Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment for picking small-grain coffee, and in particular relates to a small-grain coffee picking machine. Background Art

[0002] Arabica coffee, commonly known as coffee beans, has smaller berries than cane coffee and large coffee. The berries are oval and typically contain two seeds. When the berries ripen on the Arabica coffee plant, mechanical equipment is generally used to reduce the labor intensity of picking. A picker is a type of mechanical picking equipment used to pick Arabica coffee. There are many types of pickers. One type of picker uses a mechanical arm to vibrate the Arabica coffee plant, causing the ripe, easily detachable berries to fall off during the high-frequency shaking. The fallen Arabica coffee berries land on a soft, manually spread tarpaulin. As the tarpaulin is rolled up, the berries fall onto a conveyor belt, which then transports them to a collection bin.

[0003] When the harvester is picking, the tarpaulin is spread out on both sides of the Arabica coffee trees. The berries from the shaking trees fall onto the tarpaulin. Although the tarpaulin is relatively soft and generally does not damage the fallen berries, as the berries accumulate on the tarpaulin, the accumulated berries gather together and cause the tarpaulin to dent. The fallen berries fall into the dented area and collide with the accumulated berries, which increases the damage to the berries. The spread tarpaulin is not designed to cushion the berries.

[0004] The existing picking machine has the problem that there is no design to cushion the small-grain coffee berries on the unfolded oilcloth when in use. Therefore, the present application proposes a small-grain coffee picking machine. Utility Model Content

The winding roller 14 is operated to rotate and the receiving oilcloth 15 is wound, and the coffee fruits falling on the receiving oilcloth 15 are picked. The coffee berries fall onto the conveyor belt 12, which transports the coffee berries to complete the picking process. The principle and method of picking by the picking machine body are conventional technical means, which will not be described in detail in this application; the support member includes an end rod 21 that passes through one side of the receiving oilcloth 15, a connecting member 22 that is rotatably sleeved on the end of the end rod 21, and an adjusting rod 23 that is rotatably connected to the end of the connecting member 22. The connecting member 22 connects the end rod 21 and the adjusting rod 23, so that there is a distance between the end rod 21 and the adjusting rod 23, and the position of the adjusting rod 23 can be changed; the buffer member includes a fixing ring 31 that is rotatably sleeved on the outside of the adjusting rod 23. , a first connecting rod 33 connected to the outer surface of the fixing ring 31 at one end, a second connecting rod 32 connected to the other end of the first connecting rod 33, and a buffer oil cloth 4 installed between the symmetrically distributed first connecting rods 33, the fixing ring 31 and the adjusting rod 23 are screwed together, the first connecting rod 33 and the fixing ring 31 and the second connecting rod 32 are screwed together, and the buffer oil cloth 4 covers part of the receiving oil cloth 15, so that the fallen coffee berries first fall on the buffer oil cloth 4, and then the coffee berries slide from the bottom of the buffer oil cloth 4 and fall onto the receiving oil cloth 15 and accumulate, which can prevent the subsequent fallen coffee berries from accumulating with the pile. The accumulated coffee fruits directly contact and collide with each other, resulting in damage. A discharge chute 41 is provided on the side surface of the buffer oilcloth 4 near the second connecting rod 32, and the fallen coffee fruits slide on the buffer oilcloth 4 and slide out of the discharge chute 41; the end of the pressure rod 5 is connected to the outer surface of the adjusting rod 23, and the pressure rod 5 is screwed together with the adjusting rod 23 by a screw. The pressure rod 5 can press against the receiving oilcloth 15 to form a depression in the receiving oilcloth 15, which is conducive to the accumulation of coffee fruits, or the pressure rod 5 is frequently rotated, and the pressure rod 5 shakes the receiving oilcloth 15, so that the coffee fruits accumulated on the receiving oilcloth 15 are in a loose state.

