Description

Technical Field

[0001] The invention relates to the technical field of conveyor belt midway unloading, in particular to a novel conveyor belt midway unloading device. Background Art

[0002] When conveying materials on a conveyor belt, there is sometimes a need for unloading at multiple points along the way. To meet such needs, the existing technology usually uses a plow-type unloader for unloading. The plow-type unloader uses a push rod to lower the plow blade to press the conveyor belt, and the linkage mechanism lifts the flat roller group under the conveyor belt to change the conveyor belt from a trough shape to a flat state. The conveyor belt is sandwiched in the middle by the plow blade and the roller group. After waiting for the material to arrive, the plow blade is used to support the material flow, and then the conveyor belt's own speed is used to hit the material onto the plow blade, thereby squeezing the material to both sides and causing the material to fall into the silo. After waiting for the unloading to be completed, the push rod raises the plow blade to separate the plow blade from the surface of the conveyor belt.

[0003] The existing plow type unloader generally has the following use defects and shortcomings:

[0004] 1. It is easy to cause damage to the rubber surface of the conveyor belt. The operation mode of the existing plow type discharger determines that the contact between the bottom of the plow blade and the conveyor belt is difficult to control. If the contact is tight, the plow blade is easy to wear the rubber surface of the conveyor belt. If the contact is loose, block materials are easy to be mixed between the plow blade and the conveyor belt, causing scratches or penetration of the conveyor belt.

[0005] 2. Material residue. Existing plow-type unloaders generally use a working mode of alloy high chromium manganese front plowshare and wear-resistant polyester rear plowshare. The plowshare and conveyor belt cannot achieve perfect coordination, which will lead to unclean material unloading during use and require manual regular cleaning, otherwise it will cause other faults, which is time-consuming and labor-intensive.

[0006] 3. The running speed is limited. In order to ensure the unloading effect and reduce the wear of the conveyor belt, the running speed of the plow type unloader cannot be too high, usually in the range of 0.8 to 2.5 m / s.

[0007] 4. High maintenance requirements. The existing plow type unloader has many moving parts, which are exposed to the outside. The failure rate is high due to the influence of on-site dust and water vapor. It is necessary to regularly check the key parts such as the push rod, locking device, and plow blade, and the maintenance cost is high.

[0008] 5. Unable to effectively divide materials in proportion. The existing plow-type unloader cannot achieve proportional material division and can only meet the requirements of total unloading. If the site needs to divide materials in proportion, a new conveying system needs to be added, which greatly increases the production cost of the enterprise. Summary of the invention

[0009] The object of the present invention is to provide a new type of conveyor belt mid-way discharging device to solve the technical problems existing in the prior art. The preferred technical solutions among the many technical solutions provided by the present invention can produce many technical effects as described in detail below.

The discharging roller is movably connected to the frame body and is located at the high-position end. The cage-type roller is connected to the self-propelled unit and is located obliquely in front and below the discharging roller.

[0014] Preferably, the material distributing unit comprises a frame housing, a central shaft and a connecting ring. A central shaft is connected to each of the left and right sides of the frame housing. Both central shafts are rotationally connected to the self-propelled unit. The connecting ring is connected to the top of the frame housing. The connecting ring is movably connected to the execution unit. Wear-resistant lining plates are laid on the inner wall surface of the frame housing.

[0038] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "center", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc. are based on the Figure 1 orientation or positional relationship shown, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0040] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Referring to Figures 1 to 8 , the present invention provides a new type of conveyor belt mid-way discharging device, which includes a self-propelled unit 1, a gradually changing frame unit 2, a material distribution unit 3, and an execution unit 4.

[0042] The self-propelled unit 1 is a frame component of the device, used to carry the above-mentioned gradually changing frame unit 2, material distribution unit 3, and execution unit 4, and the self-propelled unit 1 can drive the whole device to move, so as to adjust the relative position of the device. When there are multiple discharging points on a conveyor belt, the self-propelled unit 1 can move back and forth parallel to the running direction of the conveyor belt 5 according to the actual requirements on site, ensuring that the discharging and material distribution requirements can be met at each falling point.

[0043] The material distribution unit 3 is provided with a main channel 34 and a material distribution channel 35. The main channel 34 and the material distribution channel 35 are independent of each other and do not communicate with each other. The main channel 34 is parallel to the traveling direction of the conveyor belt 5 and is located on the same straight line. The main channel 34 is a straight-through channel. The material on the conveyor belt 5 can maintain a normal conveying state after falling into the main channel 34 without changing its conveying effect. The material distribution channel 35 can achieve material distribution. The material on the conveyor belt 5 can change its conveying effect after falling into the material distribution channel 35, realizing mid-way discharging.

