Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a loading cart for a container for fruit trees and the like.

(Prior art) When harvesting fruit trees in an orchard, a container containing the dropped fruit trees is placed in the field, and at the final stage of the operation, the container is loaded and collected by the carrier. Taking the method.

However, conventional carriers merely have a carrying function and generally do not have a loading function for picking up containers scattered in a field and loading them on a loading platform.

(Problems to be solved by the invention) Since the conventional carrier truck does not have the loading function as described above, the operator has to artificially load the container onto the bed, and the work efficiency is poor. The loading was very hard work.

The present invention has been made in view of such conventional problems, and an object thereof is to automatically pick up an object to be loaded such as a container scattered in a field and load it on a loading platform.

(Means for Solving the Problem) In the present invention, a pair of left and right transmission cases 17 are provided on the front portion of a trolley 1 having a traveling device 2 and a loading platform 3 in a front-spreading manner and in a front-lowering manner. The case 17 is provided with a lower cone and an upper drum, which rotate inward so as to receive an object 12 to be loaded such as a fruit tree container and convey it to the cargo bed 3 side, through which the trolley 1 advances. At the same time, a push rod 32 for pushing the upper side of the article to be loaded 12 and lifting the end portion on the conical disc is provided from one of the transmission cases 17 so as to project inward from the front.

(Operation) When the trolley 1 is moved forward so that the load 12 is located between the pair of left and right rotating body rows 13, the push rod 32 pushes the upper side of the load 12, so that the load 12 The end part is lifted and rides on the rotating body row 13. Then, when the load 12 is further advanced, the load 12 rides on the pair of left and right rotating body rows 13. Therefore, the load 12 is conveyed backward by the rotating force of the rotating body row 13 and loaded on the carriage 3. Go in. Therefore, it is possible to pick up the loaded objects 12 scattered in the field and automatically load them.

12 is a container for fruit trees, 13 is a row of rotating bodies for loading the containers 12 scattered in the field on the loading platform 3, a pair of left and right are provided at the front part of the loading platform 3, and the row of rotating bodies 13 is spread forward and It is arranged in a downward direction. Each rotator row 13 is composed of a front rotator 14, an intermediate rotator 15, and a rear rotator 16,
Each of the rotating bodies 14 to 16 is rotatably supported via a vertical axis 18 to 20 on a transmission case 17 of which the rear end is fixed to the trolley 1 and which is in the form of a forward spread and a downward slope. The containers 12 are driven inwardly so as to be transported to the cargo bed 3 side via the chain transmission mechanism or the like. The front rotating body 14 and the middle rotating body 15 are conical discs 21 and 22 arranged below the transmission case 17.
And the drums 23, 24 arranged on the upper side of the transmission case 17, and the rear rotating body 16 is composed of the drum 25 arranged on the upper side of the transmission case 17. The pair of left and right conical discs 21 and 22 can receive the container 12 from the lower side and can be transferred to the rear by the rotational force of the conical discs 21 and 22.
2, the front side has a larger diameter than the rear side. Drum 2
3 to 25 have rubber-like protrusions 26 to 28 on their outer circumference in the axial direction.
Are provided to guide and transfer the container 12 rearward. A guide plate 29 is provided on the rear side from the space between the intermediate rotating bodies 15 so as to receive and guide the container 12 from below so that the container 12 does not drop downward.

A support rod 30 is provided at a front end portion of each transmission case 17 so as to project forward, and a caster wheel 31 is provided at a front end of the support rod 30.
Is installed. 32 is a container 12 when the trolley 1 is moving forward
Push the upper part of the end of the conical disc of the front rotor 14 of the rotor row 13
21 A pair of left and right transmission cases with push rods for lifting
Of the 17, a transmission case 17 on the side of the control device 6 is attached to the front end of the transmission case 17 so as to be inclined forward and obliquely. This push rod
32 is a rubber-like projection for preventing slippage at the tip as shown in FIG.
A tubular body 34 having 33 is slidably fitted on the guide rod 35, and a buffer spring 36 for urging the tubular body 34 forward is provided therein.
And the guide rod 35 is attached to the transmission case 17 via the bracket 37. Reference numeral 38 denotes a protective cover, which is installed between the carriage 1 and the support rod 30 so as to cover the outer half of each rotating body row 13 from the outer side to the upper side.

When the containers 12 scattered in the field are picked up and loaded by the loading cart having the above configuration, the following steps are performed. That is, when the trolley 1 is advanced so that the container 12 is positioned between the pair of left and right rotating body rows 13, the push rod 32 abuts on one end side upper part of the container 12, and the one end side upper part of the container 12 is moved to the first side. Since the container 12 is pushed in the direction indicated by the arrow a in FIG. 1, the container 12 is rotated in the direction indicated by the arrow b by its pressing force, and the other end is lifted from the field as shown in FIG.
Then, when the carriage 1 further advances, the other end of the container 12 is lifted above the outer peripheral edge of the conical disc 21 of the front rotating body 14, so that the conical disc 21 enters the lower side of the container 12. At this time, the container 12 rotates about 90 degrees, the push rod 32 comes off the container 12, and the container 12 is oriented substantially in the front-rear direction, so that it receives the rotational force of the conical discs 21 of the pair of left and right rotating body rows 13, It is forcibly transferred backward (indicated by arrow c) by the rotational force. Then, it is sequentially transferred from the conical disc 21 of the front rotary body 14 to the conical disc 22 of the intermediate rotary body 15, and is loaded onto the loading platform 3 by the pair of left and right drums 25 of the rear rotary body 16. Even if the container 12 moves to the left or right a little during the loading, the pair of left and right rotating body rows 13 are spread forward, and the distance between the left and right becomes smaller as it goes backward,
The container 12 moves rearward while being sequentially returned to the front-back direction posture by the drums 23 to 25. Therefore, by simply moving the cart 1 forward, the containers 12 scattered in the field can be automatically picked up and loaded on the loading platform 3. Further, since the left and right rotating body rows 13 are spread forward, they can be loaded regardless of the orientation of the container 12. Container on the loading platform 3
12 should be rearranged appropriately by the worker.

The traveling device 12 may be a crawler type. Further, the guide plate 29 may be replaced with a roller table having a large number of idle rollers, or may be replaced with a drive type conveyor.

Furthermore, although the container 12 is illustrated as an example in the embodiment, the present invention is not limited to this, and the present invention can be applied to the loading of a haval.

Further, the rear end of the transmission case 17 may be pivotally attached to the carriage 1 so as to be vertically movable around the horizontal axis so that the caster wheels 31 follow ups and downs of the field.
