Description

Swing type lotus root digging device

Technical Field

The invention belongs to the technical field of underwater plant harvesting, and particularly relates to a swing type lotus root digging device.

Background

In the silt of lotus root growth in aquatic, to the collection of lotus root, the method of artifical manual collection is adopted now more, has wasted a large amount of labours promptly, and efficiency is low again, still easily receives the influence of weather in the collection process, and the lotus root that comes too late to pick rotten in the pond has both caused a large amount of wasting of resources, has also seriously influenced the planting income of grower. Meanwhile, workers need to operate in water or sludge in the collecting process, and the bodies of the collecting workers are extremely easy to be injured.

Therefore, chinese patent CN203226040U discloses a lotus root digging machine, which comprises a tractor head, the front section of the tractor head is connected with a lotus root digging machine component through a liftable connecting device, the lotus root digging machine component is connected with a water pump and a water tank, the lotus root digging machine component comprises a connecting frame, a conveying device vertical rod, a vehicle body component composed of cross beams, and stem cutting devices connected in sequence, a brush roller with brush bristles, a conveying belt, a water spraying component and a shovel plate, the stem cutting devices are arranged at the foremost end of the vehicle body component through the cross beams, the brush roller and the water spraying component are arranged between the two cross beams, and the water spraying component is composed of an upper row of spray pipes and a lower row of spray pipe swinging devices.

However, the above patent has the following problems: because the brush roll only can brush the surperficial one deck silt of lotus root, consequently can't clear up the silt of lotus root week side, lead to the lotus root still to sink into and need use the shovel board to shovel out the lotus root in the silt, the shovel board can cause the damage to the lotus root when shoveling the lotus root.

Disclosure of Invention

Therefore, the invention provides a swing type lotus root digging device which is used for cleaning mud on the periphery of lotus roots for cleaning.

In order to achieve the purpose, the scheme of the invention is as follows:

the swing type lotus root digging device comprises a vehicle body, a water pumping pipe is fixedly connected to the vehicle body, a water pump is arranged on the water pumping pipe, a top rod and a fixed rod are further fixedly arranged on the vehicle body, a water through hole communicated with the water pumping pipe is formed in the fixed rod, a sliding groove is circumferentially formed in the fixed rod, a sliding block is slidably connected in the sliding groove, a swing arm is hinged to the sliding block, a rotating rod is fixedly connected to one end, away from the sliding block, of the swing arm, a water outlet hole is formed in the rotating rod, a hose is connected between the rotating rod and the fixed rod, one end of the hose is communicated with the water through hole, the other end of the hose is communicated with the water outlet hole, a water wheel is rotatably connected to the water outlet hole and is used for driving the rotating rod to rotate, a cam is coaxially, and a piston cylinder communicated with the pressurizing opening is fixedly arranged on the rotating rod, a piston is connected in the piston cylinder in a sliding manner, a piston rod is fixedly connected to the piston, and the piston rod is fixedly connected with the baffle.

The technical principle of the invention is as follows:

inserting the rotating rod into the lotus root field, after the rotating rod contacts lotus roots, turning on the water pump, pumping water into the water through holes by the water pumping pipe, enabling water flow in the water through holes to flow through the hose and finally enter the water outlet holes, and enabling the water wheels to rotate by water power when the water flow enters the water outlet holes due to the fact that the water outlet holes are internally provided with the water wheels, enabling the water wheels to rotate to drive the rotating rod to rotate, enabling the cleaning balls at the end portions of the rotating rod to rotate around the lotus roots, and cleaning sludge around the lotus; because the spray head is abutted against the baffle plate and the rotating rod is provided with the pressurizing port communicated with the water outlet hole, water flow is blocked and flows into the pressurizing port, the water pressure in the pressurizing port is increased, the piston is pushed to move, and then the piston rod is driven to move upwards; because fixedly connected with swing arm on the dwang, therefore the dwang rotates, the swing arm rotates along with the dwang, the swing arm drives the slider and rotates along the spout on the dead lever, because the coaxial cam that is provided with on the dwang, therefore the dwang rotates, the cam rotates, the dwang is driven to the downswing when cam and ejector pin offset, when the cam rotates to not offsetting with the ejector pin, the swing arm drives the dead lever under the effect of torsional spring and resets, accomplish reciprocal swing, silt about the lotus root all clears up, the lotus root is collected because buoyancy floats the surface of water after the silt clearance about with lotus root week side and from top to bottom.

The invention has the beneficial effects that:

1. the shower nozzle is provided with the baffle outward, with direct stretch into the shower nozzle among the prior art in the silt, the shower nozzle is when stretching into silt along with the dwang, and the baffle blocks that silt in the lotus root field gets into and blocks up the shower nozzle in the shower nozzle, ensures the normal work of shower nozzle.

2. Compared with the prior art that the brush roller only cleans sludge on the surfaces of the lotus roots, the brush roller can clean the sludge on the periphery and up and down of the lotus roots, and the cleaning effect is better.

The first preferred scheme is as follows: preferably, the vehicle body is also fixedly provided with a stem cutting rod, and the end part of the stem cutting rod is detachably connected with a stem cutting knife. When digging the lotus root device and walk in the lotus root field, set up and cut the stem sword and can cut off the stem leaf of lotus root, avoid the lotus root stem leaf to obstruct the sight also position through the position determination lotus root stem leaf simultaneously, the operating personnel of being convenient for operates.

The preferred scheme II is as follows: preferably, a spring is connected between the piston and the inner wall of the piston cylinder. A spring is connected between the piston and the piston cylinder, when the device is not used any more, the speed of piston resetting is accelerated, the baffle falls down again to abut against the spray head, and the spray head is prevented from being blocked by foreign matters.

The preferable scheme is three: preferably, the surface of the cleaning ball body is coated with a flexible material. Because the cleaning ball need be cleared up silt all around the lotus root, set up flexible material and can avoid the cleaning ball when contacting the lotus root body, cause the damage to the lotus root body.

The preferable scheme is four: preferably, a water passage is provided in the vehicle body, and the water passage communicates between the water through hole and the water outlet hole. Set up in the automobile body with water channel, compare and use the hose outside the car with limbers and apopore intercommunication, can avoid the dolly to walk in silt when, the hose is punctured to the sharp-pointed hard thing of the stone in the silt, influences water efficiency.
