Description

Technical Field

[0001] This utility model relates to a material dryer that facilitates material handling and belongs to the field of mechanical design and manufacturing technology. Background Technology

[0002] In coffee processing, a dryer is often used to quickly evaporate moisture for subsequent processing. Current dryers use a motor-driven central shaft, which in turn rotates a horizontal bar. This horizontal bar then drives several vertical rods and their lifting blocks to agitate the material. Currently, to ensure output and efficiency, the material chamber volume of dryers is enlarged. However, as the shaft rotates with the motor and moves the horizontal bar, it inevitably encounters resistance from the material, causing deformation. This deformation further increases resistance, ultimately requiring the shaft to be replaced every 1-2 months, and sometimes even burning out the motor. This not only increases the need for maintenance and workload but also raises costs for businesses. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0003] To address the problem that the agitator shaft in existing dryers suffers from low service life or even breakage due to the large torque it experiences, this invention provides a material dryer that facilitates material handling.

[0004] This utility model is achieved through the following technical solution: a material dryer for convenient material handling, comprising a shell with an open top and a material cavity inside, characterized in that a hollow vertical cylinder is provided at the center of the material cavity, and upper and lower bearings are provided inside the hollow vertical cylinder. A vertical rotating shaft is provided inside the hollow vertical cylinder and rotatably connected to the upper and lower bearings. The upper end of the vertical rotating shaft is fixed to the middle of a horizontal rod, and the lower end is suspended inside the hollow vertical cylinder. The two ends of the horizontal rod are slidably connected to the edge of the open part of the shell through sliding components. One end of the horizontal rod is connected to a horizontal plate, and the horizontal plate has a through hole. A first bearing is provided in the through hole, and the first bearing rotates with the drive shaft. The drive shaft is connected to a drive wheel at its lower end and to the output shaft of the power unit at its upper end. The drive wheel meshes with a gear ring fixed on the outer wall of the upper end of the housing. When the power unit drives the drive shaft and drive wheel to rotate, the drive wheel rolls along the gear ring on the outer wall of the housing. At the same time, the drive wheel rotates along the gear ring on the outer wall of the housing. The vertical shaft connected in the middle of the horizontal rod is rotated to the upper and lower bearings in the vertical cylinder. This drives the horizontal plate and the horizontal rod to move along the edge of the open end of the housing. This fundamentally solves the problem that the central rotating shaft is prone to deformation, damage, or even motor burnout due to excessive force. It greatly improves the service life of the material dryer and reduces maintenance costs.

[0005] The sliding assembly includes an inverted U-shaped bracket disposed at the other end of the horizontal plate and the horizontal rod. The two vertical plates of the inverted U-shaped bracket extend downward to the inner and outer sides of the upper port wall of the housing. A horizontal short shaft is provided inside the inverted U-shaped bracket, and a roller is provided on the horizontal short shaft. The roller is rolled on the upper port wall of the housing so that the horizontal plate and the horizontal rod can be easily moved along the edge of the housing opening with the help of the roller, thereby further improving the service life of the material dryer and reducing maintenance costs.

[0006] The shell is designed as a vertical cylinder, and the material chamber is located in the upper part of the vertical cylinder. Its shape is adapted to the shape of the shell. A toothed ring is set around the upper outer wall of the shell. A perforated plate is set at the bottom of the material chamber, and a hot air chamber is located below the perforated plate. The hot air chamber is located in the lower part of the vertical cylinder. A hot air inlet is provided on one side of the hot air chamber wall so that hot air can be sent into the hot air chamber through the hot air inlet, and then enter the material chamber from bottom to top through the perforated plate to complete the drying of the material.

[0007] The horizontal bar is provided with multiple vertical bars with lifting plates on them at intervals, so that as it moves with the horizontal bar, the material can be lifted by the multiple vertical bars with lifting plates on them, so that the material can be dried evenly.

[0008] The drive wheel is a gear, which meshes with a gear ring fixed on the outer wall of the upper end of the housing.

[0009] The drive wheel is a sprocket, which meshes with a chain ring fixed to the outer wall of the upper end of the housing.

[0010] This utility model has the following advantages and effects: By adopting the above solution, the drive wheel can easily roll along the toothed ring on the upper outer wall of the shell under the drive of the power machine. At the same time, the vertical rotating shaft connected in the middle of the horizontal rod is rotated and connected to the upper and lower bearings in the vertical cylinder, which drives the horizontal plate and the horizontal rod to move along the edge of the shell opening. In addition, the sliding component is slidably connected to the edge of the shell opening, which fundamentally solves the problem that the central rotating shaft is easily deformed, damaged, or even burns out the motor due to excessive force. This greatly improves the service life of the material dryer, reduces maintenance costs, and enables continuous production. Attached Figure Description

The horizontal bar 6 is provided with multiple vertical bars 10 with lifting plates 9 on them at intervals, so that while moving with the horizontal bar 6, the material can be lifted by the multiple vertical bars 10 with lifting plates 9 on them, so that the material can be dried evenly.
