Description

Technical Field

[0001] This utility model relates to the field of plate feeder technology, and more specifically, to an impact-resistant plate feeder. Background Technology

[0002] Plate feeders, as continuous conveying equipment, are widely used in industries such as mining, metallurgy, and building materials, mainly for the transfer and conveying of lumpy and granular materials. They achieve material transfer through the cyclical movement of chain plates, featuring high load-bearing capacity and high conveying efficiency, making them a key piece of equipment in production lines connecting crushing, screening, and other processes.

[0003] However, traditional plate feeders have two major problems in practical applications: First, when materials fall from a height into the feed inlet, they directly impact the chain plate or the inner wall of the equipment. Long-term use can easily lead to wear, deformation or even breakage of parts, reducing the service life of the equipment. Second, the feed inlet position is fixed and cannot be flexibly adjusted according to the material requirements or material characteristics (such as particle size and flow rate) of downstream processes. It has poor adaptability and will affect the continuity of production when the machine needs to be stopped for adjustment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an impact-resistant plate feeder to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An impact-resistant plate feeder includes a conveyor chain plate, a drive unit matched with the conveyor chain plate, a baffle plate mounted on the conveyor chain plate, a material guide structure mounted on the baffle plate, a buffer structure on the inner side of the material guide structure, a guide rail fixed to the top of the baffle plate, a guide structure on the inner side of the baffle plate, and transmission structures on both sides of the material guide structure. The feeder, consisting of the conveyor chain plate, the drive unit, and the baffle plate, achieves the function of adjusting the position of the feed inlet on the baffle plate through the material guide structure and the transmission structure. The feeder achieves the function of feeding buffering through the buffer structure and the guide structure.

[0008] Furthermore, the material guiding structure includes a material guiding bin, an installation edge, a guide rod, a fixed plate, a buffer base plate, and guide wheels. The top periphery of the material guiding bin is integrally provided with an installation edge, and a guide rod is fixedly provided on the outer side of the installation edge. A fixed plate is fixedly provided at the bottom end of the material guiding bin, and a buffer base plate is fixedly provided at the bottom end of the fixed plate. A guide wheel is provided on one side of the buffer base plate, and the guide wheel is installed on the bottom surface of the fixed plate.

[0009] Furthermore, the buffer structure includes a buffer side plate, a damping sleeve rod, a transmission rod, a damping ring, a return spring, and a hinge seat. The buffer side plate is rotatably connected to both sides of the inner wall of the guide hopper. A damping sleeve rod is provided on one side of the buffer side plate. A transmission rod is installed inside the damping sleeve rod. A damping ring is fixed on the transmission rod. The damping ring is slidably connected inside the damping sleeve rod. A return spring is sleeved on the transmission rod. A hinge seat is connected to one end of the transmission rod and one end of the damping sleeve rod. The transmission rod is connected to one side of the buffer side plate through the hinge seat. The damping sleeve rod is connected to the inner wall of the guide hopper through the hinge seat.

[0010] Furthermore, the guide structure includes a fixed base, a placement slot, a buffer airbag, and a one-way valve. The fixed base is fixedly installed on the inner wall of the enclosure partition. The placement slot is installed on the fixed base, and the buffer airbag is installed in the placement slot. One-way valves are connected to both sides of the buffer airbag.

[0011] Furthermore, the transmission structure includes a mounting plate, a guide block, a lifting block, a threaded block, a bidirectional threaded rod, an adjustment knob, a transmission wheel, and a directional groove. A guide block is fixedly provided on one side of the mounting plate, and a guide rod passes through the guide block. A lifting block is slidably connected to the mounting plate, and a threaded block is provided on the lifting block. A bidirectional threaded rod is drivenly connected to the threaded block, and an adjustment knob is fixedly provided at one end of the bidirectional threaded rod. A transmission wheel is connected to the bottom end of the mounting plate, and a directional groove is opened at the bottom end of the mounting plate, which matches the guide rail.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The buffer structure, through the synergistic action of the buffer side plate, damping sleeve, damping ring and return spring, can directly absorb the impact force when the material falls, reduce damage to core components such as the conveyor chain plate and drive device, and extend the service life of the equipment; when the buffer airbag of the guide structure comes into contact with the buffer bottom plate of the material guide structure, it forms a secondary support buffer, further reducing the impact of vibration.

[0014] 2. The transmission structure controls the rotation of the bidirectional threaded rod by adjusting the knob, which drives the lifting block to realize the lifting of the material guide structure. With the help of the guide rail and transmission wheel, the material guide structure can move in a straight line. The feed inlet position can be adjusted without stopping the machine to adapt to different material flow rates, particle sizes and downstream process requirements, thereby improving production continuity.

