Description

Technical Field

[0001] This application relates to the field of aggregate conveying technology, and more specifically, to an aggregate bin unloading device for uniformly and quantitatively conveying aggregates. Background Technology

[0002] In fields such as concrete production, building material processing, and road construction, the storage and quantitative conveying of aggregates (such as sand, gravel, and crushed stone) are core technological processes. As a key device connecting storage and conveying, the performance of aggregate bin feeding equipment directly affects production efficiency, material proportioning accuracy, and equipment operational stability.

[0003] In related technologies, to prevent aggregates from continuing to fall onto the ground and causing cleaning difficulties when the conveyor belt stops due to malfunction, a patent with publication number CN221659682U provides a sand and gravel aggregate feeding hopper. This device is designed with a feeding hopper that acts as a receiving and buffering device, and evenly feeds the material onto the aggregate conveyor belt, solving the problem of material splashing when the aggregate bin is discharging. A rubber buffer pad is installed on the inner wall slope of the feeding hopper, which buffers and protects the inner wall of the feeding hopper, solving the problem of material wear on the inner wall of the feeding hopper. Moreover, a baffle plate and a drive mechanism are installed at the discharge port at the bottom of the feeding hopper. The drive mechanism can automatically open and close the feeding hopper. In the event of equipment failure, the discharge port of the feeding hopper can be closed in time to prevent material from scattering everywhere.

[0004] Although the existing technical solutions mentioned above can achieve the effect of closing the hopper in case of equipment failure to prevent materials from scattering everywhere by automatically switching the hopper on and off through the drive mechanism, the hopper is used to connect the aggregate bin and the aggregate conveyor belt. It is impossible to detect the amount of aggregate received when receiving aggregate, which makes it difficult to control the amount of aggregate discharged, affecting the subsequent mixing ratio of aggregate, and thus has the defect of not being able to uniformly and quantitatively convey aggregate during discharge.

[0005] In view of this, we propose an aggregate bin unloading device for uniformly and quantitatively conveying aggregates. Utility Model Content

[0006] The purpose of this application is to provide an aggregate bin feeding device for uniformly and quantitatively conveying aggregates, which can effectively solve the problem in the prior art that the aggregates cannot be uniformly and quantitatively conveyed during feeding.

[0007] This application provides an aggregate bin unloading device for uniformly and quantitatively conveying aggregates, comprising:

[0010] The receiving hopper, located inside the rotating assembly, is used to quantitatively receive aggregate output from the aggregate bin;

[0011] An aggregate conveyor belt is used to receive the aggregate poured out of the receiving bucket. The aggregate conveyor belt is located inside the load-bearing frame and below the receiving bucket. The aggregate conveyor belt is driven by an external force to intermittently convey aggregate.

[0012] A guide plate, fixedly installed on one side of the load-bearing frame, is used to transfer the aggregate poured from the receiving bucket to the top of the aggregate conveyor belt.

[0013] As an optional solution to the technical solution of this application, the rotating assembly includes two side plates, which are respectively located on both sides of the receiving hopper. End plates are fixedly provided at both ends of the side plates, and support shafts are fixedly provided on the outer sides of the end plates.

Assembly holes are provided on the inner side of each side plate, and the side plates are fixedly connected to the end plates by bolts A.

[0020] As an optional solution to the technical solution of this application, a plurality of conveying rollers are provided on the inner side of the aggregate conveyor belt. The conveying rollers are rotatably disposed between two bearing plates. The two bearing plates are fixedly connected to the load-bearing frame.

[0022] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0023] (1) This application uses a receiving bucket to quantitatively detect the aggregate output from the aggregate bin, and then uses a rotating component to drive the receiving bucket to flip and pour the aggregate onto the top of the aggregate conveyor belt for conveying. Therefore, it effectively solves the problem of the aggregate not being able to be conveyed evenly and quantitatively when the aggregate is unloaded, and thus achieves the effect of conveying the aggregate inside the aggregate bin evenly and quantitatively.

[0024] (2) This application guides the aggregate by setting a guide plate on the outside of the load-bearing frame, so that the aggregate poured out of the receiving bucket can be dispersed and eventually distributed along the length of the aggregate conveyor belt, preventing the aggregate from accumulating at a certain position on the top of the aggregate conveyor belt and falling when the receiving bucket is poured out.

