Description

Technical Field

[0001] The utility model relates to the technical field of feed feeding equipment, in particular to a vibration device for a material tower. Background Art

[0002] In farms or breeding farms, feed towers are often used to store a certain amount of feed to provide nutrition for the animals. A receiving hopper is installed at the bottom of the feed tower, and a conveying pipe is set at the bottom of the receiving hopper. A conveying plug chain is installed in the conveying pipe to transport the feed. However, the feed in the feed tower will be affected by factors such as ambient temperature, humidity, and the viscosity of the feed itself, which will cause the feed to clot, hindering the normal flow of the feed.

[0003] In order to prevent the feed from bridging, the feed in the silo needs to be vibrated. The relevant vibration device is installed in the hopper and will bounce up and down with the movement of the conveying plug, thereby hitting and moving the feed up and down to prevent the feed from bridging in the local area. The vibration effect of the relevant vibration device is very limited, the vibration range is small, only about less than 1% of the area, and it can only work when the conveying plug works, and cannot vibrate independently and periodically. In addition, when the vibration device is used, it will rub and collide with the parts of the conveying plug system, which will cause mechanical damage to the parts of the conveying system. Utility Model Content

[0004] In order to overcome the defects of the prior art, a vibration device for a material tower is now provided, which can solve the problems of limited vibration effect, small vibration range, inability to vibrate independently and periodically, and mechanical damage to parts of the conveying plug system.

[0005] In order to achieve the above technical effects, the solution provided by the utility model is to provide a vibration device for a material tower, which includes:

[0006] A vibration shell having a vertical passage formed therein and mounted at the discharge port of the material tower;

[0007] A vibrating screen is installed in the vertical channel in a horizontally movable manner;

[0008] A vibration shaft, wherein the vibration housing is symmetrically provided with a pair of through holes for the vibration shaft to pass through, and the vibration screen is fixed on the vibration shaft;

[0009] Vibration motor, the first end of the vibration shaft is vertically connected to the side wall of the vibration motor.

[0010] Preferably, a first spring is installed between the vibration shaft and the vibration motor, the first spring is sleeved on the vibration shaft, the second end of the vibration shaft is sleeved with a second spring and a limiting sleeve is fixed to the end of the second end.

[0011] Preferably, the first spring and the second spring are both covered with a retractable dust cover, and both ends of the retractable dust cover are fixed to the vibration shaft through a hose clamp. The retractable dust cover can prevent debris from entering and affecting the movement, and prevent workers from contacting and pinching their hands.

[0012] Preferably, the number of the vibration shafts is two, the first ends of the two vibration shafts are commonly connected to the connecting plate, and the vibration motor is connected to the side of the connecting plate away from the vibration shaft. The two vibration shafts can provide better balance. When the vibrating screen is working, the two vibration shafts can ensure that the vibration force is evenly distributed, reducing equipment wear or structural deformation caused by uneven vibration. It can also produce more effective vibration effects, provide better stability, increase the carrying capacity of the vibrating screen, and make maintenance and replacement more convenient. If one shaft has a problem, the other shaft can temporarily maintain the operation of the vibrating screen, thereby reducing downtime.

[0013] Preferably, the connecting plate is provided with two first sleeves corresponding to the two vibration shafts, and the vibration shafts are sleeved in the first sleeves and connected by bolts.

[0014] Preferably, a bearing seat is installed in the through hole, an oil-free bushing is installed in the bearing seat, and the vibration shaft is installed in the oil-free bushing. Since the oil-free bushing does not require lubrication, maintenance work is reduced, and it can also absorb part of the vibration, which helps to reduce the impact of vibration on other parts of the equipment and play a certain shock-absorbing role.

[0015] Preferably, a second sleeve for sleeve mounting of the vibration shaft is provided at the bottom of the vibration screen, and the second sleeve is connected to the vibration shaft by bolts.

[0016] Preferably, the vibration shell is a variable diameter circular tube structure.

[0017] The beneficial effect of the utility model is that a vibration device for a material tower of the utility model is installed at the discharge port of the material tower, and the vibration shaft is vertically connected to the side wall of the vibration motor, that is, the vibration shaft and the motor shaft of the vibration motor are perpendicular to each other. Then when the vibration motor is started, the vibration shaft vibrates and drives the vibration screen to vibrate. At the same time, the vibration motor generates an exciting force. Under the action of the exciting force, the vibration shaft will move left and right, and the vibration screen will move left and right horizontally in the vertical channel in the vibration shell. The left and right movement of the vibration screen realizes the full-range vibration coverage of the material tower, so that all the feed in the material tower can obtain the necessary vibration, and the occurrence of bridging is prevented. The vibration range of the utility model is very large, and more than 95% of the feed in the material tower will produce a vibration effect, with good vibration effect and independent periodic vibration. The feed in the material tower can be vibrated at any time according to needs to prevent feed bridging and agglomeration, and will not cause mechanical damage to the parts of the conveying system.
