Description

Technical Field

[0001] The utility model relates to the technical field of scrapers, and in particular to a scraper for transporting feed. Background Art

[0002] The scraper series of products are widely used in industries and sectors such as metallurgy, building materials, electricity, chemicals, cement, ports, docks, coal, mining, grain and oil, food, and feed. A scraper is a continuous conveying device that uses a moving scraper chain within a closed rectangular cross-section housing to transport bulk materials. Because the scraper chain is completely buried in the material during transportation, it is called a scraper.

[0003] The utility model with publication number CN220722428U discloses a feed powder scraper that is easy to clean, including a support plate, the upper surface of the support plate is fixedly connected to the conveying box, the inner side wall of the conveying box is fixedly inlaid with two sets of bearings, the outer surface of each of the rotating shafts is sleeved with a conveying roller, and the two conveying rollers are connected together by a chain transmission. The outer surface of the chain is fixedly connected with a plurality of scraper bodies arranged at equal distances, and the left side of the support plate is fixedly connected to a driving motor. In the above application document, the material is poured into the conveying box through a feed bin, and then the driving motor is started. The driving motor drives the conveying roller to rotate through the first rotor and the second rotor. The rotating conveying roller drives the scraper body and the chain to move forward, thereby pushing the material forward. When the material is poured from the feed bin into the conveying box, it is easy to accumulate directly below the feed bin, which may affect the transportation of the scraper body. Utility Model Content

[0004] The utility model provides a scraper for transporting feed, which solves the problems raised in the above documents.

[0005] The technical solution of the utility model is as follows: a scraper for transporting feed, comprising a conveying box, the top of the conveying box passes through and is fixedly connected to a feed channel, the bottom of the conveying box is provided with an opening, the inner side wall of the opening is fixedly connected to a guide plate, the front end of the conveying box is fixedly installed with a motor, the internal rotation of the conveying box is connected to a driving shaft and a driven shaft, the output end of the motor is fixedly connected to the front end of the driving shaft, the surface of the driving shaft is fixedly connected to two groups of sprockets A, the surface of the driven shaft is fixedly connected to two groups of sprockets B, chains are provided between the two groups of sprockets A and the two groups of sprockets B, the bottoms of the two groups of chains are fixedly connected to scrapers, the inner side wall of the conveying box A swinging unloading mechanism is provided on the top, and an anti-blocking mechanism is provided on the side of the conveying box; the swinging unloading mechanism includes a rotating gear, a hydraulic warehouse, a connecting frame and a rotating rod, the rotating gear is fixedly connected to the surface of the driving shaft, the hydraulic warehouse passes through and is fixedly connected to the side of the conveying box, the internal piston at one end of the hydraulic warehouse is slidingly connected to the piston rod A, the end of the piston rod A away from the hydraulic warehouse is fixedly connected to the gear rod, and the internal piston at the other end of the hydraulic warehouse is slidingly connected to the piston rod B, the connecting frame is fixedly connected to the inner wall of the conveying box, both ends of the rotating rod are provided with torsion springs, the rotating rod passes through and is rotatably connected to the connecting frame through two sets of torsion springs, and the surface of the rotating rod is fixedly connected to a unloading plate.

[0006] The width of the scraper is equal to the width of the interior of the conveying box, and the number of the scrapers is set to twenty-three groups. When the scraper follows the movement of the chain, it drives the feed at the bottom of the interior of the conveying box to move to the right.

[0007] The blanking plate is initially arranged to be tilted, and is close to the lower side of the feed channel, so that the feed entering from the feed channel falls onto the blanking plate.

[0008] The teeth on the gear rod are matched with the teeth on the rotating gear, and the rotating gear is an incomplete gear. When the rotating gear rotates and its upper teeth are engaged with the teeth on the gear rod, the gear rod will be driven to move rightward.

[0009] The end of the piston rod B away from the hydraulic chamber is hingedly connected to the bottom of the blanking plate. When the piston rod B moves downward, it drives the blanking plate to rotate clockwise by a certain angle.

[0010] The guide plate is initially tilted and located at one end of the conveying box away from the feed channel. The tilted guide plate facilitates the sliding of feed.

