Description

Technical Field

[0001] This utility model belongs to the technical field of bulk grain conveying and warehousing devices, specifically relating to an assembled unloader. Background Technology

[0002] The existing belt conveyor with four-way unloading device used in the bulk grain conveying and storage section has a horizontally arranged four-way guide hopper positioned below the upper redirecting roller. This causes the upper redirecting roller to be raised too high, resulting in a large initial velocity of the material during unloading. Taking the 80 model as an example, the excessively high upper redirecting roller leads to: 1. An excessively large belt tilt angle, resulting in a decrease in equipment output. Competitors' products have a belt tilt angle of up to 8°, with a rated output of only 200T / h; 2. An excessively high overall equipment height. Competitors' equipment has a total height of 1756mm, which affects the convenience of process layout; 3. The guide hopper encroaches on the position of the lower redirecting roller, resulting in a large belt wrap angle between the two redirecting rollers, high belt tension on the rollers, large roller bearing specifications, and a short service life. Utility Model Content

[0003] The purpose of this utility model is to provide an assembled unloader to solve the technical problems of reduced output, high cost and inconvenient installation caused by the horizontal arrangement of the four-way guide hopper in existing unloaders.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an assembled unloader, characterized in that it includes: A housing, on which a conveyor belt redirection assembly is provided for redirecting the conveyor belt; A four-way material guiding mechanism is disposed within the housing; the four-way material guiding mechanism is inclined toward the conveyor belt redirection assembly; the four-way material guiding mechanism includes: The guide hopper has an upper feeding channel for receiving material from the conveyor belt redirection assembly; a lower feeding channel is provided in the guide hopper; and discharge channels are provided on both sides of the guide hopper. A guide gate assembly is rotatably mounted on the guide hopper via a rotating shaft located at the bottom intersection of the feeding channel and the discharge channel; the rotation of the guide gate is used to switch the discharge of the discharge channel and the feeding channel. A guide gate drive assembly is disposed on the guide hopper, and the guide gate drive assembly is connected to the guide gate assembly via a connecting rod and a rotating shaft.

[0005] Considering the high initial velocity of the material during throwing, this invention arranges the four-way guiding mechanism at an angle, eliminating the need to place the guide hopper below the upper redirecting roller and reducing the lifting height of the upper redirecting roller. Taking the 80 model as an example, it has the following technical advantages: 1. The belt tilt angle of this utility model product is only 4°, and the tested output reaches 347T / h; 2. The height of this utility model is 1410mm, and the height of the side plate does not exceed the width of the galvanized sheet raw material (1510mm), which reduces the product height and improves the convenience of process layout; 3. The guide hopper does not encroach on the position of the lower redirecting roller, resulting in a smaller belt wrap angle between the two redirecting rollers and less belt tension on the rollers. This allows for a reduction in the size of the roller bearings and an extension of their service life.

Detailed Implementation

[0022] The present invention will be further described below with reference to the figures.

[0023] Example 1 like Figure 8 , Figure 9 , Figure 10 As shown, the assembled unloader 10 includes a housing 100 and a four-way material guiding mechanism 300.

[0024] The housing 100 is a closed structure formed by two side plates 102, a top cover 101, and a chassis groove 103. The housing 100 is preferably made of galvanized sheet. These four parts (especially the side plates) are rarely manufactured using welding processes and can be made of galvanized sheet, thereby improving the corrosion resistance of the equipment housing and meeting the needs of environments such as ports. The galvanized sheet construction of the housing 100 provides better corrosion resistance. An inspection port 105 is provided on the top cover 101. Inspection windows 106 are provided on the side plates 102. Bearing brackets 104 are installed on the side plates 102 for installing conveyor belt redirection bearings. A conveyor belt redirection assembly is provided on the housing 100 for redirecting the conveyor belt 400. The conveyor belt redirection assembly includes an upper redirecting roller 210 and a lower redirecting roller 220. The lower redirecting roller 220 is located below and behind the upper redirecting roller 210. After passing through the upper redirecting roller 210 and the lower redirecting roller 220, the conveyor belt 400 is supported on the transition idler roller 500.

[0025] A four-way material guiding mechanism 300 is provided inside the housing 100; the four-way material guiding mechanism 300 is inclined toward the conveyor belt redirection component.

