The present invention relates to a self-supporting grass harvesting device, and more particularly, to a self-supporting grass harvesting device for harvesting the grass at the same time to form a bale using the harvested grasses.

As the livestock industry expands considerably and the importance of cultivation of grasses and feed crops increases, the cultivation area of grasses is expanding. Important feed crops include corn, sudangrass, rye, and Italian rice. Perennial grasses are cultivated with orchardgrass and tolfescue.

These grasses are harvested using a grass harvester and fed as green food, or mowed and dried at high nutrient yields to be prepared or fed for hay and silage.

Pasture harvester is an agricultural device for harvesting grasses by attaching them to agricultural tractors. Conventional forage harvesters cut and cut grasses, which are raw materials of silage, and blow them into a tractor (tractor) by wind power. It is a lifting type and is divided into a towing type and a self-propelled or a mower type and a flail type.

Since the conventional grass harvester performs only a role of cutting and cutting grass, it must be connected to a separate tractor, etc. in order to transport the harvested grass, which requires a user's effort to connect with the tractor.

Pasture harvested by the grass harvester is transported using a tractor and filled with grass in a suitable container or silo in order to minimize loss during long-term storage and storage, and then fermented to form silage.

Silage refers to feeds that give shelf life by a biochemical method called fermentation. Silage is a material made from grass, usually silage. Silage is a fermentation fermentation of lactic acid bacteria that inhibits the degradation of other decaying bacteria. Also called every second.

Silage is less affected by the weather than hay, it is easy to be mechanized and relatively low in storage loss, so it is economical and easy to organize, so it is suitable for large-scale farming, it is possible to grow various crops, relatively safe and palatable. It is a high storage way

However, because silage is difficult to distribute, it is less marketable than hay, has to be paid immediately after being taken out of the container, additional expenses are required for transportation, large storage volume, and large loss due to storage technology. .

These silages include mechanical losses from harvest, chemical loss from respiration or fermentation of plants, fermentation loss from aerobic microbial activity during storage or feeding, and effusion loss from high moisture content in the material. There is a problem that a loss of at least 7% compared to the raw material can be as much as 40% due to losses from immaturity of the preparation technology.

Accordingly, the present invention is to solve this conventional problem, an object of the present invention is to provide a self-supporting grass harvesting device to form a bale by cutting the grass to a certain size immediately after harvesting to facilitate the treatment of grasses and Together we want to minimize the loss of grasses.

Other objects and features of the present invention will be more clearly understood through the preferred embodiments described below.

According to the present invention, an engine is mounted, a vehicle unit having a steering device, an inlet unit installed at the front end of the vehicle unit to pull grasses, a cutting unit installed in close proximity to the inlet unit at the front of the vehicle unit, the vehicle unit A baler unit installed between the cutting unit and the baler unit to form a bale with the cut grass installed in the rear part of the conveyor unit for transporting the grass cut through the cutting unit to the baler unit, and the cutting unit includes a drawing unit. Self-supporting grass harvesting, characterized in that the cutting roller pair rotates to face each other with the grasses interposed therebetween, and one cutting blade is installed on the side of the cutting roller in the height direction to cut the grass entering through the inlet unit to a certain length. An apparatus is provided.

Further, the inlet unit is composed of a plurality of chain gears interposed in at least one pair of frames opposed to each other in the horizontal direction, and at least one pair of chains rotated in different directions by the chain gears.

Preferably, both ends may further include a lying down piece that is connected to the upper surface of the frame so that the inlet unit lays down the grass so as to easily attract the grass.

Figure 4 is a state diagram used for explaining the self-supporting grass harvesting device according to the present invention, with reference to the accompanying drawings will be described a method of operation of the self-supporting grass harvesting device according to the present invention.

The user boards the driver's seat and moves the grass harvesting device according to the present invention to the grass growing place.

The chain 24 of the inlet unit 20 is rotated by the user's operation, and the grasses in front of the inlet unit 20 are drawn in. At this time, the grass is laid down by the lying down piece 25 to deepen the inside of the vehicle unit 10. Drawn in.

Grasses drawn by the inlet unit 20 are further drawn into the inside of the vehicle unit 10 by the rotation of the inlet roller 32, and the grass is cut by the cutting blade 39 while the cutting roller 34 rotates. do.

Grasses cut and harvested by the cutting unit 30 are loaded on the conveyor unit 40 and moved to the baler unit 60, whereby the bales of the reversing unit 50 are uniformly spread to facilitate the baler work. .

Grasses are transferred to the baler unit 60 through the conveying path 42 inclined toward the baler unit 60, and the grasses are compressed with each other as the rollers 62 rotate to form a circular bale 70. .

When the inner space of the baler unit 60 is filled with grasses, the door 64 is opened and the bale 70 is discharged to the outside.

After harvesting the grass, the user can easily harvest the grass by transporting the bale formed through the grass harvesting apparatus of the present invention to transport to the storage.

Overall, when harvesting the grass by applying the grass harvesting device according to the present invention, the process of harvesting the grass to form a bale is made in one device, the inconvenience of using a conventional grass harvesting device connected to the tractor Eliminate and require no extra equipment and effort to harvest harvested grasses.

In addition, as the bales are formed and stored immediately after harvesting, it is possible to minimize the loss of grass caused by silage formation.

Although the above has been described based on the preferred embodiment of the present invention, it can be appropriately changed or modified by those skilled in the art without departing from the scope of the present invention. It is natural that such changes or modifications fall within the scope of the present invention without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims of the patent described below.

As described above, the self-supporting grass harvesting device according to the present invention is a process of forming a bale with the harvested grass after harvesting the grass with a single device, it is possible to reduce the user's time and effort In addition, it is economical because it does not require several farming equipment such as a harvesting device and a baler, and there is an advantage in that it is not necessary to purchase various equipment even in a small farm where it is difficult to purchase expensive equipment.

In addition, since the bales are formed immediately after harvesting the grass, it is possible to minimize the loss of grass that may occur during silage formation has the advantage of minimizing the waste of resources.

Moreover, there is an advantage that can be used in a lot of watery arable land can grow grass without difficulty even in a farmhouse that used rice farming.
