Description

[Detailed Description of the Invention] This invention efficiently mechanically compresses the grass, grass, etc. that is dried on the ground after mowing the grass, etc. of golf courses, pastures, etc. using a mower etc. Concerning a new packing machine.

BACKGROUND OF THE INVENTION As working machines for compressing and packing dried lawns, pastures, etc., there are known machines such as the Heeless, Hebera, and Tight Baler, and various improvements have been made.

For example, as disclosed in Japanese Patent Publication No. 42-6136, a conveyor device for picking up is provided in the front part of the traveling vehicle body in a downward direction, and the grass etc. conveyed by the conveyor device is rotated around the vertical axis. Some grasses are fed into the upper part of a rotating auger screw, and the grass is preliminarily compressed by the auger screw and fed into a ram, where the ram forms a compressed mass of grass.

However, in this conventional example, the compression molding of grass is performed by a ram that slides in the front and back directions, so the device has to be large in the front and back direction in order to ensure the stroke of the ram, and the conveyor device is tilted downward in the front and back. Therefore, there is a problem that the length of the device in the front and back direction is too long, and since the conveyor device is so-called exposed, there is a danger that humans and livestock may become entangled, and the grass is blown away by the wind during transportation. There was also a fear.

Furthermore, in the conventional example, the compression-molded grass is fed into a die and granulated, which is not a so-called big baler, making subsequent handling relatively difficult.

This invention was devised in view of the above circumstances, and its purpose is to effectively dry grass, grass, etc. by attaching it to a traveling vehicle such as a tractor and driving it. The aim is to provide an inexpensive device that can be picked up and compressed and packed into a large-capacity package, and that the overall device can be designed compactly and has a low failure rate.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The shift fork 34 is engaged, and the dog clutch 32 is normally engaged, transmitting power to the rotating shaft 26,
．． 14, when the amount of compression of the grass, etc. reaches its limit, the shifter 31 is forcibly moved upward via the switching spring and shift fork 34, so that even if the pulley 30 rotates, the auger 24,
The drive of 25 is stopped.

Note that the pulley 30 may be directly connected to the rotating shaft 26 without using the above configuration.

Container 13.14 and auger casing 19.20
A chute 35 is attached to the lower frame member 7 in front of the lower frame member 7 in a forward downward posture, and the chute 35 has a downwardly opening pickup chamber 36 at the lower part, and the subsequent path 37 gradually tapers to the tip (upper part). has an input port 38 facing the socket 21.

In addition, in the example shown, the container 13.14 and the casing 1
9.20 is because the left and right distribution is paralleled as a gap,
At the input port 38, a triangular support base 39 fixed to the canopy that also serves as a guide is used to drop grass, etc. exclusively into the casing 20 when a switching shutter 40 that rotates around a vertical axis reaches the dotted line state in FIG. Therefore, the same shutter 40
The switching mechanism can be implemented electrically or mechanically.

In the pick-up chamber 36 of the chute 35, a rotary shaft 42, which is supported by the lower frame member 7 etc. via a bearing 41, crosses the same chamber 36, and a pick-up body 43 consisting of a large number of brushes etc. is implanted on this shaft 42. The coaxial shaft 42 and the pickup body 43 constitute a pickup member 44, which is actively rotated clockwise in FIG.

Note that the front inner wall of the pickup chamber 36 is a guide wall 45 having a tapered and curved surface shape.

In addition, in the figure, 46 is an opening/closing mechanism for the opening/closing door 16, which is composed of hydraulic cylinders, piston rods, etc., and the cylinders are each pivoted to the casing 19920, and the piston rod is connected to the opening/closing door 16.16. The opening/closing doors 16,16 are respectively pivotally supported, and are configured to close when the rods are extended and open when the rods are retracted.

Reference numeral 47 designates an extrusion mechanism for compression packed products, in which one end of the cylinder is pivotally supported on the back wall of the chute 35, and the tip of the piston rod is movably provided inside the front wall of the container 13.14. It is constructed by being pivoted to a plate 48, and the pivot portion is a long hole 49.

The opening/closing mechanism 46 and the push-out mechanism 4γ are electrically related to each other, and after the former performs the opening operation, the latter performs the push-out operation.

Next, to explain the power transmission system, a gear box 50 is provided at the front center of the lower frame member 7, and its input shaft and PTO
A power transmission shaft 51 is interposed between the shaft 2 and the shaft 2 .

The output shaft 52 of the gear box 50 is extended in the lateral direction, and its extended portion is pivotally supported by a bearing 53.

A pulley 54 is fixed to the extended end of the output shaft 52, and a belt 56 is stretched between this pulley 54 and a pulley 55 fixed to the rotating shaft 42, so that the pickup member 44
can be driven.

