Description

The invention relates to the field of agricultural engineering and can be used in machines for selective harvesting of melons and gourds.

The purpose of the invention is to provide selective harvesting of fruits.

Figure 1 shows a general view of a machine for harvesting fruits of melons and gourds; figure 2 is the same, top view; FIG. 3 shows a working body for the selection and movement of fruits; FIG. 4 is a section A-A in FIG. 3; figure 5 - schematic representation of the various stages of the selection of the fetus working body; in fig. 6 — node I in FIG. 3 (enlarged); in fig. 7 - receiving conveyor; on Fig the same, top view; figure 9 - section bb in figure 7: figure 10 - section bb In figure 7.

The machine consists of a drive 1, on the frame 2 of which the support bars 3, 4, 5 and the drive shaft 6 connected to the gearbox 7 are mounted. The working body is made of two cylindrical spirals 8, the adjacent ends of which are rigidly connected to the drive shaft 6, and opposite ends are connected to the shaft b by means of movable clamps 9. A receiving conveyor 10 is located under the working body, consisting of a frame 11, a tension 12 and a drive 13 pulleys, swivel rollers 14 and a load bearing body 15 with cells 16, the bottom of which is formed perforated elastic elements cients of the receiving conveyor 17. The actuator 10 is accomplished by the sprocket 18 associated with chain 19

drive sprocket 20 mounted on the drive shaft b. The receiving part of the conveyor 10 is located in the technological slot 21 and rests on the support wheel 22. A drive 23 is attached to the rear of the machine.

The machine works as follows.

Through frame 2, the working body is set at a predetermined distance from the ground so that helix 8 does not pinch the lash. Moving the latch 9 on the shaft 6, adjust the required pitch of the turns of the spiral 8 depending on the minimum size of the harvested fruit.

When moving along the technological gap 21 from the power take-off shaft, the engine, through the gearbox 7, rotates the drive shaft 6 and the spirals 8 associated with it. When the turns of the spiral 8 meet with the fruits previously separated from the rods, the fruits are oriented in the inter-turn space. In doing so, the fruit, overcoming the elasticity of the coils, pushes them apart and pinches. With further rotation of the working body, the fruit is torn off from the surface of the earth, and then, under the action of its own weight, rolls into the internal cavity of the helix 8 and rolls in turns to the receiving conveyor 10. spring bottom 17 and the fetus is securely fixed and protected from damage. The receiving conveyor 10. delivers the fruit in the drive 23.

The smaller fruits, not separated from the lashes, pass without being caught between the turns and remain on the field for re-collection.

Making the linear speed of rotation of the spiral 8 and the translational speed of the machine equal contributes to the preservation of the fruit when they are pinched by the turns of the working member.
