Description

Technical Field

[0001] The utility model relates to the technical field of lotus root digging machines, in particular to an interception device for the water inlet of a lotus root digging machine. Background Technique

[0002] Lotus root, also known as lotus rhizome, is a kind of aquatic vegetable. The lotus root is thick and jointed in shape, with tubular small holes inside, and there are filaments connected after being broken. However, although lotus root is delicious, it is difficult to dig. For a long time, the picking and harvesting of lotus root have mainly relied on manual digging. However, manual digging not only has a high labor intensity and low production efficiency, but also causes relatively serious damage to the lotus root. A lotus root digging machine is a device for digging lotus root.

[0003] During the daily use of the lotus root digging machine, a high-pressure nozzle is usually used to wash the silt. However, the water supplied to the high-pressure water pump often contains waste such as floating withered lotus leaves and broken lotus stems, which will cause the water inlet to be blocked, reduce the water inlet speed of the water pump, and even cause damage to the high-pressure water pump, affecting the production efficiency.

[0004] The inventor found the following problems in the prior art during the implementation of the present utility model: 1. During the daily use of the existing interception device, the water supplied to the high-pressure water pump often contains waste such as floating withered lotus leaves and broken lotus stems, causing the water inlet to be blocked, reducing the water inlet speed of the water pump, and even causing damage to the high-pressure water pump, affecting the production efficiency; 2. During the daily use of the existing interception device, the nozzle structure is usually fixedly installed on the device and is inconvenient to adjust according to needs. A small number of nozzles will result in a small working width, while an excessive number of nozzles will result in a high cost. Content of the Utility Model

To achieve the above purpose, the present utility model provides the following technical solution: An interception device for the water inlet of a lotus root digging machine, including a machine body. Floats are installed on both sides of the bottom of the machine body. A handrail and a baffle are installed on one side surface of the machine body. A protective cover is installed on one side surface of the machine body. A nozzle assembly, a paddle assembly, and a swing assembly are installed on the inner wall of the machine body in sequence from left to right. An interception assembly is installed on the top surface of the machine body. A water inlet is installed on one side surface of the machine body. A high-pressure water pump is installed on the inner wall of the machine body. A water pipe is installed at one end of the high-pressure water pump.

[0006] The nozzle assembly includes fixed rods installed on both sides of the inner wall of the machine body. On one side surface of the fixed rods, mounting brackets are installed. On one side surface of the mounting brackets, slide rails are installed. A first fixing block is installed between the mounting brackets.

At both ends of the rocker, cranks are installed. A first connecting block is installed between the cranks. One end of the crank is installed with a first driving rod. One end of the first driving rod is installed with a first reduction motor.

[0007] The blade assembly includes a fixed bracket installed on the inner wall of the machine body. On the top surface of the fixed bracket, a second fixing block is installed. The inner wall of the second fixing block is rotatably connected to a second driving rod. One end of the second driving rod is installed with a second reduction motor. The outer wall of the second driving rod is provided with a blade body.

[0008] The swinging assembly includes a support frame installed on the top surface of the machine body. On the top surface of the support frame, a servo motor is installed. The output end of the servo motor is installed with a third driving rod. The bottom of the third driving rod is installed with a turntable. The bottom of the turntable is installed with an eccentric wheel. One end of the outer wall of the eccentric wheel is installed with one end of a second connecting block. The other end of the second connecting block is installed with a rotating rod at the bottom. The outer wall of the rotating rod is rotatably connected to a fixed ring. The outer wall of the lower end of the rotating rod is installed with a tail plate.

[0009] The interception assembly includes a third fixing block installed on the top surface of the machine body. On one side surface of the third fixing block, a three-phase asynchronous motor is installed. The output end of the three-phase asynchronous motor is installed with a fourth driving rod. The output end of the fourth driving rod is installed with an interception plate.