[0011] The anti-blocking mechanism includes an air pressure chamber, which passes through and is fixedly connected to the side of the conveying box. An air bag is provided at one end of the air pressure chamber, and a push rod is slidably connected to the internal piston at the other end of the air pressure chamber. The end of the push rod away from the air pressure chamber is fixedly connected to an impact block.

[0012] The airbag is in an expanded state in its initial state. When the expanded airbag is squeezed, the air pressure inside it enters the air pressure chamber and pushes the push rod to move rightward.

[0013] In an initial state, the airbag is close to the bottom of the blanking plate, and the airbag will be squeezed when the blanking plate rotates clockwise.

[0014] In the initial state, the impact block is close to the feed channel, and the material of the impact block is rubber. When the impact block moves to the right, it will hit the feed channel. The impact block made of rubber is elastic and will not cause damage to the feed channel.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] 1. The utility model is provided with a swinging unloading mechanism, so that the motor is turned on to drive the driving shaft to rotate. When the driving shaft rotates and cooperates with the sprocket, chain, driven shaft and other components to drive the scraper to move to transport the feed, the unloading plate is also driven to swing back and forth by the cooperation of the rotating gear, gear rod, hydraulic bin and other components. The unloading plate swings back and forth so that the feed falling from the feed channel will not accumulate at the bottom of the conveying box and affect the scraper transportation.

[0017] 2. The utility model is provided with an anti-blocking mechanism, so that when the feeding plate swings back and forth to feed the feed, the impact block is driven to repeatedly hit the feeding channel through the cooperation of components such as the air bag and the air pressure chamber. The impact block made of rubber material repeatedly hits the feeding channel, causing the feeding channel to vibrate slightly, thereby preventing the feed from being blocked in the feeding channel.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1 to 4As shown, this embodiment proposes a scraper for transporting feed, including a conveying box 1, a feeding channel 2 is passed through and fixedly connected to the top of the conveying box 1, an opening 3 is opened at the bottom of the conveying box 1, and a guide plate 4 is fixedly connected to the inner wall of the opening 3. The guide plate 4 is tilted in the initial state, and the guide plate 4 is located at the end of the conveying box 1 away from the feeding channel 2. The tilted guide plate 4 facilitates the sliding of the feed. A motor 5 is fixedly installed at the front end of the conveying box 1, and a driving shaft 6 and a driven shaft 8 are rotatably connected inside the conveying box 1. The output end of the motor 5 is fixedly connected to the front end of the driving shaft 6, and the surface of the driving shaft 6 is fixedly connected to two sets of chains. Wheel A7, the surface of the driven shaft 8 is fixedly connected with two sets of sprockets B9, and chains 10 are set between the two sets of sprockets A7 and the two sets of sprockets B9. The bottom of the two sets of chains 10 is fixedly connected with a scraper 11. The width of the scraper 11 is equal to the width of the inside of the conveying box 1, and the number of scrapers 11 is set to twenty-three groups. When the scraper 11 moves with the chain 10, it will drive the feed at the bottom of the conveying box 1 to move to the right. A swing unloading mechanism 12 is set on the inner wall of the conveying box 1, and an anti-blocking mechanism 13 is set on the side of the conveying box 1; the swing unloading mechanism 12 includes a rotating gear 121, a hydraulic tank 122, a connecting frame 126 and a rotating rod 127, the rotating gear 121 is fixedly connected to the surface of the driving shaft 6, the hydraulic chamber 122 passes through and is fixedly connected to the side of the conveying box 1, the internal piston at one end of the hydraulic chamber 122 is slidably connected to the piston rod A123, and the end of the piston rod A123 away from the hydraulic chamber 122 is fixedly connected to the gear rod 124, the teeth on the gear rod 124 are adapted to the teeth on the rotating gear 121, and the rotating gear 121 is an incomplete gear. When the rotating gear 121 rotates and its upper teeth mesh with the teeth on the gear rod 124, the gear rod 124 will be driven to move to the left. The internal piston at the other end of the hydraulic chamber 122 is slidably connected to the piston rod B125, connecting The frame 126 is fixedly connected to the inner wall of the conveying box 1, and torsion springs 128 are provided at both ends of the rotating rod 127. The rotating rod 127 passes through and is rotatably connected to the connecting frame 126 through two sets of torsion springs 128. The surface of the rotating rod 127 is fixedly connected to a blanking plate 129. The blanking plate 129 is initially tilted and close to the bottom of the feed channel 2. The feed entering from the feed channel 2 will fall onto the blanking plate 129. The end of the piston rod B125 away from the hydraulic warehouse 122 is hingedly connected to the bottom of the blanking plate 129. When the piston rod B125 moves downward, it will drive the blanking plate 129 to rotate clockwise by a certain angle.

