2. Description of the Related Art In a golf course, in order to manage a wide lawn with good quality, maintenance work such as mowing a lawn with a lawnmower and adjusting the height of the lawn is performed regularly. Leaving thatch as it is after mowing may hinder turf growth,
In addition, since the competition will be hindered, the course will be cleaned and collected by thatch collection vehicle. Conventionally, the collected thatch is piled up at various places in the course and then collected later, but this collection work requires a great deal of labor and time. In order to solve this problem, the present applicant has proposed, in Japanese Patent Application Nos. 7-242555 and 7-2487771, a hatch collecting machine and a hatch bagging apparatus for automatically performing thatch collecting and bagging. did. In these applications, the means for collecting the cut turf thatch and the means for bagging the collected thatch were able to achieve a reasonable effect. However, when replacing a full thatch storage bag with a new empty bag, it is necessary to interrupt the bagging operation, which results in a loss of work time, and therefore, an improvement in efficiency has been demanded.

[0003]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, in the present invention, the cut thatch is continuously packed in a bag, and the operation of collecting thatch is continued without interruption, resulting in an efficient operation. It is an object of the present invention to provide a sack bagging device.

[0004]

In order to achieve the above object, according to the present invention, a bag stuffing section is provided on the left and right side of the above-mentioned collecting truck.
The end portion of the transfer duct is branched right and left to form a pair of left and right discharge tubes integrated with the transfer duct, and a switching shutter is installed at the branch portion, and the discharge ports of each discharge tube are connected to the left and right bag filling portions. Looking into the bag mouth of the suspended thatch storage bag, the rotatable transfer duct is attached rotatably, and the transfer duct is rotated forward or reverse to set one of the outlets of the pair of left and right discharge cylinders to the outlet. The switching shutter is switched to the lowered discharge cylinder side while descending toward the bag mouth of the Thatch storage bag.

Reference numeral 6 denotes a support piece 37 made of a plate material such as a hard board and protruding outward from one side of the upper opening, and a pair of support holes 38 through which the bag support rod 18 is inserted are formed in the support piece 37. A large number of the support holes 38 of the storage bag 36 are inserted through the bag support rod 18 to support a large number of them.
6 is supported so that it does not fall off. In this state, the bag opening of the Thatch bag 36 is opened by hooking the bag opening claw 26 to the bag opening of the Thatch bag 36 and shifting the bag opening claw 26 backward.

Next, the operation of the bag filling apparatus of the present invention will be described. First, a large number of thatch storage bags 36 are inserted through the support holes 38 and supported by the bag support rods 18 of the left and right bag mounting sections 16, and the support pieces 37 are pressed by the bag holding springs 21. When power is supplied to the bag filling device, the bag opening unit 17 on the right side in the traveling direction is activated as an initial state, and the first moving frame 22 and the second moving frame 23 advance to the bag mounting unit 16 side, and the first moving frame 22 Storage bag 3 by the bag mouth holding plate 24 at the tip of
6, the opening tab 26 of the second moving frame 23 is depressed by the opening electromagnetic cylinder 25 and hooked on the bag opening of the storage bag 36. Open the bag mouth of 36. Simultaneously, the duct switching electromagnetic cylinder 33 is operated, the operating rod 32 is pulled, the support 31 is tilted around the duct rotating shaft 30, the terminal end portion 7 of the transport duct is inclined, and the discharge cylinder 8 a is moved to the Thatch bag 36.
Into the bag opening. At this time, the switching shutter 34 of the terminal portion 7 is also operated to open the discharge tube 8a and close the discharge tube 8b. Driving the Thatch collection vehicle 2 by driving the Thatch collection vehicle 1,
The collected thatch is pneumatically conveyed to the terminal end portion 7 by the conveying fan device 3 through the conveying duct 4 and packed in the Thatch bag 36. On the other hand, the bag mounting section 16 on the left side in the traveling direction prepares for the above-described initial state and waits.

If the weight of the bag 36 is larger than a predetermined weight, the weighing rod 27 located below the bag 36 is pushed down, and the weight sensor 29 detects this. As a result, the duct switching electromagnetic cylinder 33 performs a reversing operation, raises the discharge tube 8a, lowers the discharge tube 8b at the same time, and inserts the tip of the discharge tube 8b into the Thatch storage bag 36 set to the initial state on the left side in the traveling direction. At the same time, the switching shutter 34 is switched, and the stitch is packed from the discharge cylinder 8b into the thatch storage bag 36. Then, in the bag mounting section 16 on the right side in the traveling direction, the Thatch bag pushing mechanism 20 pushes out the Thatch bag push-out plate 19 backward, pushes out the Thatch bag 36 filled with the Thatch, and releases the locking of the bag holding spring 21. , And is discharged from the tip of the bag supporting rod 18. At the same time, the first
The moving frame 22 is also turned over to return the bag mouth holding plate 24 to support the sock storage bag 36 packed with that so as not to drop suddenly. Thatch storage bag 3 packed with thatch
When 6 is discharged, the bag mounting section 16 on the right side in the traveling direction is set to the initial state and waits. Thereafter, by sequentially operating the left or right thatch bag stuffing device sequentially, the sack bagging is continuously performed.

When the collected thatch is moist, the bag may be caught in the bag when the bag is packed, or the bulk of the hatch may increase and overflow the bag opening before the set weight. At this time, the pressure sensor 35 provided on the upper surface of the terminal end portion 7 detects an increase in the air pressure in the duct, and when the increase in the air pressure exceeds a predetermined value, confirms that the storage bag 36 is full and the duct switching electromagnetic cylinder By driving 33 and inverting the end portion 7 to switch to the other bagging device, it is possible to prevent overflow from thatch storage bag 36. As described above, in this embodiment, even if the Thatch storage bag becomes full, the bag filling operation can be continued without stopping.

[0011]

As described above, according to the present invention, bagging portions are provided on the left and right sides of the rear portion of the thatch collection vehicle, and the discharge duct is formed at each of the left and right ends by branching the terminal end of the transport duct to the left and right. Looking into the bag mouth of the Thatch storage bag suspended in the bag filling part, rotating the terminal end of the transfer duct to the left and right, alternately inserting the discharge tube into the bag mouth, and switching the shutter together, When one of the bags is full, the other bag can be switched to the other bag and the bag can be packed continuously. Therefore, it is possible to efficiently perform the process of packing the bags in a continuous manner.
