DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0029] Example 1: Refer to Figures 1-5The utility model provides a conveying equipment for large angle conveying, including first frame 1, the bottom end of first frame 1 is connected with several support legs 2 along the length direction equidistance, one end of first frame 1 is rotatably connected with head drum 3, the other end of first frame 1 is rotatably connected with tail drum 4, and head drum 3 is connected with tail drum 4 between conveying belt 5, and first frame 1 is connected with the drive motor 6 for driving head drum 3 to rotate, and the upper end of first frame 1 is fixedly connected with second frame 7, and second frame 7 is rotatably connected with two parallelly arranged rotating drums 8, one of rotating drum 8 is connected with the output end of drive motor 6 through belt transmission part 10, and two rotating drums 8 are connected with two symmetrically arranged transmission belts 9, and transmission belt 9 is one of transmission belt, chain or steel wire rope, and several first connecting rods 11 are connected along the length direction equidistance between two transmission belts 9, and the material box 12 is connected on every first connecting rod 11, and the material box 12 is extruded contact with the upper end of conveying belt 5, and the rotating shaft 14 is rotatably connected on first frame 1 below head drum 3, and the first scraper 15 for cleaning conveying belt 5 is connected on rotating shaft 14, and the first scraper 15 is connected first frame 1 through the first spring 16, and the first spring 16 is equipped with several and is distributed along the length direction equidistance of first scraper 15, and the guide hopper 13 is connected on second frame 7 above tail drum 4, and the support frame 17 is fixedly connected on first scraper 15, and the elastic cleaning block 18 is fixedly connected on the upper end of support frame 17, and the elastic cleaning block 18 is extruded contact with conveying belt 5, and the elastic cleaning block 18 is elastic sponge block.

[0030] Working principle:

[0031] Several support legs 2 support and fix first frame 1, make first frame 1 keep certain inclination angle, drive motor 6 starts to drive head drum 3 to rotate, and head drum 3 drives tail drum 4 to rotate through conveying belt 5, and conveying belt 5 is in tension state under the cooperation of head drum 3 and tail drum 4, simultaneously, the output end of drive motor 6 drives rotating drum 8 to rotate through belt transmission part 10, and rotating drum 8 drives transmission belt 9 to rotate, and transmission belt 9 synchronously drives first connecting rod 11 to rotate, and first connecting rod 11 drives material box 12 to rotate, when material box 12 rotates to the below of rotating drum 8, and extruded contact with the upper end of conveying belt 5, at this moment, the middle region of conveying belt 5 is concave downward, and both sides are upturned, and the loading area is formed between material box 12 and conveying belt 5, and material box 12 and conveying belt 5 move synchronously;

[0032] The material is introduced into the guide hopper 13, and the material in the guide hopper 13 falls into the loading area, which limits the material. The limited material moves towards the head roller 3 along the conveying belt 5. When the material moves to the position of the head roller 3, the material box 12 rotates upwards and separates from the conveying belt 5, so that the material falls from the position of the head roller 3. After the material box 12 rotates upwards, it is located above the conveying belt 5, and the material adhered to the surface of the material box 12 falls onto the conveying belt 5 under the action of its own gravity;

[0033] After the conveying belt 5 releases the material from the head roller 3, it continues to rotate to the bottom end of the head roller 3. At this time, the conveying belt 5 is in contact with the first scraper 15, and the first spring 16 provides elastic support for the first scraper 15, so that the two maintain a pressed contact state. When the conveying belt 5 moves, it slides relative to the first scraper 15, thereby scraping off the material adhered to the belt, achieving primary cleaning. The conveying belt 5 after being cleaned by the first scraper 15 continues to contact the elastic cleaning block 18, which performs secondary cleaning on the surface of the belt, significantly improving the cleaning effect.

[0034] During the material conveying process, the conveying belt 5 works in cooperation with the material box 12. After the material is released, the conveying belt 5 separates from the material box 12 and returns to its original position. At this time, the material box 12 is completely separated from the conveying belt 5, so that the belt is completely exposed. The material adhered to the material box 12 automatically falls off under the action of gravity. The exposed conveying belt 5 can be fully cleaned by the first scraper 15. The design of separating the conveying belt 5 from the material box 12 makes the surface of the conveying belt 5 free from obstruction, which facilitates cleaning operation and improves the maintainability of the entire conveying equipment.

[0035] In example 2, when the material box 12 rotates to the bottom end of the rotating roller 8 and is pressed against the upper end of the conveying belt 5, the material is easily adhered to the contact surface between the material box 12 and the conveying belt 5. With continuous feeding, the material adhered to the contact surface between the material box 12 and the conveying belt 5 gradually increases, thereby affecting the cooperation between the material box 12 and the conveying belt 5 in limiting and conveying the material. Referring to Figures 6-7, as another preferred embodiment of the present application, differs from embodiment 1 in that the second rack 7 is connected with a smoothing mechanism 19 for improving the conveying effect of the material box 12, the smoothing mechanism 19 comprises two parallel fixed seats 191, both of which are fixedly connected to the second rack 7, each fixed seat 191 is slidably connected with a first movable plate 192, one end of the two first movable plates 192 is fixedly connected with the same second scraper 193, the second scraper 193 is inclined downward towards the material box 12, the second scraper 193 is in contact with the material box 12, the bottom end of the second scraper 193 is fixedly connected with a baffle 194 on both sides, one side of each baffle 194 is in contact with the outer wall of the material box 12, the other end of the two first movable plates 192 is fixedly connected with the same first connecting plate 195, the upper end of the first connecting plate 195 is connected with a second spring 196, one end of the second spring 196 is fixedly connected to the second rack 7.

