The invention relates to agricultural machinery, in particular to machines for harvesting plants. The purpose of the invention is to reduce seed losses. The machine contains a drum, a 2-gear mechanism. On axis 3, the combs 4 with teeth 5Oxi 3 combs 4 are fixed by means of the crank 6connected to the copying track 7. A fan with a shaft 9, an actuator 10, blades is placed inside the drum. The casing 12 has an entrance window facing the plants and provided with a flap 15, in the lower part limited by a transverse bar. The discharge port is connected to the conduit 18. A brush is provided for cleaning the combs 4. In order to reduce the losses of the seed, the rotor of the fan is located in the housing of the combing body, and the entrance window is equipped with an adjustable valve 1

WITH

The invention relates to agricultural machinery, in particular to machines for cleaning plants by combing heads and inflorescences: rice, herbs, clover and other crops

The purpose of the invention is to reduce the loss of seeds.

FIG. 1 is a schematic side view of a plant combing machine; in fig. 2 - the same plan.

The plant combing machine has a stripping drum 1, which is driven into rotation by the transmission mechanism 2. A comb 4 with teeth 5 (made of metal or of synthetic materials) is hinged on the axis x 3 on the stripping drum. The axes 3 of the combs 4 by means of the cranks 6 are kinematically connected with the copying track 7.

Inside the combing drum 1 is placed a rotor 8 of a fan, for example, diametrically with a shaft 9, an actuator 10 and vanes 11. The casing 12 covers the combing drum outside and has an inlet window 13 facing the combed plants 14. The inlet window 13 is provided in the upper part with adjustable the flap 15. in the lower part is limited by the transverse bar 16. The blower 17 of the fan is connected to the material line 18. The device for cleaning the combs 4 is made in the form of a rotating brush 19.

During operation of the plant combing machine, the stripping drum 1 is rotated by means of a transmission mechanism with an angular velocity cui. Combs 4 of the combing drum are mounted so that the tooth 5 intensively influences the combed mass of plants. This is achieved by cranks 6, which at one end are rigidly fixed on the axis x 3 of the dies 4, and at the other end have

The material combed by the teeth of 5 combs 4 (grain, clover heads, inflorescences of medicinal herbs, etc.) is fed with combs and air flow through the entrance window 13 of the fan (for example, diametrical) into its casing 12 and then through the discharge window 17 - in The material conduit 18 has a material receiver (not shown). The fan rotor 8 (for example, diametrically) has a drive 10, which informs it of rotation with an angular velocity of one to obtain the required air flow rate. The air inlet speed is regulated by a flap 15, which changes the area of the inlet window 13. The cleaning of the teeth 5 of the combs A is performed by a rotating brush 19.

The placement of the fan rotor 8 (for example, diametrical) inside the combing drum 1 and the fan casing 12 is such that it covers the combing
