Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a harvesting machine for high-altitude crops such as oil palm and coconut.

Traditionally, in order to harvest the above-mentioned high-altitude crops, workers used a long-handled cutting tool to cut off the crops from above the ground and collect the crops that fell to the ground. There was a problem that the work efficiency was extremely low when harvesting a large number of palm trees. In addition, there is also the problem that falling crops may hit workers or be damaged due to collisions with the ground.

An object of the present invention is to provide a harvesting machine that can harvest high-altitude crops without the above-mentioned troubles and has excellent versatility.

The characteristic configuration of the harvesting machine according to the present invention is that a self-propelled vehicle equipped with a driving section and a loading platform is provided with a work platform for handling the harvested products at a high place, and a chute for receiving the harvested materials to be leveled and guiding them to the loading platform side. The working device is detachably connected with the working platform positioned above the self-propelled vehicle.

In other words, by providing a workbench, it is easier to cut off crops with a long cutter, etc., compared to cutting off high-altitude crops directly from the ground. can be directly guided and accumulated on the loading platform,
Compared to the conventional method of picking up and collecting crops that have fallen on the ground, collection efficiency can be improved.Furthermore, by placing the workbench above the self-propelled vehicle, it is possible to collect crops that have fallen on the ground. Compared to arranging the harvester on the side, the length and width of the entire harvester can be made smaller, making it easier to turn around and traveling more effectively, making the overall work extremely efficient.

Furthermore, since the falling harvest is caught by the chute, the safety for workers is greatly improved, and the harvest can now be collected in a good quality condition without damage.

Furthermore, since the working equipment can be removed from the self-propelled vehicle, the self-propelled vehicle can also be used for purposes other than harvesting, such as transporting harvested products from one (company) field to a processing plant, or transporting fertilizer to a field. I was able to do that.

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

As shown in Figures 1 and 2, a crawler traveling device (1
), and the front part of the self-propelled vehicle, which has a driving part (2) and a driving part (3) arranged in parallel on the left and right at the rear, is equipped with a loading platform (4) around the axis on the front end side using a hydraulic sill (5). It can be installed to allow for vertical swing operation to form a transport vehicle capable of dumping the cargo platform.
Then, the workbench (9), which has a support frame +71K which is equipped with a protector (6) for the driving part (3) and a side frame (8) erected around the entire circumference, is installed using a hydraulic sill (
The lift mechanism (11) that can be bent and stretched by the

) or (13b) to enable rocking operation around the axis (Pl) on the lower end side, and a ladder 04) for getting on and off the workbench (9) is provided at the rear of the support frame (7). A work device consisting of a work platform (9) is located above the self-propelled vehicle, and both nets θ2) l t+4+ are a loading platform (4
) are connected to the transport vehicle in a state where they are located separately on both the left and right sides of the tree, thereby forming a harvesting machine for harvesting oil palm fruits (a) as shown in FIG. 3.

That is, the net (12a) or I/'1 (12b) is made to protrude to the outside of the mechanism, and the arm (16) K, which is extended from the free end side of the net frame (16), is tilted toward the tree. The worker uses a long-handled cutting tool θ to cut off the fruit (a) on the working table (9), and the fruit (a) falls down.

The pin □□□ is fixedly fixed to the 7th frame frame of the vehicle body through the guide part (G) for vertical movement, and the range of swing of the working device around the two axes (P2) and (P3) is regulated. Within the regulated range, the workbench (9) is maintained parallel or almost parallel to the ground, regardless of the back-and-forth rocking and left-right rocking of the transport vehicle.

Switch t2s for operating the cylinder (to) and (13a) T (13b)! (29a)+(29,
b) is installed on the workbench (9), and the electromagnetic operation part of the control pulp (not shown) installed in the transport vehicle is equipped with megilinda (to) I (13a) - (13b).
An electric circuit configured so that only one operation is possible (
(not shown), and the operation unit (not shown) is connected to the drive unit (
3) and the workbench (9).When operating from the workbench (9), for safety, the workbench (9) and the left and right nets (12a) + (12b) must be connected. This prevents simultaneous operations.

As shown in Figure 2, the left and right net frames (15) +(+
5) can be rocked by a base end portion (15a) which is pivoted to the support frame (7), and a pivot shaft (30) in the longitudinal direction of the body on this base end portion (15a). The distal end portion (15b) is connected to the proximal end portion (15a) and the distal end portion (15a) is divided into two parts so that the waist can be bent and stretched. The net (12a) ν (12b) and the net frame θ0 are fixed in the extended and used state when the net (12a) ν (12b) and the net frame θ0 are fixed in the extended use state, and the net (12a) is moved in a non-working state like on the road. When doing so, remove the locking device (31) from either one of the net frame portions (15a) + (15b) and remove the net (12a) so that the height of the machine is lower than when working. + (12b) and net frame (
15) can be stored in a folded state in which the distal end portion is folded in two along the proximal end portion.

Both net frames (+5) l (+5) each have the 8th
As shown in the figure, the proximal part (15a) and the distal part (15a)
5b) is provided with a reinforcing frame which is constructed and connected across the pair of left and right pivot parts. That is, the free ends of the front and rear pair of 7 frames constituting the proximal end portion (15a) and the proximal ends of the front and rear pair of frames constituting the distal end portion (15b) are repaired. The strength of the net frame (16) is improved by connecting the net frames (16) with each other. And the said reinforced 7 frames □□
□ is formed into a curved shape on the back side of the net (12), and is suspended from a pair of left and right pivot shafts (30). In this case, the reinforcing frame is stored along the net frame (16) due to its own weight so that the amount of outward protrusion of the frame is small, and the net (12a) and (12b)
) is used in an inclined state, the net (12a) + (
Even if the fruit (a) is bent downward due to the weight of the fruit (a) received by the net (12b), the net (12a) is used to prevent the fruit (a) from colliding with or getting caught by the reinforcing frame 7! (12b) The reinforcing frame support is configured to automatically switch by its own weight to a posture toward the net in which a gap exists between the reinforcing frame and the net.

As shown in FIGS. 1 and 7, a pair of left and right front and rear frames (34a) + (34b) forming the support frame (7)

23a) 1 (23b) and the stand (23b)) (Construction 17) allows the working device to be supported on the ground in a connected position with respect to the transport vehicle or in a position almost thereto by cooperation with the stand. When attaching and detaching the work equipment, simply move the front end horizontal frame (+8) back and forth to remove the bracket (21) and both front and rear 7 frames (34a).
) ν (34b), so that the working device can be supported in a position on the ground that provides a positioning state in which attachment and detachment of the three components can be performed at once, and the working device can be easily attached and detached.

(12a) + (12b) can be changed to a gutter-like body or the like, and these are collectively referred to as chute (12a) + (12b).

Note that the work platform (9) may be constructed in a stationary manner instead of being able to be raised and lowered, and the loading platform (4) may also be configured as a stationary loading platform instead of a Gump loading platform. Configuration changes are possible.

The harvesting machine according to the present invention is capable of harvesting various crops that grow in high places, such as oil palm and coconuts.
