Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a combined air-blowing and brushing device for removing frost-resistant soil from grapevines. Background Technology

[0002] Grapes are a warm-season crop with poor cold tolerance. China has a wide grape-growing area, boasting the largest grape-growing region outside of Europe. Most of the high-quality grape-producing areas are located in the north, where grapes are grown outdoors on trellises. Due to the cold and dry winters in the north, the pruned grapevines must be removed from the trellis and buried in the soil before winter, only to be unearthed and replanted in the spring when the weather warms up. Because the process of removing grapevines is highly seasonal, labor-intensive, and costly, mechanization is an inevitable trend.

[0003] In recent years, many scholars have studied different types of soil removal machines for grapevines under the burial system for winter protection. These include methods such as using a combination of rotating impellers and scrapers to remove soil from the sides of the ridges, and using a combination of augers and protective fabric to remove the soil. The main components of these soil removal machines include scrapers, augers, and impellers. The disadvantages of these devices are that most are rigid components. Because grapevines are irregularly distributed in the ridges, it is difficult for operators to adjust the position of the soil removal components in real time according to the location of the vines. This can lead to accidental contact between the rigid components and the vines, damaging them and affecting the quality and yield of the following year's grapes. Avoiding the vines during operation results in low soil removal efficiency and poor cleaning effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a combined air-blowing and brush-type soil removal device for grapevines. This device addresses the problems of rigid soil removal components easily damaging grapevines and low work efficiency encountered in spring soil removal operations for grapevines in northern China. It is designed as an air-blowing and brush-type soil removal device that combines a rotating brush with high-pressure airflow for soil removal.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A combined air-blowing and brushing device for removing soil from grapevines to protect them from frost, comprising a main frame 5, characterized in that it further comprises a transmission device, a blower device, and a brushing device installed on the main frame 5; the transmission device is used to transmit the power of PTO to the blower device and the brushing device, the blower device is used to blow air into the brushing device, and the brushing device is used to blow away the soil protecting them from frost. The combing device includes a hollow combing shaft with multiple layers of bristles 1702 installed in the lower part of the combing shaft. An inward-retracting air nozzle 1704 is provided between each layer of bristles 1702 near the ground. The hollow combing shaft and the inward-retracting air nozzle 1704 are used to discharge air pressurized by the blower to blow away the frost-proof soil.

[0006] Based on the above plan, The comb shaft includes: an airflow main pipe 1709, a brush upper end connecting shaft 1708, a brush roller connecting end 1707, a brush roller end cap 1706, a brush roller 1705, and a brush spacer 1703, which are fixedly connected to each other from top to bottom. Multiple layers of bristles 1702 are installed on the brush roller 1705 and the brush spacer 1703. The brush spacer 1703 has multiple inward-curving air nozzles. The bottom cap 1701 of the brush roller is fixedly installed at the bottom of the brush sleeve 1703.

[0007] Based on the above plan, The bristles 1702 are made of a flexible material.

[0008] Based on the above plan, The blower device includes a left-handed centrifugal fan 12, which delivers pressurized air to the hollow comb shaft through an airflow duct 14.

[0009] Based on the above plan, The transmission device includes a three-head gearbox 6, which is connected to the fan drive pulley I7 and the brush drive pulley 20 and provides them with power. The fan drive pulley I7 is connected to the fan driven pulley I9 and the fan drive pulley II11, which are fixedly connected to the same axis via belt 8. The fan drive pulley II11 and the fan driven pulley II19 are connected by belt. The fan driven pulley II19 drives the blower to blow air. The brush drive pulley 20 and the brush driven pulley 15 are connected by a belt, and the brush driven pulley 15 is coaxially and fixedly connected to the comb shaft.

[0010] Based on the above plan, The main frame 5 includes a main frame 0501, two three-point suspension lower lugs 0502 are fixedly installed on the main frame 0501, a three-point suspension rod 0504 is fixedly installed on the upper part of the two three-point suspension lower lugs 0502, a three-point suspension upper lug 0505 is provided in the middle of the upper part of the three-point suspension rod 0504, the three-point suspension upper lug is connected to the three-point suspension rear lug 0507 through a pull rod 0506, and the three-point suspension rear lug 0507 is fixedly installed on the main frame 0501.

[0011] The main frame 0501 is also fixedly equipped with a three-head gearbox bracket 0503, a bearing box bracket 0508, an air pipe bracket 0509, and a bearing bracket 0510.

