Description

The utility model relates to agricultural engineering, in particular to machines for digging seedlings and seedlings of fruit, berry, forest and ornamental crops.

Known excavating mounted plow VPN-2 [Mechanization of work in horticulture / V.K. Kuteinikov, N.P. Losev, A.V. Chetvertakov and others - 2nd ed., revised. and additional - M.: Kolos, 1983. 319 s - p. 134], which is intended for digging up one- and two-year-old seedlings of fruit, berry and forest crops. The plow contains a frame on which a digging bracket is mounted, made in a U-shape with loosening plates bent upwards fixed in its rear part, a support wheel, a stability knife and a hitch.

The disadvantage of the known excavation plow is the low quality of crumbling of the soil layer.

A known machine for digging seedlings (see RF patent No. 203564, 04/12/2021 - prototype), containing a frame on which a stability knife, a hitch mechanism, a support wheel, a digging bracket with a plowshare, made in a U-shape, from the rear side which are fixed extensions and a drive in the form of a crank mechanism.

A significant disadvantage of the specified working body for digging seedlings is the low intensity of crumbling of the soil layer, due to the fact that during the execution of the work the rippers move synchronously with the same amplitude of oscillation.

The technical result of the proposed utility model is to improve the quality of crumbling of the soil layer.

The technical result is achieved by the fact that in the digging machine for nurseries, containing a frame on which a stability knife is installed, a hitch mechanism, a support wheel, a digging bracket with a plowshare, on the back of which extensions are fixed and a drive containing a crank and a connecting rod with a bent section, according to utility model, on the bent section of the connecting rod, eccentric cams are installed with the possibility of adjusting their position relative to the extensions fixed above them.

The novelty of the claimed technical result lies in the fact that due to the use of eccentric cams, during operation, the rippers can make both multidirectional and identical oscillations, which in turn improves the quality of crumbling of the soil layer.

The proposed utility model is industrially applicable and can be used for digging seedlings and seedlings of fruit, berry, forest and ornamental crops.

The essence of the proposed technical solution is illustrated by the drawing, where

in fig. 1 shows a nursery digging machine, front view;

figure 2 is the same, side view.

The digging machine for nurseries includes a frame 1, on which a stability knife 2, a hitch mechanism 3, a support wheel 4 and a digging bracket 5 with a plowshare 6 are installed. with a bent section 10. On the bent section 10 of the connecting rod 9, eccentric cams 11 are installed with the possibility of adjusting their position relative to the extensions 7 fixed above them.

The eccentric cams 11 are mounted on the bent section 10 with the possibility of their rotation in order to regulate the intensity of vibrations of the extensions 7.

Digging machine for nurseries works as follows.

Before starting work, the digging machine for nurseries is aggregated using a linkage mechanism 3 with a power source. During the working stroke, the drive is turned on, containing the crank 8 and the connecting rod 9, to create vibrations on the extensions 7, and the digging bracket 5 with the ploughshare 6 are buried in the soil. Ploughshare 6 pre-cuts a narrow layer of soil and directs it to the digging bracket 5. The digging bracket 5 cuts off the soil layer in the horizontal and vertical plane and moves it along its working surface. Then the soil layer with the seedling moves to the extensions 7, which, due to the drive, consisting of a crank 8 and a connecting rod 9 with a bent section 10, make intense vibrations. Due to the interaction of the eccentric cams 11 with the extensions 7, the latter begin to make multidirectional or identical oscillations, as a result of which the soil layer is actively destroyed, and the connection between the root system and the soil is broken. Eccentric cams 11 can be set to various positions, which allows you to adjust the amplitude of oscillations of the rippers 7.

Claims (1)

Digging machine for nurseries, comprising a frame on which a stability knife is installed, a linkage mechanism, a support wheel, a digging bracket with a share, made in a U-shape, on the rear side of which extensions are fixed and a drive containing a crank and a connecting rod with a bent section, different by the fact that eccentric cams are installed on the bent section of the connecting rod with the possibility of adjusting their position relative to the extensions fixed above them.
