Description

Technical Field

[0001] This utility model relates to the technical field of fruit harvesting equipment, specifically a negative pressure harvesting device for coffee berries. Background Technology

[0002] Coffee beans refer to the fruit of the plant used to make coffee. Broadly speaking, there are two types of coffee beans in the world: Arabica and Robusta. The coffee fruit consists of two oval seeds facing each other. The side that connects is flat and called the flat bean. In coffee cultivation, the ripe coffee cherries need to be harvested.

[0003] When harvesting coffee cherries, workers typically operate harvesting devices to cut the stems off the cherries, which then fall into collection bags through a collection hopper. Because the coffee cherries are located in different positions on the tree, workers need to spend a lot of time finding the stems before they can be cut and harvested. This reduces the harvesting efficiency of the harvesting devices and increases the workload of the workers.

[0004] According to announcement number CN214508048U, a coffee cherry harvesting device belongs to the technical field of fruit harvesting equipment. The device includes a collection hopper, a collection bag, a feeding device, and a harvester. The collection bag is detachably connected to the bottom of the collection hopper, and a belt for securing the hopper is provided. A feeding device for driving coffee cherries to fall into the collection hopper is installed at the top of the hopper. The feeding device is connected to the harvester for picking the coffee cherries via a feeding pipe. This invention, by setting the harvester to cut off the stem connecting the coffee cherries directly without direct contact or pulling, avoids damage to the entire branch or the coffee cherries. The feeding device allows the coffee cherries to be directly driven into the collection hopper and into the collection bag during the harvesting process, eliminating the need to repeatedly stuff the coffee cherries into the collection bag. This greatly improves the harvesting efficiency of coffee cherries, saves time and labor, is easy to carry, and has high adaptability.

[0005] The coffee cherry harvesting device described above requires workers to spend a lot of time finding the stalks of the coffee cherries in different positions on the tree before they can be cut and harvested. This reduces the harvesting efficiency of the device and increases the workload of the workers. Therefore, we need to propose a negative pressure harvesting device for coffee cherries.

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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a negative pressure harvesting device for coffee berries, including a harvesting trolley 1, a fruit harvesting box 2 connected to one end of the harvesting trolley 1, a negative pressure component 3 for extracting negative pressure installed at the top of the fruit harvesting box 2, a telescopic hose 4 installed on the upper surface of the fruit harvesting box 2, a negative pressure collection cover 5 provided at the other end of the telescopic hose 4, a support frame 6 connected to the other end of the harvesting trolley 1, a lifting component 7 for adjusting the height of the collected berries installed in the inner cavity of the support frame 6, an electric push rod 8 connected to the outer wall of the lifting component 7, the push rod part of the electric push rod 8 passing through the lifting component 7 and provided with a movable seat 9, an installation structure 10 for connecting the negative pressure collection cover 5 installed at the top of the movable seat 9, and a battery box installed on the harvesting trolley 1 to provide basic power for harvesting. The electric push rod 8 is a DTW type with a stroke of 1400mm.

[0025] The negative pressure component 3 is activated to extract negative pressure from the fruit harvesting box 2. The negative pressure in the fruit harvesting box 2 is transmitted to the negative pressure collection hood 5 through the telescopic hose 4. The suction generated in the negative pressure collection hood 5 draws in the coffee cherries, which are then sucked into the fruit harvesting box 2 through the telescopic hose 4 for collection. This achieves rapid harvesting of coffee cherries, avoids the need to find the stem, improves the harvesting efficiency of the harvesting device, and reduces the workload of the staff.

[0026] The surface of the fruit harvesting box 2 has a slot, and a glass plate 11 is installed in the inner cavity of the slot. The glass plate 11 is transparent, and through the glass plate 11, the staff can observe the degree of fruit collection from the outside of the fruit harvesting box 2.

[0027] The negative pressure assembly 3 includes a vacuum negative pressure pump 31, which is bolted to the top of the fruit harvesting box 2. The vacuum port of the vacuum negative pressure pump 31 is connected to a vacuum tube 32. The other end of the vacuum tube 32 extends into the inner cavity of the fruit collection box and is bolted with a filter cover 33. When the vacuum negative pressure pump 31 is started, negative pressure is transmitted to the fruit harvesting box 2 through the vacuum tube 32 to extract negative pressure from the fruit harvesting box 2. The filter cover 33 is used to prevent particles such as leaves from entering the vacuum tube 32 when extracting negative pressure. The model of this vacuum negative pressure pump 31 is Leybold SV65B.

[0028] The lifting assembly 7 includes an electric cylinder 71, which is bolted to the top of the lifting frame. The piston end of the electric cylinder 71 passes through the lifting frame and is fixedly connected to the lifting seat 72. The surface of the lifting seat 72 is bolted to the electric push rod 8. When the electric cylinder 71 is activated, it drives the lifting seat 72 to move, which in turn drives the moving seat 9 to lift and lower, so that the height of the negative pressure collection hood 5 can be adjusted. This allows for the harvesting of coffee cherries at different heights. The electric cylinder 71 is a servo electric cylinder (with rod), model Airtac SET series: SET63-300.

[0029] A support tube is fixedly inserted into the surface of the lifting seat 72, and a slide rod 12 is slidably inserted into the inner cavity of the support tube. Both sides of the slide rod 12 are fixedly connected to the inner side wall of the lifting frame. The support tube and the slide rod 12 work together to support both sides of the lifting seat 72, thereby improving the stability of the vertical movement of the lifting seat 72.

[0030] The mounting structure 10 includes a mounting frame 101, which is bolted to the upper surface of the movable base 9.

The upper surface of the mounting seat 103 is fixedly connected to the bottom end of the negative pressure collection cover 5. Both sides of the mounting seat 103 are fixedly connected with locking blocks 104. The surface of the locking blocks 104 engages with the inner cavity of the slot 102. The mounting seat 103 is inserted into the inner cavity of the mounting frame 101, so that the locking blocks 104 are inserted into the slot 102, thereby assembling the mounting frame 101 and the mounting seat 103, and installing the negative pressure collection cover 5 on the movable base 9.

[0031] The upper surface of the mounting bracket 101 is provided with a threaded hole. The inner cavity of the threaded hole is connected to the inner cavity of the slot 102. A locking bolt 13 is threadedly connected to the inner cavity of the threaded hole. Rotating the locking bolt 13 clockwise causes the locking bolt 13 to move downward and contact the surface of the block 104, thereby positioning the block 104 in the slot 102 and preventing the position of the negative pressure collection cover 5 from shifting after installation.

[0032] A positioning block 14 is fixedly connected to the lower surface of the mounting base 103, and a positioning groove 15 is provided on the upper surface of the movable base 9. The surface of the positioning block 14 and the inner cavity of the positioning groove 15 are engaged and locked together. Through the engagement of the positioning block 14 and the positioning groove 15, the bottom end of the negative pressure collection cover 5 is supported, thereby improving the stability of the movable base 9 when it moves the negative pressure collection cover 5.

[0033] In practical use: the staff pushes the harvesting cart 1 to the side of the coffee berries, starts the electric cylinder 71 to move the lifting seat 72, adjusts the height of the negative pressure collection hood 5, and then starts the vacuum negative pressure pump 31 to draw negative pressure into the berry harvesting box 2 through the vacuum tube 32.
