Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery engineering technology, specifically relating to a potato vine harvester. Background Technology

[0002] Potato vines are high in nutrients, and potatoes, as my country's fourth largest grain crop, have a very high yield. However, the harvesting and utilization of potato vines is poor. Manual harvesting is cumbersome, inefficient, and labor-intensive, severely hindering the industrial production of potato vines for silage. This necessitates a high-efficiency potato vine harvester suitable for harvesting vines with high moisture content to improve processing efficiency, reduce labor costs, and increase the level of automation in production.

[0003] Currently, domestically available harvesters are generally used for harvesting tall crops such as corn and sweet sorghum, or short crops planted on flat land. They are not suitable for crops like potatoes grown using a raised-ridge planting method. While foreign self-propelled silage harvesters typically employ a modular design, these harvesting machines are not yet suitable for harvesting potato vines. Potato vine harvesting occurs during the potato maturity stage, at which point the stalks are severely lodged. Using existing equipment for this process results in low harvesting efficiency, high operating costs, high impurity content, and compromised silage quality. Utility Model Content

[0004] The purpose of this invention is to provide a potato vine harvester that achieves both harvesting and crushing of potato vines, ensuring smooth harvesting and thorough crushing by reducing the moisture content of the potato vines during the crushing process.

[0005] This utility model adopts the following technical solution: a potato vine harvester, comprising: a cutting platform, a crushing section, and a blower, wherein:

[0006] The cutting platform is connected to the crushing section via a conveying device; the cutting platform is used to harvest potato vines and cut them in one go; the conveying device is used to transport the cut potato vines to the crushing section.

[0007] The crushing section is located at the rear outlet of the conveying device. It includes a horizontally arranged housing, and roller blades and hammer crushers are arranged at intervals in front and behind the housing. Both roller blades and hammer crushers are arranged in the left and right directions and are parallel to each other.

[0008] An air inlet and a material outlet are respectively provided on the left and right shells of the housing, and behind the hammer crusher.

[0009] A hot air blower is located on the left side of the casing, at the air inlet, and the hot air outlet of the hot air blower is connected to the air inlet.

[0010] A buffer chamber is located on the right side of the outer casing, at the discharge port, and is connected to the discharge port. A blower is located below the outer casing, and the blower's outlet is connected to the buffer chamber. A vertical conveying pipe is connected to the upper part of the buffer chamber, and the upper outlet of the conveying pipe extends to the material collection device.

[0011] Furthermore, a curved tube is integrally connected to the upper end of the conveying pipe, and the curved tube is U-shaped with its opening facing downwards.

[0012] Furthermore, the material collection device is a rectangular bin with an open top, used to receive the blown material.

[0013] Furthermore, a spiral conveyor is installed behind the cutting platform. The spiral conveyor is a horizontally arranged spiral shaft that is parallel to the stalk. It is used to gather the potato vines after one cut by the cutting platform to the left or right and send them to the conveying device.

[0014] Furthermore, the crushing part is mounted on a base, and a tracked travel device is mounted on the lower end of the base.

[0015] The beneficial effects of this invention are: 1.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] This utility model relates to a potato vine harvester, such as... Figure 1 and 2 As shown, it includes: a cutting platform 1, a crushing section 3, and a blower 5, wherein:

[0024] The cutting platform 1 is connected to the crushing section 3 via the conveying device 2; the cutting platform 1 is used to harvest potato vines and cut them in one go; the conveying device 2 is used to transport the cut potato vines to the crushing section 3.

[0025] The crushing section 3 is located at the rear outlet of the conveying device 2. It includes a horizontally arranged shell, in which a roller blade 12 and a hammer crusher 13 are arranged at intervals. The roller blade 12 and the hammer crusher 13 are arranged horizontally and parallel to each other. The roller blade 12 is used to cut the potato vines a second time after the first cut and convey them to the front end of the hammer crusher 13. The hammer crusher 13 is used to crush the potato vines after the second cut.

[0026] An air inlet and a material outlet are respectively provided on the left and right shells of the housing, and behind the hammer crusher 13.

[0027] A hot air blower 10 is provided on the left side outside the housing, at the air inlet, and the air outlet of the hot air blower 10 is connected to the air inlet.

[0028] A buffer chamber is provided on the right side outside the housing, at the discharge port, and the buffer chamber is connected to the discharge port. A blower 5 is provided below the buffer chamber, and the air outlet of the blower 5 is connected to the buffer chamber. A vertical conveying pipe is connected to the upper part of the buffer chamber, and the upper outlet of the conveying pipe extends to the material collection device 6.

[0029] A curved tube is integrally connected to the upper end of the conveying pipe. The curved tube is U-shaped with its opening facing downwards.

[0030] The material collection device 6 is a rectangular bin with an open top, used to receive the blown material.

