Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable deep processing technology, specifically to a fruit juicer with a self-cleaning and self-feeding structure. Background Technology

[0002] Fruit juicing equipment is a common piece of equipment in the field of deep processing of fruits and vegetables. It is mainly used to crush and press various fresh fruits to obtain fruit juice beverages. It is widely used in food processing, beverage production and household fruit and vegetable processing. At present, traditional fruit juicers on the market still have many technical defects in actual use, making it difficult to meet the needs of large-scale, automated and high-quality juicing production.

[0003] However, existing fruit juicers still have some problems when in use: An existing automatic fruit juicing device, such as the one described in Chinese patent application number CN202011543324.1, can change the intensity of fruit washing by altering the height of the water pipes in the washing device; it can also control the crushing effect and juicing rate by changing the angle of the juicing fan blades in the juicing device. The device comprises a juicing device, a pressing device, a washing device, and a belt. Rotating knob one causes a rotating rod to rotate, which in turn rotates two upper gears, which in turn rotates gear three, causing small cylinder one to rotate, thus changing the angle of the stirring blades and altering the crushing effect. Rotating knob two causes two functional gears to rotate, which in turn causes two straight gears one to rise or fall, thereby raising or lowering the water pipe support, thus changing the height of the four water pipes and thus altering the intensity of fruit washing. Different washing heights can be set for fruits with different peel strengths.

[0004] While existing fruit juicing devices have cleaning mechanisms, they lack drying structures. This results in water stains remaining after fruit washing, which can affect the purity and cleanliness of the juice extracted later.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing fruit juicer with a self-cleaning and self-feeding structure. Summary of the Invention

[0006] The purpose of this invention is to provide a fruit juicer with a self-cleaning feeding structure, in order to solve the problem mentioned in the background art that existing fruit juicers leave certain water stains after cleaning, which affects the purity and cleanliness of subsequent fruit juice extraction.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fruit juicer with a self-cleaning and self-feeding structure, comprising a support frame and a feeding box mounted on its upper end, and a juicing shell mounted on the lower end of the feeding box. The feeding box is equipped with a crushing shaft, the bottom of the feeding box is equipped with an auger shaft, the juicing shell is equipped with a juicing shaft, the bottom of the juicing shell is opened with a liquid outlet, the liquid outlet is equipped with a filter screen, the end of the juicing shell is opened with a discharge port, and a transmission component is connected between the juicing shaft and the auger shaft. A cleaning box is fixed to the side of the bracket. A feeding conveyor belt is installed at an angle on the left side of the cleaning box. The upper end of the feeding conveyor belt extends into the inside of the feeding box. A transmission rod is rotatably installed inside the cleaning box. A lever is fixed to the outer wall of the transmission rod. A second motor is fixed to the top of the cleaning box. The shaft end of the second motor is connected to the transmission rod. A first diversion pipe is installed above the feeding conveyor belt, and a nozzle is connected to the lower end of the first diversion pipe. A second diversion pipe is installed on the side of the first diversion pipe, and an air jet cover is fixed to the lower end of the second diversion pipe. A piston assembly is installed inside the cleaning box, and the piston assembly can supply liquid and air to the nozzle and the air jet cover simultaneously.

[0008] Preferably, the crushing motor shaft is connected to the crushing shaft, the bottom of the feeding box is connected to a horizontally arranged feeding pipe, the end of the feeding pipe is connected to the juicing shell, and the auger shaft is installed inside the feeding pipe and is adapted to the feeding pipe.

[0009] By adopting the above technical solution, the crushing shaft is driven by an independent crushing motor, which can fully crush and pre-treat the input fruit, refine the particle size of the fruit material, and at the same time, the horizontally arranged feeding pipe, with a suitable auger shaft, can stably and quantitatively transport the crushed fruit material to the juicing shell, effectively avoiding material accumulation and blockage of the feeding channel, ensuring continuous feeding, laying a good foundation for subsequent efficient juicing, and improving the overall stability of the machine operation.

[0010] Preferably, the transmission assembly includes a first motor fixed to the side of the bracket, the front end of the first motor being connected to the juicing shaft, and a first pulley being installed at the rear end of the first motor and the rear end of the auger shaft, with a first transmission belt connecting the two sets of first pulleys.

