliminating equipment jamming failures at the source, and ensuring continuous and stable bulk material conveying. This device relies on a circular buffer trough to achieve multi-angle material guidance, easily realizing one-to-three bulk material diversion, ensuring smooth conveying without the risk of material blockage. The equipment can be manually operated for reversing, and with an adjustable tie rod structure, it adapts to various on-site installation environments, making operation simple and labor-saving.

[0027] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] To illustrate the structure of the bulk material universal conveying chute provided by the present invention Figures 1 to 3 The specific structure of the bulk material universal conveying chute is shown from different perspectives in the embodiments. Specifically, Figure 1 A bulk material universal conveying chute structure according to an embodiment of the present invention is shown; Figure 2 A slotted positioning tray structure according to an embodiment of the present invention is shown; Figure 3 The structure of the material guiding device according to an embodiment of the present invention is shown.

[0029] like Figures 1 to 3 As shown in the figure, the bulk material universal conveying chute provided by the present invention includes a bulk material conveying component and a mechanical drive component. The bulk material conveying component is used to guide bulk material into multiple receiving troughs at different positions through a swingable buffer structure to realize one-to-many bulk material diversion and conveying. The mechanical drive component is used to switch and position the material guiding direction by manually controlling the buffer structure of the bulk material conveying component to swing.

[0030] In operation, the bulk material universal conveying chute of this invention conveys bulk materials without consuming additional electrical energy through a mechanical drive component, and no jamming occurs during the conveying process. Specifically, the bulk material conveying component receives upstream bulk materials, achieves multi-directional guiding and conveying of bulk materials through a swingable buffer structure, and prevents dust leakage through sealing components, ultimately guiding the bulk materials into the corresponding receiving trough, completing a one-to-many bulk material diversion and conveying process. The mechanical drive component relies on pure mechanical lever transmission, and the buffer structure of the bulk material conveying component is oscillated by a manually operated component to achieve switching and positioning of the guiding direction, without the need for electro-hydraulic drive, ensuring stable, convenient, and energy-free diversion operation.

[0031] In this invention, the bulk material conveying assembly includes an upper material receiving device 101, a swingable buffer structure disposed below the upper material receiving device 101, a guide trough 103 rigidly connected to the buffer structure, and a plurality of receiving troughs 112 disposed below the guide trough 103; wherein an elastic sealing rubber sheet 104 is provided between the buffer structure and the upper material receiving device 101.

[0032] The upstream material receiving device 101 serves as the upstream inlet for bulk material conveying, receiving and guiding the bulk material into the buffer structure. The buffer structure employs a circular buffer trough 102, which is a swingable core steering component. Its upper part is dynamically sealed to the upstream material receiving device 101 via elastic sealant 104, allowing it to swing freely within an angle range of ≤30°, achieving multi-directional guiding and conveying of the bulk material while ensuring smooth passage and preventing blockages. The elastic sealant 104 is located at the connection between the upper part of the circular buffer trough 102 and the upstream material receiving device 101, adapting to the swing of the buffer trough to achieve a dustproof seal during rotation, preventing dust spillage. The guide trough 103 is rigidly connected to the circular buffer trough 102, swinging synchronously with it to guide the bulk material into the corresponding receiving trough 112. The receiving trough 112 is the downstream bulk material receiving device, corresponding to the A, B, and C working positions of the guide trough 103, receiving the bulk material conveyed by the guide trough.

[0033] In an embodiment of the present invention, the upstream material receiving device 101, the circular buffer trough 102, and the guide trough 103 are combined together to form a material guiding device. The bulk material conveying assembly is responsible for receiving, guiding, sealing, and multi-directional feeding of bulk materials, completing the entire process of bulk material feeding from upstream to downstream distribution and discharge.

