Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roll baler for turning cut materials such as hay, green grass, straw, or soybean husks into rolled bales.

[Conventional configuration and its problems] Conventionally, the roll baler 1 has the following configurations as shown in FIG.
A machine frame 4 with a bale chamber 3 formed therein is composed of a first half fixed machine frame 4a and a second half swinging machine frame 4b whose upper end is pivoted to the fixed machine frame 4a, and the tractor 2
Because it is a large machine that is towed by a truck, it has very poor workability in small fields.

[Purpose of the invention] In order to solve the above-mentioned drawbacks, the present invention aims to provide a self-propelled roll baler that is small in size and has good workability and is capable of producing good feed bales.

[Structure of the invention] The gist of the invention is that the bale chamber of a roll baler equipped with a pick-up device at the front is integrated with the drive/control device in front of the drive/control device equipped with a control operation section and an engine section. The machine frame provided therein and forming the bale chamber is composed of a lower fixed machine frame fixed on the traveling device and an upper rocker frame so as to divide the bale chamber into upper and lower halves, and the rocker frame is It is designed to be able to swing up and down to a position where a bale ejection opening is formed in the lower front part.

[Description of Embodiments] The present invention will be described below based on the embodiments shown in FIGS. 1A to 1D. The self-propelled roll baler 7 is driven by
Connect the veil chamber main body 9 to the front of the control device 8 10
It is configured as follows. The drive/control device 8 is comprised of a travel control device such as a power tiller, which includes a drive wheel 8a, a control operation section 8b, and an engine section 8c. The machine frame 11 forming the bale chamber main body 9 is
It consists of a lower fixed machine frame 11a and an upper rocking machine frame 11b which is pivoted 12 above the fixed machine frame 11a, and when the rocking machine frame 11 is in a prone state, a bail chamber 13 is formed inside, When the front part of the rocker frame 11b is raised and rocked upward, the bale chamber 13 is divided into upper and lower halves, and the rolled bale 34 (see FIG. 2) inside the bale chamber 13 can be taken out to the front. ing. A pickup device 31 is provided at the front of the fixed machine frame 11a, and height-adjustable auxiliary front wheels 30, 30 are provided protruding from both sides, and together with the drive wheels 8a, a traveling device 37 is configured. ing. As shown in FIG.

The carry-in device 15 connects conveyor chains 15a, 15a stretched on the left and right with conveyor rods 15b, 15b... (second
It consists of a known carrying-in device, which is made by attaching a (see figure) to a pitch as appropriate. The bundling conveyance device 16 also includes conveyor bars 16b, 16b... (second
It is constructed from a known bundling conveyance device, which is constructed by attaching a bundle (see figure) to a suitable pitch. The left and right inner walls of the bale chamber 13 are formed of pressing side plates 17, 17, as shown in FIG.

Note that the pressing side plate 17 is configured as follows, if necessary. That is, the pressing side plate 17 is attached to the fixing machine frame 11a so as to freely rotate concentrically with the left-right center line B of the bale chamber 13 and to be biased to slide inward along the center line B. The structure that urges the pressing plate 17 inward (arrow C direction) is such that the base 19 is moved between the pressing plate 17 and the fixing machine frame 11a.
A gap 2 between the base plate 19 and the pressing side plate 17 is pivotally supported on the fixed frame 11a so as to be freely rotatable between the inner surface of the base plate 19 and concentrically with the left-right center line B.
Compression springs 21, 21, . . An annular peripheral portion 19 of the base 19
a is a conveyance chain 15a of the carrying-in device 15 and a conveyance chain 16a of the bundling conveyance device 16;
It serves as a guide rail. The outer peripheral edge portion 17a of the pressing side plate 17 is formed into an outwardly curved annular shape, and covers the gap portion 22, and is connected to the conveying surface of the carrying-in device 15 and the conveying surface of the bundling conveying device 16. Relief gaps 23, 23 are formed to prevent the cuttings from getting entangled. The rotating shaft 17b of the pressing side plate 17 has its distal end protruding to the outside of the fixed machine frame 11a, and the engaging element 25 of the retracting means 27 is slidably inserted into the distal end thereof as necessary. At the same time, an adjustment screw 26 is screwed onto the shaft end, and the compression springs 21, 21
It is possible to adjust the initial repulsive force of...
The engaging element 25 has an annular groove 25a formed on its outer circumferential surface, and engages a roller 28a of an operating lever 28 pivotally supported on the stationary frame 11a into the annular groove 25a, so that the operating wire 36 can be pulled. Accordingly, the pressing side plate 17 is forced to move outward along the rotation axis 17b. The operating wire 36 is connected to the rocker frame 1 constituting the bail chamber 13.
It is preferable that it be pulled in conjunction with the rocking rise of 1b (see FIG. 1D). The fixed machine frame 1
1a, a rotating shaft 17b of the pressing plate 17 is located at a proper position.
Detection means 29 consisting of a limit switch or the like is installed as necessary for detecting the position of and detecting that a predetermined pressing force has been generated on the pressing side plate 17 that presses the side surface of the rolled bale 34. Note that both the left and right inner walls of the bale chamber 13 are not formed from the pressing side plates 17, and although not shown, one of the inner walls is made to be the pressing side plate 17 and the other inner wall is a fixed wall similar to the conventional one. Of course, this is also possible. FIG. 3 shows an embodiment of another aspect of the pressing plate 17, and the difference from the embodiment shown in FIG. 2 is that the base plate 19 is not provided;
A compression spring 21' and a spring seat 33 with a thrust metal are inserted into the rotating shaft 17b of the pressing side plate 17, and the repulsive force directly received from the fixed machine frame 11a is transferred to the pressing side plate 1.

In FIG. 1C, 35 is a twine supply device.
At the terminal end of the bundling conveyance device 16, a roll 32 for preventing winding up is provided so as to be forcibly rotated in the direction of arrow D, if necessary.

[Function] Next, the function of the self-propelled roll baler according to the present invention will be explained. As shown in FIG. 1C, the harvested material 8 is picked up by a pick-up device 31 and supplied to a carry-in device 15. The harvested material 6 guided into the bale chamber 13 is bundled into a roll by a carry-in device 15 and a bundling conveyance device 16. The rolled bale 34 that has been bound by twining (not shown) or the like is moved to the swinging frame 11 as shown in FIG. 1D.
Bale chamber 1 divided into upper and lower halves by the rocking rise of b
3 is discharged to the outside by the reverse drive of the carrying-in device 15 or the like.

[Effects of the invention] As detailed above, the self-propelled roll baler according to the invention has the following practical effects.

Since the drive/traveling mechanism and the bale chamber body are constructed as an integrated unit, it is possible to make the machine more compact, thereby improving work efficiency in small fields.

Since a pick-up device is provided in front of the drive/control device, the harvested material is picked up and carried into the bale room without being stepped on by the operator, and becomes a good bale for feed.

The rolled bale in the bale chamber can be taken out forward by swinging the front part of the rocking frame upward, so that the rolled bale can be taken out easily and work efficiency can be improved.
