Description

Technical Field

[0001] This utility model relates to a soil loosening device for a scallion ridging machine, belonging to the field of scallion ridging machines. Background Technology

[0002] Currently, most existing scallion ridging machines are dedicated to ridging only and have limited functionality. For example, they lack furrow loosening devices and can only rid the soil, not simultaneously furrow and loosen the soil, which is detrimental to the growth and management of scallions. To improve this unfavorable situation and the current inefficiency, this utility model proposes a new technical solution. Utility Model Content

[0003] The technical solution proposed in this utility model is a soil loosening device for a scallion ridging machine, which includes: an external ridging machine frame, an external gearbox device, an external gearbox device frame, an external ridging disc shaft, an external ridging disc, an upper cylinder seat, a cylinder, a lower cylinder seat, an external large sprocket, an external small chain drive sprocket, an external large chain, a rotary tiller cover frame, a rotary tiller cover, a rotary tiller disc, a rotary tiller, a bearing, a rotary tiller shaft, a rotary tiller shaft sprocket, an external small chain, a lower rotary tiller support, a lower connecting plate, a hinge or joint, a connecting piece, an upper connecting plate, and an upper rotary tiller support. An upper cylinder seat is located on the external ridging machine frame and perpendicularly corresponding to the center of the two external ridging discs. The upper cylinder seat is connected to the upper end of the cylinder, and the cylinder has two oil inlets and outlets. Two oil pipes are connected to an external oil pump. The lower end of the oil cylinder is connected to the lower cylinder seat, which in turn is connected to the rotary tiller blade cover frame. The rotary tiller blade cover frame is mounted on the rotary tiller blade cover and connects to both sides of the rotary tiller blade frame. A rotary tiller shaft is mounted on the lower rotary tiller support, a rotary tiller disc is mounted on the rotary tiller shaft, and rotary tillers are mounted on the rotary tiller disc. Bearings are mounted on the outer side of the rotary tiller cover frame and on the rotary tiller shaft. A small sprocket is mounted on one end of the rotary tiller shaft. One end of the lower rotary tiller support is connected to both ends of the rotary tiller shaft, and the other end of the lower rotary tiller support is connected to a lower connecting plate. The lower connecting plate is connected to the lower part of a hinge or latch by welding, and the upper part of the hinge or latch is connected to an upper connecting plate by bolts or welding. The upper part of the upper connecting plate is connected to one end of the upper rotary tiller support. The upper end of the rotary tiller blade support is welded to the external ridging machine frame. The lower part of the rotary tiller blade support connects to the upper part of the upper connecting plate, avoiding the external ridging disc shaft. The external ridging disc shaft can be equipped with an external ridging disc, an external large sprocket, and a small sprocket. An external large chain is installed on the external large sprocket, which can be connected to the transmission sprocket device of the external gearbox. A small chain is installed on the external small chain power sprocket and the rotary tiller shaft sprocket, which can be connected to the rotary tiller shaft sprocket on the rotary tiller shaft.

The rotation of the external large chain causes the external ridging disc, external large sprocket, external small chain drive sprocket, and rotary tiller shaft sprocket to rotate together. The rotary tiller shaft sprocket drives the rotary tiller shaft, bearings, rotary tiller disc, and rotary tiller blades to rotate simultaneously. When the hydraulic cylinder retracts, the lower end of the hydraulic cylinder moves upward and retracts, pulling the lower seat of the hydraulic cylinder upward. The lower seat of the hydraulic cylinder pulls the rotary tiller blade cover frame upward, and the rotary tiller blade cover frame drives the rotary tiller blade cover upward. At the same time, the lower connecting plate, hinge, or flipping connected to the upper end of the rotary tiller blade lower support rotates or flips, so that the rotary tiller blade lower support and the rotary tiller blade upper support form an angle. At this time, the rotary tiller shaft, rotary tiller disc, rotary tiller blade, and rotary tiller shaft sprocket move upward together and leave the tilled soil.When the hydraulic cylinder extends, its lower end moves downwards, pulling the lower cylinder seat downwards. This, in turn, pulls the rotary tiller blade cover frame downwards, causing the rotary tiller blade cover to move downwards. Simultaneously, the lower connecting plate, hinge, or rotating mechanism connected to the upper end of the rotary tiller blade support rotates or flips, creating an angle between the lower and upper rotary tiller blade supports. At this point, the rotary tiller blade cover frame, along with the rotary tiller blade cover, rotary tiller shaft, rotary tiller disc, rotary tiller blades, and rotary tiller shaft sprocket, move downwards together, allowing the rotary tiller to loosen and furrow the soil.