[0044] The gradient rack unit 2 is connected to the self-propelled unit 1 and is in driving connection with the conveyor belt 5. The conveyor belt 5 driven in the corresponding section of the gradient rack unit 2 can lift its height along the traveling direction of the self-propelled unit 1. One end of the gradient rack unit 2 close to the material distribution unit 3 forms the above-mentioned high position end. The conveyor belt 5 reaches the highest point at the high position end and forms a material dropping point. The material on the conveyor belt 5 can fall into the main channel 34 or the material distribution channel 35 here. After the material dropping is completed, the conveyor belt 5 gradually descends in height under the drive of the cage drum 24 and finally returns to the form without the lifted angle, forming a cyclic operation.

[0045] The material distribution unit 3 is movably connected to the self-propelled unit 1, and the execution unit 4 is connected to the self-propelled unit 1. At the same time, the material distribution unit 3 is in driving connection with the execution unit 4. After the execution unit 4 is started, it can drive the material distribution unit 3, thereby driving the material distribution unit 3 to adjust the angle or change the position. Therefore, the execution unit 4 can drive the main channel 34 and the material distribution channel 35 to move and can independently select to switch the main channel 34 or the material distribution channel 35 to move below the high position end of the gradient rack unit 2. When the main channel 34 moves below the high position end of the gradient rack unit 2, the material on the conveyor belt 5 can fall into the main channel 34. When the material distribution channel 35 moves below the high position end of the gradient rack unit 2, the material on the conveyor belt 5 can fall into the material distribution channel 35.

[0046] It should be noted that the above conveyor belt 5 is essentially the total conveyor belt for continuous operation on the production line. The new conveyor belt intermediate unloading device essentially realizes the angle lifting of the conveyor belt 5 through the gradient rack unit 2 and forms a material dropping point. Then the conveyor belt 5 gradually descends to the form without the lifted angle. The conveyor belt 5 is always the same total conveyor belt. If the self-propelled unit 1 drives the whole new conveyor belt intermediate unloading device to travel, the angle of the conveyor belt 5 in the corresponding section will be adjusted.

[0047] Compared with the prior art, the new conveyor belt intermediate unloading device creatively puts forward a brand-new material distribution concept. With the mutual cooperation of the self-propelled unit 1, the gradient rack unit 2, the material distribution unit 3 and the execution unit 4, except for the gradient rack unit 2, the other components no longer have direct contact with the conveyor belt 5, and the gradient rack unit 2 only plays a supporting role for the conveyor belt 5 and does not generate contact pressure on the conveyor belt 5. In this way, it can avoid the contact between the material distribution unit 3 and the conveyor belt 5 and effectively reduce the wear and scratch on the surface of the conveyor belt 5;

[0048] The self-propelled unit 1 can drive the whole device to move freely, thus meeting the discharging requirements at multiple positions in different time periods. The gradient rack unit 2 can lift the conveyor belt 5 in height, changing the space and distance of the conveyor belt 5, realizing unobstructed diversion and discharging of materials. The overall structure of the new conveyor belt intermediate discharging device is more concise, with high reliability, more convenient installation and maintenance, which can reduce the labor intensity of on-site personnel, and reduce the labor and time costs required for cleaning the spilled materials. There are very few moving parts in the device, so the on-site maintenance difficulty can be greatly reduced and the maintenance cost can be alleviated.

[0049] As an optional implementation manner, the self-propelled unit 1 includes a self-propelled rack 11, self-propelled wheels 12, a self-propelled motor, and a self-propelled track 13;

[0050] The self-propelled rack 11 is the main frame structure of the self-propelled unit 1, which is used to carry the above-mentioned gradient rack unit 2, the material distribution unit 3, and the execution unit 4. The gradient rack unit 2, the material distribution unit 3, and the execution unit 4 are all connected to the self-propelled rack 11;

[0051] The self-propelled track 13 is laid on the ground, and its length direction is consistent with the overall traveling direction of the conveyor belt;

[0052] The self-propelled wheels 12 are connected to the bottom of the self-propelled rack 11, and the self-propelled motor is connected to the self-propelled rack 11 and is drivingly connected to the self-propelled wheels 12;

[0053] After the self-propelled motor is started, it can drive the self-propelled wheels 12, thereby driving the self-propelled wheels 12 to rotate. The self-propelled rack 11 can move on the self-propelled track 13 through the self-propelled wheels 12 to realize the requirement of intermediate multi-point discharging. The self-propelled motor can drive the self-propelled wheels 12 to rotate forward or backward, so that it can move self-propelled in both the front and back directions.

