Description

Feeding device with automatic cleaning unit

The present invention relates to a feeding device, and more particularly to a feeding device having an automatic cleaning unit that can automatically remove accumulated material.

The existing grain dryer comprises a drying chamber for drying the grain, the grain is circulated through the pipe of the grain dryer, and repeatedly enters the drying chamber for drying until the water content reaches a target value.

The grain dryer further comprises a feeding tube at the top of the drying chamber, and a screw feeding rod disposed in the tube cavity of the feeding tube, and the grain finally enters the feeding tube during the circulation in the pipeline, and the The rotary advancement of the screw feed rod advances in the feed tube and eventually falls back to the drying chamber from a dispensing opening of the feed tube.

Since the feeding tube is disposed substantially in the horizontal direction, the material will be piled up at the bottom of the feeding tube after use, that is, the space between the screw feeding rod and the inner wall surface of the feeding tube, and such accumulation is not possible to be fed by the screw. The rod is pushed and removed, and the continuous accumulation of grain may deteriorate, affecting the quality of the whole batch of grain to be dried; and the feeding tube is located on the top of the dryer. It is conceivable that it is not only quite laborious to manually remove it by hand. Cleaning personnel must also bear a high security risk.

Accordingly, it is an object of the present invention to provide a feed device having an automatic sweeping unit that automatically removes stock.

Accordingly, the present invention has a feeding device for an automatic cleaning unit, which is suitable for being installed in a material drying machine having a drying chamber, and includes a periphery defining a lumen and at least one located at the bottom and communicating the lumen with the drying chamber. a feed pipe of the material discharge port, a screw feed rod disposed in the pipe cavity, and at least one pair of automatic sweeping units disposed at the discharge port, the automatic sweeping unit including a driving mechanism, and one of which is drivable by the driving mechanism The baffle of the discharge opening can be closed open.

The effect of the invention is that when the bottom of the feed pipe is accumulated, the driving mechanism of the automatic sweeping unit can drive the baffle and open the discharge opening, so that the accumulated material can be dropped to the drying through the discharge opening. Chamber and empty the feed tube.

Other features and effects of the present invention will be apparent from the following description of the drawings. FIG. 1 is a view showing a preferred embodiment of the feeding device of the present invention having an automatic cleaning unit installed in a material dryer. 2 is a schematic side view of the preferred embodiment; FIG. 3 is a cross-sectional view along the line III-III of FIG. 2, illustrating a baffle in the preferred embodiment to close a cutout; 4 is a view similar to FIG. 3, illustrating a driving device of the preferred embodiment driving the shutter and opening the cutout.

Referring to Figures 1 to 3, a preferred embodiment of the feeding device of the present invention having an automatic cleaning unit is adapted to be mounted in a material dryer 5 having a drying chamber 51 and including a periphery defining a lumen 11 a feed pipe 1 of the material port 12 and the two material discharge ports 15, a screw feed rod 2 disposed in the pipe cavity 11, a drive unit disposed on the feed pipe 1 and capable of driving the screw feed pipe 2 to rotate around its own axis 3 and 2 are respectively disposed in the automatic cleaning unit 4 of the feed pipe 1.

The feed pipe 1 includes an inner pipe wall 13 and a guide surface 16 that connects the inner pipe wall 13 and the end edges of the discharge ports 15 and is inclined from top to bottom. The lumen 11 is defined by the inner tube wall 13 and the guiding surface 16. The dispensing opening 12 and the cutouts 15 are opened at the bottom of the feeding tube 1 and communicate with the lumen 11 and the drying chamber 51.

The automatic cleaning units 4 are respectively disposed corresponding to the stripping ports 15 and respectively include a driving mechanism 41, a baffle 42 and a corresponding driving device 41 and driving the baffle 42 to be openably closed. The push rod 43 of the feed opening 15 and a bracket 44 extending horizontally from the outer wall of the feed tube 1 and connecting the push rod 43 to the baffle 42 at an obtuse angle.

Each of the baffles 42 includes a pivoting portion 421 pivotally connected to the feeding tube 1 , a follower portion pivotally connected to the push rod 43 and rotatable around the pivoting portion 421 by the push rod 43 422. A cover portion 423 between the pivoting portion 421 and the driven portion 422 for closing the corresponding cutout 15 and a cutout 15 corresponding to the closure portion 423. At the time, the end edge of the discharge opening 15 is pressed to seal the elastic gasket 424 of the discharge opening 15.

Referring to FIG. 2 to FIG. 4, the driving unit 3 can drive the screw feed rod 2 to rotate around its own axis. At this time, the blade 21 on the screw feed rod 2 pushes the material in the tube 11 to advance. The material is dropped into the drying chamber 51 through a dispensing opening 12 opened at the end of the feeding tube 1.

When the material in the feeding tube 1 is deposited on the bottom of the tube 11, the user can control the driving mechanism 41 of the automatic cleaning unit 4 via an electronic control system (not shown) to drive the materials. The push rods 43 respectively push the driven portions 422 of the baffles 42 so that the baffles 42 can be opened and the accumulation in the lumen 11 can be dropped into the drying by the discharge ports 15 In the chamber 51, after the material is removed, the driving mechanism 41 is controlled to contract the push rods 43 to reset the baffles 42 to close the discharge ports 15.

It is worth mentioning that in the present embodiment, the guiding surface 16 of the feeding tube 1 which is inclined downward can ensure that the material is smoothly dropped from the lumen 11 without a residual situation.

It is conceivable to set a different number of the cutouts 15 as required, and to perform the setting of the corresponding number of automatic cleaning units 4, without being limited to the form disclosed in the embodiment, or even to open only one elongated shape. The material port 15 is closed with a plurality of sets of automatic cleaning units 4, and any feasible way to achieve the same effect as the embodiment can be implemented.

In summary, when the bottom of the feeding pipe 1 is accumulated, the driving mechanism 41 of the automatic cleaning unit 4 can be controlled by the electronic control system to automatically drive the baffles 42 and open the receiving ports 15 so that The material is dropped by the discharge ports 15 to empty the accumulated material in the feeding pipe 1, which is convenient and quick. It is easy to make and the mechanism principle is relatively simple, easy to manufacture, use and implement, and the effect of optimizing the drying effect of the material dryer 5 can be achieved, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