[0015] 3. The directional groove and guide rail work together to ensure the linear accuracy of the material guiding structure during movement. The wedge design of the lifting block enables the rapid switching between the "fixed-moving" state of the material guiding structure. The inflation state of the buffer airbag is controlled by a one-way valve, which takes into account both support stability and movement flexibility. The overall structure has strong linkage and is simple and efficient to operate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] According to an embodiment of the present invention, an impact-resistant plate feeder is provided.

[0027] Example 1;

[0028] like Figure 1-6 As shown, the impact-resistant plate feeder according to an embodiment of the present invention includes a transmission chain plate 1, a drive device 2 matched to the transmission chain plate 1, a baffle plate 3 installed on the transmission chain plate 1, a material guiding structure 4 installed on the baffle plate 3, a buffer structure 5 provided on the inner side of the material guiding structure 4, a guide rail 6 fixedly installed at the top of the baffle plate 3, a guide structure 7 provided on the inner side of the baffle plate 3, and a transmission structure 8 provided on both sides of the material guiding structure 4. The feeder composed of the transmission chain plate 1, the drive device 2, and the baffle plate 3 realizes the position adjustment function of the feed inlet on the baffle plate 3 through the material guiding structure 4 and the transmission structure 8, and realizes the feeding buffer function through the buffer structure 5 and the guide structure 7.

[0029] The conveyor chain plate 1, as the core conveying component of the feeder, achieves continuous material conveying through matching connection with the drive device 2. The baffle plate 3 is installed on the conveyor chain plate 1, forming a boundary constraint for material conveying and preventing material from scattering during the conveying process. Together, the three components constitute the basic framework of the feeder, providing a mounting carrier for functional components such as the material guiding structure 4 and the buffer structure 5. Through the synergistic effect with the material guiding structure 4 and the transmission structure 8, the feeder has the ability to adjust the feed inlet position. At the same time, the baffle plate 3 provides a fixed foundation for the guide structure 7 and works with the buffer structure 5 to realize the feeding buffer function, forming an integrated operation process of "transmission-baffle-adjustment-buffering".

[0030] The material guiding structure 4 includes a material guiding bin 401, a mounting edge 402, a guide rod 403, a fixing plate 404, a buffer bottom plate 405, and a guide wheel 406. The top periphery of the material guiding bin 401 is integrally provided with the mounting edge 402, and the outer side of the mounting edge 402 is fixedly provided with the guide rod 403. The bottom end of the material guiding bin 401 is fixedly provided with the fixing plate 404, and the bottom end of the fixing plate 404 is fixedly provided with the buffer bottom plate 405. A guide wheel 406 is provided on one side of the buffer bottom plate 405, and the guide wheel 406 is installed on the bottom surface of the fixing plate 404.

[0031] The material guiding structure 4 guides the material through the material guiding bin 401. The mounting edge 402 is used to fix the material guiding bin 401 to the enclosure partition 3. The guide rod 403 cooperates with the guide block 802 of the transmission structure 8 to ensure the stability of the material guiding bin 401 when it moves. The fixing plate 404 connects the material guiding bin 401 to the buffer bottom plate 405. The buffer bottom plate 405 can contact the buffer airbag 703 of the guide structure 7 to form a support buffer when the material guiding bin 401 is fixed. The inner buffer structure 5 and the bottom buffer bottom plate 405 respectively achieve double buffering from the impact of falling material and the support of the material guiding bin, thereby improving the impact resistance of the feeder.

[0032] The buffer structure 5 includes a buffer side plate 501, a damping sleeve rod 502, a transmission rod 503, a damping ring 504, a return spring 505, and a hinge seat 506. The buffer side plate 501 is rotatably connected to both sides of the inner wall of the guide hopper 401. A damping sleeve rod 502 is provided on one side of the buffer side plate 501. A transmission rod 503 is installed inside the damping sleeve rod 502. A damping ring 504 is fixed on the transmission rod 503. The damping ring 504 is slidably connected inside the damping sleeve rod 502. A return spring 505 is sleeved on the transmission rod 503. A hinge seat 506 is connected to one end of the transmission rod 503 and one end of the damping sleeve rod 502. The transmission rod 503 is connected to one side of the buffer side plate 501 through the hinge seat 506. The damping sleeve rod 502 is connected to the inner wall of the guide hopper 401 through the hinge seat 506.

[0033] The buffer structure 5 directly contacts the falling material through the buffer side plate 501. The buffer device is composed of the transmission rod 503, damping ring 504 and return spring 505 in the damping sleeve 502. When the material impacts the buffer side plate 501, the transmission rod 503 slides in the damping sleeve 502, the damping ring 504 consumes the impact energy through friction, and the return spring 505 provides elastic restoring force to reset the buffer side plate 501. The hinge seat 506 connects the buffer side plate 501 and the inner wall of the guide bin 401 respectively, allowing the buffer side plate 501 to rotate around the hinge point to adapt to the impact angle of materials with different particle sizes. This structure and the guide bin 401 of the guide structure 4 form a continuous "introduction-buffering" effect, which effectively reduces the direct impact of materials on the equipment and protects the core components such as the transmission chain plate 1 and the drive device 2.

