Description

The invention relates to hand tools, in particular to shovels for excavation during gardening work.

The aim of the invention is to facilitate labor.

The drawing shows a General view of the shovel.

The shovel comprises a blade 1 with a holder 2, a handle 3 attached by a holder 2 to the blade 1, a sleeve 4, which has a rectangular groove perpendicular to the axis of rotation of the sleeve 4, and a coaxial hole. A rod 5 is mounted in the hole of the sleeve 4 by means of a threaded connection. The rod 5 is attached to the support element, which is made in the form of articulated jibs 6 and 7, connected by a spring 8 and having pivotally mounted support arms: suits 9. To the jibs 6 and 7 from the side of the hinge joint at certain distances attached squares 10, which limit the rotation of the jib 6 and 7 relative to each other. A lever 11 is attached to the end of the jib 7. On the handle 3, a rectangular plate 12 is fixed in the groove of the sleeve 4, which has a surface corresponding to the shape of the groove. The plate 12 has two rectilinear sections that are smoothly rotated 90 ° relative to each other. On the ends of the plate 12, annular stops 13 and 14 are fixed. The blade 1 has supporting edges 15. The handle 3 is made with a handle 16, and the lever 11 is made with a handle 17. To increase the rigidity, the console 18 is attached to the jib 6, the free end of which is connected with rod 5.

Work with a shovel is carried out as follows.

The supporting element of the shovel with disks 9 is mounted on the ground. With one hand, for example, with the left, the worker grabs the handle 17, and with the other - the handle 16 and lifts the handle 3 to the stop of ring 13 into the sleeve 4, after which the handle 3 tilts to itself at an angle of 70-80 ° to the ground plane, In this position of the handle 3, the plate 12 is in the groove of the sleeve 4 with its lower straight portion and the blade 1 is turned by its plane towards the working one. Then, the blade 1 is lowered to the ground and the ground is embedded by pressing the foot on the support face 15. In this case, the handle 3 moves downward and the plate 12 moves into the groove of the sleeve 4 with its lower rectilinear section. After the blade 1 has completely penetrated into the ground, the worker starts to pull the stalk 3 on itself, which with the sleeve 4 rotates around the rod 5, as a result of which the blade 1 with the ground rises. Then, by pressing the hand on the handle 16 from

the handle 3 is pushed forward until the stop of the ring 14 into the sleeve 4. In this case, the plate 12, moving into the groove of the sleeve 4 with its curved section, expands the handle

With a blade of 1 at 90 ° and soil located

on blade 1, flips over. After that

handle 16 t nets and stalk 3

is returned to its original position, i.e. before

the stop ring 13 into the sleeve 4. Then, if

the worker working in the process moves to the right, pressing the lever 17 of the lever 11 downward by the hand, the jib 7 is lifted from the ground and pivots up to the stop of its upper part into the elbow 10 located on the jib 6.

5 The spring 8 is then stretched. Subsequent pressing the handle 17 to the right, the support element tilts to the right until the jib 7 stops against the support disk 9 in the ground. After that, by pushing the handle 17 upwards, the jib 6 is torn off 0 s from the ground, while the spring 8 is compressed and moves the jib 6, as well as the handle 3 with the blade 1 to the right, to the distance equal to the width of the blade 1. Subsequent pressing the handle 17 down the support element

5 tilts to the left until the jib 6 abuts against the support disk 9 into the ground.

If the worker in the process moves to the left, then by pressing the handle 17 down the jib 7 is lifted from the ground. On the

0, the support disk 9 of the jib 6 is placed on the foot of the worker to prevent the jib 6. To push the handle 17 to the left, the support element tilts to the left, and then by pushing the handle 17 up the jib 7 rotates until its angle 10 stops against the jib 6. In this case, the spring 8 is compressed. After that, the support element is tilted to the right and the i-jib 7 is lowered to the ground. The leg of the worker is removed from disc 9. B

0 as a result of further inclination of the support element, the jib 6 is opened from the ground, while the spring 8 is unclenched and moves the jib 6 with the handle 3 to the left by a distance equal to the width of the blade 1.

5 By further pressing the handle 17 downward, the support element is tilted to the left until the jib 6 stops against the support disk 9 in the ground.

Turning the soil with the proposed shovel is not rotation

0 cuttings with a blade, as in a well-known shovel, and by pressing the cuttings and pushing them forward from themselves, which is less difficult. Rearrange shovels with. a lever-articulated walking device that does not require tangible inclinations and turns of the worker is more convenient and therefore also less difficult. This facilitates labor and helps to increase labor productivity.

Claims (1)

The claims of spring-bound jibs having Shovel, including blade with power-ends pivotally mounted supporting coy and handle, articulated discs, on the side of the articulation a supporting element, distinguishing to the jibs is attached limiters in the sense that, in order to endow labor, the hinge-5 of the gate in the form of squares, to the end of one of The connection is made in the form of a sleeve, the lever is attached to the jibs, and on the handle in having a rectangular groove and an opening, a plate having a perpendicular to its axis of rotation, in which is the surface corresponding to the shape of the groove, at rum by means of a threaded connection, its two rectilinear sections smoothly a rod is installed, the other end at-10 is rotated 90 ° relative to each other, fastened to the supporting element, the weights at the ends of the plate are fixed to the stops, which are angled in the form of articulated joints.
