Description

TECHNICAL FIELD

[0001] The utility model relates to a pepper harvesting mechanical technical field further is a blowing device of pepper harvesting device. BACKGROUND

[0002] In the pepper planting field, especially in large area pepper planting, there is a problem of harvesting mature pepper, and the current harvesting is divided into manual harvesting and mechanical harvesting.

[0003] The working principle of the pepper harvesting machine in the prior art is that the high-speed rotating tooth roller rotates the pepper fruit from the pepper plant and guides it to the longitudinal conveying belt (the specific structure is generally a central longitudinal conveying belt, and two lateral conveying belts on both sides, and the lateral conveying belts guide the pepper fruit on both sides to the central longitudinal conveying belt), and then the longitudinal conveying belt transmits it to the rear storage box. The existing pepper harvesting machine has the following defects: the tooth roller rotates at high speed. This is because the pepper fruit needs to be rotated by the tooth roller from the roller and guided to the longitudinal conveying belt by the inner wall of the roller, which requires the tooth roller to rotate at a high speed, and the tooth roller usually rotates at a speed of more than 300 rpm. On the contrary, if the tooth roller rotates at a low speed, the pepper fruit will not get the corresponding linear speed and will eventually fall to the ground. However, high-speed rotation of the tooth roller will cause various problems: 1. High breakage rate of pepper fruit. The collision of pepper fruit with the tooth roller and the inner wall of the roller causes a high breakage rate of pepper fruit, which usually reaches 10-15%. The broken pepper fruit will affect the sales price due to its poor appearance. On the other hand, the broken pepper fruit shell is broken, and the pepper seeds inside will fall off, reducing the weight of the pepper fruit and affecting the sales revenue. Especially, since some peppers are sold at a high price, this breakage rate will significantly reduce the income of the grower. 2. High impurity rate. The high-speed rotation of the tooth roller will rotate the pepper fruit, leaves and stems at the same time and guide them into the storage box, thereby increasing the impurity rate, which will increase the burden of future impurity removal.

[0004] At present, the cost of manual harvesting is about 1500 yuan per mu, while the cost of mechanical harvesting is only about 400 yuan per mu. Although the cost of manual harvesting is high, the comparative benefit is still worthwhile due to the low breakage loss of manual harvesting. Therefore, the existing pepper growers (especially large area pepper growers) prefer to use manual harvesting. This is a helpless choice, which will undoubtedly affect the income and harvesting efficiency of the pepper grower. If the breakage rate of mechanical harvesting can be significantly reduced, the current situation will be changed.

[0005] Based on this, the utility model person has developed a new type of "pepper harvesting device blowing device". CONTENT OF THE UTILITY MODEL

[0006] The utility model discloses a purpose at providing the blowing device of pepper harvesting device, and the device can make the gear roll rotation speed drop, thereby solve the high speed rotation of gear roll in the prior art and bring the high rate of broken of pepper fruit and other defects.

[0007] The utility model discloses a purpose is realized through following scheme:

[0008] The blowing device of pepper harvesting device, the gear roll cylinder is provided with gear roll in the front part of pepper harvesting device, and it is characterized in that: fan is arranged on the top of gear roll cylinder, air duct is arranged in front of fan, and air outlet is arranged below air duct, and the air outlet points to the rear top of gear roll cylinder.

[0009] Further:

[0010] The gear roll, the tooth is straight tooth or curved tooth.

[0011] The air duct is arc or polyline of multiple straight line segments.

[0012] The rear top is inclined to the horizontal rear top at an angle of 30-60 degrees.

[0013] The air outlet is a rectangle or an oval large opening, or multiple rectangle or oval small openings.

[0014] The utility model discloses the beneficial effect is: the gear roll rotation speed of the machine is only 100-150 turns / min, and this improvement produces following effect: 1, the broken rate of pepper fruit is low, and the gear roll rotation speed can significantly reduce the damage to pepper fruit.

[0015] In order to make the personnel in the technical field better understand the utility model scheme, and make the above-mentioned purpose, feature and advantage of the utility model can be more obvious and easy to understand, the utility model is further explained in detail below with examples. BRIEF DESCRIPTION OF DRAWINGS

[0016] Figure 1 For the structure schematic diagram of the utility model, Figure 2 For another gear roll structure schematic diagram, Figure 3 For another structure schematic diagram of the utility model.

[0017] In the drawing: tooth 1, roll 2, air outlet 3, air duct 4, fan 5, gear roll cylinder 6, conveying belt 7. DETAILED DESCRIPTION

[0018] As Figure 1As shown, the blowing device of the pepper harvesting device, the tooth roller in the tooth roller cylinder 6 is provided with a tooth roller, the tooth roller includes a tooth 1 and a roller 2, a fan 5 is arranged above the tooth roller cylinder, a wind channel 4 is arranged in front of the fan 5, and an air outlet 3 is arranged below the wind channel 4, and the air outlet 3 is directed to the upper rear of the tooth roller cylinder 6.

[0019] The upper rear refers to a horizontal rear upward inclination angle of Φ=20-60 degrees, and further Φ=30-60 degrees. The angle is set to adopt blowing to cooperate with the rotation of the tooth roller to ensure that the peppers fall to the conveying belt 7.

[0020] The tooth roller, the tooth 1 is a straight tooth (see Figure 1 ) or a curved tooth (see Figure 2 ).

[0021] The wind channel 4 is arc-shaped (see Figure 1 ) or polyline-shaped (see Figure 3 ) of multiple straight line segments.

[0022] The air outlet 3 is a rectangular or elliptical large opening, or multiple rectangular or elliptical small openings.

[0023] It should be noted that: due to the addition of a fan, the power consumption will increase moderately, but due to the reduction of the tooth roller speed, the tooth roller speed is less than half of the existing technology, the overall power increase will not be too high, and compared with the large decrease of the pepper fruit breaking rate, the power consumption generated by the increase can be ignored.

[0024] In use, although the tooth roller rotates at low speed, it can still blow the peppers onto the conveying belt 7 (the conveying belt 7 in Figure 1 is a longitudinal conveying belt, and there is also a transverse conveying belt on both sides of the longitudinal conveying belt, which guides the peppers to the longitudinal conveying belt), and the conveying belt 7 guides the peppers to the rear storage box. In this way, it is avoided that in the traditional technology, high-speed rotation is used to guide the peppers to the conveying belt 7 from the inner wall of the tooth roller cylinder 6, thereby avoiding various disadvantages caused by high-speed rotation of the tooth roller to harvest peppers.

[0025] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
