Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vegetable washing machine used for washing radish, burdock, etc.

(Prior Art) A plurality of brush rollers are arranged in parallel so as to be rotatably driven, and a pressing plate having brush bristles planted on the lower surface is provided oppositely on the upper surface side of the rollers, and the processed material is transferred by the rollers. There have been conventional vegetable washing machines in which objects are rubbed by the brush bristles of the roller and the pressing plate (for example,
-Refer to Publication No. 16865).

(Problems to be solved by the invention) Conventional vegetable washing machines had the following problems.

In other words, since the brush bristles of the press plate are installed perpendicularly to the plane of the plate, when the press plate moves back and forth in the transfer direction while the object to be processed is being transferred by the brush roller, the pressure is applied. Some of the brush bristles on the plate may be inclined in a direction that obstructs the transfer of the object to be treated, that is, in the opposite direction, and the smooth transfer may be impaired.

In addition, when the object to be cleaned is relatively large, the pressing action of the press plate becomes excessive compared to the transfer force of the object by the brush roller, and the object is smoothly moved between the brush roller and the press plate. Since it does not penetrate, it is necessary to push it in by hand.On the other hand, if the object to be cleaned is relatively small, the pressing action may be insufficient and a sufficient cleaning effect may not be obtained. .

An object of the present invention is to provide a vegetable washing machine that eliminates the above-mentioned problems and enables smooth washing processing.

(Means for Solving the Problems and Their Effects) The present invention is characterized in that the brush bristles of the pressing plate are implanted so as to recede within a certain inclination angle range toward the direction in which the object to be processed is transported. Therefore, when the pressing plate that presses the object from above swings back and forth while the object is being transferred, the bristles of the pressing plate may partially stand on end, which may impede its progress. It is something that never happens.

Next, a feed roller that is driven in the same direction as the rotation direction of the brush roller is disposed between the guide table and the frontmost brush roller, which eliminates the need for manual feeding operation and allows the workpiece to be processed. This enables smooth automatic feeding of the material.

In addition, in this invention, the height of the front part of the press plate can be changed at any time using a lever-operated adjustment mechanism to suit the type and size of the object to be processed. This allows for a dramatic improvement in performance.

(Example) Hereinafter, an example of the device of the present invention will be described in detail based on the drawings.

Figure 1 is an overall perspective view of the device of the present invention, Figure 2 is a perspective view showing the front area of the pressing plate, Figure 3 is a side view of the pressing plate and its support device, and Figure 4 is the area around the lever adjustment mechanism. FIG.

In the figure, reference numeral 1 denotes a water tank provided at a relatively lower part of the main body of the apparatus, and between its side walls 2, there are a plurality of brush rollers 3 extending from the front part F, which is the supply side of the processed material, to the rear part A, which is the outlet thereof. are arranged in parallel so that they can be freely rotated. Each brush roller 3 is made up of a cylindrical body 5 that rotates around a central axis 4, and brush bristles 6 made of horse hair or the like are planted on the circumferential surface of the cylinder 5.

Reference numeral 7 denotes a plurality of pressing plates arranged to cover the upper surface of the brush roller 3. The pressing plate 7 of this example includes a horizontal plate 7a whose main function is to press the object to be processed, and an inclined plate 7b whose main function is to guide the object to be processed supplied from the front part of the apparatus. Both boards 7
a, 7b are connected and fixed by an elongated plate 7c so that the overall shape is inverted, and both plates 7a, 7
The brush bristles 7d are arranged in a slanted manner on the lower surface of b, following the direction of transfer of the object to be treated. That is, as shown in FIG. 2, on the side of the horizontal plate 7a, the brush bristles 7d form an angle θ1 with respect to the perpendicular line 8 of the plate surface.
The angle θ2 of the plate surface with respect to the perpendicular 9 is set to be 10 to 40 degrees, and on the side of the inclined plate 7b, the angle θ2 of the plate surface to the perpendicular line 9 is set to be inclined toward the backward side at approximately 30 degrees. The reason why the lower limit of θ1 is set to approximately 10 degrees is because of the transfer of the processed material.
This is to prevent the bristles 7d of the horizontal plate 7a, which is lifted up by the object to be processed, from acting in an upright state that would impede the progress of the object to be processed, and the reason why the upper limit was set at 40 degrees is that the brush bristles 7d of the horizontal plate 7a, which is lifted by the object to be processed, are not allowed to stand on end. This is because the brush bristles 7d of the horizontal plate 7a come into contact with the circumferential surface of the workpiece in a state approximately perpendicular to the workpiece, thereby effectively pressing the workpiece. It will be slightly different depending on the situation. Further, it is the same as above that θ2 is set to approximately 30 degrees, but in this case, it changes depending on the inclination angle of the guide table 34 in addition to the shape of the object to be processed.