[0011] Using the above technical solution, the transmission component adopts a linkage structure of pulley and transmission belt. A single first motor can synchronously drive the juicing shaft and auger shaft to operate synchronously, eliminating the need for multiple drive devices. This greatly simplifies the equipment transmission structure, reduces the overall production cost and energy consumption, and ensures a high degree of matching between the feeding and juicing processes, avoiding process disconnection and effectively improving the overall coordination and efficiency of the juicing operation.

[0012] Preferably, the levers are arranged in a ring array on the outer wall of the transmission rod, and the transmission rods are symmetrically arranged on both sides and staggered on both sides of the cleaning tank.

[0013] Using the above technical solution, the circular array of multiple levers can turn and lift the fruit in the washing box from all directions, allowing the fruit to fully contact the washing liquid and improve the uniformity of washing. The staggered and symmetrical distribution of the two sets of transmission rods can prevent fruit from sticking or piling up, eliminate washing dead corners, completely solve the problem of incomplete local washing, and significantly improve the overall cleanliness of the fruit.

[0014] Preferably, the upper ends of both sets of transmission rods are connected to second pulleys, and a second transmission belt is connected between the two sets of second pulleys.

[0015] Using the above technical solution, the two sets of transmission rods are linked and driven by the second pulley and the second transmission belt. A single second motor can drive the two sets of transmission rods to rotate in opposite directions, driving the double-sided levers to work together. This linkage structure has strong transmission stability, which can ensure that the fruit turning rhythm on both sides is uniform, avoid imbalance in unilateral operation, and at the same time simplify the drive structure, reduce equipment failure rate and later maintenance costs.

[0016] Preferably, the lower end of the first diverter tube is designed in an "I" shape, and nozzles are connected to both sides of the first diverter tube. The nozzles are designed to be inclined, and the two nozzles are designed to be inclined in opposite directions.

[0017] Using the above technical solution, the first diversion pipe with the I-shaped structure can realize water flow diversion and pressure stabilization, ensuring uniform and stable liquid output on both sides. The spray nozzles tilted in opposite directions on both sides can form a bidirectional cross spray water flow, which can fully cover the fruit conveyed by the feeding conveyor belt, and wash the fruit in all directions during the feeding process without any blind spots, further enhancing the fruit cleaning effect, connecting with the cleaning process inside the box, and improving the overall cleaning quality.

[0018] Preferably, the lower end of the jet hood has a strip-shaped jet nozzle, and two sets of jet nozzles are provided. The two sets of jet nozzles are designed in parallel, and the second transmission belt is arranged in a figure-eight shape.

[0019] Using the above technical solution, the two sets of parallel strip-shaped air jets at the bottom of the jet hood can output uniform and wide-range airflow, which can blow and drain water from the fruit after washing and spraying. The strip-shaped air jets have a wide air coverage and uniform air force, which can quickly blow away residual water stains and impurities on the surface of the fruit, replacing natural drainage, greatly shortening the drainage time, effectively improving the efficiency of pre-treatment, and ensuring that the juiced material is dry and clean.

[0020] Preferably, the piston assembly includes a sealing tube fixed to the inner wall of the cleaning tank, a piston body slidably installed inside the sealing tube, and a transmission connecting rod slidably installed on the side end of the sealing tube. The transmission connecting rod is fixed to the piston body.

[0021] Using the above technical solution, the piston assembly drives the piston body to slide smoothly back and forth in the sealed tube through the transmission connecting rod. It has a compact structure and high operational stability. Relying on the reciprocating motion of the piston, it can stably realize the liquid suction, air suction and liquid pressure, and air pressure operations of the cavity, providing a continuous and stable power source for the spray and air jet structure. There is no need to configure additional air supply and liquid supply pumps, which simplifies the equipment structure and reduces the equipment size and energy consumption.

[0022] Preferably, a drive motor is connected to the outer wall of the cleaning tank, a reciprocating lead screw is connected to the end of the drive motor, a drive plate is fixed to the end of the drive connecting rod, and the reciprocating lead screw is connected to the drive plate.

[0023] Using the above technical solution, the reciprocating screw is driven by a transmission motor to rotate, which in turn drives the transmission plate and the linked piston assembly to make precise reciprocating linear motion. The screw drive method has high transmission accuracy and stable operation. It can accurately control the piston stroke and frequency, and stably adjust the pressure and flow of liquid and air supply, so that the washing spray and blowing dewatering operations can maintain a uniform and stable speed. It is suitable for the pre-treatment needs of different fruits, and the equipment has stronger adaptability.

