Description

sweet potato harvester

technical field

The invention provides a sweet potato harvester, which belongs to the technical field of agricultural machinery.

Background technique

Sweet potato has a wide planting area in my country. It is planted in the south of 40 degrees north latitude. It has strong adaptability to soil, good acid and alkali resistance, and can adapt to the range of soil pH 4.2-8.3. The yield is 2500-5000 kg.

Sweet potatoes are rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. The sugar content reaches 15-20%. It is called "longevity food" and can be processed into a variety of foods, such as vermicelli, vermicelli, vermicelli, sweet potato cake, pancakes, etc.

Because sweet potatoes like sandy soil, they are planted in ridges when they are afraid of waterlogging. They are root crops. The harvesting of sweet potatoes is mainly manual. The sweet potatoes are planted with a pout, and the sweet potatoes are dug out from the soil, and the sweet potato seedlings are removed by hand. , low efficiency and many processes.

Contents of the invention

The purpose of the present invention is to provide a fully automatic combined mechanical harvester for sweet potatoes, which can realize excavation, separation of sweet potatoes and soil clods, separation of sweet potatoes and sweet potato seedlings, cleaning of sweet potato surfaces, and automatic collection at one time, so as to reduce manual harvesting costs and labor intensity , The harvesting efficiency is high, and the technical problem of sweet potato mechanized harvesting is completely solved.

Its technical scheme is.

Including tractor, excavation shovel, vibrating screen, conveying screen and silo, there is an excavation shovel on the frame, the excavation shovel scoops up the sweet potato ridge soil, scoops the sweet potato together with the soil block, and excavates the sweet potato and the soil block along the excavation shovel Surface movement enters the vibrating screen. One end of the vibrating screen is connected to the frame by a link hinge, and the other end is connected to the eccentric link set on the power wheel. The vibrating screen and the frame are inclined. The sieve reciprocates, the vibrating sieve vibrates to crush the soil clods, and separates the soil adhering to the surface of the sweet potatoes and falls along the sieve holes. The food falls through the sieve holes of the conveying sieve, and the sweet potatoes enter the collection bin.

In the sweet potato harvester described above, the vibrating screen is composed of bars that run through the screen frame at a certain distance. The included angle is 10-20 degrees.

In the sweet potato harvester described above, the conveying screen is composed of rods penetrating the screen frame at a certain distance, and there are multiple connecting reinforcement rings between the two rods. The rubber sleeves on the rods are made of flexible silicone material. become.

The sweet potato harvester described above is equipped with a tension spring in the silo, the angle between the bottom surface of the silo and the horizontal line of the ground is 40-60 degrees, when the sweet potatoes in the silo reach a certain weight, the discharge port of the silo is opened, and the silo automatically unloading.

Compared with the prior art, the present invention has the following advantages.

1. The self-propelled structure is adopted, so that all the harvesting mechanisms are gathered together to reduce the transmission distance.

2. One end of the vibrating screen is hinged to the frame, and the other end is set at an angle of 20 degrees to the ground with the eccentric connecting rod on the power wheel. Using the dustpan principle, the separation of potato soil and potato stone is realized. The bar runs through the screen Frame, the distance between the two rods is less than 30 mm of the minimum diameter of the sweet potato. A silicone sleeve is provided on the rod to prevent the skin from being damaged when the sweet potato is turned over on the rod. strength.

3. The conveying sieve has a large width, and there are multiple connecting and reinforcing rings on the two bars to prevent the bar from being deformed due to excessive harvesting weight. The eccentric connecting rod is used to separate the potato seedlings and remove the soil attached to the surface of the sweet potato.

4. There is a tension spring in the silo, and the bottom surface of the silo is inclined. When the sweet potatoes in the silo reach the set weight, the discharge port of the silo is opened, and the sweet potatoes flow out from the discharge port, realizing automatic unloading. Finally, under the action of the tension spring, the discharge port is closed, and it can also enter the collection vehicle, eliminating the need for manual picking.

5. There are multiple excavation devices on the frame, and the depth of the excavation devices is adjustable. The excavation depth is 30-40 cm, and multiple rows of operations can be performed at one time.

Detailed ways.

In the embodiment shown in 1 to 2, a sweet potato harvester includes a tractor 1, a digging shovel 2, a vibrating screen 4, a conveying screen 7 and a silo 9, and adopts a backpack structure, which is compact in structure and shortens the transmission distance. Frame 3 installs excavation product 2, vibrating screen 4, conveying screen 7 and feed bin 9 in sequence, tractor 1 power output shaft drives power wheel 5 to rotate, tractor 1 drives multiple excavation products 2 to scoop up sweet potato ridge soil, excavation product 2 depth Adjustable, the depth is 30 cm. Shovel up the sweet potato and the soil block together. The sweet potato and the soil block move along the excavation surface of the excavating shovel 2 and enter the vibrating screen 4. One end of the vibrating screen 4 is connected to the frame 3 by a connecting rod hinge, and the other end Connected with the eccentric link 12 arranged on the power wheel 5, the vibrating screen 4 is composed of rods 10 penetrating the screen frame at a certain distance, and the rods 10 are provided with rubber sleeves. The angle between the vibrating screen 4 and the horizontal line of the ground is 20 degrees, driven by the power wheel 5, the eccentric link 12 drives the vibrating screen 4 to reciprocate, the shaking of the vibrating screen 4 shatters the soil clods, and separates the soil adhered to the surface of sweet potatoes and falls along the screen holes to realize the separation of potato and soil Separated from potato rocks, the large bar of the vibrating screen 4 is made of solid round steel. In order to increase the separation effect, the vibration frequency is greater than 2 times per second. The sweet potato moves along the vibrating screen 4 and enters the conveying screen 7, which is separated by a certain distance. It is composed of rods 10 that run through the screen frame, and there are multiple connecting and reinforcing rings 11 between the two rods 10. The rods 10 are provided with rubber sleeves made of flexible silica gel materials. The conveying screen 7 is intermittently Shake to clean up the dirt and sundries on the surface of the sweet potatoes. The sundries fall from the sieve hole of the conveying screen 7, and the sweet potatoes enter the collection bin 9. In the bin, 9 is provided with a tension spring 8. The bottom of the bin is inclined, and the ground of the bin 9 is connected to the ground. The included angle of the horizontal plane is 50 degrees. When the sweet potatoes in the hopper 9 reach the set weight, the discharge port of the hopper 9 is opened, and the sweet potatoes flow out from the discharge port to realize automatic discharge. After unloading, under the action of the tension spring , the discharge port is closed, and the silo 9 is automatically discharged.
