Description

Technical Field

[0001] The invention relates to the technical field of agricultural tools, in particular to a yam harvester. Background Art

[0002] As my country's agricultural modernization accelerates, agricultural production methods are undergoing profound changes. Among them, as an economic crop with high economic value and a wide planting area, the problems faced by yam in the planting and harvesting process are becoming increasingly prominent. For a long time, the harvesting of yam has mainly relied on traditional manual digging methods, which is not only labor-intensive and inefficient, but also easy to cause damage to the yam, affecting its quality and market value.

[0003] In my country, yam cultivation has a long history and a vast planting area, mainly concentrated in Henan, Shandong, Hebei, Shanxi and other provinces. The climate and soil conditions in these areas are suitable for yam growth, which has led to the booming yam industry in these places. However, the traditional way of harvesting yam often requires farmers to bend over and dig the soil. After working for a long time, not only is the body tired, but it is also easy to cause various occupational diseases. With the continuous growth of market demand and the advancement of agricultural modernization, the traditional way of harvesting yam can no longer meet the needs of modern agricultural production.

[0004] For example, a Chinese invention patent with announcement number CN108464100A discloses a yam harvesting robot, including a frame, connecting shafts are respectively arranged in parallel at the front and rear of the frame, and walking systems are arranged on both sides of the frame; a harvesting frame is arranged in the middle of the frame, the upper part of the harvesting frame is a triangle, and two support arms are hingedly arranged at the front end of the triangle, and plow pan supports are respectively slidably installed at the lower part of the support arms, and a mounting frame is arranged on the outer side of each plow pan support, and an excavation and lifting hydraulic cylinder is arranged between the support arm and the plow pan support on the same side, and a driving frame is also hingedly installed at the middle position of the upper part of the support arm, and the other end of the driving frame is respectively hingedly installed on both sides of the top head, and the middle part of the top head is connected to the piston rod end of the excavation and gathering hydraulic cylinder, and the cylinder body end of the excavation and gathering hydraulic cylinder is hingedly installed at the front end of the harvesting frame.

[0005] The above solution has the following shortcomings in actual use:

[0006] This solution adopts a plow disk that can be flexibly adjusted at multiple angles to achieve the function of deep digging of the soil. It adopts a mud discharge device to achieve the function of further cleaning the soil on the surface of the yam after deep digging of the soil. However, when in use, the yam cannot be recovered. Two plow disks are used to dig the soil at the same time. First, the loosening effect of the soil is not good.

DETAILED DESCRIPTION

[0031] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0033] like Figure 1As shown, a yam harvester includes: a trolley body 100, a loosening unit 300, a harvesting unit 400 and a conveying unit 500. The trolley body 100 is provided with a power supply module 200 for supplying power to the loosening unit 300, the harvesting unit 400 and the conveying unit 500. The loosening unit 300 is arranged at the front side of the trolley body 100 for loosening the soil. The loosening unit 300 includes two sets of symmetrically arranged chain drive systems, and there is a certain distance between the two sets of chain drive systems to avoid damage to the yam. The harvesting unit 400 is arranged between the loosening unit 300 and the trolley body 100. 00, it is used to harvest the yam in the soil after loosening the soil. The conveying unit 500 is set on the trolley body 100 to convey the harvested yam. When harvesting the yam, the height and angle of the loosening unit 300 are adjusted by the harvesting unit 400, so that the loosening unit 300 can be inserted into the soil, loosen the soil and lift the yam in the soil upward. At the same time, the harvesting unit 400 can simulate the action of shoveling the ground to shovel the yam in the soil and send it into the conveying unit 500. The conveying unit 500 cleans the soil attached to the yam and transports it to the designated collection box.

