Description

Technical Field

[0001] This utility model relates to agricultural picking machinery, specifically to a self-propelled suction picking machine. Background Technology

[0002] Suction-type harvesters are devices that use the suction force generated by a fan to pick up crops. Existing suction-type harvesters, to ensure sufficient suction, have relatively small pickup openings and are mostly mounted structures, requiring the use of a towing vehicle. Chinese utility model patent CN202322765544.4 discloses an auxiliary device for a stevia harvester, which uses a fan to harvest stevia. However, the conveying pipe in this patent is a straight cylinder, requiring a high-powered fan. The small pickup opening limits the coverage width of a single pickup, making it unsuitable for crops such as chili peppers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a suction-type self-propelled picking machine, which is suitable for picking and collecting various crops such as chili peppers.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a suction-type self-propelled pickup machine, including a vehicle body and a suction-type pickup device installed on the vehicle body. The suction-type pickup device includes a pickup, a fan housing, and a fan. The fan housing is provided with an air inlet and an air outlet. The pickup is connected to the air inlet of the fan housing. The pickup opening of the pickup is a flat opening along the width direction of the vehicle body. The fan is installed inside the fan housing and blows the material sucked into the fan housing from the pickup opening out of the air outlet. The pickup opening of the pickup is set as a flat opening along the width direction of the vehicle body, which helps to increase the pickup coverage area and improve the pickup efficiency.

[0005] As an optional embodiment of this invention, the pickup is a hollow cylinder with a pickup port and a connection port at its two ends. From the pickup port towards the connection port, the width of the pickup's inner cavity gradually decreases while its height gradually increases. The pickup's inner cavity has an irregular shape, which not only concentrates airflow and increases the intensity of crop absorption from the pickup port towards the connection port, but also ensures smooth crop transport and prevents blockage within the pickup cavity.

[0006] As an optional solution of this utility model, a pressure roller is also provided on the pickup device below the pickup port, and the pressure roller is arranged along the width direction of the vehicle body.

[0007] As an optional solution of this utility model, the fan casing is provided with an installation port, which is located on opposite side walls of the casing, along with the air inlet. The fan includes a rotating shaft and an impeller. The rotating shaft passes through the installation port and is rotatably connected to the fan casing. The impeller is located inside the fan casing and connected to the rotating shaft. A suction baffle is provided between the impeller and the air inlet, with a feeding gap reserved between the suction baffle and the air inlet. A guide surface is provided inside the fan casing, which surrounds the impeller and connects to the discharge port. A discharge gap is reserved between the outer end of the impeller and the guide surface, and the discharge gap communicates with the feeding gap. After the crop is sucked into the fan casing, it falls from the feeding gap into the discharge gap due to the obstruction of the suction baffle. Then, under the action of the fan, the crop is blown out from the air outlet along the guide surface.

[0008] As an optional solution of this utility model, an engine is installed on the vehicle body, and the power output of the engine is coupled with the drive shaft. While the engine drives the vehicle body to move, it can also provide power to the suction and picking device.

[0009] As an optional solution of this utility model, the mounting port and the air inlet are positioned directly opposite each other, and the suction baffle is provided with mesh. The suction baffle is located between the air inlet and the impeller of the fan, preventing crops sucked into the fan casing from being pushed into the impeller.

[0010] As an optional solution of this utility model, the fan casing includes a guide plate, a discharge plate, and a first end plate and a second end plate arranged opposite each other. The air inlet is arranged on the first end plate, and the mounting port is arranged on the second end plate. Two discharge plates are arranged between the first end plate and the second end plate. Each discharge plate is connected to the first end plate and the second end plate, and the four of them form a rectangular air outlet. The guide plate is arranged between the first end plate and the second end plate and is connected to the first end plate and the second end plate. The guide plate is rolled around the impeller and its two ends are connected to the two discharge plates respectively. The inner end surface of the guide plate is a guide curved surface.

[0011] As an optional embodiment of this invention, a circular fan mounting area is provided on the second end plate, with the fan installed within the fan mounting area. Two discharge plates are respectively positioned above and to the side of the fan mounting area, forming a vertical discharge port at the upper side of the fan mounting area. The guide plate is spirally wound around the impeller, with one end tangent to the fan mounting area and connected to the discharge plate located above the fan mounting area, and the other end tangent to the discharge plate located to the side of the fan mounting area. The spiral winding of the guide plate provides better material guiding and effectively prevents blockage inside the fan casing.

[0012] As an optional solution of this utility model, the vehicle body is also equipped with a storage box, and the air outlet is connected to the storage box. The top plate and / or side plate of the storage box are provided with exhaust vents. The storage box is equipped with exhaust vents so that air can be discharged while receiving the picked-up crops.

[0013] As an optional solution of this utility model, a discharge pipe is provided on the fan casing, the discharge pipe is connected to the air outlet, the discharge pipe is bent and extends into the storage tank, and a reversing baffle is provided at the bend of the discharge pipe, and an exhaust hole is also provided on the reversing baffle.