[0036] Working principle:

[0038] In the process of moving the material box 12, relative sliding occurs with the second scraper 193, the second scraper 193 scrapes the material on the contact surface of the material box 12 and the conveying belt 5, keeps the contact surface clean, so as to ensure that the cooperation between the material box 12 and the conveying belt 5 can stably limit and convey the material;

[0039] In addition, in the process of scraping, the baffle 194 limits the scraped material to fall into the inside of the material box 12, avoiding the material falling on the transmission belt 9, so as to not affect the normal operation of the transmission belt 9 driving the rotating drum 8.

[0040] In the process of scraping the contact surface of the material box 12 and the conveying belt 5 by the second scraper 193, the scraped material is easy to accumulate between the second scraper 193 and the baffle 194, as the material continues to increase, the material accumulated between the second scraper 193 and the baffle 194 pushes the second scraper 193 upward, so that a gap is generated between the second scraper 193 and the material box 12, thereby reducing the cleaning effect of the second scraper 193 on the material box 12, referring to Figures 7-9, as another preferred embodiment of the present application, differs from example 2 in that the first movable plate 192 is connected with an anti-blocking mechanism 20 for preventing material accumulation between the baffle 194 and the second scraper 193, the anti-blocking mechanism 20 comprises two symmetrically arranged guide plates 201, each of which is slidingly inserted into the corresponding first movable plate 192, one end of each guide plate 201 is fixedly connected with a second movable plate 202, each second movable plate 202 is fixedly connected with a third spring 203, one end of each third spring 203 is fixedly connected to the corresponding first movable plate 192, one end of each second movable plate 202 is fixedly connected with a push plate 204, one side of each push plate 204 passes through the corresponding baffle 194, a second connecting plate 205 is fixedly connected between the two first movable plates 192, the second connecting plate 205 is slidingly connected with two parallel guide rods 206, the bottom ends of the two guide rods 206 are fixedly connected with a third movable plate 207, the upper end of the third movable plate 207 is fixedly connected with a third connecting plate 208, the two sides of the third connecting plate 208 are fixedly connected with steel ropes 209, one end of each steel rope 209 is fixedly connected to the corresponding second movable plate 202, the upper ends of the second connecting plate 205 are fixedly connected with second connecting rods 2010 on both sides, one end of each second connecting rod 2010 is connected with a guide wheel 2011, each guide wheel 2011 is in contact with the upper end of the corresponding steel rope 209, the two sides of each second connecting rod 2010 are fixedly connected with a fixed plate 2012, one end of each fixed plate 2012 is fixedly connected with a limiting ring 2013, the steel rope 209 passes through the limiting ring 2013, and the guide wheel 2011 and the limiting ring 2013 are on the same straight line.

[0041] Working principle:

[0042] During the upward rotation of the material box 12 separated from the conveying belt 5, the third movable plate 207 is pushed to move upward, and the third movable plate 207 moves stably under the guidance of the second connecting rod 2010 and drives the third connecting plate 208 to move upward, the third connecting plate 208 pulls the steel rope 209 after moving upward, the steel rope 209 pulls the second movable plate 202 horizontally after being guided by the guide wheel 2011, so that the two second movable plates 202 move towards each other, the fixed plate 2012 fixes the limiting ring 2013, and the limiting ring 2013 limits the steel rope 209 to avoid separation of the steel rope 209 and the guide wheel 2011;

[0043] The second movable plate 202 moves smoothly under the guidance of the guide plate 201, the two second movable plates 202 move towards each other and pull the third spring 203, the third spring 203 generates elastic force after being stretched, the two second movable plates 202 move towards each other and drive the push plate 204 to move, the push plate 204 gradually extends into the second scraper 193 and the baffle 194, and the accumulated material between the two is pushed to fall into the material box 12, so that the material accumulated between the second scraper 193 and the baffle 194 can be avoided, so that the second scraper 193 will not be pushed to move upwards, the extrusion strength of the second scraper 193 on the contact surface between the material box 12 and the conveying belt 5 can be maintained, and the cleaning effect can be maintained.

[0044] When the material box 12 is separated from the third movable plate 207, the third movable plate 207 moves downwards under the action of gravity and is reset, and the elastic force of the third spring 203 drives the second movable plate 202 to reset, the second movable plate 202 drives the push plate 204 to reset, in the process that the material box 12 is continuously driven by the conveying belt 5 to rotate upwards, the material box 12 continuously drives the third movable plate 207, so that the push plate 204 continuously pushes the material accumulated between the second scraper 193 and the baffle 194 forward, and the material accumulated between the second scraper 193 and the baffle 194 is avoided.
