4: The invention relates to agricultural machinery and can be used in cotton harvesting machines. The receiving chamber of the cotton harvesting apparatus is known, which has an inlet and a receiving tube connected by means of a knee, which has a grille installed in place of the connected knee with the pickup pipe and located at c. inclined to the window for litter ejection located at the bottom of the cotton receiving pipe L1 3. The disadvantage of this receiving chamber is that it clogs when large impurities come together with the cotton. The purpose of the invention is to prevent the bottom of the receiving chamber. This goal is achieved in that the receiving chamber of the cotton picker, containing the injection and clap receiving pipes connected by means of a knee, has a grating installed at the junction of the knee with the receiving pipe and inclined to the window for waste disposal, located at the bottom of the cotton receiving pipe. It is equipped with a blade jugicV placed in a window for the removal of litter and installed with the possibility of a swiveling movement in the direction of the arrival of the cotton mass in the cotton receptacle. Figure 1 shows the receiving chamber of the cotton harvester, side view; 2 is the same, section A-A in FIG. b is a top view. The receiving chamber of the cotton harvesting apparatus consists of a discharge pipe 1, which is connected to the cotton receiving pipe 2 by means of knee 3, a grating installed at the junction of knee 3 with the cotton receiving pipe 2 and inclined to the window 5. At the bottom of the cotton receiving pipe 2 between the outer the knee 3 wall and the puller 6 are equipped with a paddle roller 7 with the possibility of its rotation in the direction of movement of the cotton mass 8. When the cotton-picker operates, the air supplied by the fan 9, for example, the diameter It comes from the pipe 1 to the cotton receiver of the tubes 2. Cotton collected by the spindle drums of the apparatus is removed from the spindles by the puller 6 and fed to the slot 10 of the receiving pipe 2, where chl oto is picked up by an air flow pumped by a diametric fan 9 and transported through pipes 11 to the bunker 12 of the machine. Heavy impurities under the action of their own weight fall down onto the grate k and roll down to the paddle drum 7. The main weight of the yellow impurities and cotton stalks enter the bottom and immediately fall into the paddle drum 7 Green boxes, branches and heavy impurities fall between the paddle blades When the drum rotates, they are thrown out through the window 5. When debris of cotton stalks hit the drum. throws them out, the long segments of the stems are broken by the action of the blades and thrown out through the window 5. At the same time, the cotton particles are dropped by the blades of the drum 7 and picked up by the ejection air flow. In the proposed receiving chamber cotton-picking machine, the faces are excluded, which will reduce the loss of harvested cotton and increase the productivity of the machine.
