SU515502A1 - Electric Sterilizer for Fallen Plant Parts - Google Patents

Description

The invention relates to agriculture, in particular to the technique of combating cotton wilt.

Devices for treating plants in rows using an electric current are known, which contain a current source and an electrode system: grounding, made in the form of a plow, buried in the soil, and sliding, made in the form of plates. The principle of operation of the known device is based on the fact that the current flowing between the electrodes strongly heats or burns the plants that are in contact with the sliding electrode.

However, when using such a device to sterilize fallen plant parts, it is necessary to position the sliding electrode close to the soil surface, on which the sterilized material is randomly scattered. In this case, due to unevenness of the relief between the spaces, frequent contact of the sliding electrode with the ground is inevitable, resulting in short circuits between the electrodes, which violate the overall mode of operation of the electricizer.

The purpose of the invention is to improve the processing efficiency of fallen plant parts.

For this, the electrode system of the electrosterilizer includes successively arranged electrodes, the first of which are made of fan-shaped consumable metal elements, and the second are in the form of spring-loaded combs.

FIG. 1 shows the proposed electric sterilizer, side view; in fig. 2 - sliding electrode, front view; in fig. 3 - grounding electrode, front view.

The electro-sterilizer for opeds of plants is a frame 1 on which sliding 2 and ground 3 electrodes are mounted. The frame is mounted on wheels and clings to the tractor.

The source of electricity is a generator driven by a shaft of selection.

tractor power. A step-up transformer 4 with control panel 5 is connected to the generator. Sliding and grounding electrodes are connected to the terminals of the transformer.

Sliding and grounding electrodes are installed in the working or transport position by means of an electric drive with a screw gear 6. In the working position, the electrodes are adjusted in height with additional nuts 7. To avoid breakage of the electrodes when springs hit the combs and other items, springs 8 are provided. The sliding electrode consists of metal rods 9, mounted on an insulating base 10, and a bracket 11, with the help of which the electrode is attached to the hinge lever.

The grounding electrode is made in the form of steel dies 12 in the form of a knife, attached to bar 13 at some distance from one another. The strips are of different lengths and are attached to the timber in such an order that they roughly replicate the transverse profile between the rows. The beam 13 is fixed on the insulating base 14, which is zash, ish, en partitioned from the flame by the partition 15.

The grounding and sliding electrodes are hinged to the frame 1 by means of the lever 16.

In order to collect leaves that have fallen not only in the furrow, but also on the ridge row, the width of the grounding electrode can be made equal to or slightly larger than the width between the rows. Moreover, the edges 17 of the electrode are connected with the middle part of the hinge, for which they are provided with an axis 18 and a return spring 19.

The device works as follows.

Before entering the cotton rows, the sliding 2 and grounding 3 electrodes are lowered into the working position. In this case, the grounding electrodes of the same series are installed at different heights, for example, the comb of the first electrode touches the ground, the second one is slightly pressed against it, the third one is pressed more strongly. While moving along the rows, the part of the pile passed by the first electrodes will be collected next, which contributes to the uniform distribution of the pile between each pair of electrodes. This prevents the heap overflow of the first two pairs of electrodes.

As the device moves along the rows of plants of the comb 12, the grounding electrodes, acting like a rake, collect

in a pile of fallen parts of plants. Small lumps of soil are sifted out between the teeth of the comb. When the fallen parts of the plants accumulate so much that this pile touches the sliding electrode, which is under voltage, the arc is applied to the hall.

Combustion may cease if there is not enough sterilizing material between the opposite electrodes. However, as soon as the accumulated pile overlaps the interelectrode space, combustion will resume.

When the device moves, the edge 17 of the grounding device collides with the stalks. At the same time, in order to avoid breakages, these edges are folded back, turning around axis 18, and after release from the stem they jerk back to their original position by the action of spring 19. As a result, the leaves of the ridge are dropped into the furrow, where conditions for complete sterilization are better.

Safety of staff is provided by well-known safety measures for mobile electrical installations.