[0034] The guide structure 7 includes a fixed base 701, a placement groove 702, a buffer airbag 703, and a one-way valve 704. The fixed base 701 is fixedly installed on the inner wall of the enclosure partition 3. The placement groove 702 is installed on the fixed base 701. The buffer airbag 703 is installed in the placement groove 702. The one-way valve 704 is connected to both sides of the buffer airbag 703.

[0035] The guide rail 6 is fixed to the top of the enclosure partition 3 and cooperates with the directional groove 808 of the transmission structure 8 to provide a guiding path for the movement of the guide bin 401. The fixed base 701 of the guide structure 7 is installed on the inner wall of the enclosure partition 3. The buffer airbag 703 in the placement groove 702 is controlled by the one-way valve 704 to control the inflation state. When the guide bin 401 is fixed, the buffer airbag 703 contacts the buffer base plate 405 of the guide structure 4 to form elastic support and prevent the guide bin 401 from shifting due to vibration. When the guide bin 401 needs to be moved, the buffer airbag 703 separates from the buffer base plate 405 to reduce the movement resistance. The two work together with the transmission structure 8 to realize the function switching of the guide bin 401 from "buffer support when fixed to smooth adjustment when moving", which improves the operation flexibility and stability of the feeder.

[0036] The transmission structure 8 includes a mounting plate 801, a guide block 802, a lifting block 803, a threaded block 804, a bidirectional threaded rod 805, an adjustment knob 806, a transmission wheel 807, and a directional groove 808. A guide block 802 is fixedly provided on one side of the mounting plate 801, and a guide rod 403 passes through the guide block 802. The lifting block 803 is slidably connected to the mounting plate 801, and a threaded block 804 is provided on the lifting block 803. The threaded block 804 is drivenly connected to the bidirectional threaded rod 805, and an adjustment knob 806 is fixedly provided at one end of the bidirectional threaded rod 805. The transmission wheel 807 is connected to the bottom end of the mounting plate 801, and a directional groove 808 is provided at the bottom end of the mounting plate 801. The directional groove 808 matches the guide rail 6.

[0037] The lifting block 803 has a wedge-shaped structure and is connected to the bidirectional threaded rod 805 via a threaded block 804. The adjusting knob 806 controls the rotation of the bidirectional threaded rod 805, enabling the two lifting blocks 803 to move towards or away from each other. When the lifting blocks 803 move away from each other, they push the guide bin 401 downward, causing its buffer base plate 405 to contact the buffer airbag 703, thus fixing the guide bin 401. When the lifting blocks 803 move towards each other, they lift the guide bin 401, separating it from the buffer airbag 703. At this time, the transmission wheel 807 assists the guide bin 401 to slide along the guide rail 6, and the directional groove 808 cooperates with the guide rail 6 to ensure that the guide bin 401 moves in a straight line. This structure serves as the core actuator for adjusting the position of the guide bin 401. Through mechanical transmission and linkage with the buffer airbag 703 of the guide structure 7, it achieves the switching between "fixed" and "moving" states, ensuring the convenience and reliability of the feed inlet position adjustment.

[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0039] In summary, with the help of the above-mentioned technical solution of this utility model, the conveyor chain plate 1, the drive device 2, and the enclosure partition plate 3 form the basic plate feeder conveying device. The buffer structure 5 inside the material guiding structure 4 is mainly used to buffer the impact force of falling material during the material introduction process. The buffer side plate 501 of the buffer structure 5, through the buffer device composed of the damping sleeve rod 502, the damping ring 504, and the return spring 505, can buffer the impact force during the material falling process. The guide structure 7, in conjunction with the transmission structure 8, can change the position of the material guiding structure 4. When the material guiding bin 401 is in a fixed state, the two-way threaded rod 805 is adjusted by adjusting the knob 806 to make its two lifting blocks 803 drive towards each other. The lifting block 803 itself is a transmission wedge block. The outward transmission of the lifting block 803 will cause the material guiding bin to... The buffer base plate 405 at the bottom of 401 will contact the buffer airbag 703, thereby enabling the buffer airbag 703 to play a supporting and buffering role. Due to the contact between the buffer airbag 703 and the buffer base plate 405, the translation of the guide bin 401 will be restricted. When the guide bin 401 needs to move, the adjusting knob 806 drives the lifting block 803 with threaded block 804 in the opposite direction through the bidirectional threaded rod 805. The lifting block 803 gradually approaches, thereby lifting the guide bin 401, so that the buffer airbag 703 does not contact the buffer base plate 405. At this time, it is convenient for the guide bin 401 to be driven. The guide bin 401 can be driven by external force with the assistance of the transmission wheel 807 of the transmission structure 8, so that the guide bin 401 can be driven along the direction of the guide rail 6.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
