Embodiment 1

[0038] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 Shown:

[0039] This potato harvester comprises a body, the two sides of the body are provided with ground wheels 17, the front end of the body is provided with a traction device and an excavating device, and the rear end of the body is provided with a collection device, which is connected by a conveying device between the collection device and the excavation device.

[0040] The traction device includes a traction frame fixed on the machine body and a three-point suspension device installed on the traction frame.

[0041] Excavator comprises the shovel frame 19 that is installed on body front end and the digging shovel 18 that is installed on the shovel frame 19, and support 21 is installed symmetrically on the both sides of shovel frame, and soil cutting disc 20 is symmetrically installed on support 21, and soil cutting disc 20 is connected on the bracket 21 by the shaft 22.

[0042]The conveying ...

Embodiment 2

[0048] Such as Figure 6 and Figure 7 Shown:

[0049] Different from Embodiment 1, the switch device of the potato divider is a baffle plate 7 installed on the collection box, and the working process of the directional stacking device is as follows: the switch control device is a stroke control device, and the stroke control device includes a cam 11. The rotating shaft is connected to the ground wheel 12 of the potato harvester through the transmission device; the periphery of the cam 11 is lapped to the switch system, and the switch system is connected to the switch device of the potato divider. Transmission device comprises a transmission shaft 13 that bevel gear is installed, and transmission shaft 13 is connected to the ground wheel 12 of potato harvester through sprocket transmission device, and the output shaft of bevel gear box is equipped with cam 11; Switch system comprises connecting rod 10, connects Bar 10 is provided with slide block 9, and slide block 9 can sli...

Embodiment 3

[0052] Such as Figure 8 Shown:

[0053] Different from Embodiment 1 and Embodiment 2, the switch device of the potato divider is a baffle plate 7 installed on the collection box, and the working process of the directional stacking device is as follows: the switch control device is a weight control device, and the weight control device includes a counterweight Block 14, fixed shaft 15 and connecting rod 16, fixed connection between counterweight 14 and baffle plate 7, be connected to connecting rod 16 through fixed shaft 15, counterweight 14 and baffle plate 7 can rotate around fixed shaft 15, connect One end of the rod 16 is connected to the fixed shaft 15 , and the other end of the connecting rod 16 is installed on the collection box 1 .

[0054] The counterweight control device is based on the principle of leverage. Since the counterweight 14 has a certain weight, when the potato pieces in the temporary potato collection area reach a certain weight, the pressure of the pot...

Abstract

The invention provides a potato harvesting machine. The potato harvesting machine comprises a machine body, wherein ground wheels are arranged on the two sides of the machine body; a dragging device and a digging device are arranged at the front end of the machine body and a collection device is arranged at the rear end of the machine body; the collection device and the digging device are connected by a conveying device. The collection device is arranged on the rear part of the harvesting machine and comprises a collection box; the collection box is provided with a potato inlet and a potato outlet; the potato inlet is connected with the conveying device and a potato collection cavity is arranged between the potato inlet and the potato outlet; an oriented collection device is arranged in the potato collection cavity; the oriented collection device comprises a potato sorting device and a potato sorting device switching-on / off device; the potato sorting device comprises a middle shaft and a potato sorting device arranged around the middle shaft; the potato sorting device comprises a plurality of potato sorting plates which are uniformly arranged around the circumference of the middle shaft; the potato sorting device is mounted in the potato collection cavity by the middle shaft and can rotate around the middle shaft; the potato sorting device switching device is a baffle mounted on the collection box; in the rotation process of the potato sorting device, the potato sorting plates are overlapped with the baffle and the baffle is connected with a switching-on / off control device.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a potato harvester used in potato harvesting. Background technique [0002] Potato is the fourth largest crop in my country, second only to wheat, rice, and corn. It is planted all over the country, and the planting area is relatively wide, and it is still increasing year by year at a rapid rate. The research of the World Potato Center shows that the demand for potatoes worldwide will increase by about 20% by 2020, and the demand for potatoes in developing countries will also be higher at that time. From the analysis of international and domestic situations, we can know that the production of potatoes Start to scale and standardize. [0003] Potato production efficiency in my country is low, and the yield per mu is only equivalent to about 40% of that in developed countries such as Europe and the United States. Potatoes are harvested mai...
