Description

The invention relates to agricultural machinery, in particular to machines for harvesting seedlings of pumpkin crops, such as cucumbers.

A well-known collection of fruits, containing a separator in the form of an endless ribbon with needles taut on drums, a shaker and a strawberry spreader 1.

However, such a pick-up cannot ensure the reliability of the selection process of seed plants with stalks due to their loading on the tubers, it does not fully select the fruits due to the removal of the testicles with needles by the stalks.

Closest to the present invention is a fruit picker comprising a drum with rings on which needles and a plate puller are fixed, the plates of which are located between the rings of drum 2.

In the known pick-up, the stripper plates are set tangentially to the circumference of the drum, resulting in a decrease in the inclination angle of the needle to the stripper plate in the pickup zone, which leads to pinching of the fetus between the needle and the stripper plate and causing injury to the fruit, which leads to loss of seeds, and also contamination of plates with juice and soil, reducing operational reliability, and contributing to clogging of the pick-up drum in the pick-up area of fruits and stems.

The purpose of the invention is to increase the reliability of the pick-up.

The goal is achieved by the fact that the pick-up is equipped with a beater mounted above the puller, which is made in the fingers in the pickup area of the fingers along an isogonal curve, which in the lower part goes into an arc of a circle whose center is located on the axis of rotation of the beater.

Moreover, the beater blades are equipped with fingers, whose pitch is equal to the pitch of the needles of the drum.

FIG. 1 shows an axonometric pick-up; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The pickup consists of a drum 1 and a puller 2. On the cylindrical surface of the drum rings 3 are fixed, in the holes

pointy needles 4 are inserted. From falling out of the holes of the rings, the needles are held by the heads. In the grooves formed between the rings 3 and the casing of the drum 1, touching its surface, the ends of the stripper 2 plates are arranged along an isogonal curve. The proposed form of plates reduces the area of removal of fruits and stems from needles, which reduces the force on the rotation of the drum. Over puller 2

0 mounted beater 5, the blades 6 of which are made of elastic material and provided with fingers 7, placed with a pitch equal to the pitch of the needles of the drum. When the drum rotates, they enter the gaps between the stripper plates. For the reception and removal of fruits and stems is the conveyor 8.

Picker works as follows.

When the pick-up is moving across the field, the needles 4 of the drum 1 are immersed in the soil to a depth of 2-3 cm. The coupling of the needles 4 to the soil

- leads to the rotation of the drum I and the Impaling of the fruit on the needles 4, which raise them from the ground. Together with the fruit, some of the stems are raised, having a connection with the fruits that are stronger than the linkage of the stems to the roots. Upon further rotation of the drum I, the fruits and the stems enter the installation zone of puller 2, which removes them from the needles 4. Since the stems do not touch the surface of drum 1, they hang on the outer surfaces of the rings 3,

Then the ends of the plates of the elevator 2 are located under the stalks. This prevents pinching and unloading of the stems in the pick-off area of the fruit from the needles. The beater 5 retracts the fruits and stems from the stripper plates 2 to the conveyor 8. The clearances of the stripper 5, which move between the stripper plates, throw the accumulated short segments of the stems into the conveyor belt to clear the gaps between the stripper plates 2 and the stripper plates.

The application of the invention will improve the reliability of the pick-up, which will eliminate the manual labor in harvesting the testes and increase productivity.
