Description

  TECHNICAL FIELD The present invention relates to a foreign matter removing machine for farms that removes foreign matter such as volcanic ash and pests adhering to tea plantations by vibration.

  In farms, for example, tea gardens, chemical spraying is usually performed to control pests adhering to buds, leaves and branches of tea plants. However, the spraying of the chemical solution is more difficult to spread on the back of the leaf than the leaf surface, and thus there is a problem that the amount of sprayed chemical solution must be increased to sufficiently control the pests.

  In recent years, especially in the South Kyushu region, the impact of the ash fall of the volcanic ash on the plantation has been considerable. For example, in tea gardens, if volcanic ash adheres to shoots or tea leaves at the time of shoots or growth, it causes poor growth of shoots or tea leaves. It had to be removed, and this was a factor causing an increase in production cost and a decrease in quality.

  The present applicant has previously proposed an unusable waste collection apparatus for farms that vibrates trees by rotating a rotating brush and collects unneeded materials separated from the branches and leaves by the suction duct using a suction duct (see Patent Document 1). In addition, a vibration conveyor is installed in a part of the tea production line to accommodate the harvested tea leaves, and the vibrations for tea leaves are used to screen out foreign matters such as cut leaves, twigs, pebbles or garbage mixed in the tea leaves. A conveyor has also been proposed (see Patent Document 2).

JP 2010-104274 A JP 2009-159867 A

  However, the apparatus of Patent Document 1 is a system in which the tea leaves are simply swung back and forth with a rotating brush, and there are cases where foreign matter remains due to, for example, overlapping portions of tea leaves caused by the brush that rotates and advances. In addition, when the volcanic ash that fell on the previous day and adhered to the tea leaves flowed with morning dew or light rain on the harvest day and stuck to the branch or its branch part, the sticking part could not be completely removed. The conveyor of Patent Document 2 has a problem that the tea making process is increased because a vibrating conveyor for removing foreign substances is arranged in a part of the tea making process, and that the removed foreign substances are collected and discarded from the tea making process (usually performed indoors). There are challenges.

  The present invention has been made in view of the above problems, and is a plantation that can effectively remove foreign matter such as volcanic ash adhering to the branches and leaves by densely imparting vertical and horizontal vibrations to the branches and leaves of tea trees and the like planted in the plantation.

The following is described with reference to FIG.

  First, in the tea garden, the work machine 100 is positioned with respect to the tea tree T planted in the tea plantation, and the upper and lower booms 134 and 138 are lowered from the raised position by the operation of the lifting cylinder 133, so that the vibration applying member unit U is set as a vibration applying position for the tea tree T (for example, the distance L from the surface of the tea tree T to the lower end position of each vibration applying member 131 is set from 50 cm to 150 cm). In addition, the height position of the cutting blade portion 140 with respect to the tea tree T is set.

  Next, as shown in FIG. 5, while the work machine 100 is advanced at a low speed so as to straddle the tea tree T, the operator operates the operation panel 114 to remove the volcanic ash adhering to the branches and leaves of the tea tree T; Continue to harvest tea tree T.

  As shown in FIG. 6, the driving motor 135 is driven by the driving force from the prime mover 115, and the vertical cam and the left and right (width direction) vibrations cause the lower boom 138 through the driven arm 137 by the rotation of the eccentric cam 136. Via the vibration applying member 131 of the vibration applying member unit U. Each vibration imparting member 131 imparts vertical and horizontal vibrations to the branches and leaves of the tea tree T, and volcanic ash attached to the branches and leaves of the tea tree T is peeled off by the vibrations. That is, the lump of volcanic ash stuck to the branches and leaves peels off due to its weight and falls to the ground as shown by the arrow A1 in FIG. 5, and the granular volcanic ash attached to the branches and leaves peels off due to its lightness and floats. It falls to the ground as time passes. In addition, when a pathogen is attached to a branch and leaf, the pathogen is dropped from the branch and leaf by vibration.

  The vibration imparting member unit U is arranged in a staggered arrangement in which the vibration imparting members 131 are arranged along the lower boom 138 in two rows in the front and rear with a close interval (for example, 30 cm to 50 cm) and are shifted by a half pitch between the front row and the back row. Therefore, even if there is a branch leaf at a passing portion where vibration is not applied by each vibration applying member 131 arranged densely in the front row during traveling, vibration can be reliably given by the vibration applying member 131 arranged densely in the rear row. .