Therefore, the support of the pressing plate 7 is carried out by the hanging support device 1.
Specifically, the L-shaped cross-section plate 11 is supported by a support roller of a lever adjustment mechanism, which will be described later, and the rear horizontal frame H1 of the device body is hooked and supported. Support beams 13 in the front-rear direction are erected and fixed between the L-shaped cross-sectional plates 12 and at positions directly above each pressing plate 7,
As shown in FIG. 3, each support beam 13 and the approximate center of the elongated slope 7c are connected and fixed by a spring plate 15 via an appropriate fastening fitting 14, and the front and rear sides of the elongated plate 7c are Protrusions 16, 16 are fixed at the locations, and the lower ends of guide rods 17, 17 are pivotally connected to these, and the upper parts of the guide rods 17, 17 are attached to the support beam 1.
3 and the guide tube 1 fixed to the support beam 13.
Springs 18, 18 are inserted into the holes 3a, 13a and urge the guide rods 17, 17 downward to a certain position, and L-shaped metal fittings are provided at both ends of the L-shaped plate 11. 19, 19 (see Fig. 4) with bolts and the L-shaped fitting 1.

0 and 20 so as to be slidably displaceable. As a result, the press plate 7 is restricted to a fixed position in a movable state, and when a force pushing up the plate 7 from below acts, the spring 1
8 and 18 are compressed and raised, or the entire suspension support device 10 is suspended from the front and rear horizontal frames H1 and H2.
will surface and rise.

Reference numeral 21 denotes a lever adjustment mechanism for adjusting the height of the front portion of the pressing plate 7, and in this example, it is constructed as follows. That is, as shown in FIG.
Attach them horizontally at appropriate intervals. A rotation center shaft 24 is inserted through one of the cylindrical bodies 22, and an operating lever 25 is pivotally attached to the outer end of the shaft.
An arm 26 is fixed to the inner end, and the arm 2
A support roller 27 is pivotally attached to the tip of the cylindrical body 6, and a rotational center shaft 28 is also inserted through the other cylindrical body 23 so that it can only rotate freely, and an arm 29 is fixed to the inner end of the cylindrical body 23. At the same time, the arm 2
A support roller 30 is pivotally attached to the tip of the lever 9, and both arms 26 and 29 are connected by a connecting rod 31. In addition, a fourth arm is provided for locking the operating lever 25 at an arbitrary predetermined rotational position. A locking plate 32 (see FIG. 1), which is not shown in the drawing, is fixed to the front horizontal frame H2 of the main body of the apparatus. Here, the swinging operation of the operating lever 25 causes a swinging displacement of the arm 26, and also causes a symmetrical swinging displacement of the other arm 29 via the connecting rod 31, thereby moving the two support rollers 27, 30. The L-shaped body 11 in cross section is supported by these rollers 27 and 30 and acts to be vertically displaced in a certain relationship.
is vertically displaced within a certain height range, and at the same time a similar displacement is produced in the front part of the pressing body 7.

Reference numeral 33 denotes a feed roller disposed in parallel near the front of the frontmost brush roller 3, and is configured to be driven in conjunction with the brush roller 3, for example. The surface of the roller 33 is preferably made of a rubber material or the like to increase friction with the object to be processed that comes into contact with it.

Reference numeral 34 is a guide stand for supplying the material to be processed, and 35 is a cover which also plays the role of slidingly guiding the leaves of the material to be processed, such as radish.

When using the device of the present invention having the above configuration, after starting the drive device (not shown) and rotating the brush rollers 3 and the feed roller 33, the object to be processed, such as radish or burdock, is placed on the guide table 34 by the brush rollers. Make sure to supply it in the same direction as in step 3. The objects to be processed thus supplied are forced to be sequentially fed to the brush roller 3 side by the feeding roller 33, and there is no need to push them manually as in the conventional case. At this time, depending on the type and size of the workpiece, the press plate 7
There may be cases where the mutual gap between the front part of the press plate 7 and the brush roller 3 is not appropriate. So do it.

When the workpiece is sent onto the brush roller 3, the pressure plate 7 swings back and forth and tilts above it, causing the brush bristles 7d to face the workpiece. However, in this device, the bristles are planted so that they retreat at a constant angle toward the direction of travel, so that there is no risk of some of the bristles 7d standing upright in relation to the workpiece and obstructing its progress, as in the conventional brushes.

In the present invention, as a result of various experiments using radish as the object to be treated, it has been found that good results can be obtained by setting the above-mentioned inclination angle θ1 in the range of about 10 degrees to 40 degrees. That is, in this angle range, not only will none of the brush bristles stand up during the swinging motion of the press plate 7 and obstruct the progress of the object to be treated, but the tips of all the brush bristles will be close to the circumferential surface of the object to be treated. The most effective contact state is in the tangential direction, and if θ1 is greater than 45 degrees, there will be no hindrance to the progress, but the effective sliding action as described above will not be obtained.

(Effects of the invention) As described above, the present invention not only makes it possible to efficiently wash the object to be treated, but also prevents the brush bristles on the press plate from standing up partially, which means that the bristles are not rough or damaged. This will prevent this and improve durability.

Further, by providing a feed roller between the brush roller and the guide table on the entrance side, the feed force based on the drive acts on the object to be processed, so there is no need to manually push the object.

The adjustment mechanism using a lever allows the distance between the front part of the press plate and the frontmost brush roller to be adjusted appropriately to the size of the workpiece, so that it can be adjusted immediately when the type or size of the workpiece changes. This will result in a dramatic improvement in work efficiency.
