Description

The utility model relates to agricultural engineering and can be used for the mechanization of work in horticulture, in particular for the destruction of weeds in the near-trunk strip of the garden.

Known device for introducing solutions of herbicides in the near-trunk strip of the garden [1], containing a supporting bar and a swivel bar with sprayers. In operation, the swing arm is in the row line. The herbicide solution from the container is fed into the swivel bar and sprayed under the trees through the sprayers. When it meets the stem, the pivot bar deflects back, and then returns to its original position by the spring.

The disadvantage of the known device is that when the pivot bar bypasses the fruit tree and returns to its original position, a significant untreated zone remains behind the stem - a blemish. Damage by the pivot bar to young fruit trees is possible. In addition, the transfer of the sprayed solution of the herbicide by air streams to the cultivated plants is not excluded.

Known device for wetting near-stem zones with herbicides [2], containing a frame, a reservoir for herbicides and connected to it by pipelines swivel rods with holes and a fringe of bundles of fibers. At the moment of walking around the trunk of the tree, the bar rotates. After passing the stem, the bar returns to its original position.

The disadvantage of the known device is due to the formation of a blemish and damage to the bark of young trees when walking around the trunk with a pivot bar.

Known device for killing weeds [3], containing a frame, a reservoir with a fluid supply system and a rotary device with an apron in the form of a loop formed by telescopic generators with a longitudinal telescopic bar on which the sprayers are installed, while the rotary device has a hinge, a return spring and an adjustable stop connected to the frame. In operation, the rotary device is located between the trees in the near-trunk zone. When the rotary device contacts the stem, it rotates around the hinge axis, the spring is stretched and the rotary device leaves the row zone. After leaving the boom, it returns under the action of the spring to its original position up to the adjustable stop.

The disadvantage of this device is due to the formation of a blemish and damage to the bark of young trees when bypassing the trunk with a rotary device.

Known device for introducing herbicide solutions into the near-stem strip of the garden [4 - prototype], containing a frame, a reservoir with a system for supplying working fluid, a deflecting lever with sprayers and a protective casing made in the form of a disk with a shell on which an apron made of elastic material is fixed. The disc is mounted on a deflection arm by means of a hollow shaft, with the possibility of rotation. The herbicide solution flows through the hollow shaft to the sprayers. In operation, the deflecting lever with sprayers is located between the trees in the near-trunk strip. Upon contact with the tree trunk, the spring-loaded lever deflects and the cover leaves the row area. In this case, the disc rolls over the stem. After the disc comes off the stem, the deflecting lever returns to its original position. A deflecting lever and a rotating cover protect the stem from mechanical damage.

The disadvantage of the known device for introducing herbicide solutions into the near-trunk strip of the garden is due to the formation of a blemish after the protective casing leaves the tree trunk due to the inertia of the structure and the impossibility of quickly returning the deflecting lever with the casing to its original position. Elimination of this disadvantage by increasing the spring stiffness of the deflection arm leads to damage to the tree boles.

The problem solved by the proposed utility model is to develop a device that ensures high-quality introduction of herbicides into the near-trunk strip of the garden. The technical result from the solution of the task is to implement the possibility of reducing the blemish when bypassing the trunk and eliminating damage to cultivated plants.

The technical result is achieved in that a device for introducing herbicide solutions into the near-trunk strip of the garden, containing a frame, a reservoir with a system for supplying working fluid, a deflecting spring-loaded lever with sprayers and a protective casing mounted on the said lever with the possibility of rotation around a hollow shaft, and made in the form a disk with a shell, on which an apron made of elastic material is fixed, differs in that the disk of the protective casing is equipped in the center with a round window, above which a shutter is mounted, which provides overlap of the window contour and is rotatably fixed to the hollow shaft. The disk of the protective casing and the shutter are interconnected by means of elastic elements with the possibility of their first actuation, located radially and at an angle to the axis of rotation of the shutter, and the attachment point of each elastic element on the disk is located below its attachment point on the shutter.

The presence of a window in the disk of the protective casing in conjunction with a shutter located above the window and the connection of the disk of the protective casing with the shutter by means of elastic elements provide a decrease in blemish when bypassing the boom by reducing the time for returning the device to its original position from the joint movement of the deflecting lever and the protective casing relative to the mentioned lever.

The presence of elastic elements in the connection between the protective casing disk and the damper with the possibility of their priority actuation when the protective casing meets the stem ensures obstacle bypass with a minimum load on the bark. In addition, the elastic elements compensate for vertical vibrations of the machine due to uneven soil, reducing the likelihood of damage to the boles. The radial arrangement of the elastic elements facilitates the orientation of the spray nozzles in the center of the protective casing in the initial state.

The arrangement of the elastic elements at an angle to the axis of rotation of the casing eliminates the loss of the herbicide solution at the point where the damper adjoins the disc of the protective casing.

FIG. 1 schematically shows a device for introducing herbicide solutions into the near-trunk strip of a garden, plan view; fig. 2 - the same, in section A-A in Fig. one; fig. 3 - position of the spring-loaded deflecting lever with a protective casing in front of the stem; fig. 4 - position of the deflecting lever and protective casing when bypassing the boom; fig. 5 - the position of the deflecting lever and the protective casing at the time of the termination of the impact on them of the boom; fig. 6 - the position of the deflecting lever and the protective casing after the completion of the bypass of the boom.

The device for introducing herbicide solutions into the near-trunk strip of the garden contains a frame 1 with a deflecting lever 2, equipped with a hinge 3, a spring 4 and a stop 5. Sprayers 7 are fixed on the lever 2 by means of a hollow shaft 6 7. Shaft 6 is fixed with a nut 8. There is a protective casing 9, including disk 10 with a shell 11 and a window 12. An elastic apron 13 is fixed on the shell 11. A shutter 14 is installed above the window 12 with the possibility of rotation on a bearing 15. The disk 10 of the protective casing 9 and the shutter 14 are interconnected by elastic elements 16. The elasticity of elastic elements 16 provides them the primary actuation when bypassing the trunk. The attachment point 17 of each elastic element 16 on the disc 10 is located below the point 18 of its attachment to the shutter 14. Fastening the elastic elements at an angle to the rotation axis of the casing 9 pushes the disc 10 to the shutter 14 and eliminates the gap between them. The herbicide solution is supplied to the nozzles 7 through the nozzle 19 and the hollow shaft 6.

In operation, the deflecting lever 2 with spray nozzles 7 is located between the trees in the near-trunk strip. The outer edge of the protective cover 9 partially extends beyond the row line. When the protective casing 9 contacts the tree, the disc 10 with the shell 11 leaves the row of plants, rolling over the surface of the stem 20. The protective apron 13 protects the stem 20 from herbicides. Within the size of the window 12, the displacement of the disc 10 of the protective casing 9 is compensated by the deformation of the elastic elements 16. Further, the lever 2 is deflected, stretching the spring 4. After the disc 10 comes off the stem, the deflecting lever 2 by the spring 4 returns to its original position until it stops 5. At the same time, under the action of elastic elements 16, the disc 10 of the protective casing 9 takes its initial position relative to the deflecting lever 2. The joint return of the deflecting lever 2 and the disc 9 of the protective casing 10 to its original position minimizes the likelihood of blemish formation when bypassing the boom. The vertical vibrations of the unit at the stem due to unevenness of the soil are compensated by the elastic elements 16, allowing for skewing at the point of contact between the disc 10 and the damper 14.

The effectiveness of the device for introducing herbicides into the near-trunk strip of the garden is achieved by a significant increase in the quality of work.
