Specific embodiments

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] As Figures 1 - 5 shown, an embodiment of the present invention provides a pneumatic type small fruit and tree picking and collecting vehicle for ground use. A pneumatic type small fruit and tree picking and collecting vehicle for ground use includes a mobile trolley, a collection box 2, a suction chamber 5, a fan 4, a feed pipe 7, and a gasoline engine 3;

[0030] The collection box 2 is installed on the mobile trolley for storing forest fruits. The top of the collection box 2 is provided with a feed inlet. The suction chamber 5 is installed on the collection box 2. The suction chamber 5 has a suction cavity. The suction chamber 5 is provided with a first opening, a second opening and a discharge port communicating with the suction cavity. The discharge port is located at the bottom of the suction cavity and is lower than the first opening. The discharge port of the suction chamber 5 is higher than the feed inlet of the collection box 2, and the discharge port of the suction chamber 5 is communicated with the feed inlet of the collection box 2;

[0031] The air inlet of the fan 4 is communicated with the second opening. The fan 4 is used to extract the air in the suction cavity to make the suction cavity in a negative pressure state. At least one filter element is installed in the second opening. The filter element is used to intercept objects to prevent objects from entering the fan 4. One end of the feed pipe 7 is communicated with the first opening; The output shaft of the gasoline engine 3 is connected to the impeller of the fan 4 to drive the impeller to rotate.

[0032] In this embodiment, when the forest fruits fall onto the collection umbrella or the collection film and need to be collected, the pneumatic small-sized forest fruit picking and collecting vehicle can be pushed close to the collection umbrella or the collection film at this time. Then the operator holds the feed pipe 7 and aims it at the forest fruits on the collection umbrella or the collection film. At the same time, the control switch 301 on the gasoline engine 3 is turned on. The output shaft of the gasoline engine 3 drives the impeller of the fan 4 to rotate. The fan 4 extracts the air in the suction chamber 5 to form a negative pressure in the suction chamber 5. Under this negative pressure state, small-sized forest fruits such as camellia oleifera fruits, seabuckthorn fruits, and wild jujube fruits on the collection umbrella or the collection film are extracted into the feed pipe 7 and then enter the suction chamber 5 along the feed pipe 7. Since the first opening in the suction chamber 5 is higher than the discharge port, the forest fruits entering from the first opening fall into the discharge port under the action of gravity, and thus enter the feed inlet of the collection box 2 along the discharge port and are finally collected by the collection box 2. Subsequently, the operator continuously adjusts the position of the feed pipe 7 to collect the remaining fruits until all the fruits on the collection umbrella or the collection film are collected. After the fruits on the collection umbrella or the collection film are picked and collected, the pneumatic small-sized forest fruit picking and collecting vehicle can be pushed to the next working location for picking work.

[0033] It should be noted that since a filter element is installed in the second opening of the suction chamber 5, the filter element plays an interception role to prevent branches, leaves, fruits, etc. from being sucked into the fan 4.

[0034] It can be seen that the pneumatic small-sized forest fruit picking and collecting vehicle in this embodiment can be used in cooperation with the collection film or the collection umbrella to quickly collect the fruits in the collection film or the collection umbrella. There is no need to manually collect the forest fruits on the collection umbrella or the collection film together, which reduces the labor intensity. Moreover, the air suction method is used to pick the forest fruits, which can reduce the damage of the forest fruits during the picking and collecting process and improve the finished product rate of the forest fruits.

[0035] It should be specifically noted that this pneumatic small-scale fruit and forest product picking and collecting vehicle can also collect fruits and forest products independently, and has the characteristics of high flexibility, convenient use and easy operation.

[0036] As a preferred embodiment, as Figure 4 and Figure 5 shown, the suction chamber 5 includes a connected box body 501 and a cylinder body 502. The cylinder body 502 is cylindrical, one end of which has an opening, and this opening constitutes the second opening of the above-mentioned suction chamber 5, and the other end is sealed. The inside of the box body 501 has a cavity, and this cavity constitutes a suction cavity. An opening is respectively provided on two opposite side surfaces of the box body 501, one of the openings constitutes the above-mentioned first opening, and the other opening of the box body 501 is connected to the sealed end of the cylinder body 502. Further, an opening is provided on the lower surface of the box body 501, and this opening constitutes the above-mentioned discharge port.

[0037] As Figure 4 shown, a discharge pipe 6 is hermetically installed at the feed port on the top of the collection box 2.

One end of the feed pipe 7 is connected to the first opening on one side of the box body 501, and the second opening on the cylinder body 502 is connected to the fan 4.

