[0002] Pepper has high nutritional value and is rich in vitamins. It can be eaten as a fresh vegetable or used as a seasoning. It is a popular vegetable in daily life. Pepper has many processed products with high added value. It is one of the vegetables with the largest planting area in my country. Pepper is also an important source of natural red pigment. It is widely used in food coloring and industrial raw materials, etc., and has high economic value.

[0003] Chili peppers are widely grown in my country, with a large planting area. The total output ranks first in the world, and the growth rate of chili pepper sales has remained above 7%. However, the harvesting method is still mainly manual, which is not only costly but also has extremely low harvesting efficiency.

[0004] my country started late in the research and development of pepper harvesters. Only in recent years have a few large pepper harvesters emerged, and these machines are mainly used in large-scale plain planting areas. However, pepper planting in my country is spread across plains, hills and mountains, and the pepper varieties, terrain characteristics and planting patterns grown in different regions are different. Especially in mountainous or hilly areas, large harvesters are difficult to exert their effectiveness. Therefore, in order to promote the mechanization and automation of pepper harvesting, the research and development of small pepper harvesters that can adapt to diverse terrains and pepper varieties has extremely important research value and practical significance.

DETAILED DESCRIPTION

[0040] The overall movement process of the device

[0041] The present invention provides a small-sized gear-rolling pepper harvester, which will be further described below in conjunction with the accompanying drawings.

[0042] like Figure 2 As shown, the machine mainly comprises a grass roller (5) at the front end of the vehicle body for bending pepper plants and making them rebound, a harvesting roller (7) at the front of the vehicle body for picking peppers, an arm (15) for adjusting the height of the harvesting roller, a vibration transmission mechanism (6) at the upper middle part of the vehicle body, a transmission box (2) at the lower middle part of the vehicle body, a cutting shaft system (11) for cutting and pushing aside pepper stems, a storage box (8) at the rear of the vehicle body, and a lever mechanism (9) above the storage box.

[0043] like Figure 5As shown, the grass roller (5) is connected to the hole on the vehicle frame (19) through a raised rotating shaft, and the height of the grass roller (5) can be adjusted by using a telescopic rod (14), so as to meet the needs of different pepper plants. At the same time, the grass roller (5) is connected to the internal components through a bearing, so as to achieve rotation, converting sliding friction into rolling friction, greatly reducing the friction force on the contact surface with the plant. When working, the grass roller (5) is adjusted to a suitable height, so that the pepper plant can be bent and rebounded by the grass roller (5) and just come into close contact with the rolling teeth (18) on the harvesting drum (7).

[0044] like Figure 2 The harvesting drum (7) is connected to the arm rods (15) on the left and right sides through the main shaft (4), and a sprocket is connected to one end of the main shaft (4) to realize power transmission.

[0045] like Figure 3 As shown, the motor (1) is connected to the first horizontal shaft (20) through a coupling, the first horizontal shaft (20) is connected to the second horizontal shaft (21) and the third horizontal shaft (22) in sequence through spur gears, and the third horizontal shaft (22) is connected to the main shaft (4) through a sprocket for transmission; the first horizontal shaft (20) is connected to the vertical shaft (10) through a bevel gear, and the vertical shaft (10) is connected to the cutting shaft system (11) through two spur gears, thereby achieving coaxial but different speeds of the cutting shaft system (11).

[0046] like Figure 4 As shown, the lever mechanism is a four-bar mechanism driven by a small motor (30). When working, the small motor (30) drives the lever to rotate to level the peppers in the storage box (8), thereby preventing the peppers from piling up into a spire shape and improving the space utilization of the storage box.

[0047] like Figure 6 , Figure 7 As shown, a fixing ring (16) with a semicircular hole is used inside the harvesting drum (7), which fits with the round tube with a semicircular cross-section, and eight M6*700 studs are used to simultaneously complete the axial and radial fixation of the hobbing shaft (17). Finally, four M6*55 bolts are used to press the roller end cover (29) against the roller end face, and at the same time, the inner ring of the roller end cover (19) is pressed against the shaft shoulder to complete the axial fixation of the key. The hobbing (18) is directly mounted on the hobbing shaft (17), and the spacing of the hobbing (18) can be adjusted as needed.

