Description
Technical Field
[0001] The utility model relates to the technical field of grain storage, in particular to an environmentally friendly electric grain releasing device. Background Art
[0002] In the prior art, a grain discharge port is provided on the side wall of the granary, and an electric control valve and a downward inclined grain discharge pipe are usually provided at the grain discharge port, and rice grains can be discharged from the granary to the grain transport vehicle by opening the electric control valve. However, this technology has some problems and drawbacks.
[0003] First, because the height of the grain trucks is inconsistent, while the height of the grain discharge pipe is fixed, there is often a distance between the grain discharge pipe and the grain truck. This distance will cause dust to be raised when the rice falls on the grain truck, polluting the environment.
[0004] Secondly, when rice falls on the grain truck, it will form a local grain cone, which will cause uneven distribution of rice on the truck, reduce the space utilization of the truck, and require the transporters to flatten the grain cone. However, in order to evenly distribute the rice on the truck, the transporters often need to frequently control the electric control valves, adjust the position of the truck, and other operations, which is labor-intensive and occupies a lot of human resources. In addition, the tediousness and repetitiveness of manual operations also reduce work efficiency and increase operation time.
[0005] Based on this, it is necessary to study an environmentally friendly electric grain releasing device. Utility Model Content

DETAILED DESCRIPTION
[0042] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:
[0043] The present embodiment aims to provide an environmentally friendly electric grain releasing device, which is mainly used for releasing grain in a granary 1 , in order to solve the problem that the existing grain releasing device is prone to generate dust and forms grain cones and uneven laying when releasing grain.
[0044] An environmentally friendly electric grain releasing device, such as Figure 1 , including a granary 1, a grain discharge cylinder 2, an electric control telescopic cylinder 3 and a rotating material distribution mechanism 4; a grain discharge port is arranged on the side wall of the granary 1, and a downwardly inclined grain discharge cylinder 2 and an electric control valve for controlling the opening and closing of the grain discharge port are arranged at the grain discharge port. Since the height of the grain discharge port is usually high, a ladder capable of reaching the grain discharge port is fixed on the side wall of the granary 1, and an operating platform 12 is set up at the grain discharge port for placing and operating the electric control valve. The grain discharge cylinder 2 is fixed on the outer wall of the granary 1 at an angle downward, and the upper end of the grain discharge cylinder 2 is connected to the grain discharge port of the granary 1.
[0045] The upper end of the electrically-controlled telescopic cylinder 3 is fixedly connected to the lower end of the grain discharge cylinder 2. The electrically-controlled telescopic cylinder 3 is vertically distributed and connected to the grain discharge cylinder 2. The electrically-controlled telescopic sleeve is mainly used to adjust the height of the lower end of the electrically-controlled telescopic cylinder 3, which is used to adapt to grain trucks of different heights and to coordinate with the increasing material level on the grain truck.
[0046] In this embodiment, Figure 1 and Figure 2The electric control telescopic cylinder 3 includes an upper cylinder 301, a lower cylinder 302, a sling 303 and a winch 304; the upper cylinder 301 is fixedly connected to the grain discharge cylinder 2, the lower cylinder 302 is slidably mounted on the upper cylinder 301 and fixedly connected to the fixed frame 5; the winch 304 is arranged on the outer wall of the silo and is located above the lower cylinder 302; the left and right sides of the lower cylinder 302 are fixed with lifting rings 305, one end of the sling 303 is divided into two strands and is respectively fixedly connected to the lifting rings 305 on both sides of the lower cylinder 302, and the other end is wound on the winch 304, and the lower cylinder 302 slides up and down on the upper cylinder 301 and maintains its position through the retracting and releasing line of the winch 304. In this embodiment, the winch 304 cable lifting mechanism is used to control the up and down movement of the lower cylinder 302, so as to realize the functional effect of the electric control telescopic cylinder 3. In other embodiments, it can also be realized by a screw nut mechanism, a cylinder, etc.
[0047] In order to optimize the force on the sling 303 and limit the position of the sling 303, guide rings 306 for the sling 303 to pass through are fixed on the upper cylinder 301 and the discharge cylinder, wherein the guide ring 306 on the upper cylinder 301 corresponds to the upper and lower positions of the ring 305, so that the sling 303 can reduce the lateral force when lifting the lower cylinder 302.
[0048] like Figures 3 to 6 The rotating material distribution mechanism 4 includes a fixed frame 5, a rotating drum 6, a rotating shaft 7 and a speed regulating motor 8; the upper end of the fixed frame 5 is fixedly connected to the lower end of the electric control telescopic cylinder 3; the fixed frame 5 includes an upper plate 501, a lower plate 502 and a support column 503; the upper plate 501 is fixedly connected to the lower end of the electric control telescopic cylinder 3, and a avoidance hole 504 connecting the electric control telescopic cylinder 3 and the rotating drum 6 is opened in the middle of the upper plate 501; the upper plate 501 and the lower plate 502 are fixedly connected by the support column 503.