[0012] The beneficial effects of the air-blowing comb-brush combined grapevine frost-prevention soil removal device described in this utility model are as follows: (1) The air-blowing comb-brush combination soil cleaning device, which combines rotating brushes and high-pressure airflow for soil cleaning, integrates the advantages of two types of soil cleaning mechanisms: contact type with high work efficiency and non-contact type with thorough soil cleaning without damaging the grapevines. It improves the work effect, has superior work performance compared to single soil cleaning mechanisms, and has excellent soil cleaning effect and high soil cleaning efficiency.

[0013] (2) The bristles are made of flexible and elastic material, and will not cause damage to the grapevines when they come into contact with them. At the same time, the centrifugal compressor blower continuously outputs a stable high-pressure and high-speed airflow. During the air blowing soil cleaning process, the bristles will not come into contact with the grapevines. The combination of the two soil cleaning devices can blow the soil that is tightly attached to the grapevines away from the soil ridge and expose the grapevines to the soil surface, which is convenient for manual vine lifting and trellising later. This effectively reduces the damage rate of grapevines in mechanized soil cleaning operations and improves the quality of soil cleaning. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] In a broad embodiment of this utility model, the air-blowing comb-brush combined grapevine frost-resistant soil removal device has the following structure: Figure 1 , Figure 2 As shown, it mainly includes: ground wheel component 1, front support frame 2, ground wheel outer sleeve 3, ground wheel welded steel plate 4, main frame 5, three-head gearbox 6, fan drive pulley I 7, belt 8, fan driven pulley I 9, intermediate rotating shaft 10, fan drive pulley II 11, left-hand centrifugal fan 12, fan square to round flange 13, airflow duct 14, brush driven pulley 15, tapered bearing dust cover 16, brush assembly 17, bearing box 18, fan driven pulley II 19, brush drive pulley 20.

[0018] The brush assembly 17 has the following structure: Figure 3 As shown, it includes a brush roller bottom cap 1701, brush bristles 1702, brush spacer 1703, inner constriction air nozzle 1704, brush roller 1705, brush roller end cap 1706, brush roller connecting end 1707, brush upper end connecting shaft 1708, and airflow main pipe 1709.

[0019] Specifically, the soil cleaning brush assembly 17 is cylindrical in shape, with a diameter of 550mm and a height of 400mm. It operates vertically, therefore removing less soil from the upper part than the lower part. Simultaneously, the soil compaction at the bottom of the ridge is greater than in the middle and upper parts, so the force on the soil cleaning brush assembly increases progressively from top to bottom. The soil cleaning brush assembly 17 consists of densely packed brush bristles 1702, specifically, the effective length of the bristles 1702 is 150mm, and the effective height is 345mm.

[0020] The bristles 1702 are connected to the brush roller 1705. The brush roller 1705 drives the bristles 1702 to rotate, combing the soil. At the same time, the left-hand centrifugal fan 12 outputs airflow, which is transmitted through the airflow duct 14 to the inward-reducing air nozzle 1704 to blow the soil with air. This achieves the combined air-blowing and combing method for removing frost-resistant soil from grapevines by using a rotating brush and high-pressure airflow.

[0021] The power of the brush roller 1705 comes from the rear output shaft (PTO) of the tractor. Specifically, the power of the rear output shaft (PTO) of the tractor is transmitted to the brush roller 1705 through the three-head gearbox 6, the brush drive pulley 20, the belt 8, the brush driven pulley 15, the upper end connecting shaft 1708 of the brush, and the brush roller connecting end 1707.

[0022] The power of the left-hand centrifugal fan 12 comes from the rear output shaft (PTO) of the tractor. Specifically, the power of the tractor rear output shaft (PTO) is transmitted to the left-hand centrifugal fan 12 through the three-head gearbox 6, the fan drive pulley I 7, the belt 8, the fan driven pulley I 9, the intermediate rotating shaft 10, the fan drive pulley II 11, the belt 8, the fan driven pulley II 19, and the bearing box 18.

[0023] The input shaft of the three-head gearbox 6 is directly connected to the rear output shaft (PTO) of the tractor. The power of the output shaft is divided into two paths: one path is connected to the blower drive pulley I7 through the rear output shaft, and the other path is connected to the brush drive pulley 20 through the lower output shaft. Its structure is as follows. Figure 4 As shown, the gearbox support plate 0503 is bolted to the main frame 5.

