Description

The invention relates to machines for harvesting cuttings using cutting for cuttings, an endless conveyor with clamps and a counter for counting the quantities of processed cuttings. In the proposed machine, an axial knife is used, equipped with a counterweight and periodically set in motion by a twisted spring with the help of a clutch, which is engaged with a knife by a drive dog xles.

The proposed machine is mounted on a wooden bed 1. The front part, carrying the receiving table 4, is located

(514)

horizontally. The continuation of the table obliquely at an angle of 18 °. In front of the table 4, on both sides of it, two drawers 13 are fixed on brackets 15. The table consists of two halves, separated by a slit with inclined edges 16 for the conveyor passage. The inclined part is a bar 2. inclined to the horizon at an angle of 18 °. This bar carries on its upper surface two guide bars 5 of angular equilateral iron, spaced 25 mm from each other, and prednazyach; the first to close the clamps 9 The tip of the inclined beam bears the Bybrashvayuschy bucket with a counter of the usual type. The rear part of the frame on two bearings 20 carries a drive shaft 18 with a flywheel 6, which is driven by the handle 14. The second and third machines can be connected to the end of the shaft 18 by means of an articulated Hook transfer. The conveyor used to receive and move the branches of the geranium is a chain of 3 meshes I and consists of 105 links (Fig. 1, 4 and 5). The hooks of the links 22 are cut so as not to interfere with and not spoil the cuttings. The chain is set in motion by a leading asterisk in twelve teeth, planted on a bulk of 18 mghok. Five receiving clamps 9 are located on the conveyor. The clamp link has four tides 23 on itself (Figs. 4 and 5), on which the clamps 26 of steel 5 or "wire" are fastened. To prevent cuttings from damage, the clamps are trimmed with a rubber band, similar to the pockets of the Brewer planting machine. At a distance of 50mm from the rear clip there is a link carrying a pin-gauge 23, which indicates the end of the upper part of the cutting and serves to push the cutting through the counter. At a distance of 50 mlg from the front clip, there is a link of the cushion 24, (Figs. 4 and 7), on which the cutting rests upon cutting. The cushion, which represents the shaped tide to the link, is also lined with a rubber band. A fixture 8 for cutting the leaves from the cuttings is attached to the guide bars 5 above the conveyor. The device is a tunnel-shaped part 27 (Fig. 12 and 13) with a size in the front part of 45 mm in height, 25 mm in the rear part, with a length of 50 mm. In the front part, the device carries a comb knife 28, 58 with cutting edges 29 (Fig. 12-15). The guide bars 5 at the attachment point of the device have a cutout 30. Above the conveyor 3, a cutting device 7 is attached to the bars m 2 of the bed (Fig. 1) consisting of the following parts: a fixed axle 31 (fig. 16) with cut ends for nuts 32 and with a cam 33 (figs 28 and 27); a ratchet sleeve 34 with a dog 35, a spring 36 and a depression 37 on the rim (Fig. 18-20); a knife washer 38 with a balaxial tide with holes 40 for knife screws and a stop screw 41 (Fig. 29-30) for engaging with the pawl 35; cutting apparatus 7; clamping washer 42 for a knife 43; the driven, rotating on the shaft 31 of the drive wheel 55 with the pawl 44 and the spring 45 entering the recess 37 on the rim of the coupling 34; the drive bevel gear 54, which sits on shaft 47 and is capable of being mounted on it in any position by means of wood-grouse. The shaft 47 is driven into rotation by an asterisk at the other end thereof by means of a chain 17 from the flywheel 18. The ejection bucket

(Fig. 8-11) serves to receive the trimmed cuttings and direct them to the box. The reception ladle consists of two halves -. Each half with: toit from the frame of the 1st double iron alloy 48 reinforced with tapes to the brackets 51 and 52 The brackets, in turn, are attached to the end of the bar 2 using bolts. On the frame 48, planes 50 and 49 are fixed, which serve to guide the cutting coming from the conveyor into box 19. The inclined plane 49 of the rear bucket cell is located slightly below the corresponding plane of the front half, forming a slit into which the cutting is placed. On the brackets 51 and 53, the counter 12 is strengthened.

The work of the machine is as follows. The cut branches of repajJH, no longer than 20-25 hours, carried from the floor, are placed in cases 13. A worker standing in front of the table places separate branches on the clamps of the conveyor with a calculation of falling on the cushion 24 (cutting place of the cutting). The stalk after pruning should have from 12-20 SLS. therefore, when laying the branch in the clamp and on the cushion, this length of the cutting must be taken into account and the cutting point of the Conveyor 3 is set in motion with a linear speed of 0.48 ml1. Speed can be increased. After the passage of the table, the branch is tightly clamped in the clamps due to the latter getting into Epifolvus strip 5. Uv. The branch enters the device 8 with a conveyor belt, where the cuttings of the side leaves are cut by the blades 29 of the comb, of that knife 28.58. The tip remains intact. The branch cleared of leaves is subjected to cutting with a knife 43 cutting. About apparatus 7, the operation of which proceeds as follows. When the shaft 47 rotates from the flywheel 18, the drive bevel gear 54 and the drive wheel 55 located in the clutch rotate with it. When the drive wheel 5S rotates opposite the arrow (viewed against the conveyor belt), the pawl 44 pressed by the spring 45 to the inner surface the rim of the coupling 34, when meeting with the hollow of the rim of the rim 37 enters into engagement and begins to rotate in the same direction

sleeve-sleeve 34. When the latter rotates, the spiral spring 53 attached to it at one end is strong. On the sleeve 34 Echevzhev Shchiba 38 with a counterweight, the knife 43n clamping clamp 42a remains at rest due to the fact that the counterweight holds them in a certain The position to allows the coupling 34 to rotate. When the coupling 34 is rotated counterclockwise, the dog 35 with a weak spring 36 freely passes the stop screw 41 but the chewing washer. The rotation of the parts 55 and 34 continues until the rounded-out shoulder of the pawl 44, the sliding knuckle 31 meets the cam 33. At this moment, the dog jumps out of the cavity 37 and the released coupling 34 under the action of the twisted coil spring S3 begins to rotate backwards quickly hour arrow. With reverse rotation, the pawl 35 catches the stop screw 41 and drives the knife washer 38 with the knife 43, which cuts the cutting and under the weight of the counterweight 39 returns to its original position. The rotation of the shaft 47 with the driving gear 54 continues continuously, and the process repeats periodically. The setting of the cutting moment (adjustment) is achieved very precisely by turning and installing the cam 33 together with the shaft 31. The shaft 31 is fixed in the brackets 57 by nuts (Fig. 21). After passing through the cutting unit, the transporter carries the already prepared cutting further. At the horse conveyor belt (above the drive sprocket), the guide bars 5 K011 are open, and the clips are successively opened by the action of the rubber bands tightened on them. As a result, the cutting enters the discarding bucket 11, the slip on which enters the GE box under the machine.

In view of the fact that a significant amount of working time is spent on the cutting 5.5, a counter 12 is installed on the ejection bucket. The cutting, passing on an inclined plane in front of the bucket, deflects the counter plate, which causes the ratchet wheel to move in each deviation. The counter of an ordinary type of speedomgoa from the system of gear wheels sequentially and alternately with 1 and 10 teeth of L1 and produces counts from i-ro to 9999 cuttings.

The cuttings fall into the box strictly directed (in parallel), thanks to the guiding surfaces 50 and 49 of the bucket.

The subject matter of the invention.
