Description

Technical Field

[0001] The utility model relates to the technical field of material transportation equipment, in particular to a material-uniform double-chain conveyor. Background Art

[0002] Chain conveyor is generally the abbreviation of chain conveyor. Chain conveyor is a transmission device with standard chain plate as the bearing surface and motor reducer as the power transmission. Chain conveyor is composed of power device, transmission shaft, roller, tensioning device, sprocket, chain, bearing, lubricant, chain plate, etc. The two main parts that drive the material transportation are: chain, which uses its reciprocating motion to provide traction power; metal plate, which is the carrier during the transportation process.

[0003] The chain conveyor in the prior art generally adopts single chain transportation. The space of the silo arranged above the chain is small. The incoming material falls into the upper surface of the transportation chain before it has time to be evenly loosened and moves forward along the forward direction of the chain. After the material falls into the single chain from the feed port, the speed of the moving process is the same as the transmission speed of the single chain. The speed at which the silo digests the material depends on the transportation speed of the single chain. The speed of the silo digestion cannot be flexibly adjusted without being separated from the transportation speed of the single chain, and the material cannot be evenly distributed during transportation. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a material uniformity double-chain conveyor, which can adjust the moving speed of the two chain plates, utilize the speed difference to uniformly distribute the material, and utilize the height difference between the junction of the first chain plate and the second chain plate to achieve the effect of loosening and uniforming the material by parabolic action.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a uniform material double-chain conveyor, including a chain plate and a driving mechanism, the driving mechanism is used to drive the chain plate to move, the chain plate includes a first chain plate and a second chain plate, the first chain plate is horizontally arranged, the second chain plate includes a second chain plate horizontal section and a second chain plate inclined section that are integrally connected, the first chain plate is arranged on a side close to the second chain plate horizontal section, and the horizontal height of the first chain plate is higher than the horizontal height of the second chain plate horizontal section, a material bin is provided above the first chain plate and the second chain plate horizontal section, a baffle is provided in the material bin, the bottom of the baffle is located at the intersection of the first chain plate and the second chain plate horizontal section, a gap is left between the bottom of the baffle and the upper surface of the first chain plate, and a feed port is provided directly above the first chain plate.

[0006] Furthermore, a material shifting device is provided on the inclined section of the second chain plate, and a material shifting direction of the material shifting device is opposite to a forward direction of the inclined section of the second chain plate.

[0007] Further, the material feeding device includes a material feeding wheel, and the material feeding wheel is driven to rotate by a motor through a rotating shaft connected to the motor.

[0008] Further, a plurality of paddles are circumferentially arrayed on the circumferential surface of the material feeding wheel with the central axis of the material feeding wheel as the center, and the paddles are stepped paddles that are symmetric about the left and right.

[0009] Further, a frame body for connecting the material feeding device is provided on the inclined section of the second chain plate. A group of parallel channel steels perpendicular to the inclined section of the second chain plate are provided on the frame body. A plurality of equidistant motor positioning holes are provided on the channel steels. The height of the motor from the surface of the inclined section of the second chain plate is adjusted by installing the motor into the motor positioning holes at different positions.

[0010] Further, the other end of the inclined section of the second chain plate is close to the discharge port.

[0011] Further, the motor positioning holes are threaded holes, and the motor is fixed to the motor positioning holes by bolts.

[0012] Further, the bottom of the first chain plate is supported by a support member, and the support member is a telescopic member. The horizontal height of the first chain plate is adjusted by adjusting the height of the telescopic member.

[0013] Further, the telescopic member is a first support member with an external thread and a second support member with an internal thread. The internal thread of the second support member is matched with the external thread of the first support frame. The height of the telescopic member is changed by rotating the second support member.

[0014] Further, the baffle is a vertical baffle.

[0015] The technical solution of the present utility model has the following advantages:

[0016] 1. The present utility model is provided with two chain plates having a horizontal height difference. When the material moves along with the first chain plate and falls from the material output end of the first chain plate to the material input end of the horizontal section of the second chain plate, the material has an initial horizontal velocity given by the first chain plate. Therefore, it falls onto the horizontal section of the second chain plate in a parabolic form. When the material that is grouped together during the falling process contacts the surface of the horizontal section of the second chain plate, it will be loosened due to a certain degree of impact force, playing a role in evenly distributing the material.