[0034] In this invention, the mechanical drive assembly includes an operating handle 105 hinged to a buffer structure, a pull rod assembly connected to the operating handle 105, a pull rod length adjustment device 106 disposed on the pull rod assembly, a pull rod fixing bracket 107 fixing the pull rod assembly, a pull rod redirection device 108 connected to the pull rod assembly, a handle fixing bracket 109, a slotted positioning tray 110 mounted on the handle fixing bracket 109, and a handle operating lever 111 disposed on the slotted positioning tray 110; wherein, the handle operating lever 111 drives the buffer structure and the guide trough 103 to swing synchronously through the pull rod redirection device 108, the pull rod assembly, and the operating handle 105, thereby diverting and conveying the bulk material to multiple receiving troughs 112.

[0035] The handle operating lever 111 is a manually operated component that provides the operating power for the overall reversing action. The pull rod length adjustment device 106 is used to adjust the length of the pull rod assembly to adapt to the installation distance and operating stroke under different working conditions, ensuring the matching of the material guide position.

[0036] The positioning tray 110 with slots is located at the rotation center of the handle operating lever 111. The positioning tray 110 has three positioning slots (A, B, and C), which limit and fix the handle operating lever 111 to different positions, corresponding to different conveying positions of the guide chute. In other words, the three positioning slots are used to lock the handle operating lever 111 in three positions, preventing the guide chute 103 from shifting.

[0037] The lever redirection device 108 is a lever-type transmission mechanism. One end is connected to the handle operating lever 111, and the other end is connected to the operating handle 105 via the lever length adjustment device 106. It converts the rotational motion of the handle operating lever 111 into a linear push-pull motion of the lever. In other words, it changes the direction of the power transmission, transferring the force of the handle operating lever to the operating handle, thereby causing the buffer structure to complete an angular deflection.

[0038] The tie rod length adjustment device 106 is installed on the tie rod assembly, which can adjust the effective length of the tie rod assembly to adapt to the installation distance and operating stroke under different working conditions, and ensure the matching of the material guide position.

[0039] The pull rod fixing bracket 107 and the handle fixing bracket 109 provide fixing points for the pull rod assembly and the handle operating lever 111, respectively, to ensure the stability and operational reliability of the transmission mechanism.

[0040] The operating handle 105 is hinged to the circular buffer groove 102, and receives the pushing and pulling action of the pull rod assembly, which drives the circular buffer groove 102 and the guide groove 103 to swing synchronously, thereby realizing the switching of the guide position.

[0041] In an embodiment of the present invention, the mechanical drive component relies on pure mechanical lever transmission to manually realize the reversing and positioning of the chute, without the need for electric or hydraulic power.

[0042] In practical use, bulk material falls from the upper-level feeding device 101 into the circular buffer trough 102. By operating the handle 111, it is locked in any position (A, B, C) via the positioning tray 110 with a slot. The movement of the handle 111 is converted into linear motion of the pull rod assembly by the pull rod redirection device 108. After adjustment by the pull rod length adjustment device 106, it drives the operating handle 105 to swing the circular buffer trough 102 and the guide trough 103 to the corresponding positions, guiding the bulk material into the corresponding receiving trough 112. The elastic sealing rubber 104 always maintains a sealed state to prevent dust leakage. The circular buffer trough 102 can ensure smooth flow of bulk material at any swing angle without the risk of blockage. The bulk material universal conveying chute is controlled by pure mechanical transmission, without electro-hydraulic drive or additional energy consumption, thus avoiding the problems of jamming and failure of traditional distributors.

[0043] As can be seen from the above technical solution, the bulk material universal conveying chute provided by this invention adopts a purely mechanical transmission structure, eliminating the need for electro-hydraulic drive, saving energy, reducing jamming, and ensuring stable conveying operation. It utilizes a circular buffer trough to achieve one-to-three material conveying, preventing clogging. Reversing can be completed manually, and the adjustable pull rod adapts to various installation scenarios. The equipment has excellent sealing and dustproof performance, accurate and reliable multi-positioning, and a simple structure, making it suitable for bulk material conveying fields such as grain, coal, and power generation.

[0044] The above are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations to these embodiments within the spirit and principles of the present invention, achieved through conventional substitutions or by achieving the same function without departing from the principles and spirit of the present invention, fall within the scope of protection of the present invention.
