[0001] This invention relates to the field of mechanical equipment technology, and more specifically, to a coconut juice extraction device and method. Background Technology

[0002] Currently, there are many existing tools for processing coconuts that require opening the shell to extract juice. However, users often find the entire process time-consuming and labor-intensive, with a low success rate, especially in scenarios requiring large-scale and repetitive shell-opening and juice extraction, such as beverage shops and related processing plants. Existing shell-opening and juice extraction tools cannot meet the practical production needs of saving both time and labor. Therefore, there is an urgent need for a simple-to-operate and highly efficient coconut shell-opening and juice extraction device that allows users to easily extract juice by drilling through the coconut shell.

The lower end of the drill rod (51) is provided with a drill bit, which is used to drill the coconut to be juiced fixed on the support platform (2) when the top drilling device (5) is compressed downward.

[0005] Optionally, a receiving hole is provided at one end of the slidable clamping part away from the support shaft and on the same side as the bearing platform, the receiving hole being used to receive the drill rod and / or the drill bit.

[0006] Optionally, a hollow clamping post is accommodated in the receiving hole; a centrally hollow pressing part is fixedly connected to the bottom of the clamping post, and the pressing part protrudes from the lower surface of the receiving hole; the clamping post, the pressing part, and the receiving hole are used to accommodate the drill rod and / or the drill bit.

[0007] Optionally, the bottom of the pressing part has an inwardly concave funnel shape.

[0008] Optionally, there is a gap in the sliding space between the drill rod and the top of the pressing part, or the top of the pressing part has a vent hole for air circulation when the drill rod moves downward.

[0009] Optionally, the slidable clamping part further includes: a first sliding bracket, a second sliding bracket, and a driving device; the first sliding bracket moves up and down along the support shaft under the drive of the driving device, and drives the second sliding bracket to move up and down along the support shaft; the receiving hole is located at the end of the second sliding bracket away from the support shaft.

[0010] Optionally, the drive device includes a handwheel or a motor.

[0011] Optionally, when the driving device is a motor, the coconut juice extraction device further includes: an automatic pole climbing device, and a pressure sensor and / or distance sensing device used in conjunction with the automatic pole climbing device; the automatic pole climbing device is used to start the motor according to the height of the coconut to be juiced, and adjust the height between the support platform and the sliding clamping part.

[0012] Optionally, the top drilling device includes a motor bracket and an automatic drilling device; the bottom of the motor bracket is engaged with a spring reset device; the automatic drilling device is used to control the top drilling device to move vertically, and to stop moving and start rotating the drill rod and drill bit under preset conditions.

[0013] Secondly, embodiments of the present invention also provide a method for extracting juice.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] This invention provides a coconut juice extraction device for extracting juice from coconuts. See also... Figure 1 As shown, the coconut juice extraction device includes, from bottom to top: a bottom support device 1, a support platform 2, a sliding clamping part 3, a spring return device 4, and a top drilling device 5. In this embodiment of the invention, the bottom support device 1 includes a base 11 and a support shaft 12 vertically mounted on the base 11. The base 11 can be placed on the ground or any platform horizontal to the ground. The support shaft 12 can be fixedly connected to the upper surface of the base 11 by welding, bolts, etc. Figure 1As shown, the support shaft 12 can be fixedly connected to one edge of the upper surface of the base 11, so that the upper surface of the base 11 can be used to place the coconut juice storage container. Furthermore, a support platform 2 with a pre-drained liquid outlet hole at the bottom is vertically connected upward along the support shaft 12, that is, the support platform 2 is connected through the support shaft 12. It is used to hold the coconut to be juiced and to allow the coconut juice to flow out. A filter screen can also be set in the support platform 2 to filter the debris generated during drilling. The bottom of the support platform can be set as a circular hole to facilitate the initial placement of the coconut to be juiced.

