SU120973A1 - Cotton harvester with clamps for collecting raw cotton and closed boxes - Google Patents

Description

The used machines for collecting raw cotton and unopened boxes have significant drawbacks: they poorly copy the soil relief, are very sensitive to the moisture of raw cotton and do not have sufficient versatility.

The proposed apparatus is characterized in that in its front part there are drums with hooks for picking raw cotton, and in the rear part drums with hooks for picking up closed boxes. This achieves the possibility of simultaneously collecting raw cotton and closed boxes in separate bins.

FIG. 1 shows a schematic side view of a drum for collecting raw cotton; in fig. 2 is a plan view; in fig. 3 - drum for collecting boxes, side view; in fig. 4 - view in plan; in fig. 5 - capture boxes.

Drums for collecting raw cotton and drums for collecting closed boxes include common parts; the shafts 1, the hubs 2 with rims between which the working bodies are mounted, as well as two guide tracks on each drum — lifting 3 and clamping 4. The tracks serve as drives for moving the stem in the axial direction.

The working bodies of the cotton picking drum consist of tubes 5 placed along the drum core, rubber clamps 6, locking rings 7, locking bolts 8, brushes 9, schtang // and shtang 10. The rods are designed to raise and lower the rubber clamps installed on them . Between the clamps put rings with locking bolts that regulate the position of the clamps on the shtange. This ensures uniform pressure on the rubber-reinforced windows, which form grippers.

A tube with windows located along the generatrix serves to hold the cotton fiber pressed by the rubber clips. Brushes are installed for dumping cotton into the bunker.

The same design has drums for collecting closed boxes. The working bodies of these drums consist of rods // on which metal clips 12 are placed with a bias towards the axis of drum No. 120973-2 -

on, the grippers 13 fixed on the formation, it has 14 drums, strips 15 of the stop, separating knife 16 and comb 17.

The proposed machines for the collection of raw cotton and bolls can be installed on the existing CXM-48 and CXM-48M cotton harvesting machines.

To collect raw cotton and bolls at the same time, the devices should be installed in the following sequence: in front of the mashhips are drums with grips for raw cotton, and behind them are drums for collecting bolls.

When installing drums to collect raw cotton, they are arranged in pairs in an upright position. The drums for collecting the closed boxes (kurak) are installed with such an adjustment that against the slit of one drum there is a gripping of the other drum. When collecting the half-open boxes, the second drum is replaced by the pressure drum, and the first drum is covered with a separator grid. The clamping drum instead of the working bodies on the entire cylindrical surface has flat plate rubber. In this case, the drums are arranged in a shakhmatny order on both sides of the bush.

When moving maschiny cotton bushes pass between the drums. In the front drums, the fibers of the opening boxes of raw cotton are pressed into the windows of the tube. At this moment, the presser arc presses on the shaft and moves it to the lowest position, and the rubber clips move along with the shaft. The cotton fibers pressed in the windows are separated from the bolls and, together with the rotating drums, are fed to the brush, from where they are thrown into the bunker.

The remaining kurak on the bushes is compressed in the rear drums between the grip and the clamp to a certain size, limited by the height of the stop bars, and empty boxes, branches and other impurities slip out of the cracks due to the insignificant volume. The compressed hen is moved by the drum to the knife, which cuts the hen off from the cotton branches. Upon further rotation of the shtanga drum, the pusher, together with the clamp, rises, releasing the kurak, which is ejected by the centrifugal force by the comb into the collection chamber and further into the bunker.

When collecting the wire cutter, the grid separator closes the drum slots, blocking the path to the kurak. The slug penetrates between the mesh B of the slot and its hall with clamps with its flaps. When assembling the piece, the knives must be moved from the drum to a distance that ensures the piece from damage.

A cotton harvest prototype has been prepared and is being tested.

Claims (6)

1. A cotton harvester with clamps for collecting raw cotton and closed boxes, characterized in that, in order to simultaneously collect raw cotton and closed boxes in separate bins, in the front part of it are installed drums with clamps for collecting raw cotton, and rear - drums with grippers for collecting closed boxes. 2. A cotton harvester according to claim 1, characterized in that, in order to collect raw cotton and closed boxes, counter-rotating drums on vertical axes are used in it, along the generators of which clamps are placed with a frequency that prevents the cotton boxes and cloves from passing - shit 3. A cotton harvester according to Claim 1, characterized in that, in order to grip and clamp raw cotton and bolls between working surfaces, the supporting surfaces of the grippers are installed in the windows of the tubes placed along the generator of the drum, and the pressing surfaces the grippers are assembled on the rods placed in the pipes and connected to the supporting surfaces from below. 4. Cotton harvester on PP. 1, 2, and 3, characterized in that, in order to clamp the raw cotton and the bolls between the working surfaces of the grippers at the time of their stay near the bolls and to release the clamps from the raw cotton at the moment when the clamps move away from the bolls, direction driven by the guide track, which is mounted on the upper end of the drum. 5.Chl) cleaning machine according to claims. 1, 2, Zi4, characterized in that the supporting and pressing surfaces of the grips of the front drums for picking raw cotton are reinforced with rubber, and for the rear drums for collecting the closed boxes, the bearing and pressure surfaces of the grips are metal and have a slope towards the axis of the drum. 6. A cotton harvester according to claim 1, characterized in that, in order to better insert the closed boxes into the jaws, a pressure drum with rubber sleeves located along the drum generator is installed against the gripping drum. / W-: - - Ch-G - Y .., ATT 1 pi T -} V (: 4j: S- / 1 Al7; Well  GK  S%    A
