Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical manufacturing, in particular to a lifting base and a pellet heater. BACKGROUND

[0002] The pellet heater is a heating device using compressed wood chips and other biomass pellets as fuel, which is widely used in homes, offices and other places in recent years. After the biomass pellets enter the hearth, the organic matter in the pellets will undergo oxidation reaction under sufficient oxygen supply, releasing heat energy.

[0003] The moving and braking functions of the current courtyard heater mainly rely on two types of technical designs. One type of design is to install two rollers flush with the ground at the rear of the product base. When the device needs to be moved, the entire machine needs to be tilted backward until the base is completely separated from the ground, so that the two rollers are independently stressed and in contact with the ground, and then the moving operation is completed by pushing. This design can meet the basic moving needs, but has significant use limitations. Not only is the tilting operation of the entire machine cumbersome, but the upper part of the product, which is the core heat dissipation area, always maintains a high temperature, posing a safety risk when directly contacted during moving. Another type of design uses four casters with brake mechanisms on the base to achieve the movement and fixation of the device by adjusting the brake state of the casters. However, this design lacks in operation convenience, as at least two or even all four casters need to be manually adjusted, making the operation process relatively cumbersome. It is worth noting that both designs have the common problem of exposed casters, which affects the overall appearance and aesthetics of the product.

Therefore, the operator only needs to apply a force to the transmission rack 11 to make it reciprocally slide, which can drive the lifting unit to act. In actual application, the transmission gear and the support shaft 9 can be connected by key connection to ensure the smooth transmission of power.

[0031] In the embodiment, the toothed cam 10 has a gear part and a cam part, the gear part is engaged with the transmission gear and the transmission rack 11 respectively, the cam part is abutted with one of the first support rod 5 and the second support rod 6, the toothed cam 10 ensures the smooth transmission of power while providing support for the first support rod 5 or the second support rod 6 abutted with the cam part, thereby improving the structural stability of the lifting unit.

In order to avoid the influence of the base shell 1 on the action of the driving assembly, an opening can be arranged on the side of the base shell 1 close to the driving assembly, so as to ensure the normal use of the linkage rod 13 and the operating rod 14. In addition, a buckle 15 can be arranged on the heater body 200, the buckle 15 can be connected with the operating rod 14 by clamping, when the operating rod 14 is not working, the operating rod 14 can be adjusted to the direction close to the heater body 200, and the operating rod 14 is clamped with the buckle 15, so as to facilitate the fixation of the operating rod 14, further reduce the occupied space of the lifting base 100, and improve the flexible adaptability of the lifting base 100.

[0037] In actual application, the linkage rod 13 can also be directly pulled to drive the lifting unit. In addition, in other specific embodiments that can be implemented by the present application, a motor driving mode can also be adopted, a motor is used to drive the transmission gear to rotate, thereby driving the lifting unit to perform lifting action; or a hydraulic cylinder is used to drive the transmission rack 11 to reciprocate and slide, which can also drive the lifting unit to realize the lifting purpose.

[0038] Further, in order to improve the convenience of the heater body 200, the walking wheel 4 can be selected as a universal wheel with a brake, which improves the moving efficiency of the particle heater and is also conducive to improving the safety of the transfer operation.

[0039] Embodiment two The embodiment provides a particle heater, which comprises a heater body 200 and the lifting base 100 described above, and the heater body 200 is detachably connected with the base shell 1.

[0040] The heater body 200 can be "lifted up" by using the lifting base 100, and then the heater body 200 is moved by using the walking wheel 4, which improves the moving operation convenience of the particle heater and reduces the labor burden of the operating personnel.

When the particle heater does not need to be carried, the distance between the upper frame 2 and the lower frame 3 is small, the base shell 1 is in contact with the ground, and the walking wheel 4 is not in contact with the ground.

[0043] It should also be explained here that the number of walking wheels 4 can be set to multiple, and the number and distribution of walking wheels 4 can be adjusted according to the shape and specifications of the lower frame 3 to improve the stress uniformity of the lifting base 100 and improve the moving safety factor of the heater body 200.

[0044] The lifting base 100 of the present application has a simple and compact structure, can be conveniently connected with the heater body 200, and when not in use, the connection components are all located in the base shell 1, ensuring the aesthetics of the particle heater.
