DETAILED DESCRIPTION

[0023] The utility model is further described below in combination with the drawings.

[0024] It should be noted that if the utility model involves directional indication language, such as up, down, left, right, front, back, and directional language, it is for the convenience of the description of the relative position between components, not for the absolute position of the related components or the position relationship between components, and is only used to explain the relative position relationship between components, movement conditions, etc. in a certain posture, if the specific posture changes, the directional indication also changes accordingly. If the utility model involves quantity language, such as "many", "multiple", "several", etc., it specifically refers to two or more than two.

[0025] As Figures 1-3 shown, the utility model provides a kind of push rod drive type cloth device, including rack 1, and cloth conveyor 2 and transfer conveyor 3 respectively being arranged in the front and rear ends of rack 1, the bottom of rack 1 is equipped with travelling mechanism 4, the feeding end of cloth conveyor 2 and rack 1 are equipped with rotary support 5, rotary support 5 and rack 1 are rotationally connected by first rotary mechanism 11, rotary support 5 and the base 21 of the feeding end of cloth conveyor 2 are rotationally connected by second rotary mechanism 12, the rotation axes of first rotary mechanism 11 and second rotary mechanism 12 are vertical direction, they can be coaxial also can be different shaft, but preferably coaxial. First telescopic rod 13 is equipped between rack 1 and rotary support 5, second telescopic rod 14 is equipped between rotary support 5 and base 21, the feeding end of cloth conveyor 2 and base 21 are rotationally connected by horizontal rotation axis, third telescopic rod 15 is equipped between the part of cloth conveyor 2 close to feeding end and base 21, the feeding end of transfer conveyor 3 is located on rack 1, the feeding end of transfer conveyor 3 and the feeding end of cloth conveyor 2 are opposite.

[0026] The approximate working process of the utility model is: first, the distributing device is placed in the granary, then a feeding belt conveyor is erected between the grain unloading device outside the granary and the distributing device, the feeding belt conveyor is connected with the feeding end of the transfer conveyor 3, the grain is transferred to the feeding end of the distributing conveyor 2 through the transfer conveyor 3, and finally the grain is distributed through the distributing conveyor 2. During the distribution process, the distributing conveyor 2 can rotate in the horizontal direction around the first rotary mechanism 11 and the second rotary mechanism 12 under the push-pull action of the first telescopic rod 13 and the second telescopic rod 14, and can rotate in the vertical plane under the push-pull action of the third telescopic rod 15, so that the grain can be distributed in a large range without moving the distributing device, at the same time, the transfer conveyor 3 can be connected with the feeding belt conveyor, so that continuous distribution is realized, the moving frequency of the distributing device is reduced, the grain storage efficiency is effectively improved, and the labor intensity and energy consumption of workers are reduced.

[0027] The rack 1 is used as a bearing main body, and its structure form and structure strength need to meet the stability of the equipment distribution, avoid the equipment overturning, and at the same time, its structure size should be adapted to the arrangement interval of the ordinary flat warehouse cage, so as to ensure that the rack 1 can move in the interval space of the ground cage. The walking mechanism 4 can adopt the form of rollers or tracks and be driven by a motor, and both have advantages and disadvantages, the roller is more flexible, and the track is more stable, so that the roller can be used when the conveying capacity is small, and the track can be used when the conveying capacity is large. In addition, the walking mechanism 4 can be remotely controlled to run, improve the safety of operation, and avoid the influence of dust on the health of workers.

[0028] In order to increase the distribution range of the distributing device, the distributing conveyor 2 can preferably be a telescopic belt conveyor, and the telescopic range can be designed according to the anti-overturning ability of the equipment, the rotation range of the distributing conveyor 2 and the grain loading requirement. Preferably, when the distributing device is located on the central axis of the granary, the length of the distributing conveyor 2 can meet the distribution requirements of the granary areas on both sides, so that only the distributing device needs to move along the central axis of the granary during the distribution process, and the moving frequency of the distributing device can be further reduced.

[0029] Because the fabric conveyor 2 is equipped with a rotating support 5, a first rotating mechanism 11, and a second rotating mechanism 12 between it and the frame 1, it is relatively high. In order to meet the docking requirements with the fabric conveyor 2, the transfer conveyor 3 is preferably an inclined belt conveyor or a scraper elevator. The feed end of the transfer conveyor 3 is directly attached to the frame 1. In this way, the feed belt conveyor that comes in from outside the warehouse and is connected to the feed end of the transfer conveyor 3 does not need to be erected very high, which can ensure the stability of the installation of the transfer conveyor 3 and the grain receiving. In addition, to facilitate the grain connection between the transfer conveyor 3 and the cloth conveyor 2, a receiving hopper can be set at the feed end of the transfer conveyor 3 and the cloth conveyor 2, and a discharge hopper can be set at the discharge end of the transfer conveyor 3. When the cloth conveyor 2 is in a horizontal state, the axes of the discharge hopper, the receiving hopper, the first rotating mechanism 11 and the second rotating mechanism 12 are preferably coaxial, which can ensure that the discharge end of the transfer conveyor 3 can always be connected to the feed end of the cloth conveyor 2 when the cloth conveyor 2 is rotating.