[0014] Compared with the prior art, the advantages of this utility model are as follows: 1. The pickup opening of the pickup device is a flat opening along the width of the vehicle body, which can cover a wider range, allowing the suction pickup device to pick up crops over a larger area, effectively improving pickup efficiency; 2. The pickup device is a hollow cylinder, and the inner cavity of the pickup device has a shape that gradually changes from the pickup opening to the connection port. From the pickup opening to the connection port, the inner cavity of the pickup device narrows in width, which has a wind-gathering effect and enhances the suction power of the fan on the crops. 1. The height of the inner cavity of the pickup gradually increases, allowing crops to smoothly enter the fan casing through the connection port, avoiding blockage inside the pickup; 2. A feeding gap and a suction baffle are set between the fan impeller and the air inlet inside the fan casing, and a discharge gap is set on the outer circumference of the impeller. A guide surface is set at the discharge gap. After the crops enter the feeding gap, they are prevented from being sucked into the impeller by the suction baffle. After the crops enter the discharge gap from the feeding gap, they are blown out from the air outlet along the guide surface under the operation of the impeller, avoiding blockage inside the fan casing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1-5 A self-propelled suction-type picking machine includes a vehicle body 1 and a suction-picking device 2. The suction-picking device 2 is mounted on the vehicle body 1. The vehicle body 1 is a frame with a front / rear axle structure, wheels, and an engine, which is a prior art type. The vehicle body 1 can drive the suction-picking device 2 to move. During the movement of the vehicle body 1, the suction-picking device 2 can suction-pick various crops such as chili peppers.

[0024] The suction-collecting device 2 includes a collector 21, a fan housing 22, and a fan 23. The fan housing 22 is mounted on the vehicle body 1 and has an air inlet and an air outlet. The collector 21 communicates with the air inlet of the fan housing 22. The collection port 211 of the collector 21 is located at the front end of the vehicle body 1 and is a flat opening along the width direction of the vehicle body 1. The fan 23 is installed inside the fan housing 22. When the fan 23 is working, it draws air in through the air inlet and the inner cavity of the collector 21 from the collection port 211 and exhausts air to the air outlet. Crops near the collection port 211 are drawn into the fan housing 22 and finally blown out from the air outlet. Because the pickup opening 211 is set as a flat opening and is set along the width direction of the vehicle body 1, the pickup opening 211 can cover a wider range. Compared with the pickup machine with a small pickup opening 211 in the prior art, it can pick up a larger range in a single trip, thus improving the pickup efficiency.

[0025] Please see Figure 1 and Figure 3The pickup 21 is a hollow cylinder with a pickup port 211 and a connection port 212 at its two ends. Both the pickup port 211 and the connection port 212 communicate with the inner cavity of the pickup 21, and the connection port 212 communicates with the air inlet of the fan housing 22. The inner cavity of the pickup 21 has an irregular shape. From the pickup port 211 to the connection port 212, the width of the inner cavity of the pickup 21 gradually decreases while the height of the inner cavity gradually increases. The width of the inner cavity of the pickup 21 narrows from the pickup port 211 to the connection port 212, which gives the pickup 21 a wind-gathering effect, ensuring sufficient pickup strength while having a larger pickup width. The height of the inner cavity of the pickup 21 widens from the pickup port 211 to the connection port 212, which facilitates the suction of crops inside the pickup 21 to the connection port 212, and then into the fan housing 22 through the connection port 212.

[0026] Preferably, the pickup port 211 is rectangular or elliptical, and the connection port 212 is circular. The length of the long side of the pickup port 211 is greater than the inner diameter of the connection port 212, and the length of the short side of the pickup port 211 is less than the inner diameter of the connection port 212. In the direction from the pickup port 211 to the connection port 212, the cross-sectional shape of the inner cavity of the pickup device 21 gradually changes from rectangular or elliptical to circular, and the cross-sectional width of the inner cavity gradually decreases while the height gradually increases.

[0027] The fan housing 22 is mounted on the vehicle body 1, and the pickup 21 is tilted so that the pickup port 211 is positioned close to the ground. As an optional implementation, the connection port 212 of the pickup 21 is connected to the air inlet of the fan housing 22 via a pipe. The pickup 21 is mounted on the vehicle body 1 and can rotate up and down relative to the vehicle body 1. The vehicle body 1 is provided with a rotation drive mechanism, which is connected to the pickup 21. The height of the pickup port 211 is adjusted by driving the pickup 21 to rotate up and down.

[0028] In a preferred embodiment, a pressure roller 213 is provided on the pickup 21 below the pickup opening 211. The pressure roller 213 is connected to the pickup 21 through a structure such as a bearing seat, and the pressure roller 213 can rotate. The pressure roller 213 is arranged along the width direction of the vehicle body 1. During the pickup process, the pressure roller 213 can press down the seedlings below the pickup opening 211 to facilitate the pickup of crops.

