The cassette 8 (Fig. 1, Fig. 2, Fig. 3) for targets is placed on the base plate 9 (Fig. 1, Fig. 2, Fig. 3, Fig. 4) made with a hole 10 (Fig. 1, Fig. . 3, Fig. 4) to drop the target onto the cast plate 11 (Fig. 1, Fig. 2, Fig. 3, Fig. 4) installed under the blade 12 (Fig. 1, Fig. 3, Fig. 4, Fig. 5) to eject the target. On the base plate 9 there is a cutter 13 (Fig. 1) of the target from the stack. The system for rotating the cassette at a certain angle includes a lever 14 (Fig. 1, Fig. 3) of the gearbox 3 connected in series, a rod 15 (Fig. 1, Fig. 3), a lever 16 (Fig. 1, Fig. 3), fixed in the lower part of the shaft 17 (Fig. 3), on which the rear pusher 18 is fixed in its upper part (Fig. 1, Fig. 3). The machine includes a pusher 19 (Fig. 4) of the blade 12, located in the upper part of the main shaft 20 (Fig. 5). The system for transmitting torque from the gearbox 3 to the main shaft 20 includes a lever 14 of the gearbox 3, located on the main shaft 20 in its lower part, the lever 21 (Fig. 3, Fig. 4), on which by means of the hook 22 (Fig. 3, Fig. 4) the spring is fixed 6. The braking device for the blade includes a bushing 23 (Fig. 3, Fig. 4, Fig. 5) with a system of bearings through which the main shaft 20 passes. In a particular embodiment, the bushing 23 is made with a system of three bearings 24 (Fig. 5), 25 (Fig. 5), 26 (Fig. 5), sequentially located one after another. In addition, the braking device includes a ratchet mechanism that includes a pawl 28 (Fig. 4) placed on the platform 27 (Fig. 4) of the sleeve 23, made with the possibility of free rotation about an axis with a screw-in plug 29 (Fig. 4), and a toothed ring 30 (Fig. 4, Fig. 5) located on the main shaft 20 between the pusher 19 and the bushing 23.

In a particular embodiment, the machine contains a release button 31 (Fig. 6, Fig. 7) of a spring 6 and a limit switch 32 (Fig. 4, Fig. 5) fixed under the cast plate 11 at the point where the target falls out. The release button 31 of the spring 6 can be placed in the electric box 4.

In a private embodiment, the machine is equipped with a remote control 33 (Fig. 7), on which the release button 31 of the spring 6 is located, and the electric box 4 has a connector 34 (Fig. 7) for connecting it.

The machine for throwing bench targets operates from a power source, in particular a battery with an electric voltage of 12 V. There are two operating modes of the machine: automatic and manual.

In automatic mode, when the toggle switch 5 is turned on, current is supplied to the motor 2, which leads to the rotation of the lever 14 of the gearbox 3. The rotation of the lever 14 is transmitted through the rod 15 and the lever 16 to the shaft 17, which drives the rear pusher 18, which in turn turns the cassette 8 at a strictly defined angle. The cassette 8 advances the stacks of targets so that one of the stacks is located above the hole 10. The cutter 13 separates the lower target from the stack, which through the hole 10 falls on the cast plate 11, while the rest of the targets in the stacks continue their circular motion.

At the same time, when the lever 14 rotates, it engages with the lever 21, which leads to the simultaneous rotation of the main shaft 20 and tension of the spring 6, since it is fixed on the lever 21 by means of the hook 22. Due to the rotation of the main shaft 20, the pusher 19 drives the blade 12 in motion and brings it to the target on the cast plate 11. With further rotation of the lever 14, it is disengaged from the lever 21, after which the release of the spring 6 causes the main shaft 20 to rotate and the target is ejected from the cast plate 11 by means of the blade 12. After the blade 12 is released by inertia makes a rotation, which is extinguished by the spring 6.

The system of bearings located inside the sleeve 23 ensures the transmission of rotation and the coaxiality of the main shaft 20. When the spring 6 is released, the vibrations occurring in it are transmitted to the main shaft 20. The ratchet mechanism, including the pawl 28, limiting the movement of the gear 30 in the opposite direction, dampens the vibrations by converting the reciprocating motion of the main shaft 20 into an intermittent rotary motion in one direction and thereby prevents the vane 12 from rotating in the opposite direction.

In the manual mode, the targets are ejected in a cycle, while the operating principle of the machine is similar to the automatic mode until the moment when the pusher 19 brings the blade 12 to the target on the cast plate 11. This position of the blade 12 is the starting position. Further rotation of the lever shaft 14 causes the pusher 19 to touch the limit switch 32 installed under the cast plate 11 at the point where the target falls out, and to open the electric circuit of the motor 2 with the gearbox 3, while the levers 14 and 21 remain in engagement. By moving the limit switch 32, the position of the blade 12 is set, which eliminates the gap between it and the target on the cast plate 11. The machine is ready to eject the target. When the release button 31 is pressed, the electric circuit of the motor 2 is closed with the gearbox 3 and the target is ejected similarly to the automatic mode, after which the limit switch 32 is triggered again. This completes the cycle and the machine is ready for the next target ejection.

In order to increase convenience, the target can be ejected using the remote control 33, which is connected to the connector 34 on the electric box 4.

The design of the sleeve with a system of three bearings provides an optimal area for transmission of rotation.

The use of a bushing with a system of bearings through which the blade pusher shaft passes, as well as a ratchet mechanism including a pawl located on the hub site, and a toothed ring located on the main shaft between the pusher and the bushing, makes it possible to increase the durability of the braking device due to manufacturability, simplicity of design and the reliability of these devices.
