Roads with a width greater than the width of the rollers will cause the fallen fruits on both sides of the road to be unable to be collected, and the device needs to be moved back and forth to collect the fruits. In addition, when encountering complex forest roads, the protruding road surface can easily damage the stirring rods on the rollers, and the fruits falling on the concave ground surface cannot be in contact with the rollers, so they cannot be collected. Therefore, the use effect is limited.

By making the adjacent two cleaning assemblies 43 have the included angle, the included angle between the cleaning assembly 43 first contacting the ground and the adjacent cleaning assembly 431 can continuously decrease after the cleaning assembly 431 first contacting the ground is extruded and deformed by the ground, so that the ground swept by the gathering frame 4 can continuously be pushed by the multiple cleaning assemblies 43, and the included angle between the cleaning assembly 431 first contacting the ground and the adjacent cleaning assembly 431 can not gradually increase when the rotating shaft 42 rotates, so that the fallen fruits can not leak out from the included angle between the two cleaning assemblies 43.

[0057] When the utility model is used, the fixed frame 2 is fixed at the front end of a tractor or other agricultural vehicle, the extension and retraction of the first hydraulic rod 333 and the second hydraulic rod 45 and the rotation of the hydraulic motor 441 are controlled through the multi-way reversing valve 21 on the fixed frame 2, the hydraulic motor 441 is closed when driving in a non-working mode, the first hydraulic rod 333 is retracted through the multi-way reversing valve 21, the first hydraulic rod 333 pulls the tension beam 332 to rotate around the second support 222, and the end of the tension beam 332 away from the second support 222 drives the lifting frame 3 to lift upward, the upper part of the lifting frame 3 is connected with the first support 221 on the upper part of the fixed frame 2 through the connecting rod 331, so that the first hydraulic rod 333 is retracted, and the length of the first hydraulic rod 333 is reduced, the lifting frame 3 is pulled by the first hydraulic rod 333 to translate and rise upward, and further drives the gathering frame 4 connected with the lifting frame 3 to translate and rise upward, so that the cleaning assembly 43 at the lowermost part of the gathering frame 4 is away from the ground, and the service life of the cleaning assembly 43 is prevented from being shortened due to friction with the ground; when the non-working road section is narrow, the second hydraulic rod 45 is controlled to extend through the multi-way reversing valve 21, the second hydraulic rod 45 drives the gathering frame 4 to rotate around the cross shaft 314 on the sixth support 313, and the gathering frame 4 is driven to rotate around the cross shaft 314 on the sixth support 313 through the second hydraulic rod 45, so that the distance between the ends of the two gathering frames 4 away from the lifting frame 3 is reduced, and the gathering frame 4 can drive the fallen fruits to gather to the lifting frame 3. Figure 3 As shown, when the two gathering frames 4 rotate to gradually reduce the included angle, the distance between the ends of the two gathering frames 4 away from the lifting frame 3 is also reduced, so that the gathering frame 4 can drive the fallen fruits to gather to the lifting frame 3.

[0058] Embodiment 3

[0059] The fruit of the forest tree that needs to be collected is first shaken or sprayed with a pesticide to make the fruit fall on the ground in the forest. When the collection of the fallen fruit in the forest begins, the first hydraulic rod 333 is extended by the multi-way reversing valve 21, and the lifting frame 3 is translated downward under the action of the pushing of the first hydraulic rod 333 and the gravity of the gathering frame 4, until the cleaning part 431 at the bottom of the gathering frame 4 contacts the ground, and then the first hydraulic rod 333 stops extending, so as to ensure that the cleaning assembly 43 can always contact the ground when rotating; then, according to the width of the road between the rows of forest trees, the second hydraulic rod 45 is controlled to contract by the multi-way reversing valve 21, and when the second hydraulic rod 45 contracts, the gathering frame 4 is pulled to rotate around the cross shaft 314 on the sixth support 313 in a direction away from the other gathering frame 4, until the end of the gathering frame 4 away from the lifting frame 3 approaches the two sides of the forest trees, and then stops, so as to avoid collision between the gathering frame 4 and the trees on both sides of the road when walking forward; then, the hydraulic motor 441 is started by the multi-way reversing valve 21, the hydraulic motor 441 drives the driving wheel 442 to rotate, the driving wheel 442 drives the transmission wheel 444 to rotate through the transmission part 443, the transmission wheel 444 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives all the cleaning assemblies 43 to rotate synchronously, so that all the cleaning assemblies 43 contacting the ground push the fallen fruit on the ground to the direction between the two gathering frames 4, and the fruit fallen on the road between the rows of forest trees is concentrated in the middle of the road by the walking of the driving mechanism 1, so as to prevent the fruit from being crushed by the driving mechanism 1 when walking, and facilitate the concentrated picking of the picking mechanism behind.

[0062] Embodiment 5

[0063] The two lifting frames 3 and the two converging frames 4 are symmetrically arranged on the left and right sides, and the up-down movement of the lifting frame 3 or the left-right rotation of the converging frame 4 can also realize independent control on both sides, so that the single-side lifting frame 3 is lifted up, as shown in the accompanying drawings Figure 7 and Figure 8 When a single-side ground exists a continuous protrusion, the first hydraulic rod 333 on the side is controlled to retract, the lifting frame 3 on the side is lifted up, the converging frame 4 connected with the lifting frame 3 is lifted off the ground, and only the cleaning assembly 43 on the single-side converging frame 4 can be used to collect fruits; when a curved road section is encountered, the extension and retraction of the two second hydraulic rods 45 are independently controlled, the angle of the single-side converging frame 4 can be changed, the turning radius is reduced, and the continuous collection of forest fruits during turning is not affected; and the extension and retraction lengths of the two second hydraulic rods 45 are simultaneously controlled, the opening and closing angle between the two converging frames 4 is controlled through the pushing force or the pulling force of the second hydraulic rod 45, the forest fruits fallen on the road between the trees are pushed to the road above the two converging frames 4 by the cleaning assembly 43 below the two converging frames 4, and the rear picking device is convenient for centralized picking.