[0034] like Figure 4 and Figure 5 As shown, the chain drive system includes a frame 301, and the two ends of the frame 301 are connected with a chain 304 through two sprockets. The top of the frame 301 is provided with a driving shaft 303 connected with the sprocket and an actuator 302 for driving the driving shaft 303 to rotate. The actuator 302 uses a motor as a driving force. Because the motor has high efficiency and reliability, it can provide stable and strong power output. The use of the motor also makes the operation of the harvester easier. The loosening operation can be easily achieved by controlling the start and stop and speed of the motor. The motor torque is transmitted to the driving shaft 303 through the bevel gear transmission to start the chain 304 to start moving. The chain 304 is provided with a plurality of blades. The blade connecting plate 305 is provided with a plurality of blades 306, and a connecting seat 307 is provided on one side of the frame 301, wherein the chain 304 is made of high-quality materials to increase its durability and wear resistance, and the material selection and heat treatment process of the chain 304 are strictly quality controlled to ensure that the chain can withstand high-intensity vibration and friction during use and extend its service life, wherein the actuator 302 is a motor with high efficiency and reliability, and can provide stable and strong power output, and the motor is used to drive the chain 304, the blade connecting plate 305 and the blade 306 to move, so as to cut the soil and achieve the purpose of loosening the soil.

[0035] like Figure 2 and Figure 3As shown, the harvesting unit 400 includes two mounting seats 401, a driving arm 402 is provided on one side of the mounting seats 401, a motor group for driving the driving arm 402 to rotate is provided on the mounting seats 401, a push rod 403 is provided at the end of the driving arm 402, a guide seat 404 is sleeved on the push rod 403, the guide seats 404 are respectively connected to the mounting seats 401, the ends of the push rod 403 are slidably connected with a connecting plate 406 through a slide 405, a vibrating shovel mounting seat 407 is provided at the bottom of the two connecting plates 406, and a vibrating shovel 408 is provided on the vibrating shovel mounting seat 407, wherein the driving arm 402 is driven to rotate by the motor group, and the push rod 403 is guided by the guide seat 404 to realize the reciprocating motion, and the vibrating shovel 408 is made to reciprocate under the action of the slide 405, simulating the action of shoveling the ground, so as to collect the middle yam and soil.

[0036] Furthermore, the top of the connecting plate 406 is rotatably connected to a connecting arm 409, and the connecting arm 409 is rotatably connected to the connecting seat 307 through a rotating shaft 410. With the cooperation of the above structure, the vibrating shovel 408 can move synchronously with the up and down movement of the chain drive system. A fixed seat 411 is provided on the upper surface of the trolley body 100, and an electric push rod 412 is provided on the fixed seat 411. A bearing seat 413 is provided at the output end of the electric push rod 412. The bearing seat 413 is rotatably connected to the two sets of chain drive systems through a rotating shaft. The height of the chain drive system is adjusted by the electric push rod 412, which can avoid the phenomenon of cutting soil during walking in a non-working state. The front side of the fixed seat 411 is rotatably connected to an electric push rod 414, and the output end of the electric push rod 414 is rotatably connected to the two sets of chain drive systems through a connecting shaft 415. The electric push rod 414 can adjust the angle of the chain drive system, thereby realizing the adjustment of the soil cutting angle and improving the utilization rate of cutting soil.

[0037] like Figure 6 and Figure 7As shown, the conveying unit 500 includes two support frames 501 arranged on the lower surface of the trolley body 100, and a conveyor 1 502 is rotatably connected between the two support frames 501 through a bearing, and the input side of the conveyor 1 502 is rotatably connected to two connecting members 503, and the ends of the connecting members 503 are slidably connected to a slide rail 504 through a slider, and the ends of the connecting members 503 are rotatably connected to the slider, and a conveyor 2 505 is arranged between the two slide rails 504. With the cooperation of the above structure, the extension and extension of the conveyor 1 502 and the conveyor 2 505 can be realized. The conveyor 1 502 and the conveyor 2 505 have a contraction function, so that the conveyor 2 505 can follow the movement of the vibrating shovel 408, ensuring that when the vibrating shovel 408 scoops up the yam, the conveyor 1 502 and the conveyor 2 505 can transport the yam in time. The input side of the conveyor 2 505 is rotatably connected with the output side of the vibrating shovel 408 through a rotating shaft. It should be noted that the conveyor 1 502 and the conveyor 2 505 both include a conveyor frame, a conveyor belt, a transmission roller and a motor. The transmission roller is rotated by controlling the motor to realize the movement of the conveyor belt and complete the transportation of the yam.

