Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain silo cleaning equipment, in particular to a spiral silo cleaning machine for grain silos. Background Art
[0002] See also Figure 1 The spiral silo cleaning machine is the main equipment for grain silo cleaning operations, including a head transmission device 1, a revolution propulsion device 2, a body support device 3 and an auger shaft 4. The auger shaft 4 has a transmission shaft 5 and spiral blades 6 evenly arranged on the transmission shaft 5. The auger shaft 4 of the existing spiral silo cleaning machine is an equidistant auger shaft, that is, the pitch between the spiral blades 6 on the auger shaft 4 is unchanged, so the spiral space between the spiral blades has the same capacity for conveying grain materials.
[0003] The defects and shortcomings of the existing spiral warehouse cleaning machine are as follows: during the warehouse cleaning operation of the spiral warehouse cleaning machine, since the conveying capacity of the spiral space of each section of the auger shaft 4 is the same, when the rear section spiral space (close to the head transmission device 1) is filled with materials conveyed by the front section spiral (close to the revolution propulsion device 2), the rear section spiral space can no longer receive the materials loaded above it. In other words, the materials above the rear section spiral space are in a stationary state, so the spiral blades of the rear section of the auger shaft are subjected to a large positive pressure, which in turn increases the friction of the materials on the spiral blades, that is, increases the rotational load of the auger shaft. At the same time, during the debonding operation, large-scale collapse of grain materials will occur, completely burying the auger shaft 4 and suffocating the auger shaft.
[0004] Therefore, there is an urgent need to provide a spiral silo cleaning machine for grain silos that has high conveying efficiency and is not prone to stalling. Utility Model Content

[0026] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. In this article, the direction close to the revolution propulsion device is "front", and the direction away from the revolution propulsion device is "rear".
[0027] Embodiment 1:
[0028] This embodiment provides a spiral silo cleaning machine for grain silos, including a head transmission device 1, a revolution propulsion device 2 and a body support device 3.
[0029] The head transmission device 1 is connected to one end of the fuselage support device 3, and the other end of the fuselage support device 3 is connected to the revolution propulsion device 2. A auger shaft 4 is rotatably installed on the fuselage support device 3, and one end of the auger shaft 4 is drivingly connected to the output end of the head transmission device 1.
[0030] The auger shaft 4 is a variable pitch auger shaft, comprising a transmission shaft 5 and a spiral blade 6 arranged on the transmission shaft 5 . The pitch of the spiral blade 6 gradually increases along the direction from the revolution propulsion device 2 to the head transmission device 1 .
[0031] The spiral bin cleaning machine of this embodiment uses a variable pitch auger shaft, which has the advantage of effectively preventing the auger shaft 4 from eating and conveying materials unevenly, ensuring that the materials above each section of the auger shaft 4 are in a flowing state, which reduces the rotational resistance encountered by the spiral blades 6, thereby improving the material conveying efficiency.
[0032] Furthermore, the auger shaft 4 is divided into multiple sections along the length direction, and the transmission shafts 5 of two adjacent sections are detachably connected; the pitches of the spiral blades 6 located on the same transmission shaft 5 are the same, but the pitches of the spiral blades 6 of each section of the auger shaft 4 are different, and the pitches of the spiral blades 6 gradually increase along the direction of the revolution propulsion device 2 toward the head transmission device 1.
[0033] For example, the auger shaft 4 of this embodiment is divided into a first section, a second section and a third section in sequence along the length direction and the direction away from the revolution propulsion device 2. The pitches of the spiral blades 6 on the first section are the same, the pitches of the spiral blades 6 on the second section are the same, and the pitches of the spiral blades 6 on the third section are the same, but the pitch of the spiral blades 6 on the first section is smaller than the pitch of the spiral blades 6 on the second section, and the pitch of the spiral blades 6 on the second section is smaller than the pitch of the spiral blades 6 on the third section.
[0034] Furthermore, the pitch ratio of the first section, the second section and the third section of the auger shaft 4 is 3:2:1. It should be further explained that when the auger shaft 4 is divided into the first section, the second section, the third section and the fourth section in the length direction and the direction away from the revolution propulsion device 2, the pitch ratio of the first section, the second section, the third section and the fourth section is 4:3:2:1. When the auger shaft 4 is divided into the first section, the second section, the third section, ... the nth section in the length direction and the direction away from the revolution propulsion device 2, the pitch ratio of the first section, the second section, the third section, ... the nth section is n: (n-1): (n-2) ...: 2:1.
[0035] Furthermore, the transmission shafts 5 of two adjacent sections of the auger shaft 4 are connected via a clutch 7 , and the clutch 7 is used to form a connection or separation between the two adjacent sections of the auger shaft 4 .
[0036] Embodiment 2:
[0037] This embodiment provides another spiral silo cleaning machine for grain silos. The difference from Embodiment 1 is that in this embodiment, the transmission shafts 5 of two adjacent sections of the auger shaft 4 are connected by a flange.