[0026] like Figure 1-5As shown, the four-way material guiding mechanism includes a material guide hopper 310, a material guide gate assembly 320, and a material guide gate drive assembly 330.

[0027] The guide hopper 310 includes a front side plate 311, a rear side plate 312, two hopper mounting flanges 315, a discharge channel 302, and partitions 316. Hopper mounting flanges 315 are installed at the left and right ends of the front side plate 311 and the rear side plate 312, respectively. A first discharge port 313 and a second discharge port 314 are machined on the two side hopper mounting flanges 315, respectively. Partitions 316 are provided on both sides of the bottom of the guide hopper, and the partitions 316 are inclined downwards from the inside out. A discharge channel 302 is provided between the partitions 316. The side plates corresponding to the partitions 316 and the discharge channel 302 can be an integral structure or a separate structure. A feed channel 301 is provided at the upper part of the guide hopper 310 for receiving material from the conveyor belt redirection assembly; a discharge channel 302 is provided at the lower part of the guide hopper 310. The guide hopper is provided with discharge channels 303 on both sides, that is, the discharge channels 303 are formed between the partition plate 316 and the corresponding front side plate 311 and rear side plate 312. The discharge channels 303 are located on both sides of the unloading channel 302.

[0028] This utility model adopts a modular design. The four-way guide hopper serves as the core structure to withstand the impact of materials. It is fixedly connected to the external structure, with no relative movement and no sealing problem. Furthermore, the guide hopper is made of thick plate welded together, resulting in high structural strength.

[0029] In one embodiment, wear-resistant liners 380 are provided on the front and rear side plates and the upper and lower material channels of the feed hopper 310. The surface of the hopper is covered with wear-resistant material, which can extend the service life of the equipment.

[0030] The guide gate assembly 320 is rotatably mounted on the guide hopper 310 via a rotating shaft located at the bottom intersection of the feeding channel and the discharge channel; the rotation of the guide gate is used to switch the discharge channel and the feeding channel for material discharge.

[0031] The guide gate drive assembly 330 is mounted on the guide hopper 310 and is connected to the guide gate assembly via a connecting rod and a rotating shaft.

[0032] In one embodiment, the guide gate assembly 320 includes a first guide gate 321 and a second guide gate 322 arranged symmetrically, with the first guide gate 321 and the second guide gate 322 arranged in opposite directions of rotation; The guide gate drive assembly 330 includes a first guide gate drive component 331 and a second guide gate drive component 332; The first guide gate drive unit 331 is connected to the first guide gate 321 via the first connecting rod 341 and the first rotating shaft 351; The second guide gate drive unit 332 is connected to the second guide gate 322 via the second connecting rod 342 and the second rotating shaft 352; The first and second rotating shafts are set in opposite directions of rotation.

[0033] Bearings 353 are installed on the front side plate 311 and the rear side plate 312 respectively to support the first rotating shaft 351 and the second rotating shaft 352.

[0034] The first guide gate drive unit 331 and the second guide gate drive unit 332 are preferably cylinders or electric devices.

[0035] The main moving parts of this utility model's guide hopper are two symmetrically arranged guide doors. The guide doors have a simple structure and swing in a fan shape along the rotating axis. As shown in the figure, when the guide doors close to the middle, the material flows out from the discharge channels on both sides, realizing unloading in the middle of the belt conveyor. A first limiting component is set in the middle of the hopper to prevent material from leaking between the two guide doors. When the guide doors open to both sides, the material flows from the middle guide channel to the rear belt conveyor.

[0036] In one embodiment, a first limiting member 361 and a second limiting member 362 are provided inside the feed hopper. The first limiting member is used to limit the angle at which the first guide gate 321 and the second guide gate 322 rotate towards the middle of the feed hopper; the second limiting member is used to limit the angle at which the first guide gate 321 and the second guide gate 322 rotate towards the outside of the feed hopper.

[0037] In one embodiment, the first limiting member 361 is disposed in the feeding channel 311, and the two ends of the first limiting member are respectively disposed on the front side plate and the rear side plate of the guide hopper in the direction of conveyor belt movement. The guide hopper is provided with discharge ports on its left and right sides respectively. The discharge ports on the guide hopper correspond to the discharge ports on the shell and are provided with discharge pipes 80. A second limiting component is provided on the discharge port of the guide hopper.

