Technical Field

[0001] This utility model belongs to the field of tomato processing technology, specifically a spraying device for washing tomatoes. Background Technology

[0002] The fruit of the tomato is a juicy berry composed of pulp and a sap. The former includes the pericarp and epidermis, while the latter includes the placenta and cavities containing the seeds. During tomato processing, washing equipment is required to clean the tomatoes.

[0003] The existing utility model with authorization announcement number CN217771374U discloses an adjustable pressure tomato spraying and cleaning device, including a base, a cleaning box fixedly installed on the left side of the top of the base via a support leg, a placement mesh plate fixedly installed in the inner cavity of the cleaning box, and a filter box fixedly installed on the right side of the top of the base.

[0004] The above technical solution solves the problem that traditional tomato washing equipment is not easy to adjust water pressure. However, due to the irregular shape of tomatoes, the device is prone to forming spray dead zones when spraying the surface of tomatoes, resulting in incomplete cleaning and reducing the practicality of the device.

[0005] Therefore, we propose a spray device for washing tomatoes to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a spraying device for washing tomatoes, so as to solve the technical problem that dead spots are easily generated during the washing of tomatoes in the prior art.

[0007] To solve the above technical problems, the technical solution of this utility model is as follows: a spraying device for washing tomatoes, including a casing, with a rack for holding tomatoes slidably connected inside the casing. The casing is equipped with a spraying system and an airflow tumbling system. The airflow tumbling system includes an air pump, two solenoid valves, two conveying pipes, and two jet nozzles. The air pump is fixedly connected to the outside of the casing. The air outlet of the air pump is connected to a three-way pipe. The two ends of the three-way pipe are respectively connected to the air inlets of the two conveying pipes through the solenoid valves. The air outlets of the two conveying pipes are respectively connected to the two jet nozzles. The jet nozzles are symmetrically arranged on both sides of the casing. Each jet nozzle is driven by a rotary motor to reciprocate. The two rotary motors are fixedly connected to both sides of the casing. The output end of each rotary motor extends through into the casing and is fixedly mounted on a turntable. A connecting column is slidably connected to the eccentric position of the turntable. A connecting frame is slidably connected to the outer end of the connecting column. A mounting plate is fixedly connected to the other end of the connecting frame. The jet nozzles are fixedly connected to the mounting plate. A fixing plate is fixedly connected to the inner wall of the casing. The fixing plate is located on the upper and lower sides of the connecting frame and is rotatably connected to the connecting frame.

[0008] Furthermore, the spraying system includes a water storage tank, a metering pump, a spray pipe, and several nozzles. The input end of the metering pump is connected to the water storage tank, and the output end is connected to the spray pipe. The nozzles are fixedly connected to the spray pipe and face the placement frame.

[0009] Furthermore, a water inlet pipe is fixedly connected to the upper surface of the water storage tank, and a tank cover is threadedly connected to the outer surface of the water inlet pipe.

[0010] Furthermore, two sets of casters are fixedly installed on the bottom surface of the chassis, and a brake pad is fixedly installed on the outer surface of each caster.

[0011] Furthermore, a water outlet pipe is fixedly connected to the front of the chassis, and a valve is fixedly connected to the outer surface of the water outlet pipe.

[0012] Furthermore, a locking block and a locking frame are fixedly installed on the front of the chassis, with the locking block snapping into the inside of the locking frame.

[0013] Furthermore, a support platform is fixedly installed on the bottom surface of each of the rotating motors, and the sides of the two support platforms that are close to each other are fixedly connected to the two sides of the chassis respectively.

[0014] Furthermore, a controller is fixedly installed on the left side of the chassis, and both solenoid valves are controlled by the controller. A protective box is provided on the outside of the controller, and a protective cover is hinged to the side of the protective box.

[0015] This utility model has the following advantages compared with the prior art:

[0016] 1. This utility model, by setting up an airflow turning system consisting of an air pump, a solenoid valve, and two swingable jet nozzles, can use intermittent, alternating jets of airflow to impact the tomatoes on the rack, causing them to roll and turn over within the rack. This effectively avoids spray dead zones caused by the irregular shape of the tomatoes and their overlapping, thus achieving more uniform cleaning of the tomato surface and improving the cleaning effect and cleanliness. By using a swinging mechanism consisting of a rotating motor, a turntable, and a connecting frame to drive the jet nozzles to swing back and forth, the airflow can cover different areas of the rack, further enhancing the thoroughness of the turning and improving the cleaning effectiveness of the device.

[0017] 2. This invention uses a controller to alternately open and close two solenoid valves, causing the air nozzles on both sides to spray intermittently. This not only simulates the effect of manual turning but also effectively saves energy from the air pump. It also avoids the problem of tomatoes being blown off the rack or piling up in a corner due to continuous unilateral blowing, ensuring a stable and controllable turning process. The combination of spray cleaning and airflow turning, with a reasonable process design of spraying first, then turning, then spraying again, ensures cleaning effectiveness while avoiding water interference with the turning process. The entire device is highly automated, easy to operate, reduces the labor intensity of operators, and improves the production efficiency of tomato cleaning. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 The tomato washing spray device shown includes a housing 1. A rack 3 for holding tomatoes is slidably connected inside the housing 1. The housing 1 is equipped with a spraying system and an airflow agitation system. The airflow agitation system includes an air pump 4, two solenoid valves 6, two delivery pipes 7, and two air nozzles 14. The air pump 4 is fixedly connected to the outside of the housing 1. The air outlet of the air pump 4 is connected to a three-way pipe 5. Both ends of the three-way pipe 5 are connected to the air inlets of the two delivery pipes 7 via the solenoid valves 6. The air outlets of the two delivery pipes 7 are connected to the two air nozzles 14. The two air nozzles 14 are symmetrically arranged inside the housing 1. On both sides, two jet nozzles 14 are driven by two rotating motors 8 to reciprocate. The two rotating motors 8 are fixedly connected to the two sides of the housing 1. The output end of the rotating motor 8 extends through into the housing 1 and is fixedly installed with a turntable 9. A connecting column 10 is slidably connected at the eccentric position of the turntable 9. A connecting frame 12 is slidably connected to the outer end of the connecting column 10. A mounting plate 13 is fixedly connected to the other end of the connecting frame 12. The jet nozzle 14 is fixedly connected to the mounting plate 13. A fixing plate 11 is fixedly connected to the inner wall of the housing 1. The fixing plate 11 is set on the upper and lower sides of the connecting frame 12 and is rotatably connected to the connecting frame 12.

