Description

Gutter lifting means

The present invention relates to a gutter hoisting means, and more specifically, by constructing a cultivation gutter in an elevating manner to secure a work path, and to expand the cultivation area of crops and to cultivate odd or even rows of cultivation gutters at the same time. In addition, it relates to a gutter elevating means that minimizes the load on the driving unit while reducing the number of driving units by configuring the odd and even rows of cultivation gutters independently.

In general, greenhouses are agricultural facilities that artificially control the main growth environment of plants, and they can produce crops all year round because cultivation and suppression of crops are possible and can be produced all year round. It is possible to cultivate and produce special crops that are not allowed to produce high profits in the same area.

In these greenhouses, crops are cultivated in soil or hydroponic, and a work path through which workers can pass is required for sowing, cultivation management, and harvesting. In many cases, these work paths occupy more than half of the greenhouse area, which causes a problem that the cultivation area of crops is reduced.

Accordingly, a method of increasing the cultivation area by constructing the container in which the crops are grown can be elevated.

Specifically, in Japan, by installing a plurality of cultivation containers hanging side by side in the girder so as to alternately elevate the cultivation containers by using a support mechanism and a lifting mechanism, a working path is formed between the cultivation containers ascending. Plant cultivation devices have been developed.

Sprockets or pulleys that are installed at the bottom of each of the shafts, and two hangers adjacent to each other among the hangers are set as one group, and the part corresponding to the middle of the two hangers of each pair is fixed to the left or right moving pipe and fixed. The left part where the cultivation gutter is laid on the bottom with reference to the part goes downward through the sprocket or pulley left of the left position hanger, and the right part where the cultivation gutter is laid on the bottom goes down through the sprocket or pulley right of the right position hanger. It consists of a lifting member that is provided with a lifting chain or a wire that is spread across it, so that a plurality of cultivation gutters are usually placed at a certain height from the ground and suspended horizontally at regular intervals, sowing or cultivation management or When the worker needs to move in order to harvest, the driving means is operated to raise and lower the member. When moving to the left or right, a plurality of lifting members alternately rise one by one, and the next one descends, so that the plurality of cultivation gutters attached to each lifting member alternately rise and fall one by one, so that the descending cultivation There has been developed a mass cultivation device for plants to increase the amount of production by allowing the entire area of the greenhouse to be used as a cultivation area by creating a passage for workers to move between the gutters.

However, the mass cultivation device of the above-mentioned plant has a complicated structure for elevating the cultivation gutter, which is difficult to install and maintain, and the length of the elevating chain or wire is deformed by the load of the cultivation gutter, thereby shortening the service life. have.

In addition, since the odd-numbered rows and even-numbered rows of cultivators are configured to elevate in opposite directions using one driving motor, the driving motors have to be installed in correspondence to the number of cultivation pairs, and the number of driving motors is reduced due to this. There is a problem in that the cost is increased and a lot of manpower and cost are consumed for their maintenance.