[0024] The fan drive pulley I7 forms a belt drive with the fan driven pulley I9 via belt 8 for speed increase. Specifically, in the belt drive, the rotational speed of the drive pulley and the driven pulley is inversely proportional to their diameter. Therefore, ignoring energy loss and slippage, the transmission ratio is 3.125.

[0025] The driven pulley I9 of the fan is connected to the intermediate rotating shaft 10, and transmits power to the driving pulley II11 of the fan.

[0026] Specifically, the type, size, installation height, and other parameters of the fan drive pulley I7 and the fan drive pulley II11 are the same, and the diameter of the main drive pulley is D1, which ranges from 100 to 400 mm. Preferably, in this embodiment, D1 = 250 mm.

[0027] The number of belts 8 on each main drive pulley is the same, but the lengths are different. The belts on the side closer to the centrifugal compressor 12 are shorter, with a length of 1275.5 mm.

[0028] Specifically, the number of belts 2 on each main drive belt 4 is m. To ensure the effectiveness of power transmission, the value of m ranges from 2 to 10. Preferably, in this embodiment, m=3.

[0029] The fan drive pulley II11 forms a belt drive with the fan driven pulley II19 via belt 8 for speed increase. Specifically, in the belt drive, the rotational speed of the drive pulley and the driven pulley is inversely proportional to their diameter. Therefore, ignoring energy loss and slippage, the transmission ratio is 3.125.

[0030] The driven pulley II19 of the fan is connected to the bearing housing 18, and the bearing housing 18 is fixed to the main frame 5 by bolts to the bearing housing bracket 0508.

[0031] Specifically, the driven pulley I9 and driven pulley II19 of the fan are identical in type, size, installation height, and other parameters. The diameter of the driven pulley is D2, which ranges from 40 to 340 mm. It should be noted that the diameter D2 of the driven pulley must be smaller than the diameter D1 of the main drive pulley, i.e., D2 < D1. Preferably, in this embodiment, D2 = 80 mm.

[0032] The bearing housing 18 connects the driven pulley II 19 of the fan to the left-hand centrifugal fan 12, and the left-hand centrifugal fan 12 is connected to the fan square to round flange 13 by bolts.

[0033] The fan's square-to-round flange 13 connects to the airflow duct 14 to transport airflow. The airflow duct 14 is connected to the main airflow pipe 1709 via a flange interface. The flange interface 1709 is fixed to the air pipe support plate 0509 with bolts. The air pipe support plate 0509 is fixed to the main frame 5 with bolts. Its structure is as follows. Figure 5 As shown.

[0034] The brush drive pulley 20 is connected to the brush driven pulley 15 via belt 8 to form a belt drive for speed reduction.

[0035] Specifically, the diameter of the main drive pulley is d1, ranging from 100 to 400 mm. Preferably, in this embodiment, d1 = 100 mm. The diameter of the driven pulley is d2, ranging from 40 to 340 mm. It should be noted that the diameter of the driven pulley must be smaller than the diameter of the main drive pulley, d2, i.e., d1 < d2. Preferably, in this embodiment, d2 = 125 mm. In belt drives, the rotational speeds of the driving and driven pulleys are inversely proportional to their diameters. Therefore, neglecting energy loss and slippage, the transmission ratio is 3.125.

[0036] The brush is connected to the upper connecting shaft 1708 of the brush via a drive pulley 20. The upper connecting shaft 1708 of the brush is equipped with a tapered roller bearing to support the rotation of the driven pulley shaft. It is mounted on the bearing bracket plate 0510. The lower end is connected to the brush roller connecting end 1707 by bolts. The tapered roller bearing dust cover 16 protects the tapered roller bearing and increases the bearing's efficiency and lifespan.

[0037] like Figure 6 As shown, the main frame 5 serves as the mounting carrier for all machine components. Its front end features a three-point suspension for attachment to a tractor. The main frame 5 includes a main frame 0501, two lower three-point suspension lugs 0502 fixedly mounted on the main frame 0501, a three-point suspension rod 0504 fixedly mounted on the upper part of the two lower three-point suspension lugs 0502, and an upper three-point suspension lug 0505 located at the upper center of the three-point suspension rod 0504. The upper three-point suspension lug 0505 is connected to the rear three-point suspension lug 0507 via a tie rod 0506, and the rear three-point suspension lug 0507 is fixedly mounted on the main frame 0501.

[0038] The main frame 0501 is also fixedly equipped with a three-head gearbox bracket 0503, a bearing box bracket 0508, an air pipe bracket 0509, and a bearing bracket 0510.

[0039] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the essence and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
