Description

  The present invention relates to an electric scissor for harvesting asparagus used in a field where asparagus is cultivated, and more particularly to an electric scissor for harvesting asparagus that can be worked while stocking asparagus harvested in a standing position.

  Conventionally, in order to harvest young shoots of green asparagus in a field where edible asparagus is cultivated, when the young shoots grow to about 25 cm, they are cut and harvested from the roots of the young shoots. Therefore, in order to cut from the root for this harvest, it is necessary to bend. However, in a large field of asparagus, for example, it is necessary to harvest asparagus in units of approximately several thousand per day. For this reason, it is a very harsh labor to bend and work. As described above, when the harvesting operation is continued with the waist down, the efficiency of the harvesting operation, which was smooth at the beginning, also decreases with the passage of time.

  In addition, in order to stock the harvested asparagus, it must be stocked one by one each time it is harvested. However, such stock work by manual work one by one further deteriorates the work efficiency of asparagus harvesting. Therefore, in place of the above-mentioned harvesting work that bends the waist, it is required to harvest young asparagus shoots while standing, and at that time, the harvested asparagus is automatically stocked one by one, There is a demand for stocking in a larger harvest box together with a certain number of stocks.

  By the way, there is not yet an excellent asparagus harvesting device that can harvest young asparagus shoots in a standing position and stock them from the harvest chopsticks. However, for example, in a mower, etc., various devices have been put into practical use as portable power brush cutters that are used in a standing position, and in particular, a small engine of a power source is provided at the rear end of an operation tube hanging from a shoulder, There has been proposed a portable power brush cutter that has a rotary blade support member at the front end of the operation tube, and cuts off the vegetation by rotating the rotary blade (see, for example, Patent Document 1). However, this can cut the vegetation in a standing position with a balance of the operation tube, but the vegetation is still cut and cannot be harvested. Furthermore, no patent has been obtained for such a thing already existing.

  On the other hand, when a portable power brush cutter or the like is hung from the shoulder, vibrations caused by the engine or the like are transmitted to the shoulder, making it difficult to operate at the time of the work. Therefore, a suspension band for absorbing these vibrations has been proposed (see, for example, Patent Document 2). In this device, a rubber cord is disposed at one end of a belt of a certain length in order to absorb the movement. However, there is a patent for a device that absorbs such vibration already exists. Absent.
