Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a directly mounted baler that can be mounted directly on a tractor, and more particularly to a directly mounted baler that can be mounted on either the front or rear of a tractor.

In order to work efficiently on slopes, it is generally advantageous to work in the direction of contour lines due to the performance of tractors and the like. However, the conventional baler consists of a trailer with two wheels, and is connected to the rear of a tractor by a single point pivot and is pulled, so it has the disadvantage that it cannot perform work in the contour direction on sloped ground.

That is, since the downward component of their weight always acts on the machine, soil, and crops, on a slope, if the slope exceeds a certain angle, both the tractor and trailer will skid down the slope. If such skidding is left unaddressed, the machine will deviate from the windrow, which is formed in a straight line, and the operator will try to correct the direction of movement of the machine. However, due to the characteristics of the single-point pivot trailer, the amount of movement of the trailer is greater than the amount of movement of the tractor, so the trailer meanderes significantly, as shown in FIG. As a result, conventional trailer-type balers cannot move straight on slopes, making it impossible to perform contour line work on slopes.

In addition, because conventional balers were connected to the rear of the tractor, the operator was unable to visually check the pick-up status while working, and therefore was unable to move the machine while aligning it with the center of the windrow. Not only was the work efficiency poor, but the workers often had to look back while working, which caused safety problems.

Furthermore, since the conventional baler was connected to the rear of the tractor, it was not possible to combine pick-up work, bundling work, and post-work such as stuffing work, resulting in poor work efficiency. In addition, conventional balers cannot combine picking up work, tying work, and previous work such as weed collection, resulting in poor work efficiency.

The present invention consists of a pick-up device, a compression device, and a bundling device, and is a baler driven by power from a tractor, in which a bale chamber is installed horizontally with respect to the traveling direction of the tractor, and a compression device and a bundling device are connected in series within the bale chamber. A directly mounted baler, characterized in that a drive device is provided in a bale case adjacent to the bale chamber, and a link that is connected and attached to a tractor is provided in the bale case, in particular, the center of the pick-up device is connected to the tractor. A guide body is provided at a point aligned with the center of the fuselage and adjacent to the side of the veil chamber opposite to the drive device, close to the rear of the pick-up device, and along the rotation locus of the tines of the pick-up device. It is an object of the present invention to solve the above-mentioned drawbacks by providing a directly mounted baler having the following features.

A directly mounted baler according to the present invention will be explained based on an embodiment shown in the drawings. A bail case 1 consisting of a horizontally long box body consists of a front part 2 and a rear part 3.
Drive devices 4a and 4b are built in, and the rear portion 3 is configured to protrude beyond the body width of the tractor 5, forming a veil chamber. The bale chamber is installed horizontally with respect to the traveling direction of the tractor 5, has a compression device 6 consisting of a plunger 6a that can freely reciprocate in the internal transverse direction, and a binding device 7, and protrudes from the width of the body of the tractor 5. One end is open and serves as a discharge port 8. In this example, the link 9 includes a top link 9a and a pair of lower links 9b, 9b.
It consists of a three-point link, one end of which is pivotally connected to the front of the tractor 5, and the other end of which is connected to the front of the bale case 2.
It is pivoted to the rear of the However, it is possible to attach it to the tractor 5 by fixing it, and in this case, the pick-up device described later is configured to be movable up and down. Further, it is also possible to use a two-point link, a four-point link, etc. as the link. There are multiple tines 10 in front of the veil chamber.
A pickup device 11 is provided. The pickup device 11 has its center centered on the tractor 5.
It is arranged so that it is aligned with the center of the fuselage.

Reference numeral 12 supplies the power from the PTO shaft 13 of the tractor 5 to the main shaft 15 via the counter wheel 14 of the drive device 4a.
16 is a rotating arm fixed to the main shaft 15; 17 is a rotating arm 16;
It is a rod pivoted to one end of the . The rod 17
is fixed to the plunger 6a at the other end. 18 is an outer fork fixed to the base of the plunger 6a and reciprocated in conjunction with the plunger 6a.

Power is transmitted to the drive device 4b via a transmission wheel 30 which is transmitted to the transmission wheel 19 of the drive device 4a by a suitable transmission member such as a chain, and drives the binding device 7 and the inner fork 21. Transmission wheel 20
The transmission wheel 22 coaxial with the transmission wheel 22 is connected to the transmission wheel 23 by appropriate means such as belt transmission, and is driven, thereby rotating the pickup device 11.

