Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a stem pulling machine that pulls out the stems and leaves of root vegetables such as potatoes, ginger, and bulbs that are exposed above the ground, and leaves the roots in the soil.

(Conventional technology) Root vegetables such as potatoes have roots in the soil.
Stems grow above the ground.

Conventionally, when harvesting root vegetables in such soil,
A digging machine is used to dig up the soil and harvest root vegetables. In order to harvest with a digging machine, the stems of root vegetables are often pulled out by hand beforehand, as they interfere with the work of the digging machine. In addition, a device for pulling out the stems and leaves of underground crops using an endless belt was published in 1983.
It is known from Publication No. 39084.

(Problem that the invention aims to solve) However, pulling out the stems by hand from the ridges is a labor-intensive and time-consuming task, and moreover, it is hard work to do it manually on vast farmland. Furthermore, the method of removing leaves using an endless belt as disclosed in Japanese Patent Publication No. 59-39084 had the problem that separate conveyor belts were required to send the removed leaves to the right and left of the ridge, making the device complicated and expensive. Further, there was a problem in that the transfer of the leaves from the endless pulling belt to the conveyor belt was not successful and the picked leaves were scattered.

(Means for Solving the Problems) The object of the present invention is to solve such problems and to provide an inexpensive stem removal machine and removal machine that can continuously and smoothly perform everything from pulling out stems and leaves to feeding them to the left and right of the ridge using a simple mechanism. Another object of the present invention is to provide a more reliable stem removal machine.

The gist of the present invention is as follows: 1. A pair of endless belts are provided on the machine body with adjacent belt surfaces in contact with each other, and
A pair of endless belts are driven so that the front side of the traveling side is low and the rear side is high, and the belt surfaces in contact are sent from the front to the rear. The belt is characterized by a structure in which an interlocking part is formed to strongly grip the stems of root vegetables, and the upper half of the endless belt is swingable so that the separation point of the contacting belt surface can swing widely from side to side. An endless chain is provided inside the lower half of each endless belt, and a number of belt pressing pieces attached to the outside of the endless chain forcefully bend the endless belts so that they mesh in a serpentine shape. The root vegetable stem remover 3 according to claim 1, wherein the belt pressing piece and the endless belt are provided with an engaging portion to prevent the endless belt from falling downward. It's on the stem remover.

(Function) In the present invention, when the stem removal machine moves along the ridge by being self-propelled or being towed by a management machine, the stems and leaves on the ground surface of the ridge are introduced into the front contact part of the pair of endless belts, and the stem removal machine moves along the ridge. It is sandwiched between the belts and strongly gripped by the interlocking part, and as it is sent backwards, the endless belt is tilted and the gripping point moves upward, increasing the tensile force against the stems and leaves, leaving the roots underground. It is cut in the middle and the stems and leaves are pulled out. The extracted stems and leaves are lifted directly above the endless belt, released from the separation point, and fall. The separation point is such that the upper half of the endless belt is swung to either the left or right, so that the extracted stems and leaves can be continuously sent as they are and fall smoothly to either the left or right of the ridge.

In particular, if an endless chain is provided inside the lower half of the endless belt, and the endless belt is forcibly meandered by a large number of belt pressing pieces attached to the outside of the endless chain, a strong gripping force for the foliage can be obtained. Furthermore, if an engaging portion is provided between the belt pressing piece and the endless belt to prevent the endless belt from falling downward, the endless belt will not be pulled by the leaves and will not slip downward.

(Example) Examples will be described below based on the drawings.

Fig. 1 is a plan view showing the main mechanism of this embodiment, Fig. 2 is a side view of the same, Fig. 3 is a plan view showing a belt pressing piece attached to an endless belt, Fig. 4 is a side view of the same,
FIG. 5 is a cross-sectional view showing the cross-sectional shape of the endless belt.

In the figure, 1 and 2 are endless belts, 3 is a meshing part, 4 is a separation point, 5 is a machine body, 6 and 7 are endless chains, 8 is a belt pressing piece, 9 is an engagement part, 10 is an endless belt 1,
2, an engagement protrusion 2, 11 a fitting space between the upper and lower belt pressing pieces into which the engagement protrusion fits, 12 a foliage scraping impeller, 13 and 14 an endless belt driven wheel, 1
5 and 16 are extendable arms that hold and swing the driven vehicle; 17 is a spring that biases the arm in the direction of extension; 18 is a spring that connects the arms 15 and 16; 19 and 20 are endless chains; 2
1 is a belt pressing piece mounting bracket, 22 is an engine, 2
3 is a management machine, 24 is a cover, and 25 and 26 are centers of rotation of the arms 15 and 16.

In this embodiment, the upper halves of the endless belts 1, 2 are stretched under tension by driven wheels 13, 14 attached to the ends of extendable arms 15, 16.
Moreover, it can swing greatly around its rotation centers 25 and 26, and its endless separation point 4 can be swung left and right, so that the leaves and leaves held between the endless belts 1 and 2 can be sent to the desired direction on either the left or right side. The separation point 4 is opened and the object can be dropped.

Further, the adjacent endless belts 1, 2 are bent in a meandering manner by the belt pressing pieces 8 attached to the left and right endless chains 19, 20, so that the endless belts 1, 2 can be driven and the leaves can be strongly clamped.

Furthermore, since the engaging protrusions 10 of the endless belts 1 and 2 fit into the fitting spaces 11 between the upper and lower belt pressing pieces 8, there is no vertical movement of the endless belts 1 and 2, and even if the belts are pulled downward by stems and leaves, the belts will not move. can be reliably fed without falling downward.

Further, the feeding of the foliage to the endless belts 1 and 2 is performed by a foliage scraping impeller 12.

(Effects of the invention) As described above, according to the invention, it is possible to reliably pull out the leaves and leaves at the meshing portion of the pair of endless belts, and the continuously pulled out leaves and leaves can be conveyed smoothly to either the left or right side. It became. In addition, the falling point of the pulled out leaves can be easily switched to either the left or right by swinging the upper half of the endless belt to make an appropriate angle, and the falling direction can be easily changed by reciprocating the ridges. can.

Moreover, since there is no need for a separate horizontal conveyor for horizontal movement, the structure is simple and can be manufactured at low cost.
