It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides a walnut conveying device, as Figures 1 - 4 shown. The walnut conveying device includes: a housing 1; two belt pulleys 2, both of the two belt pulleys 2 are rotatably installed on the housing 1; a conveyor belt 3, the conveyor belt 3 is sleeved on the two belt pulleys 2; a driving motor 4, the driving motor 4 is fixedly installed on the housing 1, and an output shaft of the driving motor 4 is fixedly connected to any one of the belt pulleys 2; a gantry 5, the gantry 5 is fixedly installed on the housing 1 and is arranged above the conveyor belt 3; a support plate 6, the support plate 6 is fixedly installed on the gantry 5; a dispersing mechanism, the dispersing mechanism is arranged on the gantry 5 and the support plate 6 for dispersing walnuts; a cooling mechanism, the cooling mechanism is arranged on the gantry 5 for cooling walnuts.

[0022] In this embodiment, the outer shell 1 serves as the main structure of the entire conveying device, providing support and protection for the internal components to ensure the stability and safety of the device. The rotation of two belt pulleys 2 drives the operation of the conveyor belt 3 to achieve continuous conveying of walnuts. This design is simple and efficient, facilitating maintenance and cleaning. The drive motor 4 serves as the power source, driving the rotation of the belt pulley and then driving the movement of the conveyor belt. The introduction of the drive motor realizes the automatic control of the conveying process. The gantry 5 provides space for installing the dispersion mechanism and the cooling mechanism. The support plate 6 is used to support the dispersion mechanism to ensure its stability during operation. The dispersion mechanism mechanically disperses the walnuts on the conveyor belt to prevent them from sticking tightly, ensuring that heat can dissipate smoothly. This design effectively solves the cooling problem caused by the sticking of walnuts during the conveying process. The cooling mechanism is used to quickly cool the walnuts after dispersion treatment. The cooling mechanism may adopt air-cooling technology to accelerate the dissipation of heat from the surface of the walnuts, creating favorable conditions for subsequent processing. By separating the stuck walnuts through the dispersion mechanism, heat accumulation is avoided, the cooling process is accelerated, and time is saved for subsequent processing. Timely cooling helps to maintain the nutritional components and taste of the walnuts and avoid quality degradation caused by high temperature. The design of the gantry and the support plate enables the dispersion mechanism and the cooling mechanism to be compactly installed above the conveyor belt, saving space and improving the integration of the equipment.

[0023] In a further preferred embodiment of the present utility model, the dispersion mechanism includes a movable rod 7, rake teeth 8, two movable slots 9, a transmission wheel 10, and a driving mechanism. The movable rod 7 slidably penetrates through the gantry 5 and the support plate 6. The rake teeth 8 are fixedly installed at the bottom of the movable rod 7, and the bottom of the rake teeth 8 is in contact with the belt pulley 2. The two movable slots 9 are respectively opened on the gantry 5 and the support plate 6 and are in sliding contact with the movable rod 7 to drive it. The transmission wheel 10 is fixedly installed on the movable rod 7, and the transmission wheel 10 is arranged between the gantry 5 and the support plate 6. The driving mechanism is arranged on the outer shell 1 and is used to drive the rake teeth 8 to move horizontally.

[0024] In this embodiment, the movable rod 7 serves as the main moving component of the dispersing mechanism. The lateral movement of the movable rod 7 drives the movement of the rake teeth 8 fixed to its bottom, thereby realizing the function of dispersing the walnut kernels. The rake teeth 8 are in direct contact with the walnut kernels on the conveyor belt 3. The design of the rake teeth 8 can effectively separate the adhered walnut kernels, prevent them from sticking closely together, and ensure that heat can dissipate smoothly. The movable groove 9 provides guidance and support for the sliding of the movable rod 7. The movable groove 9 ensures the stability and accuracy of the movable rod 7 during movement, avoiding unnecessary shaking or deviation. The transmission wheel 10, through cooperation with the driving mechanism, converts the rotational motion into the linear motion of the movable rod 7, thereby realizing the transverse movement operation of the rake teeth 8. The driving mechanism provides power for the dispersing mechanism, pulls the transmission wheel 10 to move, and further drives the movable rod 7 and the rake teeth 8 to perform transverse movement. Through the precise cooperation of the movable rod 7 and the rake teeth 8, the precise dispersion of the walnut kernels is achieved, effectively avoiding the adhesion and heat accumulation of the walnut kernels. The design of the movable groove 9 ensures the stability of the movable rod 7 during movement, improving the reliability and durability of the dispersing mechanism. The introduction of the dispersing mechanism significantly increases the cooling speed of the walnut kernels, creates better conditions for subsequent processing, and thus improves the overall processing efficiency.

