Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a baler that picks up grass, straw, etc. that has been cut and left to dry on the ground, collects it in a compression chamber, compresses it with a piston, and then bundles it. This invention relates to a pick-up device.

(b) Conventional technology Conventionally, waste straw left in the field after threshing is
Devices for picking up and packing straw are known, and a technique for arranging an air injection nozzle toward the pick-up device in order to float straw in the field is also known, as described in Japanese Utility Model Publication No. 54-36056. The technology was considered publicly known.

(c) Problems to be solved by the invention However, in the conventional technology, since the pick-up device is configured as a belt tine type, it is not possible to directly pick up straw on the ground with the tines, and once the After the straw is scooped up by the scooping plate, it is engaged with the tines and lifted up.

Therefore, the waste straw was floated using an air injection nozzle in order to make it easier to scoop it up and place it on the board.

In this invention, the pick-up device does not use a belt tine system, but is configured so that the straw placed on the ground is lifted directly by the fingers, and the material lifted by the air injection nozzle is directly connected to the fingers. It is designed so that it can be combined.

In addition, as in the past, the opening direction of the air injection nozzle faces the pick-up equipment and the operator's seat due to the scooping plate, which causes the problem that dust on the ground is blown up in the direction of the operator. Therefore, in order to improve this point, the scooping plate was eliminated and the air injection nozzle was operated forward from behind the point of action of the finger.

(d) Means for solving the problem The purpose of the present invention is as described above, and the configuration for achieving the purpose will be explained below.

The finger cam disposed inside the finger drum 45 rotates in a clockwise direction in side view while drawing a deformed rotation locus, picks up the finger 10 on the lower rotation locus, and lifts it forward. The air injection pipe 40 is moved forward toward the position where the finger 10 starts protruding below the guard drum 45.
The discharge port 40a is opened.

(E) Embodiment The purpose and structure of the present invention are as described above, and the structure and operation of the embodiment shown in the attached drawings will be explained below.

FIG. 1 is an overall side view of the self-propelled baler device, FIG. 2 is an overall plan view, FIG. 3 is an enlarged side view of the pickup device, and FIG. 4 is a plan sectional view of the air injection pipe.

As shown in FIGS. 1 and 2, the self-propelled baler device has a machine platform 9 mounted on a crawler-type traveling device 2, and a pick-up device 1 for picking up waste straw, grass clippings, etc. at the front. After being picked up by a pick-up device 1, they are collected in the center, transported vertically, compressed and packed, and then delivered from a discharge chamber 5.

The pick-up device 1 picks up waste straw and the like by rotating the finger 10 and feeds it to the cross-feeding auger 8. In order to efficiently feed the straw to the cross-feeding auger 8, the rotation is deformed by the finger cam as shown in the trajectory A shown in FIG. Draw a trajectory, finger 1
The structure is such that the waste straw is picked up on the lower circular trajectory of 0, and the waste straw is thrown into the cross-feeding auger 8 on the upper circular trajectory. The pick-up guide 12 is bent into a semicircular shape to prevent the straw caught by the pick-up device 1 from being dragged down to the bottom.

In addition, in order to prevent the pick-up device 1 from hitting the ground when traveling or working on slopes, the pick-up device 1 is made vertically movable by a hydraulic cylinder 16, and its center of rotation is aligned with the center of rotation of the transverse feed auger 8. be.

The pick-up device 1 and the transverse feed auger 8 are driven by obtaining power from the engine in the engine room 6 and transmitting it to the drive shaft 17 through the transmission case. Sprocket 20 through
, the cross-feeding auger 8 is driven, the sprocket 22 is driven via the chain 21, and the finger drum 45 is rotated.

The conveyance device 3 is provided in a protruding manner on the cover 24, and a middle part of the packer 14 is pivotally supported at the tip of a packer crank arm 15 which is pivotally supported by the drive shaft of the chain case 25. 13 are supported.

The other end of the connecting arm 13 is pivotally connected to the upper end of a pillar 11 erected on the upper surface in front of the cover 24, and this pivot shaft is connected to the vehicle crank arm 15.
This is the center of rotation of the connecting arm 13 relative to the rotation of the connecting arm 13.

With this configuration, the motorcycle crank arm 1
5 rotates, the connecting arm 13 rotates up and down, and the tip trajectory of the packer 14 becomes a deformed elliptical motion, and the waste straw collected in the center by the transverse feed auger 8 is transferred from the front end to the compression chamber by the packer 14. 4. At this time, the packer 14 performs precompression to improve the tightness of the bale.

As the above operations are repeated, waste straw accumulates in the compression chamber 4, which is detected by the star wheel sensor 38, and when a certain amount is reached, the knot is actuated from the compression chamber resistance plate 33 via the needle link 35, and the straw is compressed and packed. At this time, the hardness of the packaging is determined by rotating the resistance adjustment lever 34 and adjusting the resistance adjustment lever 36.
It can be adjusted by moving up and down.

30 is a needle crank arm, and 29 is a needle rod.

The overall configuration of the baler device is as described above, and the specific configuration of the main parts will be explained based on FIGS. 3 and 4.

In the present invention, a support rod 43 is projected forward from the track frame 42 of the crawler type traveling device 2, and an air injection pipe 40 is installed between the left and right support rods 43, 43.
is being constructed. The air injection pipe 40 has a discharge port 40a opening toward the ground surface below the front, and a piping 41 that sends compressed air sent from a compressor installed near the engine compartment 6.
are connected.

The compressed air is blown near the point of action of the top finger 10 of the pick-up device 1, and the blown straw and grass are picked up by the finger.

Also, the air injection pipe 40 is connected to the truck frame 4.
2, or support rods 43, 4 protruding from the machine stand 9, etc.
3, so the relative distance to the ground surface is always the same and it can be discharged to the optimal position on the ground surface.

In the above embodiments, a rotary type pickup device using fingers has been described, but it can also be used in other suction type or cross-flow fan type pickup devices.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, the pick-up device 1 is connected to the finger 10.
Since it is constructed with a finger drum 45, there is no scooping up below the working part of the tine, as in the case of the belt tine system, as in the conventional technology.
Since the finger 10 can be applied directly to the waste straw floated by the air injection nozzle, even the waste straw slightly lifted from the ground by the air injection nozzle can be pulled off once it is engaged with the finger 10. This makes it possible to pick up reliably.

Second, unlike the conventional technology, there is no scooping plate on the underside of the belt tine, so the air jet nozzle can be used to spray the air from the rear downward to the operating position of the finger 10. Since the dust generated by the spray nozzle can be directed in the opposite direction to the direction of the operator, it is less likely that the operator will have difficulty operating the machine due to the dust being thrown up.