[0027] Located vertically above the support platform is a sliding clamping part 3, which is also connected to the support shaft 12 through a through hole or other structure, for cooperating with the support platform 2 to fix the coconut to be juiced. It should be noted that the sliding clamping part 3 can have a locking function. The spring return device 4 is located above the sliding clamping part 3. It can be sleeved on the outer surface of the support shaft 12, or it can be set inside the support shaft 12. A limiting ring can be set at the end of the spring return device 4 near the sliding clamping part 3 as a top limit for the sliding clamping part 3 or a bottom limit for the spring return device 4. A top drilling device 5 is set at the end of the spring return device 4 away from the sliding clamping part 3. That is, the top drilling device 5 is connected to the end of the support shaft 12 away from the base 11. The top drilling device 5 can be provided with a round hole to accommodate the support shaft 12, thereby forming a fixed structure with the support shaft 12. By pressing down the top drilling device 5 to compress the spring return device 4, the compressed top drilling device 5 can be reset based on the spring return device 4. Furthermore, the top drilling device 5, at one end away from the support shaft 12, is connected to a drill rod 51 parallel to the support shaft 12, and a drill bit is provided at the lower end of the drill rod 51. Figure 1 (Not directly shown in the text) is used to extend and insert into the coconut to be extracted, which is fixed on the support platform 2, when the top drilling device 5 is compressed downwards, thereby enabling easy opening of the shell and drilling of the juice.

[0028] This invention eliminates the need for the time-consuming and laborious operation of commonly used hammer-type manual coconut openers. The coconut can be directly placed on the support platform 2, and the sliding clamping part 3 can be adjusted so that the end of the sliding clamping part 3 away from the support shaft 12 can be pressed against the coconut, achieving a fixed position. Furthermore, by pressing down the top drilling device 5, the coconut is opened using the drill rod 51 and drill bit to extract juice. After processing one coconut, the top drilling device 5 can be quickly reset by the spring reset device 4. Then, by continuing to adjust the sliding clamping part 3, the coconut to be extracted can be changed, allowing for a quick and simple juice extraction operation. This coconut juice extraction device not only provides convenient positioning and good clamping and fixing effects, but also has a high success rate in opening coconuts and extracting juice. It can drill only one hole at the top of the coconut, or drill two through holes through the top and bottom of the coconut, allowing the coconut juice to flow naturally from the bottom hole into a preset container. It is convenient to use and improves operational efficiency. The overall structure is simple, and the parts are easy to replace; usually, only the drill bit needs to be replaced, meeting the practical production needs of saving both time and labor.

[0029] Optionally, such as Figure 1 As shown, the sliding clamping part 3 has a receiving hole 30 at one end away from the support shaft 12 and on the same side as the support platform 2. The receiving hole 30 can be annular and is used to receive the drill rod 51 and / or drill bit. The receiving hole 30 is aligned with the longitudinal center of the support platform 2 (such as the liquid outlet hole of the support platform 2) and has a guiding and limiting function for the drill rod 51 and / or drill bit, so as to better operate and drill the juice of the coconut to be extracted.

[0030] Optionally, such as Figure 1 As shown, a hollow clamping post 301 is fixedly connected to the receiving hole 30, and the clamping post 301 is accommodated in the receiving hole 30. Figure 1 The diagram shows the clamping post 301 moving downwards under force, and the clamping post 301 can move up and down or be fixed within the receiving hole 30. Furthermore, a centrally hollowed-out pressing part 302 is fixedly connected to the bottom of the clamping post 301, and the pressing part 302 protrudes from the lower surface of the receiving hole 30. A detailed structural diagram of the clamping post 301 and the pressing part 302 can be found in [reference needed]. Figure 2 As shown, the dashed lines represent the internal perspective structure. Because the clamping post 301, the receiving hole 30, and the pressing part 302 are aligned longitudinally, the clamping post 301 can accommodate the through-and-extended drill rod 51 and drill bit when the top drilling device 5 is compressed downwards. This ensures that the drill bit is not exposed whether in use or not, thus protecting the user. It should be noted that the bottom shape of the pressing part 302 can be circular, square, elliptical, tubular, etc. Preferably, the bottom shape of the pressing part 302 is an inwardly concave funnel shape (e.g.,...). Figure 2As shown in the diagram, this design allows the pressing part 302 to be pressed into the outer skin of the coconut, increasing the contact area and sealing performance. This is to cooperate with the clamping post 301 to accommodate the debris generated by the drill bit when drilling the coconut shell, preventing debris from splashing. At the same time, it is also to cooperate with the clamping post 301 to accommodate the coconut juice overflowing from the upper hole caused by the rise of the coconut liquid level due to the drill rod 51 and drill bit extending into the coconut during the process of drilling the upper and lower through holes. When the drill rod 51 and drill bit are reset, the coconut juice contained in the pressing part 302 and the clamping post 301 can return to the coconut, preventing the coconut juice from overflowing from the upper hole of the coconut to the pressing part 302 and the clamping post 301.

[0031] It is understandable that the pressing part 302, together with the clamping column 301, also has the dual functions of accommodating and recovering the overflowing coconut juice and pressing down.

