Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a jet-type lotus root harvester with a collecting mechanism. Background Art

[0002] Lotus roots generally grow in a lying position under the mud layer, with a small angle to the water surface. Their growth is irregular and lotus roots are mostly harvested in autumn and winter.

[0003] According to publication number CN216820743U, an efficient lotus root harvesting device is provided with a water pump, a water pipe, a water tank, a drain pipe and a high-pressure nozzle. The water pump draws water from the pond into the water pipe and pressurizes it, and transports the pressurized water to the inside of the water tank through a connecting pipe. The water tank plays a diversion role. A plurality of drain pipes are fixedly connected to the bottom of the inner wall thereof. One end of the drain pipe is connected to the high-pressure nozzle. The high-pressure nozzle sprays water into the bottom of the pond to flush away the silt around the lotus root and make the lotus root float to the surface of the water, thereby realizing the harvesting of the lotus root. The overall operation is simple and the operation requirements are not difficult. Compared with manual digging, the breakage rate is lower and the collection efficiency is higher.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] The collecting mechanism 2 includes a rotating grab 21 and a conveyor belt 22. The rotating grab 21 and the conveyor belt 22 are both installed between the floating plates 1. The rotating grab 21 is rotatably connected and is driven to rotate by a motor. The lotus roots on the water surface are grabbed by the rotation of the rotating grab 21. One end of the conveyor belt 22 is raised by a bracket so that the tail end and the front end are inclined and installed between the floating plates 1. Multiple rows of tooth columns 221 are equidistantly installed on the conveyor belt 22. The conveyor belt 22 transports the lotus roots under the action of the tooth columns 221. A collecting box 3 is provided at the tail end of the conveyor belt 22. The lotus roots are collected by the tooth columns 22 of the conveyor belt 22. 1 is transported to the collection box 3 for temporary storage, and the collection box 3 is detachably installed (bolt fixed or directly erected) at the tail end of the floating plate 1. A plurality of drainage holes 31 are opened around the collection box 3. The water carried by the lotus roots in the collection box 3 is discharged through the drainage holes 31 to prevent the collection box 3 from being too heavy and causing the floating plate 1 to tilt. When the collection box 3 is full, the lotus roots inside it can be transferred by disassembling the collection box 3. The front end of the floating plate 1 is fixed with a mounting plate 4 by bolts, and a flushing mechanism 5 is erected on the top of the mounting plate 4 and fixed with bolts. The lotus roots growing under the mud layer are flushed and dug out by the flushing mechanism 5.

[0050] By moving the floating plate 1, the flushing mechanism 5 on the front mounting plate 4 of the floating plate 1 flushes and digs the lotus roots hidden under the mud layer, so that the lotus roots are freed from the soil and float on the water surface. Then, the lotus roots on the water surface are grabbed by the rotating grab 21 and put on the conveyor belt 22. When the conveyor belt 22 is started, the lotus roots are transferred to the collection box 3 through the gear column 221 for temporary storage. The water on the conveyor belt 22 and the lotus root belt is discharged through the drain hole 31.

[0051] By moving the float plate 1, the collecting mechanism 2 collects the lotus roots floating on the water surface, thereby avoiding the increase and consumption of manpower and material resources caused by manual identification and selection when the lotus roots are scattered on the water surface.

[0052] A step further, such as Figure 1 、 Figure 3and Figure 4 As shown: the flushing mechanism 5 includes an engine 51 placed on the top of the mounting plate 4, and sewage pumps 52 are installed on both sides of the engine 51. The engine 51 and the sewage pumps 52 on both sides of the engine 51 are fixed to the mounting plate 4 by bolts. The starting end of the sewage pump 52 is connected to the output end of the engine 51 through a transmission belt assembly. The operation of the sewage pump 52 is driven by the transmission belt assembly. By using the sewage pump 52, the situation that excessive mud and debris on the water surface are easily blocked during suction is avoided. The output end of the sewage pump 52 is connected to a water distribution pipe 53. The engine 51 The output end is connected to the swing flushing assembly 54 through a reducer transmission, the water distribution pipe 53 is fixed to the top of the mounting plate 4 through a mounting flange 531, and the mounting flange 531 is fixed to the top of the mounting plate 4 by bolts, thereby achieving the fixation of the water distribution pipe 53, and water delivery pipes 532 are equidistantly arranged on the water distribution pipe 53. The swing flushing assembly 54 includes a connecting rod 541, and eccentric wheels 542 are installed at both ends of the connecting rod 541. A driving rod 543 is fixed at the center of the eccentric wheel 542 at one end. The driving rod 543 is connected to the output end of the engine 51 through a reducer transmission.