[0025] In a further preferred embodiment of the present utility model, the driving mechanism includes a support frame 11, a connecting plate 12, a traction belt 13, and a reciprocating mechanism. The support frame 11 is fixedly installed on the housing 1. The connecting plate 12 is slidably installed on the support frame 11. The traction belt 13 is sleeved on the transmission wheel 10. The other end of the traction belt 13 is fixedly connected to the connecting plate 12. The reciprocating mechanism is arranged on the support frame 11 and is used to drive the connecting plate 12 to perform reciprocating motion.

[0026] In this embodiment, the support frame 11 provides a stable support platform for the entire driving mechanism. The design of the support frame 11 ensures the stability and reliability of the driving mechanism during operation. The connecting plate 12 can perform reciprocating motion along the guiding structure of the support frame 11. The connecting plate 12 is connected to the transmission wheel 10 through the traction belt 13, realizing the transmission of the power of the reciprocating mechanism to the transmission wheel 10. The traction belt 13, as a key component for power transmission, converts the reciprocating motion of the connecting plate 12 into the linear motion of the transmission wheel 10. The reciprocating mechanism is used to drive the connecting plate 12 to perform reciprocating motion on the support frame 11. Through the combined use of the support frame 11, the connecting plate 12, and the traction belt 13, the stable transmission of power is achieved, ensuring that the dispersing mechanism can work continuously and reliably. The design structure of the driving mechanism is compact, occupies little space, and is easy to install and maintain. The reciprocating mechanism can adjust the reciprocating frequency and amplitude of the connecting plate 12 as needed, thereby controlling the moving speed and distance of the rake teeth 8 to meet different processing requirements. Through the automated reciprocating motion, the manual intervention is reduced, the efficiency of dispersing and cooling the walnut kernels is improved, and thus the overall processing efficiency is enhanced.

[0027] In a further preferred embodiment of the present utility model, the reciprocating mechanism comprises a reciprocating motor 14, a cam 15 and a spring 16. The reciprocating motor 14 is fixedly installed on the support frame 11. The cam 15 is fixedly installed on the output shaft of the reciprocating motor 14. The cam 15 abuts against the connecting plate 12. The spring 16 is fixedly installed on the movable rod 7, and the other end of the spring 16 abuts against the movable groove 9 provided on the gantry 5.

[0028] In this embodiment, the reciprocating motor 14 serves as the power source of the reciprocating mechanism. The reciprocating motor 14 can periodically change the rotation direction of its output shaft or generate a reciprocating rotational torque, thereby driving the cam 15 to perform reciprocating motion. The cam 15 rotates as the output shaft rotates. The contour design of the cam 15 enables it to abut against the connecting plate 12 and push the connecting plate 12 to perform reciprocating motion on the support frame 11 during rotation. In addition to the functions of being slidably installed on the support frame 11 and connected to the traction belt 13 described previously, in this embodiment, the connecting plate 12 directly abuts against the cam 15 and receives the thrust from the cam 15 to perform reciprocating motion. The spring 16 provides a restoring force for the movable rod 7, enabling it to return to the initial position when there is no external force, and at the same time playing a buffering role to reduce the impact and vibration that may occur during the movement of the movable rod 7. By directly driving the cam 15 with the reciprocating motor 14 and then pushing the connecting plate 12 to perform reciprocating motion, the power transmission path is short and direct, improving the energy conversion efficiency. By adjusting the working parameters of the reciprocating motor 14, the reciprocating frequency and amplitude of the connecting plate 12 can be conveniently adjusted, and thus the moving speed and distance of the rake teeth 8 can be controlled.

[0029] In a further preferred embodiment of the present utility model, the cooling mechanism comprises a blower 19, a connecting pipe 20, a tee pipe 21 and two exhaust pipes 22. The blower 19 is fixedly installed on the gantry 5. The connecting pipe 20 is fixedly installed on the exhaust end of the blower 19. The tee pipe 21 is fixedly installed on the connecting pipe 20. Both of the two exhaust pipes 22 are fixedly installed on the tee pipe 21. A plurality of exhaust ports are provided on both of the two exhaust pipes 22, and the plurality of exhaust ports are correspondingly arranged with the conveyor belt 3.