[0024] Preferably, a liquid supply chamber and an air supply chamber are respectively provided at both ends of the sealing tube. The two sets of sealing tubes are symmetrically distributed and the cavities are arranged in opposite directions. A first conduit is connected between the two sets of liquid supply chambers. A first diverter is connected to the first conduit. An inlet pipe is connected to the side of the cleaning tank and is connected to the liquid supply chamber. A second conduit is connected between the two sets of air supply chambers and is connected to the second diverter. A filter is connected to the side of the air supply chamber. The inlet pipe, the first conduit, the second conduit, the filter, and the liquid supply chamber and air supply chamber are all connected by one-way valves.

[0025] Using the above technical solution, the symmetrical and reverse-sealable cavities can independently complete liquid and gas supply operations, with clear division of labor and no interference between them. With the one-way valves of each pipeline, liquid and gas backflow can be prevented, ensuring the stability of gas and liquid transportation. The filter can purify the gas supply airflow and prevent impurities from contaminating the fruit. This structure can simultaneously power the spray and air jet structures, making it a dual-purpose machine that greatly improves the integration of the equipment and the efficiency of operation. In addition, the two sets of sealing pipes can achieve continuous and uninterrupted liquid and gas supply.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: This fruit juicer with a self-cleaning and self-feeding structure integrates automatic cleaning and automatic feeding into one integrated structure. The fruit is turned and stirred by the staggered and symmetrical lever structure inside the cleaning tank, and the bidirectional cross-tilted nozzles above the feeding conveyor belt form an all-round spray cleaning, which can thoroughly remove dust and impurities from the surface of the fruit, eliminating the dead corner problem of traditional cleaning methods. At the same time, the air blowing structure with parallel strip jet nozzles can quickly dry the residual water stains on the surface of the fruit, replacing the inefficient natural drainage method, effectively improving the cleanliness and efficiency of the pre-processing of fruit, avoiding water stains and impurities from affecting the quality of subsequent juice, and realizing the overall automated pre-processing operation, reducing the intensity of manual labor.

[0027] 1. Adopting a highly integrated linkage transmission structure, a single first motor can synchronously drive the auger shaft and the juicing shaft, achieving precise synchronization of the feeding and juicing processes. At the same time, the figure-eight second transmission belt enables the double-sided transmission rods to rotate in opposite directions, ensuring that the fruit is turned and cleaned evenly and stably. Compared with the traditional multi-motor independent drive structure, this structure greatly simplifies the equipment parts, reduces the equipment manufacturing cost and operating energy consumption, effectively avoids problems such as material blockage and process disconnection, significantly improves the overall machine's operating stability and operational coordination, and reduces the probability of equipment failure and subsequent maintenance costs. 2. A symmetrical, reverse-sealable double-sealed piston liquid and gas supply structure is set up, and the two chambers can work alternately to achieve uninterrupted and continuous liquid and gas supply. This effectively solves the drawbacks of the traditional single-chamber power supply and discontinuous operation. At the same time, the one-way valves in each pipeline can effectively prevent gas and liquid backflow and ensure stable delivery pressure. With the filter, the airflow can be purified to avoid secondary contamination of fruit materials. This structure can simultaneously provide stable power for spray cleaning and air drying and dewatering structures. It is a dual-purpose machine with high integration, which greatly improves the continuous operation capability of the equipment and is suitable for a variety of fruit processing scenarios. The equipment has greater versatility and practicality. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-10This invention provides a technical solution: a fruit juicer with a self-cleaning feeding structure, comprising a support frame 1 and a feeding box 2 installed at its upper end, a juicing shell 6 installed at the lower end of the feeding box 2, a crushing shaft 3 installed inside the feeding box 2, an auger shaft 5 installed at the bottom of the feeding box 2, a juicing shaft 7 installed inside the juicing shell 6, a leakage port opened at the bottom of the juicing shell 6, a filter screen installed inside the leakage port, a discharge port opened at the end of the juicing shell 6, and a transmission assembly connecting the juicing shaft 7 and the auger shaft 5; a crushing motor 4 is connected to the crushing shaft 3 at its shaft end, a horizontally arranged feeding pipe is connected to the bottom of the feeding box 2, the end of the feeding pipe is connected to the juicing shell 6, the auger shaft 5 is installed inside the feeding pipe, and the auger shaft 5 is adapted to the feeding pipe; the transmission assembly includes a first motor 8 fixed to the side end of the support frame 1, the front end of the first motor 8 is connected to the juicing shaft 7, and a first pulley 9 is installed at the rear end of the first motor 8 and the rear end of the auger shaft 5, and a first transmission belt 10 is connected between the two sets of first pulleys 9. In actual use, the fruit to be juiced is put into the feeding box 2, and the crushing motor 4 is started simultaneously to drive the crushing shaft 3 to rotate at high speed. After the crushing shaft 3 rotates, it can cut the put-in fruit into small pieces, and the chopped fruit falls into the bottom of the feeding box 2. The first motor 8 is started simultaneously. The first motor 8 cooperates with the first pulley 9 and the first transmission belt 10 to drive the auger shaft 5 and the juicing shaft 7 to rotate synchronously. The auger shaft 5 transports the chopped fruit pieces into the juicing shell 6. Juicing is achieved during the continuous rotation of the juicing shaft 7. The juice is filtered through the filter screen in the leakage port at the bottom of the juicing shell 6 and discharged, while the fruit residue is discharged from the discharge port at the end of the juicing shell 6.

