Description

Technical Field

[0001] This invention relates to the field of sweet potato harvesting technology, and in particular to a fully automatic sweet potato harvester for sandy soil. Background Technology

[0002] With the development of society, the pace of life has accelerated, and labor costs have increased. The automation of agriculture has gradually become a trend. Sweet potatoes are a common crop in my country. Due to their advantages such as low investment, high yield per mu, considerable income, and strong adaptability, many farmers are eager to plant them. However, with the increase in the planting area of ​​sweet potatoes, the existing methods of harvesting sweet potatoes can no longer meet the needs of farmers. Specifically, this is reflected in the following aspects: (1) The increase in planting area has led to a longer harvesting cycle for sweet potatoes, resulting in a shortage of supply; (2) The sweet potato harvesters currently available on the market can only turn the sweet potatoes to the ground, and manual picking is still required, which is labor-intensive, time-consuming, and labor-intensive; (3) In order to complete the harvesting work, farmers need to hire workers, which is costly and greatly reduces the net income of farmers, and the quality of sweet potato harvest cannot be guaranteed. Summary of the Invention

[0003] In order to overcome the shortcomings of the above-mentioned technologies, the purpose of this invention is to provide a fully automatic sweet potato harvesting device. Using this product, the entire sweet potato harvesting process is fully automated, saving a lot of manpower, reducing harvesting costs, and achieving high work efficiency.

[0004] In order to achieve the above objectives, the technical solution of the present invention is as follows.

[0005] A fully automatic sweet potato harvester for sandy soil includes a tractor and a suspension frame installed at the rear of the tractor. The suspension frame is characterized by having a vibrating soil-feeding toothed plate, a soil-leaking conveyor belt, a limit wheel, and a drive device.

[0006] The suspension frame includes two longitudinally arranged baffles and an inverted "V" shaped connecting frame; the two baffles are connected by the connecting frame; a first transverse rotating shaft is installed between the front ends of the two baffles; a diagonal rod is fitted on the side of the first transverse rotating shaft close to each baffle and near the other baffle; a connecting plate is connected between the top ends of the two diagonal rods; and a vibrating toothed plate is installed between the top ends of the diagonal rods.

[0007] A second transverse shaft is located behind the first transverse shaft between the two baffles, and a third transverse shaft is installed between the bottom rear ends of the two baffles. The soil-leaking conveyor belt is fitted onto the radial outer circumferential surfaces of the second and third transverse shafts. The top surface of the second transverse shaft is lower than the top surface of the third transverse shaft.

[0008] The third transverse shaft has drive wheels at both ends.

[0009] The driving device includes a fourth horizontal rotating shaft. Brackets are provided above the rear ends of the two baffles respectively. The fourth horizontal rotating shaft is arranged between the two brackets. A gearbox is provided in the middle of the fourth horizontal rotating shaft. The front end of the gearbox is connected to a universal joint through a first transmission rod, and the universal joint is connected to the power device of the tractor through a second transmission rod. Above the center of each third horizontal rotating shaft drive wheel on the fourth horizontal rotating shaft, a first transmission wheel is provided, and each third horizontal rotating shaft drive wheel is connected to the first transmission wheel directly above it through a transmission chain.

[0010] On both sides of the gearbox on the fourth horizontal rotating shaft, an eccentric wheel is installed respectively, and each eccentric wheel is connected to a connecting plate through a connecting rod.

[0011] On the side of each baffle away from the other baffle, a height-adjustable limit wheel is provided.

[0012] The beneficial effects of the present invention are as follows: As the tractor moves forward and the fourth horizontal rotating shaft rotates, the eccentric wheel drives the connecting rod to move, and the vibrating soil-entering tooth plate enters the soil, and the sweet potatoes are dug out from the sand, and the sand is separated from the sweet potatoes. The sweet potatoes are sent to the soil-leaking conveyor belt, and the sweet potatoes fall to the ground from the rear end of the soil-leaking conveyor belt. When the sweet potatoes are transported from low to high, the sand adhering to the surface of the sweet potatoes can also fall to the ground surface. The limit wheel is provided to finely adjust the soil-entering depth. The structure of the present invention is simple. The fourth horizontal rotating shaft transmits all the power for sweet potato harvesting. The transmission route is simple, the volume is small, it can be removed from the tractor when idle, does not occupy space, and has a high degree of automation.

[0043] The invention will now be further described with reference to the accompanying drawings.

[0044] Example 1. As... Figure 1-10 As shown, a fully automatic sweet potato harvester for sandy soil includes a tractor 1, a suspension frame 2 installed at the rear of the tractor 1, a vibrating soil-feeding toothed plate 3, a soil-leaking conveyor belt 4, a limit wheel 5, and a drive device.