[0030] In this embodiment, the fan 19 serves as the main power source of the cooling mechanism. The fan 19 can generate a strong airflow, which is transported into the exhaust duct 22 through the connecting pipe 20 and the three-way pipe 21, and finally blown onto the walnuts on the conveyor belt 3 to achieve the cooling effect. The connecting pipe 20 is used to direct the airflow generated by the fan 19 to the three-way pipe 21. The design of the connecting pipe 20 ensures the smooth transmission of the airflow and reduces energy loss. The three-way pipe 21 plays a role in splitting the flow. The three-way pipe 21 divides the airflow from the connecting pipe 20 into two paths and transports them into the two exhaust ducts 22 respectively, so that the airflow can evenly cover the walnuts on the conveyor belt 3. The multiple air outlets opened on the exhaust duct 22 enable the airflow to evenly blow onto the walnuts on the conveyor belt 3 to achieve effective cooling. The number and position of the air outlets are carefully designed to maximize the cooling effect. The number and size of the air outlets are adjusted according to actual needs to ensure that the airflow can directly blow onto the walnuts to achieve the best cooling effect. The design of the exhaust duct 22 enables the airflow to evenly cover the walnuts on the conveyor belt 3, avoiding local overheating or overcooling and ensuring the uniformity of cooling.

[0031] In a further preferred embodiment of the present utility model, a fixing block 17 is fixedly installed at the top of the movable rod 7. The fixing block 17 is arranged above the gantry 5 and is wider than the width of the movable slot 9. Two pulleys 18 are rotatably installed in the fixing block 17, and both of the two pulleys 18 are in sliding contact with the top of the gantry 5.

[0032] In this embodiment, the width of the fixing block 17 is designed to be wider than the width of the movable slot 9. The main purpose of this is to increase the stability of the movable rod 7 during movement and prevent it from shifting or shaking due to lateral forces. The pulleys 18 are in sliding contact with the top of the gantry 5. When the movable rod 7 moves horizontally under the drive of the reciprocating mechanism, the pulleys 18 will roll along the top of the gantry 5, thereby reducing the frictional resistance between the movable rod 7 and the gantry 5 and making the movement of the movable rod 7 smoother and more stable. The design of the fixing block 17 increases the stability of the movable rod 7 during movement, prevents offset or shaking caused by lateral forces, and ensures that the dispersing mechanism can accurately perform its work tasks. The introduction of the pulleys 18 effectively reduces the frictional resistance between the movable rod 7 and the gantry 5, makes the movement of the movable rod 7 smoother and more stable, reduces energy consumption and extends the service life of the equipment.

[0033] In a further preferred embodiment of the present utility model, a tensioning wheel is rotatably installed in the housing 1, and the tensioning wheel abuts against the conveyor belt 3.

[0034] In this embodiment, the tension pulley is rotatably installed in the housing 1, and its specific position is usually selected on the circulation path of the conveyor belt 3 so as to contact the conveyor belt 3. The main function of the tension pulley is to adjust the tension of the conveyor belt 3, ensure that the conveyor belt 3 maintains an appropriate tight state during operation, and avoid problems such as slipping, deviation, or increased wear caused by slack. By adjusting the position or pressure of the tension pulley, the tension of the conveyor belt 3 can be effectively controlled, ensuring the stability and reliability of the transmission. The introduction of the tension pulley enables the tension of the conveyor belt 3 to be precisely adjusted, thereby improving the stability of the transmission process and reducing failures caused by insufficient or excessive tension. The design of the tension pulley makes the operation of the conveyor belt 3 smoother, reduces energy consumption losses caused by tension problems, and optimizes the overall performance of the device.

[0035] In summary, compared with the related technology, through the designed dispersion mechanism, using the transverse movement of the movable rod and the rake teeth, the walnuts that are adhered tightly together are effectively separated, avoiding the problem of heat accumulation caused by adhesion and improving the cooling efficiency of the walnuts. The equipped cooling mechanism uses the airflow generated by the fan and directly blows it onto the walnuts on the conveyor belt through the air outlets on the exhaust duct, achieving rapid cooling of the walnuts and maintaining the nutritional components and taste of the walnuts. The combined action of the dispersion mechanism and the cooling mechanism not only solves the problems of adhesion and heat accumulation during the transportation of walnuts, but also accelerates the cooling process of walnuts, saves time for subsequent processing, and significantly improves the overall processing efficiency. The overall device has a compact structure design, the components cooperate closely with each other, occupy a small space, and are convenient for installation and maintenance, reducing the use cost. By adjusting the relevant parameters of the reciprocating mechanism and the cooling mechanism, the moving speed and distance of the rake teeth and the wind speed of the fan can be easily controlled to meet different processing requirements, enhancing the adaptability and flexibility of the device.
