Abstract

A flax-pulling section with spring-loaded roller contains a frame, a pulley wheel, a guiding roller, a pulling belt, a pressing curvilinear rod and distributors. The support of the guiding roller is made in the form of a frame, the lower part of which serves as an axle of the roller and upper part thereof is rigidly connected by a movable pipe.

Description

Description of the invention

The utility model belongs to the field of agricultural machinery and can be used as a 2nd harvester section.

The well-known TLH-1.5 flax harvesting machine includes a collapsible frame, a picking device with transverse picking rivchaks and a drive mechanism |1). The disadvantage of such machines is the limited copying of the field surface, which is characteristic of mounted types of machines, as well as the unsatisfactory quality of picking stems on loamy soils.

The closest in terms of technological essence to the proposed flax-picking section is the attached flax-picking 70 machine, which consists of attached equipment, a pick-up device with transverse rivchaks, dividers, and two copying devices. The lifting part with the attached equipment is connected to each other with the help of a hinged frame and a hydraulic cylinder. The working bodies are driven by a hydraulic motor (|2). The disadvantage of the mounted flax harvester is that during picking, the stalks are not sufficiently clamped in the zones of the clamping bars of the sections and are incompletely pulled out of the ground, while losses and damage of the stalks occur. 12 The useful model is aimed at improving the linoleum section and ensuring better technical and economic indicators of its work, based on the new structural structure of the section elements.

The task is solved as follows. In the flax-picking section with a tensioned roller, assembly frame, support of the pick-up roller, pick-up pulley, guide roller, fixed pressure curved bars and distributors, according to the proposed useful model, the support of the guide roller is made in the form of a frame, the lower part of which is the axis of the roller, and its upper part rigidly connected to the movable pipe, which is inserted into a fixed pipe of large diameter, which is rigidly connected to the frame of the section and contains inside the guide rod and spring, which provide the roller and the frame with the movable pipe the ability to make a reciprocating movement relative to the frame of the section when change in the thickness of the stem mass, which is clamped in the root canal.

The linen section with a spring-loaded roller is illustrated by drawings: Fig. 17 shows the front view of the (-) linen section and the pulley of the next linen section; Fig. 2 - a view of the section along A-A, and in the drawing C - a diagram of the operation of two sections located next to each other.

The linen section with a spring-loaded roller contains a frame 1; support 2 of the pick-up pulley, pick-up pulley 3, support 4 of the guide roller in the form of a frame, the guide roller 5, the pick-up belt 6, fixed to the pressing curved bar 7, the axis 8 of the guide roller, roller bearings 9, distributor 10, "Her moving pipe 11, roller supports, a fixed tube 12 of a roller support, a guide rod 13 of this support, a spring 14 of the same support and a fixed plate 15 rigidly connected to the support 2 of the pulley. eh

The support 2 of the take-up pulley is rigidly connected to the frame 1; relative to this support, the 3rd pulley can rotate freely

Pulley C is covered from above by belt 6. Support 4 of guide roller 5 is also rigidly connected to the frame. This roller can rotate freely relative to support 4; from below this roller is covered by the same belt 6. This belt is the driving one, it receives the movement from the driving pulley of the machine and transmits it to the pulley C and the roller 5, causing them to rotate.

Stems 16 to be harvested fall into the space between belt 6 and pulley Z, these stems are transported by the belt and simultaneously pulled out of the ground. "

In the area of the roller, in order to avoid the stems from falling out of the pick-up trough, fixed curved rods 7 are installed from the top and bottom of the section. The rods 7 are attached to the supports 2 and plates 15, which are rigidly connected to the support 2. In addition to supporting the stems, they are required to be pressed against moving belt so that they are more reliable

"Iz" were transported in this area, and if the stems remained unpicked, then their picking should also be carried out. For this, in existing machines, the left ends of the rods are spring-loaded. However, such a constructive solution does not give the desired effect, since when passing through the groove of a thick layer of stems, the lower part of the rods is bent, while a space of different widths is formed between the belt and the rods, and where the width is greater, the stems do not press well against the belt. -and It will be much better if the axis of the roller is spring-loaded in the vertical direction, in this case, the pressing of the rod to the waist through the stems will be the same throughout the arc of the waist girth with the rods. Such springing of the roller is proposed in this technical solution. "ride" 20 For this purpose, the axis 8 of the roller becomes part of the frame 4, to which the movable pipe 11 is rigidly connected. The latter enters the stationary pipe 12, rigidly connected to the frame 1. Inside the pipe, there is a guide rod 13 and a spring 14 , which works on compression. Moving the roller up relative to frame 1 compresses the spring, while moving the roller down the spring relaxes. The degree of spring compression can be adjusted. 29 The linobral section works as follows. When the unit is moving across the field, the rods of separators 10 are separated from the stalks of flax and the stalks are brought to the harvesting rivchaks K 4, Ko. Raised stems are clamped with strips of rivchak, moved to the side and thus pulled out of the soil. After that, the plucked stalks are removed from the machine and spread out on the surface of the field.