The illustrated example is a case in which the directly mounted baler according to the present invention is rear-mounted, and in this case, the guide body 24 is provided along the rotation locus of the tines 10 of the pick-up device 11 and close to the rear thereof. The guide body 2
4 is made of spring steel, is provided in a comb-teeth shape corresponding to the arrangement structure of the tines 10, and is vertically disposed to approximately the same position as the lower end of the tines 10. As shown in FIG. 4, the guide body 24 can be constructed as a unit having comb teeth protruding from a plate-like body, and can be replaced with a single touch. The guide body 24 is attached to the rear of the pick-up device 11 for collecting grass such as rice straw, etc.
This is to provide guidance and to prevent rice straw and the like from spreading, since the rotation direction of the pick-up device 11 is opposite to the traveling direction of the tractor 5. However, if the method of picking up rice straw or the like is changed appropriately, the guide body 24 is not necessarily necessary.

The directly mounted baler having the above configuration can be used by being attached to either the front or the rear of the tractor 5. The illustrated example is a rear-mounted type. Rice straw and the like picked up from the pick-up device 11 are brought to a supply port formed in the center of the side wall of the veil chamber by an outer fork 18 that reciprocates together with the plunger 6a, and taken into the veil chamber by an inner fork 21. Next, after being compressed by the compression device 6 and tied by the binding device 7, the material is discharged from the discharge port 8 to the field.

In the directly mounted baler according to the present invention, it is directly attached to the tractor 5 by the link 9, so that it is integrated with the tractor 5. When the tractor 5 is traveling alone, as shown in FIG. 5, if the front wheels are operated so as to climb up the mountain without making the center line of the machine parallel to the contour lines, the tractor 5 can travel along the contour lines. Therefore, the baler integrated with the tractor 5 can move straight on the slope and perform work in the contour direction.

Further, since the compression device 6 and the binding device 7, which require a long installation distance, are installed horizontally within the bale chamber, the length in the front and rear direction is significantly reduced compared to the conventional one. Therefore, the turning performance of the baler is improved accordingly. A compression device 6 and a binding device 7, which occupy the weight part of the baler, are installed horizontally, and drive devices 4a and 4b
is adjacent to these devices 6 and 7, and these devices 4a, 4b, 6, and 7 are arranged in the immediate vicinity of the tractor 5 and the coupling part, and the center of the pickup device 11 is located adjacent to the body of the tractor 5. Since it is arranged so as to be aligned with the center, the weight distribution is optimal for the running balance of the tractor or for mounting the baler on the front of the tractor. The pick-up device 11 is arranged so that its center coincides with the center of the body of the tractor 5, so if the tractor 5 runs across the windrow, the pick-up device 11 will naturally hit the windrow. Easy to work with and good workability. Moreover, the center of the baler's body is aligned with the center of the tractor, and there is no overhang like in the past, so it has good running performance.
Work efficiency improves. Also, the baler is tractor 5
Since the baler is pivotally connected to the baler, if it is raised during non-operations such as during transportation, it not only does not interfere with transportation, but also prevents damage to the baler. Further, since the compression device 6 and the binding device 7 are installed horizontally within the bale chamber, and the discharge port 8 formed to protrude from the body width of the tractor 5 is opened at one end of the bale chamber, various operations such as compression, binding, and discharge can be performed. can be performed continuously.

Next, the direct mounting baler according to the present invention can be mounted either in the front or in the rear, so depending on the field conditions, etc.
able to work. Therefore, the workability is good, and it is economical because it can be used for both front and rear mounting.

In the case of front loading, since the baler is attached to the front of the tractor 5 by a link 9, the pick-up state can be visually checked while working, and the baler body can be moved in alignment with the center of the windrow. Therefore, workability is improved and the operator can concentrate on driving the tractor, which is advantageous in terms of work safety. In addition, since the baler is attached to the front of the tractor, it is possible to connect bundles such as rice straw discharged from the baler by connecting a cart or the like to the rear of the tractor and connecting the baler and the cart through a guideway. It can be stored directly on a cart without letting it fall into the field. Therefore, it is possible to perform a composite operation in which the pick-up operation, the bundling operation, and the post-operation operation such as the packing operation are organically connected, and the work efficiency is significantly improved.

In the case of breech-loading, it is attached to the rear of the tractor, so by connecting the grass collection device to the front of the tractor, it is possible to combine pick-up work and tying work with front work such as grass collection, improving work efficiency. is significantly improved.

As described above, according to the directly mounted baler of the present invention, work in the contour line direction on slopes, which was conventionally impossible, is possible, and combined work is also possible, which is effective in improving work efficiency.
