Description

Technical Field

[0001] The utility model relates to the technical field of grain shredders, in particular to a high-efficiency grain shredder. Background Art

[0002] Grain scraper, also known as grain scraper, is an agricultural machinery used for bulk grain collection and loading, grain storage, and can be used in combination with conveyors for stacking and loading. Currently, it is mostly used for loading materials packed in ton bags. Ton bags are also called ton bags and space bags, which are a popular name for container bags. Because the goods loaded in container bags are generally 1 ton, they are commonly called ton bags. It is a flexible transport packaging container, widely used for the transportation and packaging of powdered, granular, and blocky items such as food, grains, medicines, chemicals, and minerals. Developed countries generally use container bags as packaging products for transportation and warehousing.

[0003] The power equipment of existing ton bag bulk grain pickers is usually driven by an electric motor, which transmits the drive shaft and the active roller of the conveyor body through belts and pulleys. However, after long-term use, the transmission structure will also have friction loss, which will reduce the transmission efficiency. That is, the transmission efficiency is reduced due to the force loss in the mechanical transmission process, and the maintenance cost will also increase.

[0004] Energy loss in a mechanical transmission system can cause power loss. Power loss refers to the loss of efficiency of the system due to excessive power consumption. For example, in a gear transmission system, the meshing of the gears causes noise and vibration and causes power loss, and the driving device acting on the output mechanism is also accompanied by power loss. These power losses will increase the energy consumption of the system and may affect the stability of the transmission system. Therefore, reducing power loss is one of the important ways to improve the efficiency of mechanical transmission systems.

[0005] Transmission efficiency is an important indicator to measure the performance of mechanical transmission systems. In the actual transmission process, there are various energy losses, such as transmission loss, friction loss and internal friction loss of mechanical materials. These energy losses will reduce the efficiency of transmission. These power losses will not only increase the energy consumption of the system, but also may affect the stability of the transmission system.

[0006] Therefore, in order to improve the transmission efficiency and ensure the stability of the transmission system, the power equipment and active roller transmission method of the conveyor body are optimized to reduce power losses, so as to better stabilize the conveying efficiency of the scraper conveyor materials. In addition, on the basis of the existing power equipment and being able to ensure the force transmission effect, achieving the power amplification effect is an urgent problem to be solved.

[0025] like Figures 1 to 5 As shown: A high-efficiency grain scraper includes a conveyor body 1, a feed hopper 17 and a driving mechanism. The conveyor body 1 is placed obliquely, and a support frame 14 is fixedly connected to the bottom of the conveyor body 1, and a support wheel 15 is rotatably connected to the bottom of the support frame 14. A feed head 16 is fixedly connected to the side of the conveyor body 1 close to the ground, and the interior of the conveyor body 1 is connected to the interior of the feed head 16. The feed hopper 17 is arranged on one side of the feed head 16, and the feed hopper 17 is connected to the feed head 16; a guardrail 18 is fixedly connected to the outside of the feed hopper 17, and a sling 22 for placing tools for cleaning materials is bolted between the guardrail 18 and the feed hopper 17.

[0026] An active roller and a driven roller are rotatably connected in the conveyor body 1, and the driving mechanism includes a motor 2, a first pulley 4, a second pulley 5 and a force-increasing unit. The motor 2 is fixedly connected to the inclined upper surface of the conveyor body 1, and one end of the active roller is fixedly connected to a driven shaft 23, which passes through the conveyor body 1 and is rotatably connected to the conveyor body 1. The output shaft of the motor 2 is fixedly connected to a driving shaft 6, and the driving shaft 6 and the driven shaft 23 are respectively fixedly connected to the first pulley 4 and the second pulley 5, and a belt 7 is transmission-connected between the first pulley 4 and the second pulley 5, wherein the diameter of the first pulley 4 and the second pulley 5 is 110 mm; the active roller and the driven roller are respectively fixedly connected to sprockets, and a chain 20 is transmission-connected between the sprockets, and a number of scrapers 19 are fixedly connected to the chain 20, and the conveyor body 1 and the internal structure are the same as those of a 200-type scraper conveyor grain throwing machine.

