The invention discloses a wooden horse toy. The wooden horse toy comprises a wooden horse body, a base seat and a supporting rod used for supporting the wooden horse body on the base seat in a balanced mode, wherein an elastic element is connected between the wooden horse body and the supporting rod. The wooden horse toy further comprises a rotation shaft which at least partially extends into the wooden horse body and rotates through the driving of a power device, wherein the rotation shaft is fixed on the fixing rod through a radial bearing. A first contact part is arranged in the wooden horse body, a second contact part used for driving the first contact part to swing intermittently is arranged on the rotation shaft, the rotation shaft drives the second contact part to rotate, and shifts the first contact part to swing towards one side when the second contact part contacts the first contact part, so that the wooden horse is driven to swing towards one side, when the second contact part rotates to leave the first contact part, the elastic element force the wooden horse body to return, the cycle repeats, and the swinging of the wooden horse body is achieved.

The invention discloses a toy which comprises a toy body, a base and a supporting rod. The toy body is supported on the base through the supporting rod in a balanced mode, an elastic element is connected between the toy body and the supporting rod, a rotary shaft driven by a power device to rotate is arranged in the toy body, and fixed to the supporting rod through a radial bearing, a first contact piece is arranged in the toy body, and a second contact piece for pushing the first contact piece to swing intermittently is arranged on the rotary shaft. The rotary shaft rotates to drive the second contact piece to rotate, and when the second contact piece is in contact with the first contact piece, the first contact piece is shifted to swing towards one side, and therefore the toy body is driven to swing towards one side. When the second contact piece rotates away from the first contact piece, the elastic element forces the toy body to reset, and the process is circulated in the same way, so that the toy body swings.

The invention provides a soil breaking and loosening device for planting ground, which comprises a frame, rollers, a soil loosening mechanism, a No. 1 cylinder, a moving slider, a lifting cylinder and a soil breaking mechanism. The invention provides a planting ground breaking and loosening device, which can solve the following problems in the process of planting ground breaking and loosening: a. The traditional planting ground breaking and loosening generally relies on manual use of simple tools to break and loosen the soil, This kind of farming method is labor-intensive and takes a lot of time, so it is not suitable for large-scale soil-breaking and loosening; b. The loosening equipment on the market is not only expensive, but also has a single function of this device, which can often loosen the soil. However, the device cannot crush the soil and refine the soil. At the same time, it cannot effectively remove the weeds in the soil. Often the weeds still grow on the places where the soil has been broken and loosened, and it needs to be cleaned manually. This does not reduce the need for manual labor. strength.

The invention provides a conveyor-belt-type tooth-washing device, relating to the field of the dental department. The conveyor-belt-type tooth-washing device comprises a box, a transmission mechanism and a bracket, wherein the box is mounted on the transmission mechanism, the bracket is placed on one side of the transmission mechanism, the box is mounted on a box fixing board, the box fixing board is arranged on the top of an internal attaching plate, the internal attaching plate is fixed on a conveyor belt, the box fixing board is provided with a third motor for adjusting the angle of the box, the transmission mechanism comprises a mounting flat plate, rolling wheels, sliders, the conveyor belt, two rollers, a first motor and first sliding rails, the two rollers are arranged on the mounting flat plate, and are connected through the conveyor belt, the plurality of first sliding rails are fixed to the mounting flat plate, the two sliders are arranged on the first sliding rails, and the rolling wheels are arranged on the sliders, and are tangent to the conveyor belt. With the conveyor-belt-type tooth-washing device, the automatic tooth-washing purpose can be realized, a user can complete the tooth washing operation independently, and thus the danger of cross infection from others is avoided.

The invention relates to an automatic cold press. The automatic cold press comprises a frame, an upper pressure head base, an upper pressure head, a lower pressure head base, a lower pressure head, a worktable, a mold cavity arranged on the worktable and matched with the upper pressure head and the lower pressure head, a feeding device, a supply device for driving the feeding device to move to the mold cavity, and a driving mechanism for driving the upper pressure head and the lower pressure head to move up and down; a position of a discharge port of the feeding device corresponding to the mold cavity is a first station; a position of the discharge port of the feeding device leaving from the mold cavity is a second station; and the supply device has a first driving part for driving the feeding device to perform a reciprocating motion between the first station and the second station, and a second driving part for driving the feeding device to perform a reciprocating motion nearby the first station. After the technical scheme is adopted, the second driving part drives the feeding device to perform the reciprocating motion nearby the first station, so that the shaking effect of the feeding device is realized, the uniform falling of powder into the mold cavity is realized, and the cold pressing quality of products is promoted.
