Japanese Patent Laid-Open No. 10-14552

  However, the conveyor 81 of the follicle removal device often has a paddle with soil attached to the surface, and the soil falls and adheres to the tooth bottom 91 (see FIG. 6) of the sprocket 90 and accumulates. , Causing the roller chain 88 to fly over. Thus, when one roller chain 88 causes a mountain jump, the left and right roller chains 88 connected via the wire 83 are out of phase with each other, the conveyor 81 is locked, and conveyance stops. is there. As a means for preventing the mountain jump, a means for forcibly removing the soil by crushing the soil with a pin of the roller chain 88 fitted into the tooth bottom 91 by tensioning the roller chain 88 is generally used. In this means, the roller chain 88 is forced and the chain stretches quickly, and the tension or replacement of the roller chain 88 is often forced. Since the roller chain 88 is a special part having a structure in which a pair of chains are connected by a large number of wires 83, the roller chain 88 is expensive, and because of its special structure, it takes a lot of time to replace it. Yes.

In order to solve the above-described problem, the root vegetable transporting apparatus of the first invention is
An annular chain that circulates between the upper part and the lower part of the frame, a large number of placement members attached to the annular chain, and a sprocket around which the annular chain is wound, is placed on the placement member. A root vegetable transporting device for transporting root vegetables,
The sprocket is formed such that the thickness of the edge at the root of the tooth is relatively thinner than the thickest part among the other parts of the tooth.

  According to this structure, since the thickness of the edge part in the said tooth bottom is formed relatively thin, adhesion and accumulation | storage of the soil to a tooth bottom can be prevented. Also, if attached, the edge thickness at the root of the tooth is relatively thin, so that even if the annular chain is not stretched as strongly as before, the pressure is concentrated on the soil attached to the narrow tooth bottom efficiently. Can be eliminated. And since the thickness of the whole tooth | gear is not made thin, the rattling of the said annular chain hardly arises. Therefore, according to the present invention, the mountain chain can be prevented from jumping and the root vegetables can be stably conveyed.

As a root vegetable conveying device of the second invention, in the first invention,
The sprocket exemplifies a mode in which the thickness of the edge portion at the bottom of the tooth is formed in a tapered shape that becomes thinner as it approaches the edge side.

  According to this configuration, the strength of the bottom of the tooth is prevented from decreasing by forming the edge thicker toward the side farther from the edge side, and the soil adheres to the tooth bottom by forming the edge thinner toward the side closer to the edge side. And accumulation can be further prevented.

The root vegetable processing machine for root vegetables of the third invention is
A root vegetable transport device according to the first or second aspect of the invention, and a root hair removing means for removing root hairs of the root vegetables placed on the placement material described above of the transport device.

  According to this structure, in the root hair processing machine of root vegetables, the effect similar to the root vegetable conveying apparatus of 1st or 2nd invention can be acquired.

  According to the root vegetable conveying device and the root hair processing machine according to the present invention, it is possible to prevent the skip of the annular chain that is a component thereof and to stably transport the root vegetables.

  1 to 4 show an embodiment embodying the present invention. The root vegetable processing machine 1 for root vegetables M according to the present invention is a root hair removal means for removing the root hair Ma of the root vegetables M placed on the transport device 2 of the root vegetables M and the placing material 3 of the transport device 2. A burner 4, a watering nozzle 5 as a cooling means for cooling the mounting material 3 heated by the burner 4, and a watering receiver 6 that collects and discharges water discharged from the watering nozzle 5. ing.

  The transport device 2 is supported by the upper ends of the pillars 11a erected at the four corners, and circulates between the machine frame 11 including the frame 11b formed in a rectangular frame shape in plan view, and the upper and lower parts of the frame 11b. A pair of annular chains 12, a large number of mounting members 3 attached to both the annular chains 12, sprockets 16, 18, and 19 around which the annular chains 12 are wound, and an upper portion of the frame 11b. And a guide plate 14 for feeding out the root vegetables M that have been placed and transported on the placing material 3.

  A pair of rotary shafts 15 extending in the frame width direction are rotatably supported on both ends of the frame 11b in the front-rear direction of the machine frame 11, and sprockets are provided on both ends of the rotary shaft 15 on the rear side of the machine body. 16 are attached, and sprockets 18 are attached to both ends of the rotary shaft 15 on the front side of the machine body. In addition, a pair of left and right rotating shafts 17 extending in the frame width direction are rotatably supported on the machine frame 11 below the center portion in the front-rear direction of the frame 11b, and a sprocket 19 is provided on each rotating shaft. It is attached. On the other hand (in this example, the rear side of the machine body) the rotary shaft 15 is driven by a drive motor 21 via a chain transmission mechanism 20, and an annular chain is connected via a sprocket 16 attached to the rotary shaft 15. 12 is driven. The rotary shaft 17 is supported by the tip of an arm 23 that rotates about a shaft 22 so that the rotary shaft 17 can move up and down, and the tension spring means 24 that urges the arm 23 to rotate downward. Is applied downward to apply tension to the annular chain 12.

