Problems solved by technology

[0007] The prior art also provides a seed potato cutting machine. This invention realizes the integration of feeding, dicing, and spraying, and can mechanized convey and cut potatoes, which improves work efficiency, but fails to realize multi-stage potato cutting. Screening The potatoes are separated, screened and cut into pieces according to different quality grades, which cannot guarantee the nutritional content of the cut potato and the germination rate of the cut potato.
[0008] The prior art also provides a potato sorting device, which can sort potatoes according to the size of the potatoes, and can screen the potatoes on different conveyor belts for transport and sorting, but the machine structure is complex and bulky and the feeding Screening cannot be completed in an efficient and orderly manner, which affects the operation of subsequent dicing and other processes and reduces work efficiency
[0009] The prior art provides a seed potato gradi

Embodiment 1

[0058] Attached below Figure 1-Figure 17 The present invention is described in detail, specifically, the structure is as follows:

[0059] This embodiment provides a multi-stage screening limit feeding device, such as Figure 1-Figure 5 As shown, it includes the limit track I-01, the bearing plate I-02, the driving device, and the limit mechanism. The bearing plate I-02 is installed under the head end of the limit track I-01. 02 connected; the limit mechanism is fixed on the side of the drop opening at the end of the limit track I-01.

[0060] Specifically, the limiting track I-01 includes an outer baffle I-0101, an inner baffle I-0102, a first sorting track I-0105, a second sorting track I-0106, a first ramp I- 0111, the second ramp Ⅰ-0110, such as Figure 4 and Figure 8 As shown, the outer baffle I-0101 includes a first arc portion and a first straight line that are integrally connected, and the inner baffle I-0102 includes a second arc portion and a second straight li...

Embodiment 2

[0077] This embodiment provides a multi-stage screening limit feeding device for sorting potatoes, specifically, such as Figure 18-Figure 22As shown, the potatoes enter the multi-stage screening limit feeding device described in Example 1, and the structure of driving the transmission shaft I-03 to rotate through the power device to drive the rotation of the carrier plate I-02 provides friction to the potatoes. Any one of the two ends of the long axis of the potato, so according to the translation theorem of force:

[0078] The force acting on the rigid body can be equivalently moved from the original point of action to any point in the rigid body in parallel. At the same time, a force couple is added, and the force couple is the moment of the original force to the new point of action. Get the force and force couple M=l×f1 whose size is the same as f1, and make the potato rotate. Among them, I is the distance from the friction point to the center of gravity of the potato. A...

Abstract

The invention discloses a multi-stage screening limit feeding device and method. The technical scheme is that the device comprises a limiting rail, a bearing plate, a driving device and a limiting mechanism. A bearing plate is arranged below the head end of the limiting rail. The bearing plate can rotate relative to the limiting rail under the action of the driving device. A multi-layer sorting rail is arranged at the tail end of the limiting rail and provided with a sorting groove. The limiting mechanism is fixed to one side of the limiting rail. The device can screen out materials of different quality levels and can realize the orderly conveying of the materials.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a multi-stage screening limit feeding device and method. Background technique [0002] For vegetatively propagated root crops, root tubers are used for sowing. Cutting the roots of vegetatively propagated root crops into pieces can obtain roots within a preset weight range. Potatoes are vegetatively propagated root crops, which are sown in tubers. It is advisable to control the quality of the whole seed potato to be cut at 50-160g. If it is less than 50g, it will not be cut into pieces and directly enter the mixing system. If it is more than 160g, it will be directly screened and rejected. Therefore, it is necessary to screen and classify seed potatoes of different quality grades to ensure that they can have rich nutrient supply, thereby having better drought resistance and growth rate. [0003] In recent years, with the in-depth research on mechanized potato planting techn...
