Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain storage, and particularly to a grain inlet of a granary. Background Art
[0002] During the grain warehousing operation of a granary, a manual or automatic shutter is generally installed at the grain inlet. The shutter communicates with the head of the conveying equipment on the granary top. Since the conveying equipment on the granary top is placed in the open air, rainwater will flow into the upper part of the grain inlet shutter from the head of the equipment. If the sealing performance of the shutter is not good, there will be a potential safety hazard of rainwater leaking into the granary. In addition, the airtightness of the granary is the key to ensuring the nitrogen filling effect. After the applicant's inspection of the actual airtightness of the granary, the lower part of the grain inlet shutter is the main air leakage point. Limited by the structural problems of the shutter itself, it is difficult to have a substantial treatment effect on this air leakage point. This problem poses a great challenge to effectively maintaining the nitrogen concentration and ensuring the nitrogen filling effect. At the same time, when the MEC equipment is idling and running periodically, a certain amount of dust will accumulate above the grain inlet shutter. If it is not cleaned in time, the dust is likely to form a hard crust and breed pests after being damp, thus bringing a potential safety hazard of cross-infection in grain storage. Content of the Utility Model
[0003] The purpose of the utility model is to provide a grain inlet of a granary, which has the effects of canceling the shutter structure, having good airtightness and anti-leakage performance at the grain inlet during static grain storage, separating the conveying equipment from the grain inlet when not in operation, and avoiding the potential safety hazard of rainwater leaking into the granary.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions: A grain inlet of a granary includes a grain inlet, a sealing plate detachably connected to the grain inlet, and a telescopic chute pipe located above the grain inlet. The upper end of the telescopic chute pipe is used to be connected with the conveying equipment, and the lower end is used to be connected with the grain inlet.
[0005] By adopting the above technical solutions, the utility model cancels the shutter structure. When the grain inlet operation is not carried out, the grain inlet is sealed with the sealing plate, and the airtightness and anti-leakage performance at the grain inlet of the granary are significantly improved. At the same time, the telescopic chute pipe is located above the sealing plate and is effectively isolated from the sealing plate in space, which is convenient for cleaning the dust accumulated on the sealing plate and thoroughly solves the problem of pest breeding caused by the dust accumulation phenomenon.
[0006] When the grain inlet operation is carried out, the staff manually disassembles the sealing plate, stretches the telescopic chute pipe downward to make it longer, and then connects the lower end of the telescopic chute pipe to the grain inlet to carry out the grain inlet operation.
[0007] The further setting of the utility model is that the sealing plate and the grain inlet are detachably connected through connecting bolts and connecting nuts.
[0008] A further setting of the present utility model is that: the lower end of the telescopic chute pipe is connected to the grain inlet after removing the disassembly sealing plate through connecting bolts and connecting nuts.
[0009] A further setting of the present utility model is that: the telescopic chute pipe includes an inner pipe, an outer pipe sleeved on the inner pipe, and a locking assembly. The locking assembly includes a locking hook located on the inner pipe and a locking frame hinged to the outer pipe, and the locking frame hooks the locking hook.
[0010] By adopting the above technical solution, when the locking frame hooks the locking hook, the positions of the inner pipe and the outer pipe are fixed, and at this time the telescopic chute pipe is in a contracted state. When the locking frame leaves the locking hook, the outer pipe can move relative to the inner pipe, and at this time the telescopic chute pipe can be lengthened or shortened.
[0011] A further setting of the present utility model is that: the locking assembly includes an adjusting handle provided on the locking frame.
[0012] By adopting the above technical solution, it is convenient for the staff to adjust the position of the locking frame.
[0013] A further setting of the present utility model is that: the number of the locking assemblies is multiple.
[0014] A further setting of the present utility model is that: the cross-section of the inner pipe and the cross-section of the outer pipe are both rectangular.
[0015] By adopting the above technical solution, relative rotation is avoided during the relative movement of the outer pipe and the inner pipe.
[0016] A further setting of the present utility model is that: a transparent bag body is provided at the lower end of the telescopic chute pipe, and a plurality of magnets are fixed to the transparent bag body, and the magnets are adsorbed on the lower end of the telescopic chute pipe.
[0017] By adopting the above technical solution, the conveying equipment generally corresponds to the grain inlets of several grain bins, and through internal devices such as three-way valves, the grain inlet operation of different grain bin inlets is realized. If the device has poor sealing, some grain will leak to the grain inlets of the grain bins where the grain inlet operation is not carried out. If a gate structure is installed at the grain inlet, the leaked grain will be blocked by the gate and will not fall outside the grain bin. However, in the present utility model, the gate structure is cancelled, and the lower end of the telescopic chute pipe is separated from the grain inlet, and the grain will fall outside the grain bin, and it is very troublesome to clean and collect it again, and even the grain will be contaminated.
[0018] In view of this, when the grain inlet operation is not carried out, the transparent bag body is adsorbed and fixed at the lower end of the telescopic chute pipe by the magnets. If the staff observes that there is grain in the transparent bag body, it means that when the conveying equipment conducts the grain inlet operation for other grain bins, grain leaks over, and it is necessary to check the sealing performance of the internal device of the conveying equipment. The transparent bag body can also collect the leaked grain.
[0019] When grain feeding operation is required, the staff remove the magnet and the transparent bag body in advance.
[0020] A further setting of the present utility model is that: the sealing plate is provided with a holding handle.
[0021] By adopting the above technical solution, when disassembling the sealing plate, it is convenient for the staff to hold and transfer the sealing plate.
[0022] A further setting of the present utility model is that: the grain bin is a shallow silo.
[0023] The beneficial effects of the present utility model are:
[0024] 1. For the shallow silo for static storage of the present utility model, the manual or automatic gate structure is cancelled, and a telescopic chute is directly adopted instead. For the silo for static storage, the operation frequency is relatively low, and there is sufficient time to disassemble and install the connection between the telescopic chute and the grain inlet. Moreover, in the daily static storage of the warehouse, the advantage of good airtightness can be more effectively exerted.
[0025] 2. After the grain inlet is transformed in the present utility model, the opening and closing state of the grain inlet can be visually shown during the warehousing operation, and the phenomenon of misloading into the wrong silo due to misjudging the state of the manual gate of the grain inlet can be effectively avoided.
[0026] 3. The present utility model cancels the gate structure. When the grain feeding operation is not carried out, a sealing plate is used to seal the grain inlet, and the airtightness and anti-leakage performance at the grain inlet of the grain bin are significantly improved. At the same time, the telescopic chute is located above the sealing plate and is effectively isolated from the sealing plate in space, which is convenient for cleaning the dust and dirt on the sealing plate, and completely solves the problem of insect breeding caused by the phenomenon of dust and dirt accumulation.