[0017] 2. By arranging two chain plates connected end to end, the present utility model can further evenly distribute materials by setting different moving speeds of the first chain plate and the second chain plate. For example, when there is a large amount of materials, the moving speed of the first chain plate is set slower than that of the second chain plate. In this way, the materials falling on the second chain plate can be quickly transported away relative to the feeding speed of the first chain plate, and no accumulation will occur at the junction, thus playing a role in evenly distributing materials. Since there is a storage space above the first chain plate, which is a bunker, and there are baffles to block large materials, the moving speed of the first chain plate can be relatively slower than that of the second chain plate. In this way, according to the feeding situation, the speed difference between the first chain plate and the second chain plate can be accurately adjusted to achieve a better material distribution effect.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the field to which the present utility model belongs.

Similarly, unless the context clearly indicates otherwise, the singular forms "a", "an" or "the" and similar terms do not indicate a quantity limitation, but mean that there is at least one.

The terms "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0029] The chain plate conveyors in the prior art generally use single-chain transportation. The silo space above the chain has a small size. The incoming material falls onto the upper surface of the transportation chain and moves forward along with the advancing direction of the chain before it has time to be evenly loosened. Moreover, the speed of the material moving after falling from the feed inlet onto the single chain is the same as the conveying speed of the single chain. The speed at which the silo digests the material depends on the transportation speed of the single chain. The speed of the silo digesting the material cannot be flexibly adjusted independently of the transportation speed of the single chain, and the material cannot play a role in equalizing the material during the transportation process.

[0030] Based on the above problems, the embodiments of the present utility model provide a double-chain plate conveyor for equalizing materials, which has a good equalizing effect and the thickness of the transported materials is uniform, overcoming the problem of uneven material transmission of traditional chain plate conveyors.

[0031] Please refer to Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a material leveling double-chain plate conveyor, which includes chain plates and a driving mechanism. The driving mechanism is used to drive the chain plates to move. The driving mechanism in the embodiment of the present utility model can adopt the driving mechanism in the prior art. The driving mechanism includes a motor, a reducer, and a transmission shaft, which are used to provide conveying power. The motor transmits the power to the transmission shaft through the reducer, and the transmission shaft transmits the power to the chain plates through sprockets. The sprockets and chains are one of the core components of the chain plate conveyor. The sprockets are connected to the chain plates through the chains, and the power is transmitted to the chain plates, so that the chain plates move along the conveying direction.

[0032] The chain plates in the embodiment of the present utility model include a first chain plate 2 and a second chain plate. The first chain plate 2 is horizontally arranged. The second chain plate includes a second chain plate horizontal section 3 and a second chain plate inclined section 4 that are integrally connected. The first chain plate 2 is arranged on one side close to the second chain plate horizontal section 3, and the horizontal height of the first chain plate 2 is higher than the horizontal height of the second chain plate horizontal section 3. By setting the height difference between the two chain plates, when the material moves with the first chain plate 2 and falls from the material output end of the first chain plate 2 into the material input end of the second chain plate horizontal section 3, the material has the horizontal initial velocity given by the first chain plate 2, so it falls onto the second chain plate horizontal section 3 in a parabolic form. When the material that is grouped together during the falling process touches the surface of the second chain plate horizontal section 3, it will be loosened due to a certain degree of impact force, playing a role in leveling the material.

[0033] A material bin 6 is provided above the first chain plate 2 and the second chain plate horizontal section 3. A baffle 5 is provided in the material bin 6. The bottom of the baffle 5 is located at the junction of the first chain plate 2 and the second chain plate horizontal section 3. There is a gap between the bottom of the baffle 5 and the upper surface of the first chain plate 2. A feed inlet 1 is provided directly above the first chain plate 2.

[0034] When the material falls from the feed inlet 1 into the material bin 6, it only stays on the first chain plate 2. By setting the moving speed of the first chain plate 2 and the moving speed of the second chain plate, the material can be further leveled. For example, when there is more material, the moving speed of the first chain plate 2 is set slower than the speed of the second chain plate. In this way, the material falling onto the second chain plate can be quickly transported away relative to the feeding speed of the first chain plate 2, and no accumulation will occur at the junction, playing a role in leveling the material. Since there is a material bin 6 above the first chain plate 2, there is a storage space, and the baffle 5 blocks large pieces of material, so the moving speed of the first chain plate 2 can be relatively slower than that of the second chain plate. In this way, according to the feeding situation, the speed difference between the first chain plate 2 and the second chain plate can be accurately adjusted to achieve a better material leveling effect.

[0035] There is a gap between the bottom of the baffle 5 and the upper surface of the first chain plate 2. The height of the gap determines the maximum thickness of the material that can pass through, ensuring that the material can pass only after it is loosened from a large mass to small pieces of uniform thickness. In this way, the thickness of the material transported to the second chain plate is more uniform, and the material thickness will not be too large.

