Description

[Detailed description of the invention] [Industrial application field] The present invention mainly relates to a device for cleaning root vegetables such as sweet potatoes, radish, carrots, etc., and in particular, the inside of the cleaning drum of the cleaning device has a highly wear-resistant material. A flocked sheet made of synthetic resin is attached to enhance the cleaning effect of the object to be washed, and also to provide a cushioning effect to prevent the object to be damaged from colliding with the inside of the drum during cleaning.

[Prior Art] As is well known, root vegetables have foreign substances such as dirt attached to their surfaces immediately after harvesting, so it is important for producers to wash and remove these foreign substances before shipping the harvested crops. Always. As for the device related to this cleaning, the applicant's earlier application, Utility Model Publication No. 52-51185,
No. 58-4468, etc., in which a cleaning drum is fixed or rotatably mounted horizontally on a base, and a rotating shaft to which a blade made of sponge or the like is fixed is inserted through the drum, and the blade or The blades and drum are rotated to clean root vegetables placed in the drum.

[Problems to be solved by the invention] By the way, each of the above-mentioned devices has a sponge or brush attached to the inner surface of the drum in order to prevent root vegetables from being damaged during cleaning and to improve the cleaning effect. However, because the objects to be cleaned are relatively hard, such as potatoes, radishes, and carrots, when each of the above devices is used for a long period of time, the sponge etc. will become abrasive and will no longer function as a cushion, causing damage to the objects to be cleaned. Damage may have occurred. In this case, the sponge or brush must be replaced, but this work is technically difficult and requires a lot of effort for the user to perform. Improvements were desired.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned drawbacks of the conventional type, and in order to provide a new root vegetable cleaning device that can withstand long-term use. By attaching a water-permeable flocked sheet made of synthetic resin to the inner surface of the cleaning drum via a sponge, it not only has a cushioning effect, but also has a cushioning effect.
The aim is to further enhance the cleaning effect on objects to be cleaned by using the flocked sheet.

[Example] Hereinafter, the present invention will be specifically explained with reference to the drawings. What is shown in FIG. 1 shows a first embodiment of the present invention. Reference numeral 1 denotes a base that holds a cleaning drum 2, the front half of which is provided with a supply table 3 for supplying the object to be cleaned P into the drum, and the rear half of which is provided with a base for cleaning that is continuous with the supply table 3. Place drum 2 horizontally. The drum 2 is a hollow cylindrical body, and has an input port 4 for the object to be cleaned on one end surface (on the supply table side) and a discharge port 5 on the other end surface. Further, as shown in FIG. 3, a sponge 24 is attached to the inner wall of the drum 2 using adhesive.
Water permeable flocked sheet made of synthetic resin on the top surface 6
is also attached using adhesive. Also drum 2
Water withdrawal pipes 7 and 8 are provided at both ends as necessary.

On the other hand, a frame 9 is attached above the cleaning drum 2 integrally with the base 1, and a driving means 10 consisting of a rotational transmission member such as a motor and a belt, which will be described later, is disposed on the frame 9, and the drum 2 is rotatably held by a pair of front and rear rollers 11 and the like. A rotary shaft 12 that rotates in the same direction as the drum is installed within the drum 2, and vanes 13 made of an elastic material such as a sponge plate are radially attached to the rotary shaft 12.

Next, a device for rotating the cleaning drum 2 and the rotating shaft 12 will be explained. As shown in FIG.
A guide rail 14 serving as a track is provided, and an engaging groove 16 for a drive belt 15 is provided parallel to one of the guide rails 14. Further, a pulley 17 is attached to the frame 6, and a belt 15 for driving the drum 2 is stretched between the pulley 17 and the engagement groove 16. It is connected to the output shaft of the motor 20 via.

On the other hand, the rotating shaft 12 has a pulley 2 on its end side.
1. Pulleys 22 are installed on the frame 9 above the pulleys 21, and a shaft rotation belt 23 is stretched between these pulleys.

Although not shown in the drawings, a leg length adjustment mechanism is incorporated into the legs of the base 1, which allows the cleaning drum 2 to be tilted at an appropriate angle. be.

Next, a method of using the cleaning device according to the present invention having the above-mentioned configuration will be explained. First, while pouring a predetermined amount of cleaning water into the drum 2 from the water withdrawal pipes 7 and 8, the motor 20 is turned on to rotate the cleaning drum 2 and the rotating shaft 12. Next, when the object to be cleaned P is put into the inlet of the cleaning drum 2 from the supply stand 3, the object to be cleaned P is transferred to the rotary blade 12.
The water-permeable flocked sheet 6 is caressed by the flocked flocks 6' of the flocked sheet 6, and mud and the like on the surface are washed away with water.
Moreover, even if the object to be cleaned P rolls within the drum 2 and crushes the bristles of the flocked sheet,
The sponge 24 containing water on the lower surface acts as a cushion, and the object to be cleaned P does not collide directly with the inner wall of the drum. In this way, the object to be cleaned P moves along the slope of the cleaning drum 2 in the direction of the discharge port 5,
At the time of discharge, the surface is cleaned and passed through the discharge port 5.
taken from.

By the way, in each of the above embodiments, not only the rotary blade installed in the cleaning drum but also the cleaning drum is rotated, but the present invention is applied to a cleaning device in which the drum is fixed and only the rotary blade rotates. Of course, there is no problem.

[Effects of the invention] As mentioned above, in the washing machine of the invention, a highly wear-resistant synthetic resin flocked sheet is attached to the inside of the washing drum through a sponge, so it provides a solid covering during washing. The shock generated when the object to be washed collides is absorbed not only by the bristles of the flocked sheet but also by the sponge, so that the object to be washed is not damaged and the object to be washed does not collide with the inner wall of the drum. No collision noise is generated. Furthermore, the cleaning effect can be enhanced due to the sponge's high water retention properties.

In addition, the synthetic resin flocked sheet has less wear compared to brushes made of silica or the like, and can withstand long-term use.