[0027] The force amplification unit includes two connecting shafts 9, two first pry bars 10 and two second pry bars 11. The two connecting shafts 9, the two first pry bars 10 and the two second pry bars 11 are respectively arranged on both sides of the driving shaft 6 and are symmetrical about the center of the driving shaft 6. Each connecting shaft 9 is fixedly connected to the driving shaft 6. Each first pry bar 10 and the second pry bar 11 are respectively hinged with a hinge shaft 13. Each hinge shaft 13 is fixedly connected to the surface of the first pulley 4. The long lever arm of each first pry bar 10 is rotatably connected to the connecting shaft 9. One end of the short lever arm of each first pry bar 10 is against the side of the long lever arm of the second pry bar 11. The end of one end of the short lever arm of each second pry bar 11 is fixedly connected to the first pulley 4 with a fixed shaft 12.

[0028] A protective cover 3 is bolted to one side of the conveyor body 1, and the drive shaft 6, the first pulley 4, the belt 7, the driven shaft 23 and the second pulley 5 are all located in the protective cover 3. An electric box 21 is fixedly connected to one side of the conveyor body 1, and the control end in the electric box 21 is electrically connected to the motor 2. A discharge pipe 8 is fixedly connected to one end of the conveyor body 1 away from the feed head 16, and a cloth bag for discharge is provided at the end of the discharge pipe 8.

[0029] The implementation method of this embodiment is as follows: when in use, the vehicle loaded with materials is parked under the discharge pipe 8 of the conveyor body 1 to prepare for receiving materials, and the motor 2 is started. The motor 2 drives the driving shaft 6 and the first pulley 4 to rotate. Under the transmission action of the belt 7, the driven shaft 23 and the second pulley 5 rotate synchronously, and the driven shaft 23 drives the active roller to rotate. The active roller drives the chain 20 to transmit and then drives the driven roller to rotate. The scraper 19 follows the chain 20 to gradually transmit. The forklift lifts the ton bag filled with materials to the top of the feed hopper 17, opens the discharge port under the ton bag, and allows the materials in the ton bag to fall into the feed hopper 17. After entering the feed hopper 17, the materials fall to the feed head 16 at the bottom, and the scraper 19 gradually transports the materials to the discharge pipe 8 of the conveyor body 1, and falls into the vehicle from the discharge pipe 8 to gradually complete the loading.

[0030] During the rotation of the motor 2, if the driving shaft 6 drives the two connecting shafts 9 to rotate in the clockwise direction, the driving shaft 6 also drives the first pulley 4 to rotate in the clockwise direction, and the connecting shaft 9 pulls the first pry bar 10 to rotate in the counterclockwise direction. Under the action of the hinge shaft 13 of the first pry bar 10, according to the lever principle, the first pry bar 10 instantly generates centrifugal force under the traction of the connecting shaft 9. Therefore, one end of the long lever arm of the first pry bar 10 close to the second pry bar 11 swings toward the end of the long lever arm of the second pry bar 11, and generates a displacement trend or even a small displacement. According to the lever principle, the second pry bar 1 The long lever arm of 1 pries the short lever arm of the second lever 11, and the second lever 11 generates a rotation tendency under the swing of the first lever 10, and the direction of the rotation tendency of the second lever 11 is opposite to the rotation direction of the first lever 10, that is, the rotation direction of the second lever 11 is clockwise, thereby, the fixed shaft 12 connected to the second lever 11 drives the first pulley 4 to rotate in the clockwise direction, and the traction force of the fixed shaft 12 is the same as the rotation direction of the first pulley 4 driven by the driving shaft 6, so that the first pulley 4 is subjected to the driving force and the traction force of the two second levers 11 under the action of the driving shaft 6.

[0031] Under the action of the two force-saving levers, the first pry bar 10 and the second pry bar 11, if the initial driving force is F1, then after the force transmitted by the first pry bar 10 and the instantaneous centrifugal force applied to the first pry bar 10, the force applied to the second pry bar 11 from the first pry bar 10 is F2, and at this time F2>F1. Similarly, after the force transmitted by the second pry bar 11, the final force acting on the first pulley 4 by the fixed shaft 12 is F3, and at this time F3>F2. The force F3 applied to the first pulley 4 is naturally greater than the initial driving force F1 of the motor 2 and the drive shaft 6. Therefore, the original driving force of the motor 2 on the drive shaft 6 and the first pulley 4 not only reduces the force loss but also achieves the effect of force amplification.

[0032] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