[0049] The rotating drum 6 is rotatably disposed in the middle of the fixed frame 5, that is, the rotating drum 6 is rotatably disposed between the upper plate 501 and the lower plate 502; Figure 4 The rotating drum 6 has a material distributing cavity 601 with an upper opening, the material distributing cavity 601 corresponds to and is connected with the upper and lower positions of the lower end of the electric-controlled telescopic cylinder 3, and the center of the material distributing cavity 601 is vertically fixedly connected with a rotating shaft 7.
[0050] The bottom circumference of the distribution cavity 601 is provided with a plurality of distribution holes 602 connected to the outside. Under the centrifugal action of the drum 6, the rice grains entering the drum 6 will be scattered on the side of the distribution cavity 601 and scattered onto the grain transport vehicle through the circumference of the distribution holes 602, thereby avoiding accumulation on the grain transport vehicle and forming a grain cone.
[0051] The speed regulating motor 8 is fixed on the fixing frame 5 and is in driving connection with the rotating shaft 7. The speed regulating motor 8 is installed on the lower surface of the lower plate 502. The lower plate 502 is provided with a through hole for the motor shaft of the speed regulating motor 8 to pass through. The motor shaft passes through the lower plate 502 downward and upward and is in driving connection with the rotating shaft 7. The speed of the speed regulating motor 8 can be adjusted. By adjusting the speed, the scattering diameter of the rice grains can be adjusted, thereby controlling the scattering position of the rice grains, so that the rice grains can be evenly arranged in the grain transport vehicle.
[0052] In order to further optimize the fixed relationship between the rotating shaft 7 and the rotating drum 6, in this embodiment, a shaft sleeve 10 with a lower opening is fixedly arranged at the center of the fabric cavity 601, and the shaft sleeve 10 is fixedly sleeved on the rotating shaft 7, and the top of the rotating shaft 7 abuts against the top inside the shaft sleeve 10, so that the rotating drum 6 can maintain a more stable fixed relationship with the rotating shaft 7. In order to ensure that the rotating drum 6 can rotate smoothly, four universal wheels 13 are arranged on the bottom circumference of the rotating drum 6, and the wheel surface of the universal wheel 13 abuts against the upper surface of the lower plate 502. When the rotating drum 6 rotates, the universal wheel 13 steps on the lower plate 502 to move, providing a stable support for the rotating drum 6.
[0053] In order to facilitate the rice grains to flow to the discharge hole and prevent the rice grains from staying in the material distribution cavity 601 when the rotating drum 6 rotates at a low speed, a conical material guide plate 9 is arranged around the rotating shaft 7, and the bottom of the material guide plate 9 contacts the bottom of the material distribution cavity 601 to form a flow guide for the rice grains. Since the shaft sleeve 10 is provided in this embodiment, the material guide plate 9 is fixed around the shaft sleeve 10.
[0054] Due to the centrifugal action of the drum 6, the rice in the cloth cavity 601 will be centrifugally separated from the dust. In order to collect the dust and avoid dust pollution, a dust collection bin 603 is formed between the guide plate 9 and the bottom of the cloth cavity 601. The surface of the guide plate 9 is provided with a dust collection hole 901 connecting the cloth cavity 601 and the dust collection chamber. The surface of the dust collection hole 901 is detachably fixed with a filter screen. The dust collection hole 901 only allows dust to pass through and intercepts the rice. The shaft sleeve 10 is fixedly provided with an impeller 11, which is located in the dust collection bin 603. The impeller 11 rotates with the rotation of the shaft 7, forming a negative pressure adsorption effect in the dust collection bin 603.
[0055] A dust box 14 is detachably installed at the bottom of the rotating drum 6, and a dust collecting hole 604 connecting the dust suction chamber and the dust collecting box 14 is provided at the bottom of the cloth cavity 601. The dust collecting hole 604 is distributed below the impeller 11, and an air vent connected to the outside is provided in the dust collecting box 14, thereby forming a wind circulation. The air vent allows air to flow and intercept dust. Under the action of the impeller 11, the dust will be absorbed into the dust suction bin 603, and then discharged into the dust collecting box 14 to collect the dust.
[0056] To facilitate manual operation, the winch 304 is arranged on the operating platform 12 and is control-connected to the operating platform 12, and the speed regulating motor 8 is also control-connected to the operating platform 12, so that the grain transport workers can operate the electric-controlled valve, the electric-controlled telescopic cylinder 3 and the rotating material-distributing mechanism 4 on the operating platform 12 at the same time with a better field of vision.
[0057] The specific usage method of this embodiment is: the grain transport worker parks the grain transport vehicle under the rotating material distribution mechanism 4, and the grain transport worker goes to the operating platform 12; operates the winch 304 to adjust the upper and lower positions of the rotating material distribution mechanism 4; opens the electric control valve of the grain outlet and the speed regulating motor 8 of the rotating material distribution mechanism 4; adjusts the speed of the speed regulating motor 8 according to the distribution of rice in the grain transport vehicle, so that the rice in the grain transport vehicle is evenly arranged; operates the winch 304 to adjust the upper and lower positions of the rotating material distribution mechanism 4 according to the material level height in the grain transport vehicle; and closes the electric control valve and the speed regulating motor 8 after the grain transport vehicle is full.
