Description

  The present invention relates to volume reduction of a roll bale that is subjected to volume reduction processing in order to reduce the labor and cost of transporting and transporting the roll bale that is compressed and packed into a roll by a roll baler and discharged. The present invention relates to a method and a roll bale volume reduction device used for carrying out this volume reduction method.

  A roll bale formed and packed with a roll baler is a continuous belt-like state in which the roll baler picks up pasture, rice straw, etc. that have been cut down in the field by a pick-up device equipped on the front end of the machine. Then, it is sent to the bale molding room equipped at the rear of the machine, where it is wound into a roll and compressed, and when it is formed into a roll of a predetermined diameter, the twain or net is drawn out and packed by winding and tightening it. When the packing is finished, the roll bale is discharged to the rear of the machine body by opening the roll forming chamber.

  This roll bale is formed by the roll baler and the grass forming process is carried out while picking up the grass that is left on the field scene while the machine is running. It is released to the surface and left unattended. And whether it is picked up at an appropriate time after finishing the bale forming work by the roll baler and temporarily accumulated in an accumulation place such as a storage building, from where it is taken out as feed for daily livestock and consumed for feeding Or sold for the purpose of using it as a bedding. The shipping of roll balers to be sold is usually carried out by truck.

  This roll bale is formed into a volume having a diameter of 1 m and a width (length in the radial direction) of 1 m, and the weight of one roll bale thus formed varies depending on the type of the harvested product. However, it is in the range of 100 kg to 200 kg.

  When a 4 ton truck is used for transportation on a truck bed, 40 trucks are used for the truck bale if the weight of the roll bale is 100 kg. If the roll bale is 200 kg, 20 pieces can be loaded on the carrier and transported. However, in reality, the roll bale is formed as a cylindrical bulk having a diameter of 1 m and a width of 1 m, and due to the restriction due to this bulk, there is a sufficient margin for the weight allowed for the truck. Even if there is, there are legal restrictions on the length, width and height of the truck bed, so it is not possible to load up to the number of accumulated weights corresponding to the loaded weight. It is expected to be loaded and transported.

  For this reason, this roll bale has a problem of poor transport efficiency. This problem should be solved by compressing the molded roll bale to reduce the volume and reduce the bulk. However, the roll bale formed with a roll baler is a bale in the molding chamber where harvests such as grass, rice straw, and corn foliage are fed continuously into the bale forming room equipped on the roll baler body. While being rolled into a roll by a molding apparatus and receiving pressure from the outer peripheral side, it is sequentially wound and compressed by tightening, and further compression-molded by winding and tightening a twain net. It is difficult to compress this to further reduce the volume.

  The roll baler is equipped with a pressurizing device for pressurizing and compressing the roll bale to be molded in the molding chamber so that the degree of pressurization can be adjusted. It may be possible to compress and reduce the roll bale by adjusting this to the high pressure side. The volume is 1 m in diameter and 1 m in width. At this time, the increase in the weight of the roll bale is not so much, and the weight per piece stays within the range of 100 kg to 200 kg described above.

  Therefore, even if compressed to high pressure using the pressure compression means equipped in the roll baler, it does not improve the restrictions on the number of loads and the transportation efficiency during transportation by truck, leaving a problem. Shall be.

  The problem to be solved in the present invention is to increase the number of roll balers loaded on the truck bed when the roll balers formed and discharged by the roll baler are loaded on the truck bed and transported. An object of the present invention is to provide a means for effectively reducing the volume of a roll bale for loading up to the limit of the load weight of a truck.

As a means for solving the above-mentioned problems, in the present invention, a roll is compressed and formed on a roll by a bale forming device in a forming chamber provided in the roll baler, and the outer peripheral side is tightly tightened by a twain or a net and released from the forming chamber. The rolled bale is placed on the support stand in an upright position in which the axial direction is the vertical direction, and a pressure plate that is lifted and lowered by the lifting device is brought into contact with the upper end surface in the axial direction of the roll bale, When the pressure plate is lowered by operation, the roll bale is pressed and compressed in the axial direction, and when the roll bale is crushed and reduced in volume in the axial direction, it is fixed in the axial direction with wires, ropes, metal fittings, etc. Next, a method for reducing the volume of the formed roll bale is proposed, in which the volume of the roll bale is reduced by releasing the pressure applied to the pressure plate. .
Along with this, a bale storage chamber is provided in which a bale storage chamber is provided in which a roll bale with the axial direction as the up-down direction is stored, and the bottom is supported on the upper surface side. A plate-shaped machine frame having an opening for opening and closing the roll bale and an opening / closing door for opening and closing the opening so as to be freely opened and closed, and an upper surface side opening upward; On the upper surface side of the machine frame, a pressure plate whose lower surface abuts against the upper end wall surface of the roll bale by descending is disposed so as to be movable up and down, and the upper surface side of the pressure plate is placed on the upper part of the machine frame. A roll bale volume reduction device is formed which is connected to the lower end side of the lifting mechanism that is supported on a standing support machine frame, and is mounted with an operating device that moves the lifting mechanism up and down on the outer surface side of the machine frame. To do.

  The means of the present invention reduces the volume of the roll bale that has been compressed and molded and wound and packed by a twain net by compressing and compressing it in the axial direction and crushing in that direction. Since the volume of the roll bale is reduced by a few tens of percent because the volume is reduced by fixing and holding in a state of volume reduction by tight binding with ropes and metal fittings, when loading on the truck bed In addition, the number of loadings can be increased, and the truck can be loaded up to the limit weight of the truck loading, so that the efficiency of truck transportation can be improved and the transportation cost can be reduced.

As a vertical posture in which the axial direction is the vertical direction, it is placed on a flat support base so that one end face in the axial direction is joined to the top face of the support base as a bottom surface to become the top surface. A pressure plate that is raised and lowered by an elevator is placed on the other end surface, and the roll bale is pressed and compressed in the axial direction by operating the elevator, and when it is compressed, it is bound with ropes, wires, and metal fittings. Then, fixing is performed so as not to restore, and the pressurization of the pressure plate is released.

  The volume reduction performed by pressurizing the roll bale in the axial direction is based on knowledge obtained through various studies to solve the above-described problems. A roll bale is formed by being pressurized and compressed in a roll baler molding chamber, and the pressure and compression is radial from the circumferential surface of the roll bale and is axially pressurized and compressed.
