DETAILED DESCRIPTION

[0026] The utility model is further described below in connection with the drawings.

[0027] It needs to be explained that if the utility model has involved directional indication language, such as up, down, left, right, front, back, direction, orientation language, it is for the description of the relative position connection of components, not the absolute position of the relevant components, the position relationship between components, only for explaining the relative position relationship, movement condition between components in a certain posture, if the specific posture changes, then the direction indication also changes accordingly.If the utility model has involved the language of quantity, such as " many ", " multiple ", " several " and the like, it specifically refers to two and two or more.

[0028] For example, Figures 1-5The utility model provides a kind of cloth device of hydraulic motor drive shown, including rack 1, and cloth conveyor 2 and transfer conveyor 3 respectively arranged in the front and rear ends of rack 1, the base 21 of the feed end of cloth conveyor 2 is equipped with rotary mechanism 5 between rack 1, the rotary mechanism 5 is vertical direction, the one end of rotary mechanism 5 and base 21 fixed connection coaxially is equipped with gear disc 51, the part of rack 1 close to rotary mechanism 5 is equipped with mounting seat 6, mounting seat 6 is equipped with hydraulic motor 7, the rotary shaft of hydraulic motor 7 is equipped with the driving gear 71 meshed with gear disc 51, rack 1 is equipped with hydraulic system 8 for providing hydraulic oil for hydraulic motor 7, the feed end of cloth conveyor 2 is connected by horizontal rotary shaft between base 21, the part close to the feed end of cloth conveyor 2 and base 21 is equipped with telescopic link 22, telescopic link 22 is also provided with hydraulic oil by hydraulic system 8, transfer conveyor 3 is fixed on rack 1, and the feed end of transfer conveyor 3 is opposite to the feed end of cloth conveyor 2.

[0029] The utility model's roughly working process is: first cloth device is placed in granary, then erects feed belt conveyor between grain unloading device and cloth device outside storehouse, the feed end of transfer conveyor 3 is opposite to the feed end of cloth conveyor 2, so that grain reaches the feed end of cloth conveyor 2 through transfer conveyor 3, and finally grain distribution is carried out through cloth conveyor 2.In the cloth process, cloth conveyor 2 can rotate in horizontal direction around rotary mechanism 5 under the action of hydraulic motor 7, can rotate in vertical plane under the push-pull action of telescopic link 22, while transfer conveyor 3 is not moved, so it can keep continuous feeding and carry out wide range distribution without moving cloth device, thereby reduce the moving frequency of cloth device and feed belt conveyor, can effectively improve the efficiency of grain into storehouse, reduce the labor intensity of worker and energy consumption.

[0030] Among them, rack 1 is as the load main body, its structural form and structural strength need to meet the stability of equipment distribution, avoid equipment to overturn, simultaneously its structural size should be adapted to the arrangement interval spacing of ordinary flat-roofed granary, ensure that rack 1 can move in the interval space of flat-roofed granary on ground.The walking mechanism 4 can adopt the form such as gyro wheel or track, utilize motor to drive, both have advantages and disadvantages, gyro wheel moves more flexible, and the stability of track is better, thus, when conveying capacity is smaller, gyro wheel can be used, when conveying capacity is larger, track is used.In addition, walking mechanism 4 can run through remote control, improve the safety of operation, also avoid the influence of dust on the health of worker.

[0031] In order to increase the distribution range of the distribution device, the distribution conveyor 2 can be preferably an extendable belt conveyor, and the extension range can be designed according to the anti-overturning capacity of the equipment, the rotation range of the distribution conveyor 2 and the grain loading requirement. Preferably, when the distribution device is located on the central axis of the grain bin, the length of the distribution conveyor 2 can meet the requirement of distributing the grain to the grain bin areas on both sides, so that only the distribution device needs to move along the central axis of the grain bin during the distribution process, and the moving frequency of the distribution device and the feeding belt conveyor can be further reduced.