[0032] A cleaning box 11 is fixed to the side of the bracket 1. A feeding conveyor belt 12 is installed at an angle on the left side of the cleaning box 11. The upper end of the feeding conveyor belt 12 extends into the inside of the feeding box 2. A transmission rod 13 is rotatably installed inside the cleaning box 11. A lever 14 is fixed to the outer wall of the transmission rod 13. A second motor 17 is fixed to the top of the cleaning box 11. The shaft end of the second motor 17 is connected to the transmission rod 13. The levers 14 are arranged in a ring array on the outer wall of the transmission rod 13. The transmission rods 13 are symmetrically arranged on both sides and staggered on both sides of the cleaning box 11. The upper ends of the two sets of transmission rods 13 are connected to the second pulleys 15. A second transmission belt 16 is connected between the two sets of second pulleys 15. The second transmission belt 16 is arranged in a figure-eight shape. Before juicing the fruit, it needs to be washed. The fruit is poured into the washing tank 11, and clean water is added. The second motor 17 is started. The second motor 17, in conjunction with the second transmission belt 16 and the second pulley 15, controls the synchronous rotation of the two sets of transmission rods 13 and levers 14. The second transmission belt 16 is arranged in an "8" shape, thus achieving opposite rotation of the two sets of transmission rods 13. During rotation, the fruit is continuously agitated for washing, and simultaneously moved towards the feeding conveyor belt 12. The feeding conveyor belt 12 then transports the washed fruit into the feeding box 2. The clean water inside the washing tank 11 is used to wash away surface dirt, and a subsequent rinsing structure further cleans the fruit.

[0033] A first diversion pipe 18 is installed above the feeding conveyor belt 12, with a nozzle 19 connected to its lower end. A second diversion pipe 20 is installed on the side of the first diversion pipe 18, with an air jet cover 31 fixed to its lower end. A piston assembly is installed inside the washing tank 11, which can simultaneously supply liquid and air to the nozzle 19 and the air jet cover 31. The lower end of the first diversion pipe 18 is designed in an "I" shape, with nozzles 19 connected to both sides of the first diversion pipe 18. The nozzles 19 are designed with an inclined design, and the two nozzles on both sides are designed with opposite inclination directions. A strip-shaped air jet is opened at the lower end of the air jet cover 31, with two sets of air jets arranged in parallel. The surface of the feeding conveyor belt 12 is arrayed with drainage holes, and baffles are installed in an equidistant array on the outside, which not only improves the drainage efficiency, but also keeps the fruit stable and conveyed upwards. Above the feeding conveyor belt 12 is an integrated spraying and drying structure, which can complete secondary spraying and drying during fruit transportation, further improving the cleanliness of the fruit. As the initially cleaned fruit is conveyed upwards by the feeding conveyor belt 12, clean water is supplied to two sets of nozzles 19 via the first diversion pipe 18. The two sets of relatively inclined nozzles 19 perform a secondary rinse from both sides during the upward transport of the fruit, removing residual stains, foam, and other impurities from the fruit surface. After the secondary rinse, since water stains remain on the fruit surface, a jet structure is installed. High-speed airflow is used to blow away the remaining water stains. High-pressure gas is supplied to the jet hood 31 via the second diversion pipe 20 and ejected from the strip-shaped jet nozzle below to dry the fruit surface, ensuring the quality of subsequent fruit juicing.

