The rocker and the ratchet are coaxially installed. The ratchet pushes the ratchet shaft sprocket to rotate intermittently, and the ratchet shaft sprocket drives the crankshaft through the chain. The hole-making shaft sprocket rotates, and the hole-making device on the hole-making shaft rotates intermittently to complete hole-making; compared with the existing technology, the present invention uses a crank rocker mechanism and a ratchet mechanism to realize the intermittent hole-making function, and the hole-making spacing can be adjusted by transmission ratio to achieve.

Description

Transplanter intermittent drilling device

Technical field

The invention belongs to the field of agricultural machinery, and particularly relates to an intermittent hole drilling device for a transplanting machine, which is used for soil hole drilling operations before crop transplantation.

Background technique

Seedling transplanting can save seeds, improve crops' ability to resist disease and cold, effectively extend the growth period of crops, and increase crop yields. In order to imitate the steps of manual transplanting, step-by-step transplanting can be used, that is, special machines are used to dig holes and provide supporting equipment. Seedlings are planted manually or mechanically; the intermittent hole drilling device of the transplanter is a special equipment for step-by-step transplanting, which can drill holes according to the specified plant spacing requirements.

Contents of the invention

The invention provides an intermittent hole drilling device for a transplanting machine, which can complete hole drilling operations during step-by-step transplantation of crops.

The technical solution of the present invention is that the intermittent drilling device of the transplanting machine includes a drilling shaft sprocket, a frame, an input sprocket, a ratchet tongue, a ratchet wheel, a ratchet shaft sprocket, a connecting rod, a ratchet shaft, a crank shaft, and a drilling shaft. The shaft, hole drill, crank, and rocker; the ratchet shaft, crank shaft, and hole drilling shaft are installed on the frame; the input sprocket and the crank are fixedly installed on both ends of the crank shaft, and a connecting rod is installed between the crank and the rocker; The ratchet and the rocker are respectively fixedly installed at both ends of the ratchet shaft; power is input from the input sprocket, which drives the crank to make a circular motion and drives the rocker to swing; the ratchet shaft sprocket is coaxially installed with the ratchet and is adjacent to the ratchet. The tongue is installed on the ratchet shaft sprocket; the hole drilling shaft sprocket is installed on the end of the hole drilling shaft, and the hole drilling device is installed on the hole drilling shaft; the ratchet pushes the ratchet shaft sprocket to rotate intermittently, and the ratchet shaft sprocket drives the hole drilling through the chain The shaft sprocket rotates, and the hole drilling device on the hole drilling shaft rotates intermittently, and hole drilling is completed when the hole drilling device is downward. The rotation direction of the hole drilling device is the same as the rotation direction of the ground wheel.

Compared with the prior art, the present invention uses a crank rocker mechanism and a ratchet mechanism to realize the intermittent drilling function, and the drilling spacing can be realized by adjusting the transmission ratio.

Detailed ways

The present invention will be described in further detail below with reference to the accompanying drawings.

As shown in Figures 1, 2, and 3, the intermittent drilling device of the transplanter includes a drilling shaft sprocket 1, a frame 2, an input sprocket 3, a ratchet tongue 4, a ratchet 5, a ratchet shaft sprocket 6, Connecting rod 7, ratchet shaft 8, crank shaft 9, drilling shaft 10, drilling device 11, crank 12, rocker 13; ratchet shaft 8, crank shaft 9, drilling shaft 10 are installed on the frame 2; input chain Wheel 3 and crank 12 are respectively fixedly installed at both ends of crankshaft 9, and connecting rod 7 is installed between crank 12 and rocker 13; ratchet 5 and rocker 13 are respectively fixedly installed at both ends of ratchet shaft 8; power is input from sprocket 3 Input, the input sprocket 3 drives the crank 12 to make a circular motion and drives the rocker 13 to swing; the ratchet shaft sprocket 6 is coaxially installed with the ratchet 5 and adjacent to the ratchet 5, and the ratchet tongue 4 is installed on the ratchet shaft sprocket 6; The end of the hole shaft 10 is installed with the hole drilling shaft sprocket 1, and the hole drilling device 11 is installed on the hole drilling shaft 10; the ratchet 5 pushes the ratchet shaft sprocket 6 to rotate intermittently, and the ratchet shaft sprocket 6 drives the hole drilling shaft chain through the chain. The wheel 1 rotates, and the hole drilling device 11 on the hole drilling shaft 10 rotates intermittently, and hole drilling is completed when the hole drilling device 11 is downward. The rotation direction of the hole drilling device 11 is the same as the rotation direction of the ground wheel.

The above-mentioned embodiments are only preferred embodiments of the present invention and are not intended to limit the implementation of the present invention. For practitioners in the field, it is not necessary and impossible to make other changes or modifications in different forms based on the above descriptions. All implementations are exhaustive, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