[0032] Optionally, there is a gap in the sliding space between the drill rod 51 and the top of the clamping post 301, or the top of the clamping post 301 has a vent hole to allow air to pass through when it is necessary to drill through the coconut to make two through holes, so that the gas enters the coconut body, balances the pressure, and allows the coconut juice to flow naturally from the lower hole into a preset coconut juice collection container.

[0033] Optionally, such as Figure 3 As shown, the slidable clamping part 3 further includes: a first sliding bracket 31, a second sliding bracket 32, and a driving device 33; the first sliding bracket 31 moves up and down along the support shaft 12 under the drive of the driving device 33, and drives the second sliding bracket 32 ​​to move up and down along the support shaft 12. The first sliding bracket 31 and the second sliding bracket 32 ​​are arranged in a straight line as a single unit, which facilitates observation of their relative position to the coconut during up and down movement, improving alignment. It should be noted that the receiving hole 30 is located at the end of the second sliding bracket 32 ​​furthest from the support shaft 12.

[0034] Optionally, the drive device 33 includes a handwheel or a motor. In other words, the sliding clamping part 3 can be adjusted up and down by manually cranking a handwheel (e.g., ...). Figure 1 As shown), the sliding clamping part 3 is moved by the internal support shaft, worm gear, cylindrical gear, etc.; or, the sliding clamping part 3 can be adjusted to move up and down by electric drive, starting the motor to drive the sliding clamping part 3 to move up and down along the support shaft 12.

[0035] Optionally, when the drive device 33 is a motor, the coconut juice extraction device further includes an automatic pole climbing device. This automatic pole climbing device is used to start the motor according to the height of the coconut to be juiced, and adjust the height between the support platform 2 and the sliding clamping part 3. Therefore, in this case, a pressure sensor and / or distance sensor that works in conjunction with the automatic pole climbing device are also required. In other words, the coconut juice extraction device can install a pressure sensor inside the sliding clamping part 3 (such as the lower end of the clamping column 301). After the motor is turned on to start the automatic pole climbing device, the sliding clamping part 3 is automatically adjusted to move to the top position of the coconut body to be juiced. When the pressure sensor detects that the pressure value has reached a certain value, it is considered that the first position has been reached, and the automatic pole climbing device can stop running, that is, pause the movement of the sliding clamping part 3, and complete the fixation of the coconut to be juiced. Alternatively, a distance sensing device can be installed inside the sliding clamping part 3 (such as the clamping post 301 or the pressing part 302). This device measures the distance between the top of the coconut to be juiced and the sliding clamping part 3. After the automatic pole climbing device is started, the distance sensing device sends a signal with the displacement distance to the controller of the automatic pole climbing device, so that the automatic pole climbing device can control the sliding clamping part 3 to move longitudinally to the position of the top of the coconut to be juiced (for example, a position with a distance difference of 1cm), so that the sliding clamping part 3 (such as the pressing part 302) can fit against the top of the coconut to be juiced. Preferably, an additional stroke of 0.2-1cm is added to the 1cm difference to allow the sliding clamping part 3 to be embedded more deeply into the coconut skin to be juiced, preventing the juice from leaking out or overflowing when drilling. Alternatively, a distance sensing device can be installed inside the sliding clamping part 3 (such as the clamping column 301 or the pressing part 302), and a pressure sensor can be installed inside the sliding clamping part 3 (such as the lower end of the clamping column 301). This allows the distance sensing device to measure the distance and the automatic climbing device to move to the approximate position. After sensing the pressure signal transmitted by the pressure sensor, the device can accurately determine that the top of the coconut to be juiced has been clamped. This not only enables automatic adjustment of the sliding clamping part 3, but also further improves the accuracy of movement.

[0036] In addition, embodiments of the present invention may also include a pressure sensor built into the drill bit. After drilling through two juice extraction holes, the automatic pole climbing device automatically identifies the relevant data signals of the pressure sensor, such as determining the reset signal, and finally completes the reset of the sliding clamping part 3.

[0037] Optionally, the top drilling device 5 includes a motor bracket 52 and an automatic drilling device. The motor bracket 52, as its name suggests, is used to house the motor, further improving the manual operation of pressing down the top drilling device 5 from manual to fully automatic operation, thus increasing productivity. The bottom of the motor bracket 52 engages with the spring return device 4, serving as a limiting device for the top of the spring return device 4. In this embodiment, a shim can be provided at the engagement point between the bottom of the motor bracket 52 and the spring return device 4 to buffer the return impact.