[0038] Furthermore, a conveyor belt 514 is arranged at the rear side of the upper surface of the trolley body 100, and the conveyor belt 514 is arranged at an angle. Two transmission rollers 516 are sleeved inside the conveyor belt 514. The transmission roller 516 located at a high position is connected to the trolley body 100 through a bearing seat 517. An actuator 509 for driving the transmission roller 516 is arranged on the upper surface of the trolley body 100. The ends of the transmission roller 516 located at a low position are rotatably connected to two frames 515 through bearings. The frames 515 are connected to the lower surface of the trolley body 100. In actual use, baffles are arranged on both sides of the conveyor belt 514 to In order to avoid the yam falling when being transported, the material of the conveyor belt 514 is wear-resistant and corrosion-resistant to adapt to different soil and environmental conditions. The width of the conveyor belt 514 is sufficient to accommodate yams of different sizes, and the smooth surface reduces the friction and damage of the yams during transportation. The running speed of the conveyor belt can be adjusted to ensure that the yams can be transported smoothly while avoiding collision and rolling of the yams caused by excessive speed. The inclination angle of the conveyor belt 514 can also be adjusted according to actual needs to adapt to different harvesting conditions and yam planting depths.

[0039] Furthermore, two groups of mounting frames 506 are provided on the lower surface of the trolley body 100, and rollers 507 are provided in the two groups of mounting frames 506. A plurality of transmission wheels 508 are rotatably connected to the mounting frames 506 through a rotating shaft. Two annular slide rails 510 corresponding to the transmission wheels 508 are provided on the outer circumference of the roller 507. A plurality of sieve holes 511 are provided on the roller 507, and a plurality of spiral plates 512 are provided on the inner circumference of the roller 507. The outlet side of the roller 507 is located above the conveyor belt 514. In the process of harvesting yam, as the trolley body 100 moves, the lower part of the roller 507 will also perform the process of shoveling soil, and at the same time, under the action of the internal spiral plate 512, the yam can be harvested. The drum 507 is caused to rotate, and the sieve holes 511 on the drum 507 are large enough to allow soil particles to pass smoothly, but small enough to prevent the yams from being damaged during the excavation process. The soil entering the drum 507 can be discharged through the sieve holes 511, and the yams fall onto the conveyor belt 514 under the push of the soil and subsequent yams. In actual use, an actuator 509 for driving the drum 507 to rotate can be provided on one of the mounting frames 506 as needed, so as to adjust its rotation speed and ensure that the yams are excavated under the most suitable conditions. This flexibility can adapt to different soil types and yam planting depths, thereby achieving efficient and lossless harvesting.

[0040] The working process of this embodiment is as follows: when harvesting yam, the height of the loosening unit 300 is adjusted by controlling the push rod 1 412, and the height of the vibrating shovel 408 changes accordingly. Then, the angle of the loosening unit 300 is adjusted by controlling the electric push rod 2 414, and the loosening unit 300 is controlled to cut and loosen the soil. The vibrating shovel 408 and the roller 507 can scoop up the turned yam, and the yam on the vibrating shovel 408 is transported to the roller 507 under the transportation of the conveyor 1 502 and the conveyor 2 505. As the roller 507 rotates, the soil on the yam can be discharged through the sieve hole 511, and the yam continues to move to the conveying unit 500, and the conveying unit 500 conveys the yam.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
