Description

Seedling machine {weeder}

The present invention relates to a seedling trimmer, and more particularly, to a seedling trimmer that can be recovered by lifting a cutter cut at the time of sorting and lightening.

Generally, farmland is planted with various crops, and it is managed to grow well. After a certain period of time, it is harvested. However, if you become too laughable before the harvest and grow tall, you may end up unnecessarily consuming nutrients and adversely affect growth. In addition, when crops planted on a large land grow unevenly, crops are cut at a constant height for appearance, and a mowing machine is used.

Korean Patent Laid-Open Publication No. 2015-0037188 discloses a seedling sorting machine. The posted seedling arranger is installed on the frame and placed on the ground, and is provided with a pair of left and right wheels spaced apart from each other by a predetermined distance for rotation; A cutter module coupled to one side of the frame, the handle having a handle on one side; Wherein the cutter module is coupled to the feeder and the cutter module is vertically elevated and lowered together with the feeder; And a drive module connected to the wheel and rotating the cutter module as the wheel rotates.

A lawn mower is posted in the Japanese Patent Registration No. 04497078, and Korean Patent Registration No. 2008-0089020 discloses a harvesting device for harvester using power of farm machinery. Is published. U.S. Patent No. 11069899 discloses a home chopper and lawn mower with home chopper. Patent registration No. 15847050 discloses a tractor lawn mower equipped with tiller trimming means.

Since the seedling arrangements or lawn mowers constructed as described above are relatively heavy and have a structure that is moved and driven by the power, they are subject to a great deal of work environment, and the cut residues remain on the base plate, . Even if a unit for recovering the remnants is provided, there is a problem that frequent occurrence of troubles due to blowing of air is caused due to the structure in which the air is blown by the rotational force of the cutter cut in the blower and is blown.

[

As shown in FIGS. 4 and 5, the cutting unit 30 includes a plurality of first cutting edges 31, which are provided at a predetermined interval in a moving direction, The first cutting member 32 and the first cutting member 32 are guided by a guide portion (not shown) so as to be slidably installed in close contact with each other. The first cutting member 32 intersects with the first cutting edge 31, And a second cutting member 36 having a second cutting blade 35 for cutting the second cutting blade 36. The second cutting blade 36 is connected to a driving shaft of a blower to be described later by a belt, And a feed drive unit 37. The reciprocating movement driving unit 37 includes a first eccentric member 33 provided at one end of the first cutting member 32 and having a first eccentric guide hole 33a into which the eccentric cam is inserted, A second eccentric member 38 provided at one end of the member 36 and formed with a second eccentric guide hole 38a into which the eccentric cam is inserted and a second eccentric member 38 provided at one side of the first and second eccentric members 33, An eccentric cam 39 inserted into the eccentric guide hole 38a and rotatably coupled to the eccentric cam 39 and connected to the drive shaft of the blower by a belt do. The reciprocating feed driving unit is not limited to the above-described embodiment, but may be a structure capable of feeding the first cutting member 32 and the second cutting member 36 relatively.

The rotation shaft 39a is rotated by the rotation of the driving shaft of the blower so that the eccentric cam is rotated inside the eccentric guide hole to reciprocally rotate the second cutting member 36 with respect to the first cutting member 32. [

The collecting unit 50 collects the seedlings cut by the cutting unit 30. The collecting unit 50 includes a blower 51 installed in the subframe 18 and a seedling cut in connection with the blower 51 And a spraying nozzle 52 for spraying the collected water into the collecting bag 100 located at the rear. The blower 51 is disposed so that the rotating shaft can be vertically installed. The frame 11 is provided with a bracket 41 capable of height adjustment and angle adjustment and a driving engine 42 as a driving unit 40 is installed in the bracket 41. The power shaft of the driving engine 42 is connected to the driving shaft 51a of the blower 51 by the flexible wire 43 to transmit the rotational force. A drive pulley for transmitting power to the rotary shaft of the cutting unit is installed at an end of the rotary shaft of the blower 51.

The spray nozzle 52 includes a main blowing pipe 52a connected to the blower 51 and disposed in parallel with the first and second cutting members 32 and 36 of the cutting unit 30, Leaves and branches that are cut by the first and second cutting members 32 and 36 and extend to the first and second cutting members 32 and 36 from the bag supporting portion 15a And branching nozzles 52b for discharging the collected water to the collecting bag 100 side. The branching nozzles 52b are provided with extension portions 52c extending toward the first and second cutting members 32 and 36 and first and second cutting members 32 and 36 provided at the end of the extension portion. And a jetting section 52d formed on the upper surface thereof. And a guide plate 60 for guiding the seedlings cut by the cutting unit 30 to the collecting bag side is installed in the subframe.

In order to sort seedlings by using the seedling arranging apparatus according to the present invention constructed as described above, the collecting bag 100 is mounted on the bag supporting unit 15, and the main wheel 12 is rotated So that it can be placed in the goal between the growing dikes. In this state, the height of the subframe 18, that is, the height of the cutting unit 30, is adjusted using the handle of the height adjusting means 20 to adjust the length for sorting the seedlings.

When the adjustment is completed as described above, the worker tows the seedling machine 10 and advances it. In this way, the seedlings are moved to the side of the first and second cutting blade members 32 and 36 of the cutting unit 30 and are cut by the first and second cutting blades 31 and 35, Leaves and stems are severed. The cut leaves and stems or branches are fed into the collecting bag 100 by the spray nozzles 52 of the packaging unit. High pressure air blown through the blower 51 is blown to the main blowing pipe 52a and air blown to the main blowing pipe 52a is blown through the respective branch nozzles 52b to collect the cut leaves and stems And transported to the bag 100. The seedlings are arranged at a constant height in the above-mentioned successive ups.

Since the structure of the seedling arranging unit as described above is relatively simple and lightweight, it is easy to carry, and it is possible to adjust the height of the cutting unit for sorting seedlings and to cut to a uniform height, Can be reduced. Also, it is possible to collect collected leaves, stems, and the like, thereby preventing the growth of seedlings from being hindered.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

The seedling arranger of the present invention can be applied not only to planting seedling seedlings but also to weeding work such as lawn mowing.