[0029] Please see Figures 1-5The fan housing 22 has a mounting port for mounting the fan 23. The mounting port and air inlet are located on opposite side walls of the fan housing 22. The fan 23 includes a shaft and an impeller. The shaft passes through the mounting port and is connected to the fan housing 22 via bearings. The shaft can rotate relative to the fan housing 22. One end of the shaft extends outside the fan housing 22 and is used for transmission with the drive component of the fan 23. The drive component of the fan 23 can also be the engine of the vehicle body 1. The shaft and the power output end of the engine are driven by a belt or other transmission method. The other end of the shaft extends into the fan housing 22. The impeller is located inside the fan housing 22 and connected to the shaft. Rotation of the shaft drives the impeller to rotate. A suction baffle 24 is provided inside the fan casing 22 between the impeller and the air inlet. A feeding gap is reserved between the suction baffle 24 and the air inlet. A guide surface is also provided inside the fan casing 22. The guide surface is bent around the impeller and connected to the discharge port. A discharge gap is reserved between the outer end of the impeller and the guide surface. The discharge gap is connected to the feeding gap.

[0030] For details, please refer to Figures 3-5 The fan casing 22 includes a first end plate 221, a second end plate 222, a guide plate 223, and a discharge plate 224. The first end plate 221 and the second end plate 222 face each other. The air inlet is located on the first end plate 221, and the mounting port is located on the second end plate 222. The air inlet and the air outlet can be set completely opposite to each other, or they can be appropriately staggered so that the air inlet is within the area of ​​the corresponding impeller. There are two discharge plates 224, both positioned between the first end plate 221 and the second end plate 222. Each discharge plate 224 is perpendicularly connected to both the first and second end plates 221 and 222. The first end plate 221, the second end plate 222, and the two discharge plates 224 form a rectangular air outlet. A guide plate 223 is positioned between the first and second end plates 221 and 222, perpendicularly connected to both the first and second end plates 221 and 222. The guide plate 223 is coiled around the impeller, with its two ends connected to the two discharge plates 224 respectively. The inner end face of the guide plate 223 is a guide curved surface. After the crop picked up by the pickup 21 enters the fan housing 22 through the air inlet, it falls from the feeding gap into the discharge gap. Under the action of the fan 23, the crop is blown along the guide curved surface to the air outlet and finally blown out from the air outlet.

[0031] When the impeller is driven to rotate, air is drawn into the pickup 21 through the air inlet and blown out through the air outlet. The crop at the pickup port 211 is sucked into the pickup 21, passes through the inner cavity of the pickup 21, the feeding gap and the discharge gap in sequence, and is blown out from the air outlet. The suction baffle 24 is used to prevent the crop from being sucked into the impeller when it enters the fan housing 22. The suction baffle 24 is provided with several mesh holes, which not only prevents the crop from being sucked into the impeller, but also ensures that the fan 23 has sufficient suction force on the pickup 21.

[0032] As a further embodiment, a fan 23 mounting area is provided on the second end plate 222. The fan 23 mounting area is a circular area, and the mounting port is located at the center of the fan 23 mounting area. After the impeller is installed inside the fan housing 22, the entire impeller is within the range of the fan 23 mounting area. Two discharge plates 224 are located above and to the side of the fan 23 installation area, respectively. Both discharge plates 224 are vertically arranged, thus forming a vertical discharge port at the upper side of the fan 23 installation area. The guide plate 223 is vortex-shaped around the impeller. One end of the guide plate 223 is connected to the discharge plate 224 located above the fan 23 installation area and is tangent to the fan 23 installation area. The other end of the guide plate 223 is tangent to the discharge plate 224 located to the side of the fan 23 installation area. The guide surface gradually moves away from the fan 23 along the curling direction of the guide plate 223. This not only helps to leave more space in the discharge gap and avoid the crop from being blocked in the fan casing 22, but also helps to throw the crop to the air outlet along the guide surface in the discharge gap.

[0033] Please see Figure 1 and Figure 2 In some embodiments, the vehicle body 1 is also equipped with a storage box 3, which is used to store the collected crops. The air outlet of the blower casing 22 is connected to the storage box 3, and the collected crops are thrown into the storage box 3 for temporary storage. The top plate and / or side plate of the storage box 3 are provided with exhaust holes, which are used to exhaust the air blown by the blower 23.

[0034] Please see Figures 1-5 As a further implementation, a discharge pipe 25 is provided on the fan casing 22, which is connected to the air outlet. The crop blown out from the air outlet enters the storage tank 3 along the discharge pipe 25. A loading port is provided on the side of the storage tank 3. The discharge pipe 25 bends at the height corresponding to the loading port and extends into the storage tank 3. A reversing baffle is provided at the bend of the discharge pipe 25. The reversing baffle is inclined and also has an exhaust hole. The discharge pipe 25 is connected to the outside through the exhaust hole. The chili peppers that are discharged from the air outlet into the discharge pipe 25 are bounced to the bend of the discharge pipe 25 after hitting the inclined reversing baffle, and thus enter the storage tank 3.
