Description

Technical Field

[0001] This utility model discloses a type of integrated lotus root digging machine that combines cleaning, digging, flushing, and harvesting. Background Technology

[0002] my country is the world's largest producer of lotus roots, and its lotus root industry holds an important position in the global market. According to relevant data, China's lotus root planting area exceeds 6 million mu (approximately 400,000 hectares), mainly concentrated in the middle and lower reaches of the Yangtze River.

[0003] Harvesting lotus roots is a major challenge. Traditional methods of digging lotus roots usually involve manual shovel digging or manual water jet digging. These methods are inefficient, labor-intensive, and can easily damage the lotus roots.

[0004] With the development of agricultural mechanization, people have begun to use machine-assisted methods, mainly float-type lotus root harvesters. Float-type lotus root harvesters require workers to stand in the water and push the machine, which doesn't significantly reduce labor intensity, has low efficiency, and requires high water pressure, easily damaging the lotus roots. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated lotus root harvesting machine that combines cleaning, digging, flushing, and harvesting, in order to solve the problems of low work efficiency, high labor intensity, and easy damage to lotus roots mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: an integrated lotus root harvesting machine that combines cleaning, digging, flushing, and harvesting, comprising: a cleaning mechanism, a flushing mechanism, a hull, a rudder, a collection mechanism, a collection basket, a power mechanism, and a control box. The cleaning mechanism is installed at the front of the hull, the rudder is installed on the outer plates of both sides of the hull, the collection mechanism is located at the rear of the hull, the collection basket is attached to the tail of the collection mechanism, the power mechanism is located inside the hull, and the control box is located at the front of the hull.

[0006] Furthermore, the dredging mechanism includes: blades, a first roller, an electric thrust rod, a first support arm, a first large synchronous pulley, a first small synchronous pulley, and a first synchronous belt. The blades are mounted on the first roller, which is driven to rotate by the first synchronous belt, the first large synchronous pulley, and the first small synchronous pulley. The rotation of the first roller drives the blades to rotate, clearing lotus leaves, lotus stems, and weeds, and removing silt to form a backward sloping water flow. The electric thrust rod can adjust the angle of the first support arm to control the dredging depth of the blades.

[0007] Furthermore, the flushing mechanism includes: a water gun, a lead screw, a reciprocating connector, a helical gear, a chain, a water pump, a water pipe, a support rail, and a motor. The water pump draws water from the stern of the hull, pressurizes it, and sends it to the water gun through the water pipe. The water gun sprays high-pressure water downwards to flush away the silt and make the lotus root float to the surface. The motor rotates the lead screw, which drives the water gun to move up and down to adjust the water gun's immersion depth. The support rail supports the water gun and its fixing components, facilitating the water gun's left and right movement. The helical gear drives the chain to rotate, and the chain drives the reciprocating connector, causing the water gun to reciprocate left and right.

[0008] Furthermore, the collection mechanism includes: a second support arm, a collection claw, a second roller, a circular baffle, a second small synchronous pulley, a second large synchronous pulley, a second synchronous belt, and a transfer toothed rack. A single row of collection claws is installed on the roller, which is driven to rotate by the synchronous belt and the synchronous pulley. The rotation of the roller drives the collection claws to rotate, and the collection claws can collect the floating lotus roots into the collection basket through the transfer toothed rack.

[0009] Furthermore, the power mechanism includes a diesel engine and a pulley assembly. The pulley assembly enables speed reduction and transmission, transferring the power from the diesel engine to the cleaning mechanism, the flushing mechanism, and the collection mechanism.

[0010] Furthermore, the rudder is driven by a high-torque rudder motor and can rotate horizontally from 0° to 90°. The rudder can control the direction of the water flow, thereby changing the direction of the boat's forward movement and assisting in adjusting the forward speed, as well as helping to discharge lotus leaves, lotus stems, weeds and silt to both sides of the boat.

[0011] Furthermore, the control box contains a controller and a battery. The hull can be moved forward, turned, and the water depth of the dredging mechanism's drum can be controlled via buttons on the control box panel.

[0012] The beneficial effects of this utility model are: 1. The integrated design of clearing, digging, flushing, and harvesting ensures high work efficiency. Workers can operate while seated on the hull, avoiding standing in the water, thus improving the working environment for lotus root harvesting and reducing labor intensity.

[0013] 2. In addition to removing lotus leaves, lotus stems and weeds, the cleaning mechanism can also remove silt to a depth of 10-20cm and discharge the silt to both sides of the boat, which can greatly reduce the water pressure of the water gun and avoid damaging the lotus roots due to excessive water pressure.

[0014] 3. The water gun mechanism allows the water gun to move up, down, left, and right, covering a wide washing area and improving the efficiency of lotus root harvesting. Attached Figure Description

The first drum 102 is hollow. The six blades 101 are evenly divided into three blade groups, and the six blades 101 are equidistantly installed on the first drum 102. The two blades 101 in each blade group are axially symmetrical about the axis of the first drum 102. The two blades 101 in the first blade group are both U-shaped and are symmetrically installed vertically at the center of the first drum 102.