[0010] Further preferably, the floating drum is designed in a shape combining a hemisphere and a cylinder, and the material of the floating drum is expandable polystyrene.

[0017] In the present utility model, a design facilitating cleaning is adopted. The water source supplied to the high-pressure water pump usually comes from the aquaculture lotus pond. However, there are often waste materials such as floating withered lotus leaves and broken lotus stems in the lotus pond, which are likely to cause blockage of the water inlet, reduce the water inlet speed of the water pump, and thus lead to damage to the water pump. By starting the three-phase asynchronous motor, the three-phase asynchronous motor drives the intercepting plate to rotate reciprocally through the fourth driving rod. Through the rapid rotation and quick return swing of the intercepting plate, the waste materials in the lotus pond near the water inlet can be effectively intercepted and cleaned, avoiding blockage of the water inlet caused by the waste materials. At the same time, through the design of the filter screen, when the intercepting plate stops swinging, the water at the water inlet can be filtered.

[0018] In the present utility model, a design of an adjustable high-pressure nozzle is adopted. The first reduction motor can be started. The first reduction motor drives the crank to rotate through the first driving rod. Inside the mounting bracket, a rocker is installed between the cranks. Between the mounting brackets, the cranks are connected to each other through a connecting block, so as to realize the synchronous rotation of the first driving rod driving eight cranks and four rockers, driving the high-pressure nozzle to slide on the slide rail, achieving the effect of controlling the left and right swing of the high-pressure nozzle to wash the sludge, increasing the operation width while reducing the number of high-pressure nozzles, and effectively improving the working efficiency.

[0032] In this embodiment, as Figure 1 shown, the floating drum 2 is designed in the shape of a combination of a hemisphere and a cylinder, and the material of the floating drum 2 is expandable polystyrene; through this design, the device can float on the water surface by the buoyancy generated by the floating drum 2, and a sensor is fixed inside the floating drum 2. The liquid level height is detected by an AD conversion voltage signal. By controlling the amount of water inside the floating drum 2, the center of gravity position is changed to realize the left and right deflection of the whole machine, making the movement of the whole machine more flexible, and at the same time, it can avoid scratching the lotus roots.

[0033] In this embodiment, as Figure 1As shown, the baffle 4 is designed with a flat middle and upturned sides, and the baffle 4 is located behind the armrest 3; through this design, it is beneficial to collect floating lotus roots in front of the baffle 4, so as to achieve convenient, fast and orderly aggregation of lotus roots, thus contributing to the collection of lotus roots.

[0034] In this embodiment, as Figure 3 shown, the first reduction motor 610 and the crank 607 form a transmission structure through the first drive rod 609, and there are four mounting brackets 602 in total, and the inner surface of the high-pressure nozzle 605 is provided with a slider whose external dimension structure is consistent with the internal dimension structure of the slide rail 603; through this design, the first reduction motor 610 can be started, and the first reduction motor 610 drives the crank 607 to rotate through the first drive rod 609. Inside the mounting bracket 602, a rocker 606 is installed between the cranks 607. Between the mounting brackets 602, the cranks 607 are connected to each other through the first connecting block 608, so as to realize the synchronous rotation of the first drive rod 609 driving eight cranks 607 and four rockers 606, driving the high-pressure nozzle 605 to slide on the slide rail 603, achieving the effect of controlling the left and right swing of the high-pressure nozzle 605 to wash the silt, increasing the operation width while reducing the number of high-pressure nozzles 605, and effectively improving the work efficiency.

[0035] In this embodiment, as Figure 4 shown, the second reduction motor 704 and the blade body 705 form a transmission mechanism through the second drive rod 703; through this design, the second reduction motor 704 can be started, and the second reduction motor 704 drives the blade body 705 to rotate through the second drive rod 703, so as to realize the driving ability of the machine body 1.

