Description

Technical Field

[0001] The present invention relates to a combine harvester that cuts cereal straw growing in a field and harvests cereal grains.

Background Art

[0002] A combine harvester is an agricultural machine that cuts cereal straw with a cutting and conveying device provided at the front of a traveling vehicle body, conveys it to a threshing device mounted on the traveling vehicle body for threshing, stores the cereal grains in a grain tank, and harvests them.

[0003] Moreover, Japanese Patent No. 468852 describes a plant leaf and stem cutter that cuts plant leaves and stems and harvests them in a storage tank.

[0004] The above-mentioned combine harvester is used for cereal grain harvesting work and is only used during the cereal grain harvesting period, so its annual operating period is very short.

Summary of the Invention

Problems to be Solved by the Invention

[0006] An object of the present invention is to provide the combine harvester with functions other than cereal grain harvesting to extend its operating period.

Means for Solving the Problems

[0007] The problems of the present invention are solved by the following technical means.

[0008] The invention according to claim 1 is a combine harvester which is provided with a grain straw cutting device 2 at the front part of a traveling vehicle body 1, conveys the cut grain straws to a threshing device 5 mounted on the traveling vehicle body 1 for threshing, stores the threshed grains in a grain tank 6, and harvests them. In the combine harvester, a foliage cutting device 8 for cutting the stems and leaves of weeds is attached to the upper front part of the grain straw cutting device 2, and a tillage device 7 for hoeing weeds is attached to the lower rear part of the traveling vehicle body 1.

[0009] The invention according to claim 2 is the combine harvester according to claim 1, characterized in that the foliage cutting device 8 can be lifted and lowered together with the grain straw cutting device 2.

[0010] The invention according to claim 3 is the combine harvester according to claim 1, characterized in that a monitoring sensor 12 is provided downward at the tip of a grain discharge auger 11 provided in the grain tank 6 mounted on the traveling vehicle body 1, and when an obstacle S is detected, an alarm is given to the operator of the combine harvester.

Advantages of the Invention

[0011] In the invention according to claim 1, in addition to the original function of harvesting the grains obtained by cutting and threshing the grain straws and storing them in the grain tank, the combine harvester can be used for the operation of cutting the weeds growing tall in the field with the grain straw cutting device 2 and the foliage cutting device 8 and hoeing the cut weeds into the field with the tillage device 7 provided at the rear part of the traveling vehicle body 1. The root side of the weeds is cut by the cutting blade of the grain straw cutting device 2, the high-growing tip part is cut by the foliage cutting device 8, sent to the threshing device 5 by the conveying device of the grain straw cutting device 2, shredded by the grain straw cutting device on the rear side of the threshing device 5 and discharged into the field, and then plowed in by the tillage device 7. Thus, the combine harvester can be used for weed removal other than grain harvesting, and the operation time of the combine harvester can be extended.

[0012] In the invention according to claim 2, the foliage cutting device 8 can be lifted and lowered according to the undulations of the field together with the grain straw cutting device 2, so that the weeds can be efficiently cut while being moved and hoed into the field.

[0013] In the invention according to claim 3, when weeds are growing tall, the monitoring sensor 12 provided at the tip of the grain discharge auger 11 and directed downward can detect an obstacle S hidden by the weeds in front of the machine body and notify the operator of the combine, thereby avoiding the grain straw cutting device 2 from hitting the obstacle S.

Modes for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described with reference to the examples shown in the drawings.

[0016] As shown in FIG. 1, the combine includes a grain straw cutting device 2 provided on the front side of a traveling vehicle body 1 equipped with a crawler traveling device 3 so as to be able to move up and down, and threshes grains from the cut grain straw with a threshing device 5 mounted on the traveling vehicle body 1 and stores them in a grain tank 6. A cabin 4 for an operator to board and perform operation is provided at the right front of the threshing device 5.

[0017] Near the ground of the grain straw cutting device 2, a weeding rod 10 for weeding the base of the grain straw is provided, and a clipper-type cutting blade (not shown) for cutting the base of the grain straw is provided at the rear thereof. The cut grain straw is lifted by a conveying device and fed into a threshing device 5 for threshing. The grains are sorted and transferred to a grain tank 6 for storage.

[0018] In the grain tank 6, a grain discharge auger 11 is provided so as to be able to expand and contract with undulations, and is transferred and discharged to the grain tank of a light truck parked on the ridge path.

[0019] At the upper front part of the grain straw cutting device 2, a foliage cutting device 8 provided with a star wheel blade 14 positioned between the respective weeding rods 10 in a transmission frame 9 surrounding in a loop shape is attached to the lifting frame of the grain straw cutting device 2 and moves up and down together with the grain straw cutting device 2. The star wheel blade 14 rotates by a drive shaft installed inside the transmission frame 9 to cut the foliage of weeds.

[0020] The weeds cut by the cutting blade of the grain straw cutting device 2 and the star wheel blade 14 of the foliage cutting device 8 are cut by a discharge rod cutting device 15 provided at the rear part of the threshing device 5 through the threshing device 5 and discharged to the field. A tillage device 7 mounted on the rear part of the traveling vehicle body 1 tills the field and the cut weeds are dug in. The tillage device 7 is speed-changed and driven by belt transmission from a plurality of pulleys and variable pulleys attached to the winnowing drive shaft, the second spiral shaft, etc. of the threshing device 5, and the rotational speed is detected by a sensor coupler attached to the drive shaft.

[0021] Weed cutting with this combine can be effectively used in a field where weeds have grown well due to abandonment of tillage.

[0022] In addition, if the weeding rod 10 of the grain straw cutting device 2 is removed and a discharge plate is attached instead, the combine can be used for snow removal work.

[0023] Also, as shown in Fig. 3, if a monitoring sensor 12 such as a millimeter wave sensor is provided downward at the tip of the grain discharge auger 11 to detect an obstacle S hidden in the weeds Z and an alarm is sounded to notify the operator in the cabin 4, a collision can be prevented.

[0024] Also, if the grain tank 6 and the grain discharge auger 11 are made airtight to store water, water for drinking or fire extinguishing can be transported in an emergency.

[0025] Next, an embodiment of the multi-functionalization of the tractor will be described.

[0026] Figure 4 shows that a generator mounting platform 23 for mounting a generator 22 is provided in front of the bonnet 21 of the tractor 20, and the generator 22 is driven by the engine to generate electricity so that it can be moved to a disaster area and the electricity can be utilized.

[0027] Figure 5 shows that a generator mounting platform 23 for mounting a generator 22 is provided at the rear of the tractor 20, and the generator 22 is driven by the engine to generate electricity for use.

[0028] Figure 6 shows that a generator 22 is mounted at the bottom of the tractor 20, and the generator 22 is driven by the engine to generate electricity for use.

[0029] Figure 7 shows that a generator 22 is mounted on the side of the tractor 20, and the generator 22 is driven by the engine to generate electricity for use.

[0030] Figure 8 shows that the seat guard 25 of the tractor 20 is bent backward to mount a solar panel 24, and the generated electricity is utilized.

[0031] Figure 9 shows that a solar panel 24 is mounted on a mounting base 26 surrounding the bonnet 21 of the tractor 20, and the generated electricity is utilized.
