Description

A kind of sweet potato harvesting with soil impurities screening separator

technical field

The invention relates to the technical field of sweet potato screening, in particular to a screening and separator with soil impurities for sweet potato harvesting.

Background technique

Sweet potato is an annual or perennial creeping herb, also known as sweet potato, sweet potato, sweet potato, etc. Sweet potato cultivation in my country is mainly based on ridge planting. The main production links include land preparation, fertilization, ridge raising, transplanting, field management, stem and vine harvesting, and harvesting and transportation. The harvesting process of potato (potato, sweet potato) crops mainly includes: removing stems and leaves, digging, separating, picking up and loading and transporting.

Among them, in the process of separating sweet potato and soil, the existing separation methods are mostly used: 1. manual removal; 2. mechanical filter screen for removal; manual removal can only be used in a small amount of planting, and for Large-scale farms need to use a mechanical filter screen to remove the soil. In actual use, we found that the mechanical filter screen uses the vibration principle to automatically separate the sweet potato and the soil block, and the sweet potato itself collides with the soil block to remove large particles. The mud blocks are impacted into small particles of mud and then fall out of the mesh, which is inefficient. On the one hand, it is easy to damage the surface of the sweet potato. On the other hand, the filter screen needs to be cleaned regularly, which has the disadvantage of being easy to block. We propose a new type of sweet potato harvester with soil impurities screening separator to separate sweet potato and soil lumps.

At the same time, the sweet potato is prevented from falling, and at the same time, the sweet potato is clamped and conveyed to the first sweet potato discharge port 102 by the gap between the two adjacent clamping rods 503, and the soil block falls from the gap of the clamping rod 503 to the bottom. In the crushing groove 703, crushing is achieved by the first crushing plate 505 and the second crushing plate 702 being attached to each other. A crushing plate 505 extends in the opposite direction. The advantage of this setting is that it can remove the mud blocks between the adjacent clamping rods 503 to prevent clogging. On the other hand, it shrinks when rotating upward to avoid damaging the surface of the sweet potato. When the material port 201 enters the second separation box 2, the flushing mechanism 208, the drying mechanism 207 and the second transmission mechanism are activated, so that the sweet potato moves toward the second sweet potato discharge port 202 while the flushing mechanism 208 passes through the flushing nozzle. 210 Rinse the sweet potato, so that the soil on the surface is washed and discharged through the second soil discharge port 204, and finally the sweet potato after drying through the drying nozzle 211 is discharged from the second sweet potato discharge port 202 to complete the sweet potato and soil. separation.

In the present invention, the traditional screen is changed into two side plates 502 and a plurality of clamping rods 503 are installed between the two side plates 502 to realize the conveying of sweet potatoes by means of rotation. Therefore, the existence of the clamping rods 503 makes the While keeping a gap between the two adjacent first rotating rollers 5, the sweet potato is prevented from falling, and at the same time, the sweet potato is clamped and conveyed in the direction of the first sweet potato discharge port 102 by the gap between the two adjacent clamping rods 503. , the soil block falls from the gap of the clamping rod 503 into the crushing groove 703 below, and is crushed by the first crushing plate 505 and the second crushing plate 702 being attached to each other;

However, when the first crushing plate 505 is rotated to the top, it shrinks in the axial direction of the sleeve 504, and when it is rotated to the bottom, the first crushing plate 505 extends in the opposite direction. The advantage of this setting is that the adjacent clamping rods 503 can be removed. The dirt blocks in between prevent clogging and on the other hand shrink when turning upwards to avoid damaging the surface of the sweet potato;

Since the second separation box 2 is provided, and the washing mechanism 208 and the drying mechanism 207 are arranged in the second separation box 2, the sweet potato can be thoroughly cleaned, and the soil on the surface of the sweet potato can be further separated.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Equivalent replacements or changes to the inventive concept shall all fall within the protection scope of the present invention.