[0045] The suspension frame 2 includes two longitudinally arranged baffles 21 and an inverted "V"-shaped connecting frame 22; the two baffles 21 are connected by the connecting frame 22; a first transverse rotating shaft 25 is installed between the front ends of the two baffles 21, and a diagonal rod 23 is fitted on the side of the first transverse rotating shaft 25 close to each baffle 21 near the other baffle 21; a connecting plate 24 is connected between the top ends of the two diagonal rods 23; and a vibrating soil-penetrating toothed plate 3 is installed between the top ends of the diagonal rods 23.

[0046] A second transverse shaft 26 is provided on the rear side of the first transverse shaft 25 between the two baffles 21, and a third transverse shaft 27 is installed between the bottom of the rear ends of the two baffles 21. The soil conveyor belt 4 is fitted onto the radial outer circumferential surface of the second transverse shaft 26 and the third transverse shaft 27. The top surface of the second transverse shaft 26 is lower than the top surface of the third transverse shaft 27.

[0047] The third transverse shaft 27 has third transverse shaft drive wheels 28 at both ends.

[0048] The drive unit includes a fourth transverse rotating shaft 6. Each of the two baffles 21 has a bracket 61 above its rear end. The fourth transverse rotating shaft 6 is positioned between the two brackets 61. A gearbox 62 is located in the middle of the fourth transverse rotating shaft 6. The front end of the gearbox 62 is connected to a universal joint 64 via a first transmission rod 63. The universal joint 64 is connected to the power unit of the tractor 1 via a second transmission rod 65. A first transmission wheel 66 is located directly above each of the third transverse rotating shaft drive wheels 28 on the fourth transverse rotating shaft 6. Each of the third transverse rotating shaft drive wheels 28 is connected to the first transmission wheel 66 directly above it via a transmission chain 67.

[0049] An eccentric wheel 68 is installed on each side of the gearbox 62 on the fourth transverse rotating shaft 6. Each eccentric wheel 68 is connected to the connecting plate 24 via the connecting rod 69.

[0050] Each baffle 21 has a height-adjustable limiting wheel 5 on the side away from the other baffle 21.

[0051] As the tractor 1 moves forward, the fourth transverse rotating shaft 6 rotates, causing the eccentric wheel 68 to drive the connecting rod 69 to move. This vibrates the soil-penetrating toothed plate 3, digging the sweet potato out of the sand and separating it from the soil. The sweet potato is then conveyed to the soil-leaking conveyor belt 4, falling to the ground from its rear end. During this upward transport, any sand adhering to the sweet potato's surface falls to the ground. A limit wheel 5 is provided for fine-tuning the soil penetration depth. This invention features a simple structure, convenient power transmission route, small size, and can be removed from the tractor when not in use, saving space and offering a high degree of automation.

[0052] The vibratory toothed plate 3 includes a transversely arranged vibratory toothed plate body 31, and a number of soil entry teeth 32 are longitudinally arranged at the front end of the vibratory toothed plate body 31. The angle between each soil entry tooth 32 and the ground is 20-45 degrees.

[0053] In the middle of the side of each baffle 21 away from the other baffle 21, there is an insertion tube 29 with a "mouth" - shaped horizontal cross - section. On each insertion tube 29, a limiting wheel fork 51 is vertically installed, and a limiting wheel 5 is installed at the bottom end of the limiting wheel fork 51.

Each insertion tube 29 and the limiting wheel fork 51 are connected by a pin 53 inserted into an insertion tube hole 52 and an insertion hole 210. Through this technical solution, the entry angle of the vibrating soil - entering tooth plate 3 can be adjusted according to the size of the sweet potatoes to be harvested.

[0055] The top end and the two bottom ends of the connecting frame 22 are respectively connected to the rear end of the tractor 1 through connecting hinges 211.

[0056] Each support 61 is connected to the top end of the connecting frame 22 through an inclined pull rod 212.

[0057] The soil - leakage conveyor belt 4 includes a number of horizontally arranged connecting rods 41, and two annular belts 42 arranged symmetrically on the left and right. Each annular belt 42 is sleeved on the outer peripheral surface of the second horizontal rotating shaft 26 and the third horizontal rotating shaft 27; both ends of each connecting rod 41 are respectively connected to the annular belt 42.

[0058] Embodiment 2. As Figure 8-10 shown, the difference between this embodiment and Embodiment 1 is that: between each eccentric wheel 68 and the first transmission wheel 66 closest to it on the fourth horizontal rotating shaft 6, there is a second transmission wheel 610; on the top end and the bottom end of the front side of each baffle 21, there is a longitudinal plate 7, and between the longitudinal plates 7 on the top end and the bottom end of the front side of each baffle 21, a rotating rod 71 parallel to the front side of the baffle 21 is installed, and a third transmission wheel 72 is provided at the top end of each rotating rod 71; each third transmission wheel 72 and the second transmission wheel 610 closest to it are connected by a transmission belt 73.