[0032] Since the base 21 and the rotating mechanism 5 are arranged between the distribution conveyor 2 and the frame 1, the height of the distribution conveyor 2 is relatively high, and in order to meet the butt joint requirement with the distribution conveyor 2, the transfer conveyor 3 is preferably an inclined belt conveyor or a scraper elevator, and the feeding end of the transfer conveyor 3 is directly arranged on the frame 1, so that the feeding belt conveyor which is butt jointed with the feeding end of the transfer conveyor 3 from outside the grain bin does not need to be arranged at a high position, and the stability of the installation and grain receiving of the transfer conveyor 3 can be ensured. In addition, in order to facilitate the butt joint of the grain between the transfer conveyor 3 and the distribution conveyor 2, a receiving hopper can be arranged at the feeding end of the transfer conveyor 3 and the distribution conveyor 2, and a discharging hopper is arranged at the discharging end of the transfer conveyor 3, and when the distribution conveyor 2 is in a horizontal state, the discharging hopper, the receiving hopper and the axis of the rotating mechanism 5 are coaxial, so that the discharging end of the transfer conveyor 3 can be always butt jointed with the feeding end of the distribution conveyor 2 when the distribution conveyor 2 rotates.

[0033] For the rotating mechanism 5, in order to ensure the structural stability and facilitate the installation of the equipment, the rotating mechanism 5 is preferably a flange bearing. In order to facilitate the installation of the gear disc 51, the gear disc 51 can be processed with a through hole corresponding to the flange bearing, and is coaxially arranged between the flange bearing and the base 21 through the through hole.

[0034] For the hydraulic motor 7, the axial piston motor is preferred in the utility model, because the axial piston motor has a high torque and a low rotation speed, and can meet the requirement of the driving force and the rotation accuracy of the distribution conveyor 2.

[0035] In order to improve the anti-overturning capacity of the equipment, the base 21 of the distribution conveyor 2 is provided with a counterweight 25 away from one end of the telescopic rod 22.

[0036] In addition, as shown in Figure 2 , Figure 6 and Figure 7As shown, the rack 1 is provided with a limiting block 11 on each side of the rotary mechanism 5, and the limiting block 11 is provided with a distance sensor 12 on the side facing the rear end of the rack 1, and the bottom of the base 21 is provided with a limiting plate 26; taking the front end of the cloth conveyor 2 as a reference, when the cloth conveyor 2 is rotated by 90°, the limiting plate 26 will approach the distance sensor 12 on the limiting block 11 on one side of the rack 1, and the cloth conveyor 2 will stop rotating under the triggering of the distance sensor 12. In this way, the cloth conveyor 2 can be controlled to rotate within a range of 180°, meeting the cloth requirements, and at the same time, the device can be protected, avoiding the device from overturning due to the cloth conveyor 2 rotating too much.

[0037] In the cloth conveying process, in order to realize 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 8 In order to realize the electromechanical control and automatic cloth of the entire device, the rack 1 is provided with an electric control cabinet 9 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 reception of the collision sensor 22 and the grain surface height sensor 23. Among them, the collision sensor 22, the grain surface height sensor 23 and the distance sensor are all existing mature products, and the control system of the electric control cabinet 9 is also an existing technology, and the present application only needs to purchase suitable existing products according to the demand, and the specific control and detection process is not described.

[0038] The preferred working process of the distributing device is as follows: the device is operated to a predetermined position, before distribution, the hydraulic system 8 controls the hydraulic motor 7 and the telescopic rod 22 through the electric control cabinet 9 to adjust the horizontal angle and the pitch angle of the distributing conveyor 2, and to adjust the extension length of the distributing conveyor 2, so that the discharge end of the distributing conveyor 2 reaches the predetermined distribution point, then a feeding belt conveyor is erected between the grain unloading device outside the warehouse and the distributing device, the feeding belt conveyor is connected with the feeding end of the transfer conveyor 3, after the above work is completed, the distribution work is started. During the distribution process, the anti-collision sensor 22 is used for real-time monitoring to avoid collision between the distributing conveyor 2 and the wall surface in the warehouse, the grain surface height detection sensor 23 is used for real-time monitoring of the grain surface height, the signal is fed back to the control center in the electric control cabinet 9, and the height and length of the distributing conveyor 2 are adjusted synchronously, so that the relative height between the grain throwing position of the distributing conveyor 2 and the grain surface is always kept consistent, thereby effectively reducing the grain breakage rate, avoiding the classification phenomenon between grains due to the difference in quality and size, and being beneficial to sampling and storage work. When the grain surface height at the distribution point reaches the predetermined position, the control center sends an instruction to the hydraulic motor 7 and the telescopic rod 22 according to the feedback signal to control the rotation angle of the distributing conveyor 2, so that the discharge end of the distributing conveyor 2 reaches the next distribution point, until the distribution in the range of 180° in front of the device is completed. Then the device is stopped, moved to the next predetermined position, and the external feeding belt conveyor is adjusted synchronously, and the distribution is continued until the distribution work of the entire warehouse is completed.