[0038] The first limiting component 361 is equipped with a wear-resistant liner 380, which can extend the service life of the equipment.

[0039] In one embodiment, flexible guide plates 370 are respectively provided on the left and right sides of the feeding channel. The flexible guide plates are located above the conveyor belt to prevent material from splashing on the conveyor belt. Flexible guide plates are provided at the contact points between the hopper and the belt to prevent material from splashing off the belt. Side baffles are also provided on the upper part of the guide gate to prevent material leakage.

[0040] In one embodiment, wear-resistant liners 380 are provided on the front and rear side plates of the feed hopper, the feed channel, and the first limiting member.

[0041] In one embodiment, the front and rear ends of the first guide gate 321 are respectively provided with sealing elements for sealing the first guide gate and the guide hopper; The front and rear ends of the second guide gate 322 are respectively equipped with sealing elements for sealing the second guide gate and the guide hopper. Sealing material is embedded on both longitudinal sides of the guide gate to achieve a good seal.

[0042] Both the first guide gate 321 and the second guide gate 322 are equipped with wear-resistant liners 380. The surface of the guide gates is covered with wear-resistant liners, resulting in a long service life.

[0043] In one embodiment, the inclination angle of the conveyor belt 400 is 4°; the included angle between the four-way material guiding mechanism 300 and the chassis groove of the housing is 60°.

[0044] In one embodiment, a mechanical limiting assembly 390 is provided on the feed hopper 310 to limit the rotation angle of the first connecting rod 341 or the second connecting rod 342. Specifically, the mechanical limiting assembly 390 includes an upper mechanical limiting member 391 and a lower mechanical limiting member 392. The upper mechanical limiting member 391 cooperates with the second limiting member 362; the lower mechanical limiting member 392 cooperates with the first limiting member 361.

[0045] The first (second) guide gate is equipped with mechanical limit components at both extreme positions, which can cope with the impact of materials. It does not require the drive cylinder (or electric device) to provide additional support force, which is conducive to ensuring the long-term good use of the drive structure.

[0046] Considering the high initial velocity of the material during discharge, the four-way guide hopper is arranged at an angle, eliminating the need to place it below the upper redirecting roller. This avoids raising the upper redirecting roller too high. Taking the 80 model as an example, an excessively high upper redirecting roller would lead to: 1. An excessively large belt tilt angle, resulting in reduced equipment output. Competitors' products have a belt tilt angle of 8°, with a rated output of only 200T / h, while our product of the same model has a belt tilt angle of only 4°, achieving a tested output of 347T / h; 2. Increased overall equipment height. Competitors' equipment has a total height of 1756mm, while ours is 1410mm, with the side plate height not exceeding the width of the galvanized sheet raw material (1510mm); 3. The excessive height affects the convenience of process layout; 4. The guide hopper does not encroach on the lower redirecting roller position, resulting in a smaller belt wrap angle between the two redirecting rollers, less belt tension on the rollers, which is beneficial for reducing the roller bearing specifications and extending service life.

[0047] This utility model adopts a four-way material guiding mechanism, which has fewer moving parts, simple operation, and good reliability. The overall design of this utility model is modular, and the core four-way material guiding mechanism can be directly replaced if damaged, which makes it easy to maintain. There is no relative movement between the four-way material guiding mechanism and the shell, which ensures a good sealing effect.

[0048] Example 2 like Figure 11 , Figure 12 , Figure 13As shown, the inlet conveyor belt includes an assembled unloader 10, a head section 20, a tail section 30, a feed inlet 40, an inclined section 50, a conveying section 60, support legs 70, and a discharge pipe 80.

[0049] The main innovation of this embodiment is the use of an inclined four-way structure as the material channel to receive the ejected material. First, the material is ejected obliquely upward through a small-angle inclined ascent, and the belt is turned by two sets of redirecting rollers. Then, the material is guided by the core inclined four-way structure to achieve the unloading function.

[0050] The above embodiments are only for illustrating the technical features and concept of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made according to the spirit and implementation of this utility model should be covered within the protection scope of this utility model.
