Description

Technical Field

[0001] This utility model belongs to the field of peanut processing technology, and more specifically, it relates to a high-efficiency transmission device for a peanut oil press. Background Technology

[0002] This peanut oil press is specifically designed for peanut raw materials. Utilizing screw pressing or hydraulic technology, it efficiently extracts peanut oil through physical pressing, preserving its natural nutrients and aroma. The main body of the equipment consists of a pressing chamber, motor, and oil filtration system. It is easy to operate and achieves an oil yield of 40%-50%. It supports both cold and hot pressing modes; cold pressing preserves the original aroma, while hot pressing increases oil output. Intelligent temperature control prevents scorching, ensuring pure oil quality. The machine is robust and durable, suitable for family workshops, small oil mills, and food processing plants. It is also energy-efficient, environmentally friendly, and easy to clean and maintain, making it an ideal piece of equipment for producing high-quality peanut oil.

[0003] While peanut oil presses can improve pressing efficiency, their supporting operational processes still have significant shortcomings: before oil pressing, a separate peanut shelling machine is required to mechanically crush the shelled raw material and separate the shells from the kernels; after shelling, operators need to manually transport or use simple conveying equipment to transfer the shelled peanut kernels from the shelling station to the oil press's feed inlet. This process involves switching between equipment start-ups and shutdowns, multiple loading and unloading of materials, and repeated adjustments to equipment parameters to adapt to different operational needs. This fragmented operational mode not only leads to a disjointed operational process but also increases labor costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a high-efficiency transmission device for peanut oil presses, in order to achieve a more practical purpose. Utility Model Content

[0011] Preferably, the rotating shaft is installed in the shelling bin, the collecting bin and the blower bin, and is fixedly connected to the conical roller and the blower respectively, and is also rotatably connected to the guide plate. The bottom end of the rotating shaft passes through the bottom side of the rotating shaft and is fixedly fitted with a first pulley. The first pulley is located in the middle of the hopper, and the bottom middle of the first pulley is fixedly connected to the top middle of the internal transmission shaft of the oil press.

[0015] 2. This utility model of a conical concave plate screen achieves uniform dehulling through the progressive extrusion action of the dehulling ribs on the outer wall of the conical drum, reducing the breakage rate. It is suitable for the industrial processing of mainstream peanut varieties. The blower chamber efficiently separates shell fragments from peanut kernels through negative pressure airflow.

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a high-efficiency transmission device for a peanut oil press, including an oil press 1 and a transmission mechanism 2. The feed end of the oil press 1 is provided with a hopper 3, which is connected to a shell-breaking mechanism 4 through the transmission mechanism 2. The shell-breaking mechanism 4 includes a shelling chamber 401, a collection chamber 402, a blower chamber 403, and a rotating shaft 404. The shelling chamber 401 is provided with a conical roller 4011 and a conical concave sieve 4012. The outer wall of the conical roller 4011 is provided with spirally distributed shelling ribs 4013 for pressing and shelling peanuts with shells. The collection chamber 402 is provided with a guide plate 4021 and a kernel outlet 4022. The guide plate 4021 is inclined to guide the shelled peanut kernels into the kernel outlet 4022. The blower chamber 403 is provided with a blower 4031 and a debris discharge port 4032. The blower 4031 is connected to the collection chamber 402 through an air duct 4024 for separating shell debris from peanut kernels.

[0027] The shelling chamber 401 is connected to a feeding hopper, and a flow regulating plate 5 is slidably installed between the feeding hopper and the shelling chamber 401 to control the feeding speed of peanut raw materials. By adjusting the feeding speed, the flow rate of peanut raw materials can be precisely controlled to avoid blockage or excessive feeding, thereby improving shelling efficiency and equipment stability.

[0028] Among them, the kernel outlet 4022 of the collection bin 402 is hinged with a sealing plate 4023, which is used to adjust the opening and closing of the kernel outlet 4022. The hinged design makes it easy to flexibly open and close the kernel outlet 4022, adjust the discharge rhythm, reduce accumulation or instantaneous overload, and ensure the smooth and continuous operation of subsequent oil pressing processes.

[0029] The blower chamber 403 has a detachable filter screen at its discharge port 4032, which is used to intercept small impurities and prevent them from entering the oil press 1.

[0030] The surface of the guide plate 4021 is provided with an anti-stick coating made of polytetrafluoroethylene, which is used to reduce the residue of peanut kernels during the guide process.

[0031] The rotating shaft 404 is installed in the shelling chamber 401, the collecting chamber 402 and the blower chamber 403, and is fixedly connected to the cone roller 4011 and the blower 4031 respectively. It is also rotatably connected to the guide plate 4021. The bottom end of the rotating shaft 404 passes through the bottom side of the rotating shaft 404 and is fixedly fitted with the first pulley. The first pulley is located in the middle of the hopper 3, and the bottom middle of the first pulley is fixedly connected to the top middle of the internal transmission shaft of the oil press 1.

[0032] The transmission mechanism 2 includes a transmission shaft that is rotatably installed inside the oil press 1.

[0033] The working principle of this embodiment is as follows: Feed control: Peanuts in shells enter the shelling mechanism 4 through the hopper 3. The flow regulating plate 5 adjusts the feeding gap between the feeding hopper and the shelling chamber 401 by sliding to control the flow rate of the peanut raw material and avoid material overload. The outer wall of the conical roller 4011 in the shelling chamber 401 is provided with spiral shelling ribs 4013, which rotate under the drive of the rotating shaft 404 and form a squeezing effect with the conical concave plate screen 4012 to separate the peanut shells from the kernels. The fixed gap design combined with the progressive squeezing of the spiral ribs ensures high shelling efficiency and low breakage rate. The shelled mixture enters the collection chamber 402. The guide plate 4021 is set at an inclination to guide the peanut kernels to slide towards the kernel outlet 4022. At the same time, the fan 40 in the fan chamber 403... 31. Negative pressure airflow is generated through the air duct 4024, which draws shell fragments into the impurity discharge port 4032. A detachable filter screen intercepts fine impurities. The hinged sealing plate 4023 at the kernel outlet 4022 can adjust the opening and closing degree to control the flow rate of peanut kernels into the oil press 1 and avoid blockage. The polytetrafluoroethylene anti-stick coating on the surface of the guide plate 4021 reduces residue. The transmission mechanism 2 drives the second pulley to rotate through the motor. The belt connects the second pulley and the first pulley, driving the rotating shaft 404 to rotate synchronously. This drives the conical roller 4011 and the blower 4031 to work together. The shelled peanut kernels directly enter the pressing chamber of the oil press 1 through the kernel outlet 4022 to complete the oil pressing operation, realizing a seamless connection of the entire process of shelling, sorting and pressing.
