JPS59130175A - Apparatus for removing soil from bulb or tuber - Google Patents

Abstract

PURPOSE:To scrape off the soil attached to the surface of a bulb or tuber, completely, by extending a cylindrical mesh composed of flexible strings laterally in a rotary frame, putting the bulb with soil in the cylindrical mesh, and rotating the mesh to cause the rotation of the bulb. CONSTITUTION:A cylindrical mesh 5 composed of flexible strings is extended laterally in a rotary frame 4. A bulb or tuber such as potato attached with soil is thrown into the cylindrical mesh 5, and the mesh 5 is rotated to scrape off the attached soil completely from the bulb while rotating the bulb. The cleaning efficiency of the apparatus is remarkably high compared with the case comprising the cleaning by hand using a brush, and furthermore, a cleanly finished bulb free from damage and having high quality can be obtained.

Description

[Detailed Description of the Invention] Traditionally, potatoes harvested in clay areas are delicious and their cultivation has become popular, but when harvesting, the mud that sticks to the surface cannot be easily removed, and the potatoes are cut into pieces with bundles etc. It took a lot of manual labor to scrub each drum.

This invention provides a bulb scraper that can easily scrape off soil stuck to potato handles harvested especially in clay areas. Four strings are hung horizontally inside the rotating frame, and the above-mentioned bulbs are thrown into the cylindrical mesh, and as the cylindrical mesh rotates, the bulbs are rotated and the soil firmly attached to the surface is removed. It is characterized by evenly scraping.

One embodiment of the present invention will be explained with reference to the drawings. Reference numeral 1 denotes a machine frame of an earth-dropping machine, and this includes opposing left and right wheels 2.
' A rotating frame 4 in which IM and i are integrally connected by a plurality of connecting rods 3, 3 is mounted so as to be rotatable in the direction of lateral force. 5 is a flexible warp, weft, and weft line 5σ made of a synthetic resin material such as nylon.

It is a cylindrical mesh body composed of 5σ', with both left and right ends open, occupying the inner space of the rotating frame 4, and connecting rods 3, 3.
It is suspended in the horizontal direction in a tensioned state and rotates integrally with the rotating frame 4. 6 is the supply gutter, 7 is the discharge 4i
i, facing openings at both left and right ends of the cylindrical mesh body 5, respectively.

Note that the rotating frame 4 is disposed at a somewhat lower position on the side of the supply gutter 6 and on the side of the outlet gutter 7. 8 is a shutter 2 that can be opened and closed to close one part between the nets of the discharge gutter 7; 9 is a motor installed on the machine frame 1; the motor pulley of the motor 9 and the wheel of the oral transmission frame 4; A belt is appropriately suspended between the two, and the rotating frame 4 is rotated by the rotation of the motor.

10 is a bulb.

Since the present invention is configured as described above, when the motor 9 is driven to rotate, the rotating frame 4 rotates together with the cylindrical mesh body 5. Now, if bulbs such as soil-grown potatoes are supplied onto the supply gutter 6 and thrown into the cylindrical net 5, the bulbs 10 will rotate upward to a certain degree as the cylindrical net 5 rotates upward in the direction of the arrow. ,
While it rolls down on the net body without being able to resist the weight, the weft line 5σ' digs into the soil that has adhered to the surface due to the sliding friction with the flexible yarn lines 5a and 5σ of the net body 5 rotating on the top surface. stripped down.

In this way, while rolling up and down on the inner peripheral surface of the net 5 and rotating, the soil adhering to the bulb surface is evenly scraped off. At this time, since the net body 5 is composed of flexible warp spun wires 5σ and 5a' made of synthetic resin material such as nylon, the mesh body 5 is made of flexible warp spun wires 5σ and 5a′, so that the mesh body 5
As shown in Figure 3, the thread line, which has 4 properties and strength, is wrapped along the surface of the bulb, and the soil on the surface is scraped off by rubbing on two sides of the weft line 5σ', leaving a clean surface without damage. The bulbs are obtained.

The scraped soil passes through the mesh and is discharged outside the machine.

In this way, the present invention suspends a cylindrical net made of flexible threads in the horizontal direction within a rotating frame, and inserts earth bulbs into the cylindrical net. Since this is a bulb dirt removal machine that is configured to remove hard soil from the bulbs by rotation of the bulb, the soil attached to the surface of the bulbs is thoroughly scraped off evenly, and its efficiency is higher than that of conventional bundling etc. This is significantly more expensive than when wiping it off manually, and it also has the effect of providing a clean finish with no damage and of good quality.

[Brief explanation of the drawing]

The drawings show an embodiment of the bulb-dropping machine of the present invention, in which Fig. 1 is a perspective view seen from the discharge side, and Fig. 2 shows a state in which a cylindrical mesh body is suspended within the rotating frame. The front view shown in FIG. 3 is an explanatory view of the function.

Claims (1)

[Claims] A cylindrical net made of flexible light beams is suspended in the direction of lateral force inside a rotating frame, and bulbs with tops are introduced into the cylindrical net, and the rotation of the cylindrical net causes the bulbs to harden onto the soil.