[0054] As an optional implementation manner, the gradient rack unit 2 includes a rack body 21, a roller group 22, a discharging roller 23, and a cage roller 24;

[0055] The rack body 21 is connected to the self-propelled rack 11 of the self-propelled unit 1. The rack body 21 is inclined, with the end close to the material distribution unit 3 being the high position end and the end far from the material distribution unit 3 being the low position end;

[0056] The roller group 22 is connected to the rack body 21, and the roller group 22 can support the conveyor belt 5;

[0057] The discharging roller 23 is movably connected to the rack body 21 and is located at the high position end. The cage roller 24 is connected to the self-propelled unit 1 and is located obliquely in front and below the discharging roller 23;

[0058] The conveyor belt 5 gradually raises its height with the assistance of the idler roller group 22 at the low end of the frame body 21, reaches the highest point at the discharge roller 23, and forms a material dropping point. The material falls into the main channel 34 or the material distribution channel 35 at this point. After the material dropping is completed, the conveyor belt 5 gradually descends in height driven by the cage roller 24 and finally returns to the form without the lifted angle, forming a cyclic operation.

[0059] As an alternative embodiment, the material distribution unit 3 includes a frame housing 31, a central shaft 32, and a connecting ring 33;

[0060] The frame housing 31 is preferably made of steel material, which has better structural strength. Wear-resistant liners are laid on the inner wall surface of the frame housing 31, that is, wear-resistant liners are laid on the plates forming the main channel 34 and the material distribution channel 35. Here, the wear-resistant liners are preferably made of wear-resistant ceramic material with 92% alumina content. By installing the wear-resistant liners in advance, the wear resistance of the inner wall surface of the frame housing 31 can be improved, achieving an extremely long service life;

[0061] One central shaft 32 is connected to each of the left and right sides of the frame housing 31, and both central shafts 32 are rotationally connected to the self-propelled frame 11 of the self-propelled unit 1. The connecting ring 33 is connected to the top of the frame housing 31, and the connecting ring 33 is movably connected to the execution unit 4. After the execution unit 4 is started, it can drive the frame housing 31 to rotate relative to the self-propelled frame 11 through the central shaft 32.

[0062] As an alternative embodiment, for better structural layout, the interior of the frame housing 31 is preferably a double-layer structure, and the double-layer structure respectively forms the main channel 34 and the material distribution channel 35;

[0063] The specific positions of the main channel 34 and the material distribution channel 35 can be flexibly selected and set, that is, the main channel 34 can be relatively located above the material distribution channel 35, or the main channel 34 can also be relatively located below the material distribution channel 35. In this embodiment, the structural form with the main channel 34 located above the material distribution channel 35 is preferably shown.

[0064] As an alternative embodiment, the discharge port of the main channel 34 contracts inward to form a cone. The conical discharge port can improve the discharge accuracy of the main channel 34 and can also improve the discharge speed.

[0065] In this embodiment, there are relatively rich choices for the specific structural form of the material distribution channel 35, so there are also relatively rich choices for the overall structural form of the material distribution unit 3;

[0066] As one major category, the material distribution channel 35 has a consistent feed port and forms a difference in the setting method of the discharge port;

[0067] Refer toFigure 4 , the discharge port of the material distribution channel 35 may separately include a left discharge port 351 facing left;

[0068] Refer to Figure 5 , or may separately include a right discharge port 352 facing right;

[0069] Refer to Figure 3 , or may simultaneously include a left discharge port 351 facing left and a right discharge port 352 facing right. If both the left discharge port 351 and the right discharge port 352 are included, the left discharge port 351 and the right discharge port 352 are located on the same working plane, and the inclination angle can be adjusted according to actual setting requirements. Therefore, under this classification condition, the material distribution channel 35 evolves into three different structural forms;

[0070] When it is required to split the material to both sides, the discharge port of the material distribution channel 35 should select the structure of a three-way material distribution port that simultaneously includes the left discharge port 351 and the right discharge port 352. When it is required to split the material to the right, the discharge port of the material distribution channel 35 should select the structure that only includes the right discharge port 352. When it is required to split the material to the left, the discharge port of the material distribution channel 35 should select the structure that only includes the left discharge port 351.