[0038] In this way, after the fan 4 is started, the fan 4 extracts the air in the suction cavity of the box body 501, making the suction cavity in a negative pressure state, so that the fruits enter the suction cavity from the first opening on the box body 501 along the feed pipe 7. Under the action of gravity, the fruits in the suction cavity sequentially pass through the discharge port at the bottom of the box body 501, the discharge pipe 6 and the feed port at the top of the collection box 2 and then enter the collection box 2.

[0039] It should be noted that in this embodiment, the feed pipe 7 includes a connected hose and a picking pipe 701. Among them, one end of the hose is connected to the first opening on the box body 501, and the other end is connected to the picking pipe 701.

Since the hose itself has good flexibility and toughness and is not easy to break and harden, this enables the hose to adapt to various complex environments.

[0040] Further, the picking pipe 701 and the hose are detachably connected through a pipe connector, such as using a clamp connection, to facilitate the replacement of picking pipes 701 of different sizes. When the collected fruits are relatively large, the small-sized picking pipe 701 can be detached and replaced with a large-sized picking pipe 701.

[0041] As a preferred embodiment, as Figure 4As shown, a filter is coaxially arranged on the inner wall of the cylinder 502, and the preferred filter is a filter screen 9. The function of the filter screen 9 is to prevent branches, leaves, fruits, etc. from being sucked into the fan 4 to cause damage to the fan 4.

[0042] Preferably, Figure 1 and Figure 2 As shown, the gasoline engine 3 and the fan 4 are installed on the top of the vehicle body 1, the fan 4 includes a fan cover, and the fan impeller is installed in the fan cover. The function of the fan cover is to prevent people or objects from being drawn into the fan and causing unnecessary damage or loss. Furthermore, an air outlet 401 is provided on the fan cover to exhaust gas when the fan is working. The output shaft of the gasoline engine 3 is connected to the impeller of the fan 4, and the impeller of the fan 4 is driven to rotate by the gasoline engine 3, so as to draw air in the suction chamber 5 and discharge it through the air outlet 401 on the side of the fan 4.

[0043] As a preferred embodiment, Figure 1 and Figure 2 As shown, a discharge port is provided on the right side of the collection box 2, and a box door 201 is hingedly installed in the discharge port. The box door 201 is fixed by a latch, and a handle is also installed on the box door 201. When the fruits fill the inner space of the collection box 2, the latch can be pulled out and the box door 201 can be opened to take out the collected fruits.

[0044] It should be noted that the specific form of the mobile vehicle is not specifically limited, as long as it can be flexibly moved. In this embodiment, the mobile vehicle includes a vehicle body 1 and a wheel mechanism installed on the chassis of the vehicle body 1, and the vehicle mechanism includes four wheels 101. Among them, the diameter of the wheel 101 can be adjusted according to the geographical conditions. For example, when working in gravel, sandy land, hilly and overgrown land, the diameter of the wheel 101 can be appropriately increased.

[0045] As a preferred embodiment, Figure 1 , Figure 2 and Figure 3 As shown, in order to facilitate pushing the moving trolley, a handle 8 is installed on the vehicle body 1, and the handle 8 is installed on the moving trolley.

[0046] In order to adapt to people of different heights, the handle 8 in this embodiment can be adjusted in length and height according to the needs of the user. Specifically, the handle 8 includes two arc tubes and a U-shaped tube, wherein the arc tube includes an arc section and a straight tube section connected to each other, the bottom ends of the arc sections of the two arc tubes are fixed on the vehicle body 1, and the straight tube sections of the two arc tubes point to the side away from the feed tube 7. A plurality of first screw holes are evenly opened on the straight tube section of the arc tube along its length direction. A plurality of second screw holes are respectively opened at both ends of the U-shaped tube, and the diameter of the U-shaped tube is slightly smaller than the diameter of the arc tube.

[0047] Both ends of the U-shaped tube are respectively inserted into the straight pipe sections of the two arc-shaped tubes, and then the depth of the U-shaped tube inserted into the straight pipe section is adjusted to adjust the exposed length and height of the U-shaped tube. After the position of the U-shaped tube is adjusted, the U-shaped tube is finely adjusted so that the second screw hole on the U-shaped tube is aligned with the first screw hole on the straight pipe section of the arc-shaped tube, and finally it can be fixed with bolts.

[0048] In summary, compared with the traditional manual picking method, using the pneumatic floor-type small fruit and forest picking and collecting vehicle of the present invention effectively improves the production efficiency, reduces the labor cost and labor intensity, and since there is no direct contact with the fruits and forests during operation, it avoids the damage of fruits caused by direct touch and improves the finished fruit rate.