[0030] For the first rotary mechanism 11 and the second rotary mechanism 12, flange bearings are preferred to ensure structural stability and facilitate equipment installation.

[0031] Since the rotation angle of the fabric conveyor 2 is controlled by each telescopic rod, its load-bearing capacity and control precision are required to be high. Therefore, the preferred embodiment of this application is that the first telescopic rod 13, the second telescopic rod 14, and the third telescopic rod 15 are all hydraulic rods, and the frame 1 is equipped with a matching hydraulic system 6. Compared with electric lead screws, hydraulic rods have greater pushing and pulling force, better self-locking ability, and are easier to install and control, thereby achieving precise adjustment of the fabric placement point and stability during the fabric placement process. Specifically, during installation, the two ends of the first telescopic rod 13 are hinged to the frame 1 and the rotary support 5, respectively; the two ends of the second telescopic rod 14 are hinged to the rotary support 5 and the base 21, respectively; and the two ends of the third telescopic rod 15 are hinged to the base 21 and the fabric conveyor 2, respectively.

[0032] Regarding the rotation of the fabric conveyor 2 in the horizontal plane, this application adopts a two-stage rotation structure consisting of a first rotating mechanism 11 and a second rotating mechanism 12 because the extension and retraction range of the first telescopic rod 13 and the second telescopic rod 14 is limited, and in order to reduce equipment movement, the fabric conveyor 2 needs to rotate within a 180° range. Specifically, Figure 3 The fabric conveyor 2 shown is positioned with the front end of the frame 1 as a reference. Figure 4 As shown, the first telescopic rod 13 allows the rotating bracket 5 to rotate in a horizontal direction within a range of not less than 0-90°, such as... Figure 5As shown, the second telescopic rod 14 can make the cloth conveyor 2 rotate in another horizontal direction within a range of not less than 0-90°. The angle in the vertical direction should be considered comprehensively according to the cloth height and the effective conveying angle of the belt conveyor, and according to the angle of the conventional inclined belt conveyor, the third telescopic rod 15 can make the cloth conveyor 2 rotate in the vertical direction within a range of not less than 0-60°.

[0033] In addition, in order to improve the anti-overturning ability of the device, the counterweight 51 is arranged at one end of the rotary support 5 close to the transfer conveyor 3. In order to realize the cloth height control and avoid collision with the wall, the front end of the cloth conveyor 2 is provided with a collision sensor 22 and a grain surface height sensor 23, as shown. Figure 6 In order to realize the electromechanical control of the whole device and automatic cloth, the rack 1 is provided with an electric control cabinet 7 for controlling the operation of each component, including the operation of the traveling mechanism 4, the rotation angle and the telescopic length of the cloth conveyor 2, and the signal receiving of the collision sensor 22 and the grain surface height sensor 23. Among them, the collision sensor 22 and the grain surface height sensor 23 are both mature products, and the control system of the electric control cabinet 7 is also prior art. The present application only needs to purchase appropriate existing products according to the demand, and the specific control and detection process is not described.

[0034] The preferred working process of the cloth device is: running the device to the predetermined position, before cloth, the hydraulic system 6 controls the first telescopic rod 13, the second telescopic rod 14 and the third telescopic rod 15 through the control of the electric control cabinet 7, adjusts the horizontal angle and the pitch angle of the cloth conveyor 2, and adjusts the length of the cloth conveyor 2 at the same time, so that the discharge end of the cloth conveyor 2 reaches the predetermined cloth point, then a feeding belt conveyor is erected between the grain unloading device outside the warehouse and the cloth device, the feeding belt conveyor is connected with the feeding end of the transfer conveyor 3, and the above work is completed. Start the cloth operation. During the cloth process, the collision sensor 22 monitors in real time to avoid collision between the cloth conveyor 2 and the wall in the warehouse, and the grain surface height detection sensor 23 monitors the grain surface height in real time, feeds the signal to the control center in the electric control cabinet 7, and synchronously adjusts the height and length of the cloth conveyor 2, so as to ensure that the relative height of the grain throwing position of the cloth conveyor 2 and the grain surface always remains consistent, thereby effectively reducing the grain breakage rate, avoiding the classification phenomenon between grains due to the difference in quality and size, and being conducive to sampling and storage work. When the grain surface height of the cloth point reaches the predetermined position, the control center sends instructions to the first rotary mechanism 11 and the second rotary mechanism 12 according to the feedback signal, and controls the rotation angle of the cloth conveyor 2 by using the first telescopic rod 13 and the second telescopic rod 14, so that the discharge end of the cloth conveyor 2 reaches the next cloth point, until the cloth in the range of 180° in front of the device is completed. Then stop the machine, move the device to the next predetermined position, and adjust the feeding belt conveyor outside the warehouse at the same time, continue to cloth, until the cloth work of the whole grain warehouse is completed.