  On the other hand, the cutting blade portion 140 and the blower fan 160 are rotationally driven by the driving force from the prime mover 115, and the tea leaves are cut by the cutting blades of the cutting blade portion 140 while running on the tea tree T after the volcanic ash removal, and the tea leaves that have been cut off As shown by an arrow B in FIG. 5, the inside of the transport duct unit 150 is transported upward by the pressurized air from the blower fan 160, and further accommodated in the leaf collection container unit 170 from the outlet of the transport duct unit 150.

  Of the volcanic ash separated from the tea tree T, a part of the floating portion may pass through the transport duct unit 150 together with the cut tea leaves and be discharged into the collection container unit 170. In this case, since the foliage container part 170 is comprised from the net-like member which can ventilate, the volcanic ash (floating matter) discharged | emitted in the foliage container part 170 is as shown to arrow A2 of FIG. Then, it passes straight through the mesh of the net-like member, and is discharged out of the collection container portion 170. On the other hand, the cut tea leaves fall into the leaf collection container unit 170 as shown by an arrow B in FIG. Thus, some of the volcanic ash (floating matter) that enters the transport duct unit 150 is discharged from the leaf collection container unit 170 and separated from the harvested tea leaves.

  Thus, according to the present working machine 100, the tea leaves of the tea tree T after removing the volcanic ash can be continuously harvested while traveling while removing the volcanic ash adhering to the tea tree T while traveling. According to the vibration imparting device 130 of the working machine 100, the tip of each vibration imparting member 131 is also applied to the volcanic ash that has flowed from the leaf surface of the tea tree with the morning dew on the day of harvest due to the ash fall on the previous day and stuck to the internal branches and branches. In this way, it is possible to apply a combined vibration of the top, bottom, left, and right to the branch, or directly hit the fixed volcanic ash and effectively peel and remove it.

  When a series of work for the row of ridges is completed, the work machine 100 is turned from the edge of the ridge, and the work machine 100 is positioned with respect to the adjacent row of ridges. Then, the volcanic ash removal operation and the tea leaf harvesting operation are continuously performed while the working machine 100 is traveling at a low speed in the opposite direction again.

  The working machine 100 has the following effects.

(1) Volcanic ash and branches adhering to the branches and leaves of the tea tree T by causing the composite leaves to vibrate vertically and horizontally on the branches and leaves of the tea tree T using a large number of densely arranged vibration imparting members while running the work machine 100 It is possible to efficiently remove the volcanic ash that has adhered to the branching parts of the branches and at the same time, to cut the tea leaves from the tea tree T immediately after the removal of the foreign matter, and to store the tea leaves without the foreign matter in the collection container portion.

(2) It is not necessary to add a step of removing and collecting foreign matters in the middle of the tea production line or to add a step of washing tea leaves, so that the production cost can be reduced and the quality of tea production can be stabilized.

(3) By selecting an eccentric cam suitable for the size of the tea tree T, the amount of foreign matter adhered and the degree of sticking, the vertical and left and right vibration widths of each vibration applying member are adjusted, and foreign matter is reliably removed. Can do.

  In the above embodiment, the vibration applying device 130 is mounted in front of the main body frame 110, but may be mounted near the center (front of the cutting blade portion 140 in front of mounting) or behind the main body frame 110.

  In the above-described embodiment, the vibration applying member unit U has two rows of vibration applying members 131 arranged along the lower boom 138, but may be arranged in three or four rows. In this case, even if there is a passing portion where vibrations are not applied to the branches and leaves of the tea tree by the vibration applying member 131 in the front row during traveling, by arranging the vibration applying members 131 in the front and rear rows to be shifted from each other, Vibration can be reliably applied by the vibration applying member 131 following the rear row.

  In the above embodiment, an example in which foreign matter is removed from the branches and leaves of the tea plant T in the tea garden has been described, but the application of the present invention is not limited to this. It can also be used to remove foreign matter from other plants cultivated on the farm, such as shrubs, sakaki, azaleas and other low trees, foliage plants, herb and other horticultural plants.