[0038] Furthermore, the automatic drilling device controls the vertical movement of the top drilling device 5 and initiates the rotation of the drill bit under preset conditions. It can be understood that embodiments of the invention can also activate the automatic drilling device based on an activated motor, automatically adjusting the downward movement of the top drilling device 5, stopping the downward movement under preset conditions, and initiating the rotation of the drill bit. It should be noted that the preset conditions can be either when the pressure sensor of the drill bit detects that the pressure value reaches a certain value, or when the distance sensor detects that the top drilling device 5 has moved to a preset position. When the preset condition is that the distance sensor detects that the top drilling device 5 has moved to a preset position, the set downward pressure distance can be increased by 1-5 cm to ensure that the drill bit can penetrate the entire coconut body from which the juice is to be extracted.

[0039] In addition, embodiments of the present invention can also be based on the pressure sensor built into the drill bit. After drilling through two juice extraction holes, the automatic drilling device can automatically identify the relevant data signals of the pressure sensor, such as determining the reset signal, and finally complete the reset of the top drilling device 5.

[0040] This invention also provides a method for extracting juice, such as... Figure 4 As shown, when it is necessary to use a coconut juice extraction device to break open the coconut and extract juice, the following steps 101-102 are included.

[0041] Step 101: By controlling the sliding clamping part of the coconut juice extraction device to move vertically along the support shaft, the coconut to be juiced is clamped and fixed on the carrier platform of the coconut juice extraction device.

[0042] Place the coconut to be juiced on the support platform of the coconut juice extraction device. Adjust the sliding clamping part of the coconut juice extraction device to move vertically on the support shaft, so that the end of the sliding clamping part near the coconut to be juiced is pressed down to the top of the coconut to be juiced for clamping and fixing, so that the bottom of the sliding clamping part is embedded in the inside of the coconut skin / shell to better fit the outer skin.

[0043] Step 102: The top drilling device of the coconut juice extraction device is compressed downward, which drives the drill rod below the top drilling device to move downward to the shell of the coconut to be extracted, drill in and open the shell.

[0044] The coconut juice extraction device can be manually operated by pressing down the top drilling device, which moves the drill rod below it downwards to the shell of the coconut from which juice is extracted, thus drilling into and opening the shell to extract the juice. Alternatively, the top drilling device can be electrically controlled to compress downwards.

[0045] Optionally, step 101 above, "by controlling the slidable clamping part of the coconut juice extraction device to move vertically along the support shaft, clamping and fixing the coconut to be juiced at the carrier platform of the coconut juice extraction device", may include the following steps A1-A2.

[0046] Step A1: By controlling the first sliding bracket in the sliding clamp to move vertically along the support shaft, the second sliding bracket is driven to move vertically along the support shaft.

[0047] For example, the first sliding bracket can be moved up and down on the support shaft by cranking a handwheel connected to it, thereby moving the second sliding bracket; alternatively, the first sliding bracket can be connected to a motor and an automatic pole-climbing device to achieve automated adjustment. In other words, the methods for controlling the sliding clamping part of the coconut juice extraction device to move vertically on the support shaft include manual control or electric control.

[0048] Step A2: Insert the pressing part located on the side of the second sliding bracket away from the support axis and on the same side as the support platform into the interior of the coconut from which the juice is to be extracted.

[0049] Optionally, step A2 above, "drilling in and opening the shell," may include: drilling open the shell based on the rotation of the drill bit at the lower end of the drill rod; in other words, a detachable and rotatable drill bit may be used to further drill into the shell of the coconut from which the juice is to be extracted, i.e., to open the top juicing hole, allowing air to enter the coconut from the leaking gap. The control method for the rotation of the drill bit may also include: manual control or electric control.

[0050] Optionally, after drilling into and opening the shell, the juice extraction method further includes: using a spring-reset device of the coconut juice extraction device to reset the top drilling device; or, when the user wishes to use a container to hold the juice, placing a container on the base of the coconut juice extraction device, continuing to compress the top drilling device downwards until the bottom of the coconut to be juiced is penetrated, allowing the juice to flow into the container, and then using the spring-reset device of the coconut juice extraction device to reset the top drilling device. For example, when the user releases the pressed-down top drilling device, the spring-reset device drives the top drilling device (including the drill rod and drill bit) to rise and reset. It should be noted that the fully automated adjustment of the sliding clamping part and the top drilling device has been described in the aforementioned description of the relevant structures and will not be repeated here.

[0051] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
