Description

  The present invention relates to a root hair processing machine for root vegetables such as moss, and more specifically, in a root hair processing machine that incinerates root hair with a burner while processing the root vegetables on a chain conveyor, and the soil adhering to the root vegetables is It prevents falling to the chain side, increasing the durability of the chain and preventing the chain from coming off the sprocket.

Root vegetables such as moss have root hairs extending from the surface in the harvested state, and therefore, root hair removal treatment is performed to improve the appearance and increase the commercial value. For example, Japanese Patent Application Laid-Open No. 10-14552 A root hair removing device 1 is provided in the publication (Patent Document 1).
In Patent Document 1, as shown in FIG. 6, the root hair removal device 1 is provided with a conveyor 2 on which a large number of wire rods 3 are mounted on a roller chain 6, and a burner 4 that radiates a flame toward the conveyed cage. And a fixed capacity cooling water container 5 filled with cooling water is disposed below the conveyor 2.

  The root hair removal operation of the cocoon by the root hair removing device 1 is carried out by placing the cocoon with the extended root hair on the wire 3 located at the upper end 2a of the conveyor 2, and the flame by the conveyor 2 is radiated. The root hair is incinerated and removed by passing through the front of the burner 4, and the processed soot is conveyed to the other end 2b. Further, the wire 3 is also heated by the flame radiation of the burner 4, but when the wire 3 is circulated downward, it is cooled by passing through the cooling water container 5, returning to the upper side, and placing the rod again. In order to avoid adverse effects of high heat on the cocoons.

However, since the roller chain 6 of the conveyor 2 is bare in the root hair removing device 1 of the above publication, sand or the like attached to the ridges placed on the wire 3 falls and adheres to the chain 6. The sand adhering to the chain 6 may also cause the sand itself to get caught between the sprocket and the chain when the chain 6 comes into contact with the sprocket, greatly reducing the durability of the chain 6 and causing troublesome chain replacement work. It becomes easy to do. Furthermore, the adhered sand accumulates on the chain 6 and the sprocket, and the chain and sprocket may not be properly fitted, and the chain may come off from the sprocket.
Moreover, since the water-cooling type is adopted for preventing the wire rod 3 from being heated, the chain 6 is splashed with water and cannot be lubricated.
Japanese Patent Laid-Open No. 10-14552

  This invention is made | formed in view of the said problem, and makes it the subject to improve the durability of the chain of a root hair processing machine, and to prevent that a chain remove | deviates from a sprocket.

In order to solve the above-described problems, the present invention is configured such that a large number of mounting materials are attached with a space between a pair of left and right annular chains, and the annular chain is wound around a sprocket to thereby form an upper part and a lower part of a frame. In the root hair processing machine provided with a conveyor for root vegetable transport that circulates and drives, and provided with a burner that incinerates and removes root hair of root vegetables at the upper circulation position of the conveyor,
The above-mentioned mounting material is a chain that keeps a distance between the central root vegetable mounting part and the annular chain mounting parts at both ends and shields the annular chains on both sides from the central root vegetable mounting part at this continuous position. A protective cover is provided, and the chain protective cover provides a root vegetable processing device for root vegetables arranged vertically from the upper drive position to the lower drive position of the annular chain.

The mounting material described above is formed by bending a metal wire, oriented at a constant pitch, and both sides thereof are connected to an annular chain. The mounting material is not limited to a metal wire, and may be a band material, a net material, or a punching material having a required width. In the present invention, the distance between the central root vegetable mounting portion and the annular chain attaching portions at both ends is increased, and the chain protective cover can be installed therebetween.
In this way, since the chain protection cover is interposed between the central root vegetable mounting part of the mounting material and the annular chains at both ends, sand from the root vegetable placed on the central root vegetable mounting part is chained. It is shielded by the protective cover and can be prevented from hanging on the annular chain. Therefore, durability of the annular chain is improved, troublesome chain replacement work is reduced, and it is possible to prevent the chain from being detached from the sprocket.

  Each of the pair of left and right annular chains is formed into an annular chain by connecting a number of pieces at both ends of the linear shape with a detachable joint material from a linear state in which a number of pieces are sequentially connected to be freely rotatable. In the connection part by a simple joint material, both ends of the above-mentioned mounting material are screwed and fixed to the joint material, while in other parts, both ends of the above-mentioned mounting material are fixed to the annular chains on both sides by rivets. It is preferable.

As a method for fixing both ends of the mounting material to the left and right annular chains, there are screw fastening and rivet caulking. Since screw fastening requires a screw fastening operation, the productivity is poor, and there is a disadvantage that the mounting material tends to be inclined in the screw fastening direction, but there are advantages that it can be removed freely. The rivet caulking has a drawback that it is difficult to remove the rivet caulking while it has a good productivity because it can be attached with one touch.
Therefore, with the above-described configuration, when the annular chain is replaced, the mounting material is easily removed by removing the screw from the portion from which the joint material has been removed, which facilitates the work of separating the chain and improves the workability. In addition, since the placing material and the chain are fixed by rivet caulking at locations other than the place where the joint material is disposed, the assembly work of the chain and the placing material is facilitated, and the productivity is improved. That is, it is possible to achieve both the productivity and the maintainability of a conveyor in which a large number of placement materials are fixed to an annular chain.

  The burner is attached to a support column fixed to the frame and disposed above the mounting material, and the burner with respect to the support column can be mounted by changing the position of the support column in the front-rear direction with respect to the frame. It is preferable that the direction of is variable.

  With this configuration, since the mounting position in the front-rear direction of the support pillar for the burner can be changed, it is possible to adjust the position so that the worker does not interfere with the work when placing the root vegetables on the placement material. . Moreover, since the direction of the burner with respect to the support column is variable, a flame adapted to the root of the root vegetable can be obtained.

  It is preferable that a sprinkling nozzle for cooling the placing material is attached to the frame at a central position where the chain protective cover is interposed with respect to the annular chain.

  If it is set as the said structure, since the mounting material is stably cooled with the cooling water discharged from a watering nozzle, the cooling efficiency of a mounting material improves. In addition, since the chain protective cover is interposed between the annular chain and the watering nozzle, it is possible to prevent water from being applied to the annular chain and to lubricate the chain.

A water tank with an upper surface opening is provided below the watering nozzle, and the water tank protrudes a flange on the side surface and the bottom surface is uneven.
An L-shaped piece that supports the flange of the water tank is suspended from the frame, and a lower receiving material having a convex portion that can be fitted into a concave portion on the bottom surface of the water tank is provided in the width direction. preferable.

  If it is set as the above-mentioned composition, it can be positioned in a suitable position when inserting and installing a water tank from back by receiving a collar part from the front by L character piece. And final positioning is carried out back and forth and right and left by mounting the bottom of a water tub on a lower receiving material, and fitting the crevice of the bottom of a water tub with the convex part of a lower receiving material. Therefore, the operation of taking in and out the water tank at the time of maintenance for removing sand and the like accumulated in the water tank is facilitated.

  As is clear from the above description, according to the present invention, the distance between the root vegetable mounting portion of the placing material and the annular chains on both sides is increased, and the chain protective cover is interposed therebetween, It is possible to prevent sand or the like from the root vegetables placed on the resting material from being blocked by the chain protection cover and hanging on the annular chain. Therefore, the durability of the annular chain is improved, and the need for troublesome chain replacement can be reduced.