[0053] Two slide bars 545 are provided on the connecting rod 541. Both slide bars 545 are located on the side of the eccentric wheel 542. Both slide bars 545 are slidably connected to a slider 546. Both sliders 546 are slidably connected to an upper cross bar 547. Both upper cross bars 547 are installed with multiple groups of nozzle mounting tubes 548. Both multiple groups of nozzle mounting tubes 548 are installed with lower cross bars 549 on the side away from the upper cross bar 547. Both lower cross bars 549 are connected to the floating plate 1 through a connecting rod. The output ends of the two multiple groups of nozzle mounting tubes 548 are installed with nozzles. The nozzles of the multiple groups of nozzle mounting tubes 548 in the upper cross bar 547 of one group of sliders 546 and the lower cross bar 549 are conical round hole nozzles. The first row uses conical round hole nozzles. The hole nozzle is in the front, with strong penetrating power, and is used for cutting and crushing soil. The nozzles of the multiple nozzle mounting pipes 548 in the upper cross bar 547 and the lower cross bar 549 of the other set of sliders 546 are flat nozzle nozzles. The second row uses flat nozzle nozzles in the back, which are used to further crush the soil and clean the silt on the surface of the lotus root to ensure the cleanliness of the cleaning. The input ends of the two multiple nozzle mounting pipes 548 are connected to the water pipe 532 through a water pipe. The sewage pump 52 draws water from the water source on the water surface and transports it to the multiple nozzle mounting pipes 548 through the water pipe 532 on the water distribution pipe 53. The water is sprayed through the nozzles on the multiple nozzle mounting pipes 548, thereby flushing and excavating the lotus roots hidden under the mud layer, so that the lotus roots are freed from the constraints of the soil and float on the water surface;

[0054] When the engine 51 rotates, it drives the driving rod 543 to rotate, and the driving rod 543 drives the eccentric wheel 542 at one end of the connecting rod 541 to rotate, thereby driving the eccentric wheel 542 at the other end of the connecting rod 541 to rotate at the same time. During the rotation, the two sliding rods 545 slide up and down in the slider 546 respectively, and the lower cross bar 549 is fixed to the floating plate 1 through the connecting rod to remain stationary. The sliding rod 545 drives the slider 546 to swing left and right on the upper cross bar 547 under the characteristics of the eccentric wheel 542, thereby driving the multiple groups of nozzle mounting pipes 548 to swing left and right reciprocating motion. At the same time, the water source extracted by the sewage pump 52 is transmitted to the multiple groups of nozzle mounting pipes 548 through the water delivery pipe 532 on the water distribution pipe 53, and finally from The water is sprayed from the nozzles of the multiple groups of nozzle mounting tubes 548. The nozzles on the front row of the multiple groups of nozzle mounting tubes 548 are conical round hole nozzles. The conical round hole nozzles spray in a straight line in the front and have strong penetration, which can ensure the flushing of the soil and prevent the lotus roots from not being flushed and dug out due to inadequate flushing. The nozzles on the back row of the multiple groups of nozzle mounting tubes 548 are flat-mouth nozzles. The water source of the flat-mouth nozzles sprays in a fan shape, which can flush and clean the lotus roots floating on the water surface on a large scale. The lotus roots are flushed, dug and cleaned by the left and right swinging jets of the two groups of nozzle mounting tubes 548, thereby achieving full coverage within the operating width and ensuring the cleanliness of the lotus roots, avoiding the consumption of manpower and material resources caused by multiple cleanings.

[0055] Among them, the multiple groups of nozzle mounting tubes 548 on the upper cross bar 547 and the lower cross bar 549 in the two sliders 546 are arranged in an alternating manner, and the nozzles on the two groups of nozzle mounting tubes 548 are alternately reciprocated, thereby improving the lotus root harvesting rate and cleaning rate.

[0056] A step further, such as Figure 1 As shown; a pushing handrail 6 is provided at the tail end of the float 1, and the float 1 is pushed to move on the water surface by pushing the handrail 6, thereby avoiding problems such as waist discomfort caused by the operator's frequent bending over.

[0057] Among them, the above-mentioned electrical equipment are all waterproofed.

[0061] When the engine 51 rotates, it drives the sewage pump 52 to start, and the sewage pump 52 draws water from the water source on the water surface and delivers it to the multiple groups of nozzle installation pipes 548 through the water delivery pipe 532 on the water distribution pipe 53;

[0062] At the same time, it drives the driving rod 543 to rotate, and the driving rod 543 drives the eccentric wheel 542 at one end of the connecting rod 541 to rotate, thereby driving the eccentric wheel 542 at the other end of the connecting rod 541 to rotate at the same time. During the rotation, the two sliding rods 545 slide up and down in the slider 546 respectively, and the lower cross bar 549 is fixed to the floating plate 1 through the connecting rod to remain stationary. The sliding rod 545 drives the slider 546 to swing left and right on the upper cross bar 547 under the characteristics of the eccentric wheel 542, thereby driving the multiple groups of nozzle mounting pipes 548 to swing back and forth left and right. At the same time, the water source extracted by the sewage pump 52 is passed through the water distribution pipe 53. The water is transmitted through the water pipe 532 to the multiple groups of nozzle mounting pipes 548, and finally sprayed out from the nozzles of the multiple groups of nozzle mounting pipes 548 (the nozzles on the multiple groups of nozzle mounting pipes 548 in the front row are conical round hole nozzles. The conical round hole nozzles spray in a straight line in the front and have strong penetration, which can ensure the flushing of the soil and prevent the lotus roots from not being flushed and dug out due to insufficient flushing. The nozzles on the multiple groups of nozzle mounting pipes 548 in the back row are flat nozzle nozzles. The water source of the flat nozzle nozzles sprays in a fan shape, which can flush and clean the lotus roots floating on the water surface in a large range, so that the lotus roots are freed from the constraints of the soil and float on the water surface);