[0036] In some embodiments of the present invention, a material shifting device 7 is further mounted on the second chain plate inclined section 4 , and a material shifting direction of the material shifting device 7 is opposite to a forward direction of the second chain plate inclined section 4 .

[0037] In addition to loosening the material by setting the height difference between the first chain plate 2 and the second chain plate horizontal section 3, the embodiment of the utility model also sets a second line of defense for uniform material on the second chain plate inclined section 4, and by installing a material shifting device 7, the material transported to the position of the material shifting device 7 is shifted, and external force is applied to the surface of the material to further loosen the thicker material. Since the direction of shifting the material is opposite to the direction of material advance, the shifting contact is more complete, and only the material with a thickness lower than the height of the gap between the material shifting device 7 and the second chain plate inclined section 4 can pass, further breaking up and uniforming the material.

[0038] See also Figures 2 to 4 As shown, in some embodiments of the present invention, the material tapping device 7 includes a material tapping wheel 71, and the material tapping wheel 71 is connected to a rotating shaft of the motor and driven by the motor to rotate.

[0039] In some embodiments of the present invention, a plurality of paddles 72 are arranged on the circumferential surface of the paddle wheel 71 in a circumferential array with the central axis of the paddle wheel 71 as the center, and the paddles 72 are bilaterally symmetrical stepped paddles 72 .

[0040] The embodiment of the utility model increases the contact area with the material by designing the paddle 72 into a bilaterally symmetrical stepped shape, making it easier to pry apart the clumped materials, thereby achieving a more complete effect of loosening the materials and a higher loosening efficiency.

[0041] In some embodiments of the utility model, a frame for connecting the material discharging device 7 is provided on the second chain plate inclined section 4, and a group of parallel channel steels perpendicular to the second chain plate inclined section 4 are provided on the frame, and a plurality of equidistant motor positioning holes are provided on the channel steels. The motor is installed in the motor positioning holes at different positions to achieve height adjustment of the motor from the surface of the second chain plate inclined section 4.

[0042] By adjusting the height of the motor from the surface of the second inclined link plate 4, the height of the material pushing device 7 from the surface of the second inclined link plate 4 is adjusted. In fact, this is to adjust the thickness of the material on the second inclined link plate 4 that can pass through the material pushing device 7. Therefore, designing motor positioning holes at different positions can meet the requirements for the degree of uniform material in different scenarios.

[0043] In some embodiments of the present invention, the other end of the second inclined link plate 4 is close to the discharge port 8.

[0044] In some embodiments of the present invention, the motor positioning holes are threaded holes, and the motor is fixed to the motor positioning holes by bolts. The threaded connection is convenient for installation and disassembly.

[0045] In some embodiments of the present invention, the bottom of the first link plate 2 is supported by a support member, and the support member is a telescopic member. By adjusting the height of the telescopic member, the horizontal height of the first link plate 2 is adjusted.

[0046] In some embodiments of the present invention, the telescopic member is a first support member with an external thread and a second support member with an internal thread. The internal thread of the second support member cooperates with the external thread of the first support frame. By rotating the second support member, the height of the telescopic member is changed.

[0047] By adjusting the height of the telescopic member to adjust the horizontal height of the first link plate 2, the horizontal height of the first link plate 2 determines the height difference between the first link plate 2 and the horizontal section 3 of the second link plate, and also determines the size of the gap between the baffle 5 and the upper surface of the first link plate 2. These two data determine the degree of material uniformity. The higher the height difference between the first link plate 2 and the horizontal section 3 of the second link plate determined by the horizontal height of the first link plate 2, the easier the material is to loosen when it is thrown onto the second link plate. The smaller the gap between the baffle 5 and the upper surface of the first link plate 2, the smaller the thickness of the material that can pass through. Therefore, by adjusting the telescopic member, the requirements for uniform different materials in different scenarios can be met on the same link plate machine, which is more economical and applicable.

[0048] In some embodiments of the present invention, the baffle 5 is a vertical baffle, which divides the material bin 6 into two spaces above the first link plate 2 and the horizontal section 3 of the second link plate, facilitating the coordinated control of the material transportation speed by the link plates.

[0049] In summary, the utility model improves the uniformity of materials during transportation by arranging two chain plates connected end to end, adding a baffle 5 directly above the connection of the first chain plate 2 and the second chain plate in the silo 6 with a gap left between the baffle 5 and the upper surface of the first chain plate 2. On this basis, a material distributing device 7 is arranged in the moving direction of the second chain plate to further even the materials. Therefore, the utility model achieves the effect of thoroughly and fully evening the materials during transportation.

[0050] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various modifications and refinements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the claims.