[0036] In this embodiment, as Figure 5 shown, the servo motor 802 and the turntable 804 form a transmission mechanism through the third drive rod 803; through this design, the servo motor 802 can be started, and the servo motor 802 drives the turntable 804 to rotate through the third drive rod 803, making the eccentric wheel 805 move left or right, so that the second connecting block 806 moves left and right, and then drives the tail plate 809 to swing through the rotating rod 807. Drawing on the principle that the fish tail can generate tail fin thrust when swinging during straight swimming, the tail plate 809 can generate a powerful flapping when swinging, and then quickly flap in the opposite direction once. The first flap generates a large eddy current, and the second flap generates a completely reverse rotating eddy current. When the two eddy currents are pushed away from the fish tail and weaken each other, a powerful jet flow is formed. This jet flow can assist the whole machine to swing left and right, saving effort while achieving a larger working area and effectively improving the production efficiency.

[0037] In this embodiment, as Figure 6As shown in the figure, the three-phase asynchronous motor 902 and the intercepting plate 904 form a transmission mechanism through the fourth driving rod 903, and a filter screen is provided on the inner wall of the intercepting plate 904; through this design, the three-phase asynchronous motor 902 can be started, and the three-phase asynchronous motor 902 drives the intercepting plate 904 to rotate reciprocally through the fourth driving rod 903. Through the rapid swing of the intercepting plate 904, the lotus pond waste near the water inlet 10 can be effectively intercepted and cleaned, avoiding the blockage of the water inlet 10 caused by the waste. At the same time, through the design of the filter screen, when the intercepting plate 904 stops swinging, the water at the water inlet 10 can be filtered.

[0038] The usage method and advantages of the present utility model: The intercepting device for the water inlet of the lotus root digging machine, when in use, the working process is as follows:

[0039] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, first hold the handrail 3 and start the second reduction motor 704. The second reduction motor 704 drives the blade body 705 to rotate through the second drive rod 703, so as to realize the driving ability of the body 1, drive the body 1 to move, and the device can float on the water surface by the buoyancy generated by the pontoon 2. A sensor is fixed inside the pontoon 2, and the liquid level height is detected by the AD conversion voltage signal. By controlling the amount of water inside the pontoon 2, the center of gravity position is changed to realize the left and right deflection of the whole machine, making the movement of the whole machine more flexible. And the servo motor 802 can be started. The servo motor 802 drives the turntable 804 to rotate through the third drive rod 803, so that the eccentric wheel 805 moves left or right, thereby making the second connecting block 806 move left and right, and then driving the tail plate 809 to swing through the rotating rod 807. Drawing on the principle that the fish tail can generate tail fin thrust when swinging during straight swimming, the tail plate 809 can generate a powerful flapping when swinging, and then quickly flap in the opposite direction once. The first flapping generates a large eddy current, and the second flapping generates a completely reverse-rotating eddy current. When the two eddy currents push away from the fish tail and weaken each other, a powerful jet is formed, and this jet can assist the whole machine to swing left and right. While saving effort, it can achieve a larger working area. Then start the high-pressure water pump 11. The high-pressure water pump 11 is connected to the high-pressure nozzle 605 through the water pipe 12. The first reduction motor 610 can be started. The first reduction motor 610 drives the crank 607 to rotate through the first drive rod 609. And inside the mounting bracket 602, a rocker 606 is installed between the cranks 607. Between the mounting brackets 602, the cranks 607 are connected to each other through the first connecting block 608, so as to realize that the first drive rod 609 drives eight cranks 607 and four rockers 606 to rotate synchronously, driving the high-pressure nozzle 605 to slide on the slide rail 603, so as to control the left and right swing of the high-pressure nozzle 605 to wash the silt. After the silt covering the surface of the lotus root is fully washed, the lotus root floats to the water surface, and the floating lotus root can be collected in front of the baffle 4.

[0040] The above shows and describes the basic principle, main features and advantages of the present invention. Technical staff in this industry should understand that the present invention is not limited by the above embodiments.