[0048] like Fig. 9As shown, the shaft hole on the large end of the arm (15) is used to connect with the main shaft (4), the pin holes on both sides are used to connect with the latch, and the small end of the arm (15) has a shaft for connecting with the hole on the vehicle frame (19). By rotating the arm (15), the working height of the harvesting drum (7) can be adjusted within several gears to adapt to peppers of different varieties and different growth conditions. After the gear is selected, it can be fixed by the latch on the arm (15).

[0049] like Fig.10 As shown, the gap between the teeth of the spring-tooth baffle (31) is just enough for the rolling teeth (18) to pass through, so that the spring-tooth baffle (31) can pull the peppers that cannot be directly thrown out off the rolling teeth (18).

[0050] The vehicle weighs about 180kg. The power of each component of the harvester comes from the 1500W brushless mid-mounted motor equipped in the vehicle, and the energy is provided by a 72V battery. The machine itself is a non-powered agricultural machine and needs to be towed by a tractor, motorcycle or other power source.

[0051] like Figure 2 As shown, when working, the motor (1) drives the sprocket (3) on the side of the vehicle body to rotate through the transmission box (2), and then drives the harvesting drum (7) to rotate through the chain drive. When the vehicle body moves forward, the grass roller (5) bends the pepper plant in the process of moving forward, and uses the plant's own toughness to closely contact the rolling teeth (18) on the harvesting drum (7) during the rebound process. The high-speed rotating human finger-shaped rolling teeth (18) are inserted into the pepper plant to pick the pepper fruit and part of the stems and leaves together. During the rotation process, part of the pepper is directly thrown into the storage box (8) at the back, and part of the pepper is separated from the harvesting drum (7) under the action of the vibration transmission mechanism (6), and then falls into the storage box (8).

[0052] The teeth of the vibration transmission mechanism (6) and the tooth shapes of the harvesting rolling teeth (7) are arranged in a staggered manner, and the peppers between the tooth gaps will be stopped by the baffle. The vibration transmission mechanism (6) has a certain slope and during the vibration process, the pepper fruits and stems and leaves remaining on the baffle will enter the collection box (8).

[0053] The pepper fruits entering the collection box (8) will gradually pile up, and the lever mechanism (9) will be continuously moved after being started, so that the pepper fruits piled up in a spire shape can be flattened, so that the pepper fruits can be evenly spread in the collection box, thereby improving the space utilization rate of the collection box.

[0054] Movement flow of the stalk cutting function

[0055] The motor (1) transmits the rotational motion of the horizontal axis to the vertical axis (10) through the bevel gear transmission, and the vertical axis (10) transmits the power to the cutting axis system (11) through the gears. Fig.11As shown, the core of the cutting shaft system (11) is a stepped shaft (23), which is connected to a frame (25) through two angular contact ball bearings (24) at the upper end, and connected to a large sleeve (27) through two angular contact ball bearings (26) at the lower end. The stepped shaft (23) and the large sleeve (27) are respectively connected to spur gears (28 and 32) with different numbers of teeth, thereby achieving coaxial but different speeds. The stepped shaft (23) is connected to the cutting blade (13) and rotates at a faster speed; the large sleeve (27) is connected to the star-shaped paddle (12) and rotates at a slower speed.

[0056] As the vehicle moves forward, the pepper plants picked by the rolling gear (18) are pressed into the bottom of the vehicle, and the slowly rotating star-shaped paddle (12) pushes the cleanly picked pepper plants to one side, while the rapidly rotating cutting blade (13) cuts off the pepper plants. The rotation of the star-shaped paddle (12) can also prevent the cut pepper plants from being entangled on the cutting blade (13).
