Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This proposal relates to a device that can easily cut and harvest only the head flowers of crops such as sunflowers where the crop head is high.

[0002]

[Prior Art]

 Conventionally, when harvesting crops such as sunflowers where the head of the crop is high, only head flowers are manually harvested with a sickle.

[0003]

[Problems to be solved by the device]

 Regarding the conventional technology, the following problems can be pointed out. Since the harvesting efficiency of human power is as low as about 2 are per day, it is impossible to increase the cultivation area. Since the cut head is naturally dried and then threshed by human power, the labor burden is large and inefficient. Of course, harvesting is possible without equipping this combine harvester with a normal combine harvester, but the reality is that the grain loss is 20% or more. The present application has been made in view of such problems of the conventional technique, and an object of the present application is to provide a device capable of solving the above problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, in the case of the present application, an appropriate number of cutting knives 2D arranged in parallel at the tip of the bottom plate in the horizontal direction with respect to the advancing direction, and a rotating reel 2J and the like which are vertically movable are arranged on the upper surface of the cutting knives. In the front part of the mowing section 2, left and right vertical sward plates 3 for separating the heads of napped crops into left and right are serially arranged, and a horizontal sward plate for separating the heads of napped crops into left and right between the left and right vertical sward plates. 4 is arranged so that the support angle can be adjusted with respect to the cutting knife, and a wire mesh 5B is stretched on the front surface of a frame 5A having a horizontally long rectangular front shape. The upper part of the side surface is supported between the grass plates 3 with a slight inclination in the traveling direction, and the position and support angle of the alignment plate 5 in the front-rear direction are adjustable. It is a reaper.

[0005]

【Example】

 Examples will be described with reference to the drawings. 1 is a crop head grain cutting device of the present invention, which is mounted on a known cutting unit 2 having the following configuration. Therefore, the cutting unit 2 is a cutting frame 2C composed of left and right sidewalls 2A and a bottom plate 2B arranged on the left and right with respect to the traveling direction, and an appropriate cutting unit 2 which is arranged in parallel at the tip of the bottom plate in the traveling direction. Several known cutting knives 2D, a known conveyor 2E rotatably arranged behind this cutting knife, a known retracting auger 2F rotatably arranged behind this conveyor, and this retractor It is composed of a feed drum 2G rotatably arranged behind the auger.

[0006] Furthermore, a right and left supporting rods 2H having a fulcrum 2H1 at a predetermined position on the mowing frame 2C, and a known rotating reel 2J are rotatably supported between these supporting rods. 2J1 is a reel tine. 2J2 is a reel fulcrum. The supporting rod 2H is constructed so as to be entirely moved up and down by a vertical hydraulic hoist 2H2 arranged between the supporting rod 2H and the cutting frame 2C. Such a mowing section 2 is mounted on a tractor, a combine (not shown), etc., and its supporting height is freely adjustable by a vertical hydraulic hoist 2K. Therefore, the rotary reel 2J pulls the crop head in the direction opposite to the traveling direction, and the reel tine 2J1 sends the crop head cut by the cutting knife 2D to the conveyor 2E. The conveyor 2E is a device for feeding the crop head to the pulling auger 2F, and the pulling auger pulls the crop head, and the crop comes to the position f and is fed to the main body (not shown) by the feed drum 2G. Become.

[0007] Thus, 3 is a left and right vertical sward plate continuously provided at the tips of the left and right side walls 2A in the traveling direction, and separates the napped crop heads into left and right. 4 is a horizontal sward plate arranged between the left and right vertical sward plates, which is located in the middle of the entire length of the crop and vertically aligns the crops. In the illustrated case, there are seven sheets in total, and the left and right sides have a width half that of the middle five sheets. The arrangement is uniform, and the tip angles are 25 degrees on the right side and 30 degrees on the left side of the center line when viewed from the upper plane.

Referring to FIG. 3, the horizontal sward plate 4 is connected to the rear side 4A fixed to the cutting frame 2C by a fixed point 4A1 by a pin 4B, and the horizontal sward plate and the rear base are T-shaped. It is connected by a metal mold 4C. Further, this T-shaped metal fitting can be adjusted by moving the outer nut 4C1 and the inner nut 4C2 to vertically move the supporting angle of the lateral grass plate 4 with respect to the cutting knife 2D.

Reference numeral 5 denotes an alignment plate formed by stretching a wire mesh 5B on the front surface of a frame 5A having a horizontally long rectangular front shape. It is supported in a tilted state. The alignment plate 5 is constructed so that the position in the front-rear direction and the support angle can be adjusted. That is, the auxiliary support rods 5C are connected to the tip ends of the left and right support rods 2H so as to be adjustable in advance and retreat with respect to the support rods 2H via the in-and-out fixing points 5C1. The aligning plate 5 is connected via a horizontal pin 5C2 orthogonal to the direction, and the lower end of a connecting rod 5C4 connected to an upper portion of the aligning plate 5 via a horizontal pin 5C3 orthogonal to the traveling direction is an auxiliary supporting rod. It is connected to the middle portion of 5C via an alignment plate angle adjusting point 5C5. When the aligning plate 5 hits the crop head and the entire apparatus advances (to the left), the head moves from a to b in the directions c to d and e while touching the wire mesh 5B. The alignment plate 5 can change its angle back and forth about the horizontal pin 5C2 by the movement of the alignment plate angle adjusting point 5C5, and the alignment plate 5 can change its supporting position back and forth by the movement of the insertion / removal fixing point 5C1.

[Effect of the device]

 1. The head height can be made uniform. That is, since the heights of the crop heads are not uniform, the heads are aligned with the target height by pushing the alignment plate to proceed. 2. The head columns can be aligned. That is, since the heads of the crops are horizontal, the heads are evenly distributed and aligned in the direction of travel. 3. Can cut under the head of the head. That is, the aligned heads are cut in a hanging state as the cutting device of the present invention advances. 4. The head can be sent. That is, the cutting head is supplied to the reaping device of the present application by the conveyor. 5. It can be freely attached and detached as an attachment to an existing combine combine that has already been introduced. In other words, when harvesting the grain on the head of a high-height crop (about 1.8 m), it cannot be harvested unless the device of the present application is installed. This is because a thick, high-moisture material (stem) cannot be sufficiently threshed and sorted if it enters the machine with grain. In the case of rice and wheat that can be cut off from the ground, the device of the present application is removed and used. When attached to an existing combine harvester that has already been introduced, it can contribute to an increase in the area of head crops. By the way, when harvesting with a combine with a cutting width of 2.0 m, the harvesting efficiency is about 20 a / h, which is about 40 times the human power. It is also possible to harvest (shear) quality head grain with low plant height (short culm sunflower to a length of about 1.0 m). This is because the angle of the horizontal grass board 4 can be adjusted.
