and the collecting cloth is arranged on the upper surface of the supporting mechanism.

Furthermore, one or two support rods positioned in the middle of the support mechanism are fixedly connected with the mounting frame.

Furthermore, a part of the support rods positioned in the middle of the support mechanism is connected with the mounting frame in a sliding manner.

Furthermore, three groups of connecting rods are arranged between two adjacent supporting rods, and the rod lengths of the three groups of connecting rods are different.

Furthermore, a first long groove, a second long groove and a third long groove which are arranged in sequence and are mutually independent are arranged on the support rod, and the three groups of connecting rods respectively correspond to the first to third long grooves in sequence.

Furthermore, the collecting cloth is fixedly connected with the upper surface of the supporting rod, and the collecting cloth is in a circular ring structure after being unfolded.

Furthermore, the locking piece is a bolt, and two support rods at the tail end of the support mechanism are provided with corresponding round holes.

The invention has the beneficial effects that: the folding type kernel fruit harvester spreading arm is convenient to use, when in use, only two support rods at the tail end need to be pulled outwards, then the two support rods at the tail end of the support mechanism are locked together, and at the moment, the whole support mechanism is encircled into a ring shape and surrounds a fruit tree trunk. Like this, the stone fruit that drops from fruit tree crown alright fall on collecting the cloth, be convenient for collect.

Detailed Description

As shown in fig. 1 to 7, the present invention mainly comprises a mounting frame 1, a supporting mechanism and a collecting cloth 4, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the mounting frame 1 is a profile welding part, and the mounting frame is used for being fixedly connected with a frame of the shaking type harvester. The mounting frame is provided with a supporting mechanism, as shown in fig. 2, the supporting mechanism comprises a plurality of supporting rods 2 arranged from left to right in sequence and a connecting rod 3 arranged between two adjacent supporting rods, the supporting rods are metal straight rods, as shown in fig. 3, a first long groove 21, a second long groove 22 and a third long groove 23 are arranged in the supporting rods in sequence, and the first long groove, the second long groove and the third long groove are mutually independent. Three groups of connecting rods 3 are arranged between two adjacent supporting rods, the two connecting rods in each group are hinged and connected in a V shape, the first ends of the two connecting rods are hinged and connected through a hinge shaft, the second ends of the connecting rods are arranged in the long grooves (the first long groove, the second long groove or the third long groove) of the corresponding supporting rods, and the connecting rods are hinged and connected with the supporting rods. Two adjacent support bars and three groups of connecting rods between the two support bars form a folding unit, and as shown in fig. 4, when the two support bars are extruded towards the middle, the two connecting rods can be driven to be close to each other, so that the included angle between the two connecting rods is reduced. As shown in fig. 5, until the two support rods contact each other, the two connecting rods arranged in a group are placed in the space formed by the two first long grooves (or the second long grooves, or the third long grooves). Thus, the entire support mechanism is made up of several adjacent folding units. The support rods on the leftmost side and the rightmost side are provided with round holes 24, as shown in fig. 6, the mounting rack is fixedly connected with one or two support rods arranged in the middle position, the two support rods on the left side and the right side of the support rod in the middle position are always in sliding connection with the mounting rack, and the sliding direction is a circular arc direction. When the two support rods of the folding unit are driven to move away from each other, as shown in fig. 6, the whole support mechanism gradually changes from a straight shape to a fan shape, as shown in fig. 2, and then gradually changes from the fan shape to a circular shape. The round holes on the two support rods at the two tail ends are aligned, and then the bolt 6 is inserted into the round holes, so that the shape of the whole support mechanism is fixed. At this moment, a plurality of bracing pieces evenly set up on same circumference, and bracing piece self along the radial setting of this circumference, and this supporting mechanism's inboard forms the cavity that encircles the fruit tree, and the external diameter of this cavity is greater than the fruit tree trunk external diameter. The bolt forms a locking member for locking together two support rods at the end of the support mechanism.

The upper surface of the supporting mechanism is provided with a collecting cloth 4 which is in a ring shape after being unfolded. The collecting cloth is fixedly connected with the upper surfaces of the supporting rods, so that the collecting cloth between the two supporting rods can be folded. After the whole supporting mechanism is unfolded, the collecting cloth is also unfolded, and the surface is flat.

As shown in fig. 7, in use, the shaking harvester is first moved to make the trunk of the fruit tree 5 close to the supporting mechanism, and then the supporting mechanism is unfolded to make the supporting mechanism surround a circle, at this time, the fruit tree trunk is placed inside the supporting mechanism, and the fruit tree crown 51 is placed above the collecting cloth. When the fruit tree trunk shakes, the stone fruit on the crown falls on the collecting cloth, then rolls along the collecting cloth, and most of the stone fruit falls through the gap between the trunk and the supporting mechanism.