[0025] (3) This application uses a rotating assembly between the bearing seats to drive the receiving bucket to rotate for feeding. When the aggregate conveyor belt fails, the operation of the rotating assembly is stopped, so that the receiving bucket remains in the receiving state, preventing the receiving bucket from continuing to feed when the aggregate conveyor belt stops running and causing the aggregate to scatter.

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Reference Figures 1-4 This application discloses an aggregate bin unloading device for uniformly and quantitatively conveying aggregates, including a support frame 1, a rotating assembly 2, a receiving bin 3, an aggregate conveyor belt 4, and a guide plate 5. Bearing seats 11 are fixedly installed on both sides of the top of the support frame 1. The rotating assembly 2 is driven by external force and is installed between the bearing seats 11 on both sides. The receiving bin 3 is installed inside the rotating assembly 2 and is used to quantitatively receive the aggregates output from the aggregate bin. The aggregate conveyor belt 4 is used to receive the aggregates poured out by the receiving bin 3. The aggregate conveyor belt 4 is installed inside the support frame 1 and below the receiving bin 3. The aggregate conveyor belt 4 is driven by external force to intermittently convey aggregates. The guide plate 5 is fixedly installed on one side of the support frame 1 and is used to transfer the aggregates poured out by the receiving bin 3 to the top of the aggregate conveyor belt 4. Specifically, a fixing plate 32 is fixedly installed at the bottom of the receiving hopper 3, and weighing sensors 33 are symmetrically arranged on the top of the fixing plate 32. A weighing plate 34 is fixedly installed on the top of the weighing sensors 33. The weighing plate 34 is clearance-fitted to the inner side of the receiving hopper 3, and a rubber ring 36 is fixedly installed on the top of the weighing plate 34. The top edge of the rubber ring 36 is interference-fitted with the inner side of the receiving hopper 3. The fixing plate 32 is fixedly connected to the bottom of the receiving hopper 3 by bolt B35, and the rubber ring 36 is fixedly connected to the top of the weighing plate 34 by bolt C37.

[0038] When receiving hopper 3 receives aggregate from the aggregate bin, the aggregate falls onto the top of weighing plate 34. The weight of the aggregate is detected by the weighing sensor 33 at the bottom of weighing plate 34, thus detecting the amount of aggregate output from the aggregate bin. When the required amount is reached, rotating assembly 2 drives receiving hopper 3 to rotate, causing it to flip and dump the aggregate inside. During the flipping process, the aggregate falls onto the top of aggregate conveyor belt 4 under the action of guide plate 5. When receiving hopper 3 has flipped 180° and completely dumped the aggregate, aggregate conveyor belt 4 is driven by external force to transport the aggregate forward. Subsequently, rotating assembly 2 drives receiving hopper 3 to reset and continue receiving aggregate, thereby achieving uniform aggregate distribution. The quantitative conveying effect is as follows: When the aggregate enters the receiving hopper 3, the rubber ring 36 prevents the aggregate from getting stuck in the assembly gap between the receiving hopper 3 and the weighing plate 34, so as to ensure that the weighing plate 34 can transmit the pressure to the top of the weighing sensor 33 for detection when it is subjected to the pressure of the aggregate. The rubber ring 36 is installed on the top of the weighing plate 34 by bolt C37, so as to facilitate replacement when damaged. Under the action of the guide plate 5, the aggregate poured out of the receiving hopper 3 is dispersed, preventing the aggregate inside the receiving hopper 3 from accumulating in the same position when poured out and scattering on both sides of the aggregate conveyor belt 4, which is conducive to the distribution of aggregate along the length direction of the aggregate conveyor belt 4.

[0039] Reference Figure 2 and Figure 3 The rotating assembly 2 includes two side plates 21, which are located on both sides of the receiving hopper 3. End plates 22 are fixedly mounted at both ends of each side plate 21, and support shafts 23 are fixedly mounted on the outer sides of each end plate 22. The support shafts 23 are rotatably mounted inside the bearing seat 11 and are driven to reciprocate by external force. Gears 24 are fixedly mounted on the outer sides of each support shaft 23, and toothed plates 25 are meshed at the bottom of each gear 24. The toothed plates 25 are slidably mounted on the top of the slide rail 26 and are fixedly connected to the driving end of the hydraulic push rod 27. The slide rail 26 and the hydraulic push rod 27 are both fixedly mounted on the top of the support plate 12, which is fixedly mounted on the outer side of the bearing seat 11.