[0071] As another major category, the difference from the above major category is that during the actual material distribution process, there may be a situation of simultaneous direct discharge and material distribution, that is, a situation where some materials are discharged normally and some materials are distributed;

[0072] In this type, the material distribution channel 35 has a consistent feed port, and there are differences in the setting method of the discharge port;

[0073] The discharge port of the material distribution channel 35 includes a rear discharge port 353 with the same discharge direction as the main channel 34 and side discharge ports. The discharge direction of the rear discharge port 353 is parallel to and on the same straight line as the discharge direction of the main channel 34. The side discharge ports include a left discharge port 351 facing left and / or a right discharge port 352 facing right. The rear discharge port 353, the left discharge port 351, and the right discharge port 352 are located on the same working plane;

[0074] That is, the side discharge port may separately include a left discharge port 351 facing left, or may separately include a right discharge port 352 facing right, or may simultaneously include a left discharge port 351 facing left and a right discharge port 352 facing right.

[0075] Therefore, under this classification condition, the material distribution channel 35 evolves into another three different structural forms;

[0076] The first form, refer toFigure 6 The discharge port of the material distribution channel 35 includes a rear discharge port 353 and a left discharge port 351. After a part of the material enters the rear discharge port 353, it returns to the conveyor belt 5 and continues to move forward. Another part of the material directly enters the corresponding bin after entering the left discharge port 351, realizing the midway unloading of the material.

[0077] The second form, referring to Figure 7 The discharge port of the material distribution channel 35 includes a rear discharge port 353 and a right discharge port 352. After a part of the material enters the rear discharge port 353, it returns to the conveyor belt 5 and continues to move forward. Another part of the material directly enters the corresponding bin after entering the right discharge port 352, realizing the midway unloading of the material.

[0078] The third form, the discharge port of the material distribution channel 35 includes a rear discharge port 353, a left discharge port 351 and a right discharge port 352. After a part of the material enters the rear discharge port 353, it returns to the conveyor belt 5 and continues to move forward. Another part of the material directly enters the corresponding bin after entering the left discharge port 351. The last part of the material directly enters the corresponding bin after entering the right discharge port 352, realizing the midway unloading of the material.

[0079] And it is worth noting that for the above three forms, the discharge ratio of the material at each discharge port branch can also be adjusted through structural design to achieve different ratios of midway unloading under different application scenarios.

[0080] In this embodiment, the frame housing 31 is preferably detachably connected to the self-propelled frame 11, so it can be more flexibly disassembled and installed from the self-propelled frame 11. For the material distribution unit 3 with the above multiple different structural forms, it can be flexibly selected and installed according to actual usage requirements.

[0081] As an optional implementation manner, the execution unit 4 includes a fixed seat 41 and a push rod 42. The fixed seat 41 is connected to the self-propelled unit 1, and the push rod 42 is connected to the fixed seat 41 and is drivingly connected to the material distribution unit 3;

[0082] By extending and retracting the push rod 42, the pitching motion of the material distribution unit 3 can be controlled, so that the frame housing 31 can rotate relative to the central axis 32 by an angle, thereby selecting and switching the main channel 34 or the material distribution channel 35 to move below the high end of the gradient frame unit 2;

[0083] When the material needs to pass through directly, the push rod 42 extends to align the feed port of the main channel 34 with the discharge roller 23, and the material returns to the surface of the conveyor belt 5 through the discharge port of the main channel 34;

[0084] When intermediate discharging is required, the push rod 42 contracts, aligning the feed inlet of the material distribution channel 35 with the discharging roller 23, and the material is diverted into the silo through the discharge outlet of the material distribution channel 35.

[0085] As an optional implementation manner, referring to Figure 8 , it further includes a control box 6, which is connected to the self-propelled unit 1 and communicatively connected to the self-propelled unit 1 and the execution unit 4;

[0086] The control box 6 can control the start and stop of the push rod 42 of the execution unit 4 and can make corresponding actions according to instructions. The control box 6 can also control the start and stop of the self-propelled motor of the self-propelled unit 1, driving the new conveyor belt intermediate discharging device to move to different positions;

[0087] By selecting control boxes 6 with different functions, all operations of the new conveyor belt intermediate discharging device can be executed by the control box, enabling on-site manual start and stop control, as well as remote control and fault alarm functions. The application principle of such control through the control box 6 is conventional technology, so no further elaboration will be made.

[0088] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