[0028] In this embodiment, the feed is put into the conveying box 1 through the feeding channel 2, and the feed will slide from the discharge plate 129 to the bottom of the conveying box 1. The motor 5 is turned on to drive the driving shaft 6 to rotate. The driving shaft 6 rotates to drive the two sets of sprockets A7 to rotate. The two sets of sprockets A7 rotate and cooperate with the two chains 10 to drive the two sets of sprockets B9 and the driven shaft 8 to rotate, thereby driving the scraper 11 to move. The scraper 11 moves to transport the feed at the bottom of the conveying box 1 to the opening 3 and slides from the guide plate 4. When the driving shaft 6 rotates, it also drives the rotating gear 121 to rotate. When the rotating gear 121 rotates and its upper teeth engage with the teeth on the gear rod 124, it drives the gear rod 124 to move left, and the gear rod 124 moves right to drive the piston rod A12 3 moves to the right, and the rightward movement of the piston rod A123 will drive the piston rod B125 to move downward through the hydraulic pressure in the hydraulic chamber 122. When the piston rod B125 moves downward, it will drive the discharge plate 129 and the rotating rod 127 to rotate clockwise by a certain angle, and the torsion spring 128 is tightened. When the rotating gear 121 rotates to the toothless part and disengages from the gear rod 124, the torsion spring 128 rebounds and drives the discharge plate 129 and the rotating rod 127 to reverse and restore. At this time, the piston rod B125 moves upward and restores, and the piston rod A123 and the gear rod 124 move left and restore, thus forming a cycle. The back and forth swing of the discharge plate 129 prevents the feed falling from the feeding channel 2 from accumulating at the bottom of the conveying box 1 and affecting the conveying of the scraper 11.

[0029] Example 2

[0030] like Figures 1 to 5 As shown, based on the same concept as the above-mentioned embodiment 1, a second embodiment is also proposed. The anti-blocking mechanism 13 includes an air pressure chamber 131. The air pressure chamber 131 passes through and is fixedly connected to the side of the conveying box 1. An air bag 132 is provided at one end of the air pressure chamber 131. The air bag 132 is close to the bottom of the blanking plate 129 in the initial state. When the blanking plate 129 rotates clockwise, it squeezes the air bag 132. The air bag 132 is in an expanded state in the initial state. When the expanded air bag 132 is squeezed, The internal air pressure will enter the air pressure chamber 131 and push the push rod 133 to move to the right. The internal piston at the other end of the air pressure chamber 131 is slidably connected to the push rod 133. The end of the push rod 133 away from the air pressure chamber 131 is fixedly connected to the impact block 134. In the initial state, the impact block 134 is close to the feed channel 2, and the material of the impact block 134 is rubber. When the impact block 134 moves to the right, it will hit the feed channel 2. The rubber impact block 134 is elastic and will not cause damage to the feed channel 2.

[0031] In this embodiment, when the blanking plate 129 swings back and forth to discharge the feed, the blanking plate 129 will squeeze the airbag 132 when it rotates clockwise. The air bag 132 is squeezed and the air pressure inside it will enter the air pressure chamber 131 to push the push rod 133 to move to the right. The push rod 133 moving to the right will drive the impact block 134 to move to the right and hit the feed channel 2. When the blanking plate 129 reverses and returns to leave the airbag 132, the air pressure returns to the airbag 132. At this time, the push rod 133 drives the impact block 134 to move to the left and return. The impact block 134 made of rubber repeatedly hits the feed channel 2, causing the feed channel 2 to vibrate slightly to prevent the feed from being blocked in the feed channel 2.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