[0031] A spiral conveyor 9 is provided behind the cutting platform 1. The spiral conveyor 9 is a horizontally arranged spiral shaft and is parallel to the shovel. It is used to gather the potato vines after one cut by the cutting platform 1 to the left or right and send them to the conveying device 2.

[0032] The crushing part 3 is mounted on the base, and a tracked driving device 7 is mounted on the lower end of the base.

[0033] The header 1 employs an eccentric reel, comprising a horizontally positioned drum with a rotating shaft coaxially mounted inside. Reel discs are coaxially fitted at both ends of the drum. Multiple reeling rods are positioned between the two reel discs, spaced apart around the reel. Each reel has multiple reeling teeth spaced along its length. A bucket-shaped housing is located at the lower part of the reel, with multiple cutters 8 positioned at the front end of the housing. These cutters 8 are spaced apart along the left-right direction of the housing and are used to cut potato vines from the ground.

[0034] An eccentric reel is used, which can effectively move most of the potato vines to the cutting section, and then move them to the conveyor section at the rear after cutting.

[0035] The conveying device 2 includes two rotating wheels spaced apart, with the rear rotating wheel positioned higher than the front rotating wheel. The two rotating wheels are connected by a conveyor belt, the front end of which is used to receive the cut potato vines and transport them to the rear outlet.

[0036] The roller blade 12 and the hammer-type crusher 13 are parallel to each other, and the blades are made of tempered steel. After harvesting, the potato vines are first cut by the roller blade and then chopped by the hammer blade, and then pushed backward by the thrust of the blades to the air outlet.

[0037] Given that potatoes are typically grown using a raised bed planting method and the soil conditions in most potato-growing mountainous areas, a tracked system is used to ensure smooth and stable movement.

[0038] The potato vines pulled by the reel cutter 8 are cut off. The cutter is made of manganese steel, which can ensure cutting efficiency.

[0039] like Figure 3 , 4As shown, after the potato vines enter the crushing section, the hot air blower 10 operates, generating hot air. Simultaneously, the roller cutter 12 and hammer cutter 13 completely crush the potato vines, which then enter the blowing zone of the subsequent blower 5. The crushed potato vines rise with the upward airflow from the blower and enter the storage hopper through a pipe. The hot air blower 10 serves two purposes: firstly, it reduces the moisture content of the potato vines; secondly, it delivers the crushed potato vines into the blowing zone of the blower 5, acting as a conveyor. The hot air outlet (14) of the hot air blower 10 faces the air inlet and is aligned with the discharge outlet, ensuring that the hot air and crushed potato vines can smoothly enter the blowing zone of the blower 5. The blower 5 generates a vertically upward airflow, which then delivers the potato vines into the material collection device 6.

[0040] The hot air blower has 10 parameters: a matched motor with a rated power of 5 kW, an estimated air volume of 100 cubic meters per hour, an air pressure of 200 Pa, a speed of 400 rpm, and a noise level not exceeding 65 decibels. Combined with... Figure 2 In the top view, the hot air outlet 14 of the hot air blower 10 is not completely aligned with the conditioning wheel. This is mainly to prevent the wind from blowing the potato vines and reducing the crushing effect. The hot air is blown in from the rear and fully fills the crushing part, which also achieves the effect of raising the temperature of the crushing part and reducing the moisture content. The entire hot air blower 10 is fixed to the base by bolts 15.

[0041] like Figure 5 As shown, this harvester uses a power input shaft 16 to power the reel, which pulls the potato vines to the cutter 8 for cutting. After cutting, the auger pusher 11 pushes the vines onto the inclined conveyor 2. The conveyor belt shaft 17 transmits power to the conveyor belt, which then transports the potato vines from the inclined conveyor 2 to the crushing section 3. The power input shaft 16 connects the reel and the rotating shaft at the front of the conveyor device, which simultaneously drives the reel and the conveyor belt shaft of the conveyor device 2 to rotate. The ratio of the transport speed to the reel speed is a fixed value to facilitate driver control. Because the potato vines have a high water content, the belt ensures that the potato vines do not stick together, thus maintaining good transport efficiency. In actual operation, the driver controls the driving speed to match the harvesting speed, transport speed, and crushing speed to ensure harvesting efficiency.

[0042] The working process of a potato vine harvester of this utility model is as follows: After the driver starts the machine, the tracked driving device 7 starts to move. The power output shaft 16 drives the reel and the conveyor belt shaft 17 to work. The reel moves the potato vines into the cutter 8. After the cutter cuts the potato vines, the reel moves them into the spiral conveyor 9. The spiral conveyor 9 gathers the potato vines moved by the reel after cutting to the side of the machine. Then, the telescopic finger moves them to the conveyor device 2. The belt of the conveyor device 2 ensures that the potato vines run smoothly and are transported to the crushing part 3. In the hot air generated by the hot air device 10, the roller blade 12 and the hammer blade 13 rotate at high speed to crush the potato vines thoroughly. Then, the blower 5 blows the potato vines out from the discharge port 11 to the material collection device 6.