[0027] In this embodiment, the connecting member 22 includes a first swivel rotatably mounted on the outside of the end rod 21, a second swivel rotatably mounted on the outside of the adjusting rod 23, and a connecting rod installed between the first swivel and the second swivel. The end rod 21 and the adjusting rod 23 are parallel. The connecting member 22 connects the end rod 21 and the adjusting rod 23 so that there is a distance between the end rod 21 and the adjusting rod 23, and the position of the adjusting rod 23 can be changed.

[0028] In this embodiment, a “U”-shaped gripping rod 34 is provided between the symmetrical fixing rings 31 , and the positions of the first connecting rod 33 and the second connecting rod 32 can be conveniently changed through the gripping rod 34 .

[0029] In this embodiment, a trapezoidal material receiving area is formed between the adjusting rod 23, the second connecting rod 32 and the first connecting rod 33. The buffer oilcloth 4 is located in the material receiving area. The buffer oilcloth 4 covers part of the receiving oilcloth 15, so that the fallen coffee fruits first fall on the buffer oilcloth 4, and then the coffee fruits slide from the bottom of the buffer oilcloth 4 to the receiving oilcloth 15 and accumulate. This can prevent the subsequent fallen coffee fruits from directly contacting and colliding with the accumulated fruits, resulting in damage. A leakage groove 42 is opened on the surface of the buffer oilcloth 4, which is conducive to the coffee fruits falling from the leakage groove 42.

[0030] In this embodiment, the pressing rod 5 is a "U"-shaped rod structure with bent ends. The outer surface of the pressing rod 5 is tangent to the receiving oilcloth 15.

[0031] In this embodiment, the adjusting rod 23 rotates along the direction a and the pressing rod 5 presses the receiving oilcloth 15. The part of the receiving oilcloth 15 that contacts the pressing rod 5 is concave to form a shaking groove B, which is conducive to the accumulation of coffee fruits in the shaking groove B. The second connecting rod 32 and the first connecting rod 33 rotate along the direction b, and a gap H is formed between the second connecting rod 32 and the receiving oilcloth 15. The size of the gap H can be manually adjusted according to actual conditions. There is a distance between the second connecting rod 32 and the receiving oilcloth 15, which does not affect the coffee fruits on the receiving oilcloth 15 rolling onto the conveyor belt 12.

[0032] The working principle and use process of this utility model:

[0033] When picking small-grain coffee cherries, a receiving tarpaulin 15 is manually unfolded and distributed on both sides of the coffee plantation. The mechanical clamp arm 13 is operated to clamp and shake the coffee plantation, and the ripe and easily falling coffee cherries fall onto the receiving tarpaulin 15. The winding roller 14 is operated to rotate and the receiving tarpaulin 15 is wound up. The coffee cherries picked and dropped from the receiving tarpaulin 15 fall onto the conveyor belt 12, which transports the coffee cherries to complete the picking process.

[0034] When the manually unfolded receiving oilcloth 15 receives the small-grain coffee cherries, the buffer oilcloth 4 covers a portion of the receiving oilcloth 15, so that the fallen coffee cherries fall onto the buffer oilcloth 4 first;

[0035] The coffee cherries then slide down the bottom of the buffer tarpaulin 4 and fall onto the receiving tarpaulin 15, where they are piled up. The coffee cherries also fall through the trough 42, which prevents subsequent falling coffee cherries from directly contacting and colliding with the piled cherries and causing damage.

[0036] The pressing rod 5 rotates and presses against the receiving oil cloth 15, causing the receiving oil cloth 15 to form a depression, which is conducive to the accumulation of coffee cherries;

[0037] Alternatively, the pressing rod 5 is rotated frequently to shake the receiving oil cloth 15, thereby loosening the coffee cherries accumulated on the receiving oil cloth 15;

[0038] In summary: In the present application, there is no design for buffering small-grain coffee berries on the unfolded oilcloth. The buffer oilcloth 4 covers part of the receiving oilcloth 15, so that the fallen coffee berries first fall on the buffer oilcloth 4, and the coffee berries slide from the bottom of the buffer oilcloth 4 to the receiving oilcloth 15 and accumulate, which can prevent the subsequent falling coffee berries from directly contacting and colliding with the accumulated berries and causing damage.

[0039] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