[0025] To clean the tomatoes inside the casing 1, a spraying system includes a water tank 15, a metering pump 16, spray pipes 17, and several nozzles 18. The water tank 15 and metering pump 16 are fixedly connected to the top of the casing 1. The spray pipes 17 are installed on the top of the casing 1. The input end of the metering pump 16 is connected to the water tank 15, and the output end of the metering pump 16 is connected to the spray pipes 17. Five spray pipes 17 are arranged parallel to each other inside the casing 1, and each spray pipe 17 is connected to the others via a pipe. Multiple nozzles 18 are fixedly connected to the spray pipes 17 and face the rack 3. Powered by the metering pump 16, water from the water tank 15 is sprayed through the spray pipes 17 and nozzles 18 onto the inside of the rack 3, thus spraying the tomatoes inside the rack 3.

[0026] A water inlet pipe 25 is fixedly connected to the upper surface of the water storage tank 15, and a tank cover 26 is threadedly connected to the outer surface of the water inlet pipe 25. The installation of the water inlet pipe 25 and the tank cover 26 facilitates workers to fill the water storage tank 15 with water.

[0027] Two sets of casters 19 are fixedly installed on the bottom surface of the casing 1, and a brake pad 20 is fixedly installed on the outer surface of each caster 19. The installation of the casters 19 makes it convenient for workers to move the device, thereby increasing the ease of movement of the device. The installation of the brake pad 20 plays a role in locking the casters 19, thereby preventing the casters 19 from rotating on their own.

[0028] A water outlet pipe 21 is fixedly connected to the front of the casing 1, and a valve 22 is fixedly connected to the outer surface of the water outlet pipe 21. The installation of the water outlet pipe 21 and the valve 22 serves to discharge the water inside the casing 1, thereby facilitating the centralized discharge of cleaning water inside the casing 1 by workers.

[0029] Locking blocks 23 and locking frames 24 are fixedly installed on the front of the chassis 1, with the locking blocks 23 engaging inside the locking frames 24. The installation of the locking blocks 23 and locking frames 24 serves to lock the chassis 1, thereby preventing the chassis 1 from opening on its own.

[0030] Each rotating motor 8 has a support platform 27 fixedly mounted on its bottom surface. The sides of the two support platforms 27 that are close to each other are fixedly connected to the two sides of the housing 1. The installation of the support platforms 27 serves to fix the rotating motor 8, thereby preventing the rotating motor 8 from rotating on its own during operation and ensuring the stability of the rotating motor 8 during operation.

[0031] A controller 2 is fixedly installed on the left side of the casing 1. Both solenoid valves 6 are controlled by the controller 2. The controller 2 can control the opening and closing of the two solenoid valves 6 separately. When the operator starts the air pump 4, the controller 2 is also started simultaneously. At this time, the controller 2 controls one solenoid valve 6 to open for ten seconds, while the other solenoid valve 6 closes. After ten seconds, the opening and closing states of the two solenoid valves 6 are changed, alternately controlling the two solenoid valves 6 to open and close. A protective box 28 is installed on the outside of the controller 2, and a protective cover 29 is hinged to the side of the protective box 28. The protective box 28 and the protective cover 29 serve to provide safety protection for the controller 2.

[0032] The specific working process of this utility model is as follows:

[0033] Workers place the tomatoes to be washed inside the rack 3, then attach the rack 3 to the inside of the machine housing 1, close the housing 1, and attach the locking bracket 24 to the locking block 23. Next, the worker turns on the metering pump 16 and adjusts the water flow rate to regulate the water pressure. The water from the water tank 15 is sprayed through the spray pipe 17 and nozzles 18 onto the inside of the rack 3, thus rinsing the tomatoes. After spraying for a period of time, the tomatoes are turned over, at which point the worker temporarily turns off the metering pump 16. Turn on the air pump 4, and alternately open the two solenoid valves 6 via the controller 2. The air pump 4 powers external air through the three-way pipe 5, delivery pipe 7, and nozzle 14, blowing it onto the tomatoes inside the rack 3, thus agitating them. Simultaneously, the rotating motor 8 powers the turntable 9, which in turn rotates the connecting column 10. This causes the connecting column 10 to swing the connecting frame 12 and mounting plate 13 back and forth, adjusting the direction of the nozzle 14 and agitating the tomatoes in different positions inside the rack 3. After agitation, the worker turns off the air pump 4 and turns on the metering pump 16 to continue washing the tomatoes. After washing, the machine casing 1 is opened, the rack 3 is removed, the washed tomatoes are poured out, and the tomatoes are placed back into the machine casing 1 via the rack 3 to continue washing.
