technical field

The invention relates to the technical field of orchard harvesting machinery, in particular to a detachable fruit collecting device.

Background technique

Harvesting in orchards is characterized by high labor intensity and strong seasonality. At present, domestic harvesting technology is still at the level of manual picking and picking. The disadvantages of manual harvesting are obvious. The labor cost of fruit farmers is high, the labor force is insufficient, the picking efficiency is low, and it is easy to cause fruit damage, which is not conducive to storage. Although mechanical harvesting has been adopted regardless of the orchard, the use and promotion of harvesting machinery has been restricted to a certain extent due to factors such as terrain and fruit tree spacing, and the impact on fruit collection is particularly prominent.

Therefore, with the development of market demand, the collection method relying on manual picking can no longer meet the requirements of current productivity, and there is an urgent need for a collection device that is easy to operate, easy to carry, and has high work efficiency. According to the retrieval of patent literature, the fruit collection devices that have been developed in China at present include:

Detailed ways

Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

A detachable fruit collection device as shown in Fig. 1, Fig. 2 and Fig. 3, including a frame 8 equipped with traveling wheels 10 to drive the whole device to move, and a collection mechanism fixed at the bottom of the frame 8 to collect fallen fruits And two groups of deployment mechanisms that are installed symmetrically on both sides of the frame 8 and are inverted umbrella-shaped around the device periphery after deployment.

The frame 8 includes a traveling wheel 10 installed at the front end, a drawbar 4 and a support rod 6 welded at the rear end, and five sets of bushings 7 are welded on both sides of the line of symmetry, one of which is welded at the front end of the frame in an arc-shaped on the pole for mounting the support pole. The front end of the frame is in the shape of a fan-shaped opening for guiding the trunk to the geometric center of the fruit collection tarpaulin.

Described collection mechanism comprises the fruit collection box support 11 that is welded on the frame bottom and some fruit collection boxes 9 that drop fruit is packed, and fruit collection box is placed on the fruit collection box support.

Two sets of deployment mechanisms have the same structure and are symmetrically installed on both sides of the frame; The fruit that is connected on the support rod collects tarpaulin 5. The support rods are respectively connected with the bushings correspondingly and protrude outwards. The support rods can rotate along the axis of the bushings. In the non-working state, the support rods are turned to the rear end of the frame. Expand in a ring.

As shown in Figure 4, the front support rod is a folding rod. When the tarpaulin is unfolded, the upper end of the front support rod is located on the symmetrical plane of the collection mechanism, so as to ensure that the front sides of the two sets of unfolding mechanisms are closed without opening. As shown in Fig. 5 and Fig. 6, the three middle support rods and the rear support rods are straight rods. In this example, when the fruit collection tarpaulin is folded, the three middle support rods and the rear support rods are parallel to each other.

After the two sets of deployment mechanisms are deployed, the tarpaulin acts as a collection surface and wraps around the outside of the device in an inverted umbrella shape. When working, the geometric center of the support bar does not coincide with the material outlet on the fruit collection tarpaulin, and the fruit collection tarpaulin is suspended on the support bar to avoid falling fruit from hitting the support bar.

As shown in Figure 9, the upper edge of the fruit collection tarpaulin is expanded into a polygon, and the diameter of the circumscribed circle of the polygon is 2 to 10 meters; The support rods are connected by hooks; the front end of the fruit collection tarpaulin is sewn with a covering tarpaulin to avoid fruit leakage. The shielding tarpaulin is in the shape of a cuboid, and the interior of the shielding tarpaulin is filled with sponge. Fruit collection tarpaulin A buffer tarpaulin is sewn at the fruit drop outlet to reduce fruit drop damage.

Working process and principle of the present invention are as follows:

During operation, the device is moved under the fruit tree to be picked, and the device is clamped and fixed on the trunk of the fruit tree through the arc rod at the front end of the frame. Manually only need to pull the front support rod to drive the fruit collection tarpaulin centered on the tree trunk, unfolding from the front to the back of the frame in an inverted umbrella shape, the upper edge of the fruit collection tarpaulin unfolds into a polygon, and the diameter of the circumscribed circle of the polygon is 2~10 m, thereby enclosing the entire trunk of the fruit tree. The front end of the fruit collection tarpaulin surrounding the trunk is sewn with a shelter tarpaulin to avoid fruit leakage. The shaken fruit falls on the fruit collection tarpaulin, and rolls down along the inclined fruit collection tarpaulin to the material outlet of the fruit collection tarpaulin. A buffer tarpaulin is sewn at the outlet to reduce fruit damage. The fallen fruit falls into the fruit collection box under the action of gravity. After the fruit is full, the fruit collection box is replaced to complete the fruit collection work.

Finally, it should be noted that what is listed above are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All deformations that can be directly derived or associated by those skilled in the art from the content disclosed in the present invention should be considered as the protection scope of the present invention.