A gear box 57 is provided at the front central part of the upper frame member 6,
A pulley 58 is fixed to the input shaft, a belt 60 is stretched between the pulley 59 and the pulley 58 fixed to the output shaft 52, and a pulley 61 is fixed to the output shaft of the gear box 57.
is fixedly installed, and this pulley 61 and the above-mentioned pulley 30,
A belt 62 is stretched around the auger 30 as shown in the second figure, thereby allowing the auger 24, 25 to rotate about its longitudinal axis.

To explain the operation of the embodiment of the present invention configured as described above, when the tractor body 1 moves forward, the power derived from the PTO shaft 2 drives the pickup member 44 and the augers 24 and 25 via the transmission mechanism. Meanwhile, the compression packing machine 3 is towed.

Grass, grass, dust, etc. that are dried on the ground at golf courses, meadows, etc. are swept up by the rotation of the pick-up body 43 of the pick-up member 44, enter the chute 35 along the front guide wall 45, and are then picked up by the pick-up body 43. In this case, the path 37 of the chute 35 is shaped so that it follows the direction in which the grass, etc. is discharged from the pick-up body 43, that is, the direction of the centrifugal force at the time of discharge, and Because of the tapered shape, continuously raked grass, etc. can be smoothly and reliably conveyed to the input port 38 of the chute 35.

During this transportation, the grass, etc. will not be blown away even if it is hit by wind and will be transported reliably, and since the pickup body 43 is stored in the pickup chamber 36, there is no risk of humans or livestock getting caught. It is.

When a part of the input port 38 is closed by the shutter 40 as indicated by the dotted line in FIG. As it rotates, the grass, etc. is sequentially sent downward within the casing 20 by the screw 27 of the auger 25, and an open-top container 14 with a packaging or sheet 18 inside is placed directly below the casing 20. Because of this arrangement, the grass and the like that are sent one by one by the screw 27 are stored in packaging or sheets 18 and stacked one on top of the other.

Even after the container 14 is filled with grass, etc.,
Since the auger 25 is rotationally driven, the grass or the like is compression molded, and as described above, when the predetermined compression is completed, the auger 25 can be moved upward by disengaging the clutch 32 or the like.

In this way, the containers 13 and 14 are provided directly below the auger casings 19 and 20, and the augers 24 and 25 in the auger casings 19 and 20 perform feeding and compression packing functions to compress the lawn in the front and back direction. By compressing and packing in the vertical direction, a large compressed product A can be obtained without increasing the length of the body in the longitudinal direction.

After a predetermined amount of compression molding is performed, the opening/closing mechanism 46 is retracted to open the side-view opening/closing door 16 as shown in the third figure, and then the extrusion mechanism 47 is extended to open the extrusion plate 48. The compressed packaged product A is pushed backward through the compressed package A, and halfway through the pushing, it is tilted as shown in the third figure, and then dropped by its own weight.

In addition, if the switching shutter 40 is switched in the direction opposite to the dotted line state in FIG. 2 after compression-molding a predetermined amount of grass, etc. into the container 14, it will be possible to Even if the other container 13 is provided with a lawn, etc., it is possible to compression mold it in the same manner as described above. By providing multiple units, work can be performed continuously without interruption.

The present invention is a device that is attached to a traveling vehicle and compresses and packs grass, straw waste, etc. picked up during traveling, and has a pickup chamber in the lower part and an input port in the upper part of the machine frame having rolling wheels at the front part. A chute is provided, a pickup member that is driven around a horizontal axis to pick up grass, etc. is housed in the pickup chamber, and an auger casing facing the input port is mounted in a vertical position on the machine frame, and the grass is loaded into the auger casing. An auger is provided that compresses and feeds the pasture grass vertically downward, and furthermore, a container with an open top is provided directly below the auger casing on the delivery end side of the auger so that it can be fixed in and out of the machine frame, Since the method is characterized in that the grass and the like are compressed and packed using packaging or sheets inside the container, it has the following advantages.

A chute in which the pick-up member is housed in the pick-up chamber at the bottom is installed at the front of the machine frame with rolling wheels, so grass, etc. that are being picked up and transported through the chute are not scattered, and the auger casing is It is possible to feed the pick-up member reliably and accurately, there is no risk of it being blown away by wind force, etc., and there is no risk of people or animals getting caught in the pick-up member, making it safe.

A container with an open top is installed directly below the auger casing, and the auger inside the casing compresses and packs the grass while feeding it vertically downwards, making it possible to make compressed and packed products that are large in size while still being able to compress and pack the grass etc. in the front and rear directions. There is no need to increase the length of the machine frame, allowing for a compact design.

Since the container of the large compressed package can be moved in and out of the machine frame, subsequent handling is extremely easy.