[0040] When the receiving hopper 3 receives a certain amount of aggregate, the hydraulic push rod 27 drives the toothed plate 25 to slide on the top of the slide rail 26, causing the toothed plate 25 to drive the gear 24 to rotate. The gear 24 then drives the support shaft 23 to rotate inside the bearing seat 11, causing the support shaft 23 to drive the receiving hopper 3 between the two side plates 21 to rotate through the end plate 22, thus achieving the effect of automatic material feeding. After completing one tilting action, the side plate 21 is reversed under the drive of the hydraulic push rod 27, thereby causing the receiving hopper 3 to automatically flip and reset.

[0041] Reference Figure 2 and Figure 3Several receiving bins 3 are arranged between the two side plates 21, and the receiving bins 3 are corresponding to several aggregate bins. The inner side of each side plate 21 is provided with an assembly hole 28, and the side plate 21 is fixedly connected to the end plate 22 by bolts A29. Among them, the outer side of the receiving bin 3 is fixedly provided with an mounting block 31 corresponding to the assembly hole 28. Several conveying rollers 41 are arranged inside the aggregate conveyor belt 4. The conveying rollers 41 are rotatably arranged between two bearing plates 42. The two bearing plates 42 are fixedly connected to the load-bearing frame 1. The several conveying rollers 41 are driven by external force to rotate synchronously in the same direction. Among them, the guide plate 5 is located above the bearing plate 42, and baffles 51 are fixedly provided on both sides of the guide plate 5. The baffles 51 are fixedly connected to the bearing seat 11.

[0042] Several receiving buckets 3 are set between the two side plates 21. The receiving buckets 3 are connected to the mounting holes 28 on the inner side of the side plates 21 by the mounting blocks 31 on the outer side, which facilitates the assembly of the receiving buckets 3 and the side plates 21. Finally, the end plate 22 is fixed to the outer side of the side plates 21 by bolts A29 to achieve fastening, so as to facilitate the disassembly and maintenance of the receiving buckets 3. Several receiving buckets 3 can receive aggregate from multiple aggregate bins and weigh them individually. When several receiving buckets 3 are tilted at the same time, the aggregate is dispersed along the guide plate 5, so that the aggregate is distributed along the length of the aggregate conveyor belt 4, preventing the aggregate from accumulating and scattering. Finally, under the drive of external force, the conveying rollers 41 located between the bearing plates 42 on both sides rotate synchronously and in the same direction, so that the conveying rollers 41 drive the aggregate conveyor belt 4 to convey the aggregate received at the top forward. The conveying rollers 41 can be driven by a motor as a power source, which works with a sprocket and chain mechanism to achieve synchronous and unidirectional rotation. Since the motor, sprocket and chain are existing technologies, they will not be described in detail here.

[0043] In summary, the aggregate bin unloading device for uniformly and quantitatively conveying aggregate disclosed in this application, during use, involves the aggregate inside the aggregate bin being conveyed into the receiving hopper 3 by a conveyor (such as a screw conveyor, conveyor belt, etc.). When the receiving hopper 3 receives the aggregate output from the aggregate bin, the aggregate falls onto the top of the weighing plate 34. The rubber ring 36 prevents the aggregate from getting stuck in the assembly gap between the receiving hopper 3 and the weighing plate 34, ensuring that the weighing plate 34 can transmit pressure to the top of the weighing sensor 33 for detection when subjected to the pressure of the aggregate. The weighing sensor 33 at the bottom of the weighing plate 34 detects the weight of the aggregate to detect the amount of aggregate output from the aggregate bin. When the required amount is reached, the hydraulic push rod 27 drives the toothed plate 25 to slide along the slide rail. 26. The top slides, causing the toothed plate 25 to drive the gear 24 to rotate. The gear 24 drives the support shaft 23 to rotate inside the bearing seat 11. The support shaft 23 drives the receiving bucket 3 between the two side plates 21 to rotate through the end plate 22. The receiving bucket 3 flips over and pours out the aggregate inside. During the flipping process, the aggregate will fall on the top of the aggregate conveyor belt 4 under the action of the guide plate 5. When the receiving bucket 3 flips 180° and completely pours out the aggregate, under the drive of external force, the conveying roller 41 located between the two bearing plates 42 rotates synchronously and in the same direction, causing the conveying roller 41 to drive the aggregate conveyor belt 4 to convey the aggregate received at the top forward. After completing one tilting action, the side plate 21 is reversed under the drive of the hydraulic push rod 27, thereby driving the receiving bucket 3 to automatically flip and reset.