[0034] The piston assembly includes a sealing tube 21 fixed to the inner wall of the cleaning tank 11, a piston body 22 slidably mounted inside the sealing tube 21, and a transmission connecting rod 23 slidably mounted on the side end of the sealing tube 21. The transmission connecting rod 23 is fixed to the piston body 22. A transmission motor 25 is connected to the outer wall of the cleaning tank 11. A reciprocating lead screw 26 is connected to the end of the transmission motor 25. A transmission plate 24 is fixed to the end of the transmission connecting rod 23, and the reciprocating lead screw 26 is connected to the transmission plate 24. A liquid supply chamber and a gas supply chamber are respectively provided at both ends of the sealing tube 21. Two sets of sealing tubes 21 are provided. The chambers are symmetrically distributed and arranged in opposite directions. The first conduit 28 connects the two sets of liquid supply chambers. The first diverter pipe 18 is connected to the first conduit 28. The inlet pipe 27 is connected to the side of the cleaning tank 11 and is connected to the liquid supply chamber. The second conduit 29 connects the two sets of air supply chambers and is connected to the second diverter pipe 20. A filter 30 is connected to the side of the air supply chamber. The inlet pipe 27, the first conduit 28, the second conduit 29, the filter 30, and the liquid supply chamber and air supply chamber are all connected by one-way valves. The cleaning tank 11 is equipped with a piston assembly, which serves as an integrated power structure for the spraying liquid supply and air drying air supply of the entire machine. It can simultaneously and stably supply liquid and air to the nozzles 19 and the air hood 31 without the need for an additional independent pump body. The structure has a high degree of integration. When the equipment is working, the drive motor 25 is started first. The drive motor 25 drives the reciprocating screw 26 to rotate continuously. Utilizing the screw transmission characteristics of the reciprocating screw 26, the transmission plate 24 is driven to make a stable linear reciprocating motion. Then, through the transmission connecting rod 23, the piston body 22 is pulled to perform high-precision reciprocating sliding inside the sealing tube 21. Through the reciprocating movement of the piston body 22, the internal volume of the liquid supply chamber and the air supply chamber at both ends of the sealing tube 21 can be changed periodically, generating negative pressure adsorption and positive pressure squeezing effects, respectively, providing continuous power for the equipment's spraying and air drying operations. During the retraction and sliding of the piston body 22, a negative pressure is formed inside the liquid supply chamber and the air supply chamber. Under the conduction and limiting action of the one-way valve, the external cleaning liquid is drawn into the liquid supply chamber through the liquid inlet pipe 27 on the side of the cleaning tank 11. At the same time, the outside air is filtered and purified by the filter 30 and then drawn into the air supply chamber, effectively preventing dust and impurities in the air from entering the pipeline and avoiding secondary pollution to the fruit. This process completes the automatic liquid and air storage operation. During the forward sliding of the piston body 22, the liquid supply chamber and the air supply chamber are pressurized to form a positive pressure. At this time, the one-way valves at the liquid inlet pipe 27 and the filter 30 are automatically closed, and the one-way valves at the first conduit 28 and the second conduit 29 are opened. The cleaning liquid in the liquid supply chamber is transported to the first diversion pipe 18 through the first conduit 28, and cross water flow is formed through the two opposite tilting nozzles 19 on both sides to spray and clean the fruit on the conveyor belt in all directions. At the same time, the high-pressure gas in the air supply chamber is transported to the second diversion pipe 20 through the second conduit 29, and is sprayed out from the two sets of parallel strip-shaped air nozzles at the bottom of the air jet cover 31 to evenly blow and drain the cleaned fruit.The two sets of sealing tubes 21 are arranged in a symmetrical and opposite cavity structure. During operation, they can form an alternating energy absorption and energy supply state, complementing each other and working together to effectively solve the problem of intermittent energy supply in traditional single cavity, and achieve uninterrupted continuous liquid and gas supply.