  The pair of annular chains 12 are positioned on both sides in the frame width direction by being wound around three sprockets 16, 18, and 19, respectively. Each annular chain 12 is formed by connecting a large number of frames 12a, and a projecting portion 25 having a hole 25a for mounting the mounting material 3 is provided inside the frame 12a in the frame width direction. (See FIG. 3).

  A large number of mounting members 3 are attached at a constant pitch so as to connect the projecting portions 25 at opposite positions of the annular chains 12 on both sides. In this example, female screw portions 3a are provided at both ends of each mounting material 3, and each female screw portion 3a inserted through the hole 25a of the protruding portion 25 is detachably attached by a nut 26 (FIG. 3). Each mounting material 3 is formed by bending a wire-like wire having the required rigidity, and is provided with a recess 27 for positioning the root vegetables M, and is formed substantially in an M shape. This configuration is an example, and the present invention is not limited to this, and two or more recesses 27 can be provided. The placing material 3 that moves in the upper part of the frame 11 b forms a conveyance path 30, and a receiving plate 31 is arranged below the placing material 3 in the most upstream area 30 a of the conveyance path 30. It is installed. The receiving plate 31 is formed in a substantially V-shaped cross section so that the upper surface of the receiving plate 31 is spaced apart from the placing material 3, and the root vegetables M (particularly the small root vegetables M) are placed between the placing materials 3. The tip is prevented from being fitted. If the root vegetables M are sent while the tip of the root vegetables M is sandwiched between the placement materials 3, the root vegetables M are sandwiched between the placement materials 3 and the guide plate 14 in the most downstream portion 30 b of the conveyance path. However, it is difficult to prevent the annular chain 12 from being caused by the receiving plate 31.

  As shown in FIG. 4, the sprocket 16 has a portion where the thickness of the edge 34 a at the root 34 of the tooth 33 is the thickest among the other portions of the tooth 33 (in this example, the tooth In the taper shape, the thickness of the edge portion 34a of the tooth base 34 of the tooth 33 becomes thinner as it approaches the edge side. Is formed. In this example, this configuration is implemented by forming an annular groove 36 having a substantially V-shaped groove cross section provided on both sides of the sprocket 16 so as to pass through the edges of all the tooth bottoms. . The teeth of the sprockets 18 and 19 are configured in the same manner as the teeth 33 of the sprocket 16. Note that the driven sprockets 18 and 19 that do not drive the annular chain 12 do not need to be provided with the teeth 33, and therefore can be replaced with a disk-like member formed so that the annular chain 12 can be wound around. According to such a disk-shaped member, since the teeth 33 are not provided, there is no problem that soil adheres to the tooth bottom 34 as a matter of course.

  According to the conveying device 2 of the root vegetable M of the present example configured as described above, the sprocket 16 has a thickness of the edge portion 34a at the root 34 of the tooth 33 in the other parts of the tooth 33. Therefore, it is possible to prevent the soil from adhering to and accumulating on the tooth bottom 34 because it is formed relatively thinner than the thickest portion (the central portion 35 in the tooth length direction). In addition, when attached, the edge 34a of the tooth bottom 34 is relatively thin, so that the pressure is concentrated on the soil attached to the narrow tooth bottom 34 even if the annular chain 12 is not stretched as strongly as before. The soil can be efficiently removed. And since the thickness of the whole tooth | gear 33 is not made thin, the rattling of the engagement with the annular chain 12 hardly arises. Therefore, according to the present invention, the mountain chain 12 can be prevented from jumping and the root vegetables M can be stably conveyed.

  Further, the sprocket 16 is formed in a taper shape in which the thickness of the edge portion 34a of the tooth bottom 34 of the tooth 33 becomes thinner as it approaches the edge side. In addition to preventing a decrease in the strength of 34, the thinner the side closer to the edge side, the more the adhesion and accumulation of soil to the tooth bottom 34 can be further prevented.

  Moreover, according to the root hair processing machine 1 of the root vegetables M of this example, since the transport device 2 for the root vegetables M is provided, the same effects as the transport device 2 can be obtained.

In addition, this invention is not limited to the said embodiment, For example, it can also be suitably changed and embodied as follows, for example in the range which does not deviate from the meaning of invention.
(1) Change the cross-sectional shape of the tooth bottom 34 of the tooth 33 as appropriate.
(2) A rooting hair removal means, a cooling means, etc. are omitted, and it is configured as a transport device that simply transports the root vegetables M.
