[0006] The correction mechanism also includes an adjustment bolt and a correction plate. A screw hole that matches the adjustment bolt is located in the middle of the crossbeam, and the bottom of the adjustment bolt is rotatably connected to the correction plate. The bottom surface of the correction plate has an arc-shaped groove that matches the outer wall of the shaftless spiral blade. The correction mechanism located on each set of crossbeams provides segmented position control for the shaftless spiral impeller. The correction plate presses down on the shaftless spiral impeller to correct it, preventing the area near the free end from tilting during operation. This prevents the shaftless spiral impeller from tilting and causing curvature, which could affect equipment processing.

[0007] Preferably, the angle of the arc groove is not less than 75 degrees. Through the contact area between the arc groove and the shaftless spiral blade, the correction plate can stabilize the working state of the shaftless spiral blade when working.

[0008] Preferably, a limiting rod is provided on the top surface of the correction plate, and a hole adapted to the limiting rod is provided on the crossbeam.

The retaining slot is L-shaped, and the top surface of the housing is provided with a connecting slot. The top surface of the cover plate is provided with a waist-shaped calibration hole, and the calibration hole and the connecting slot are connected by connecting bolts. The cooperation between the retaining block and the retaining slot at the bottom of the cover plate enables the cover plate to be quickly installed on the housing, reduces the use of bolts, and facilitates subsequent maintenance without affecting normal use.

[0010] Preferably, the bottom surface of the blocking block is semicircular or conical.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] The utility model uses a correction mechanism provided on each group of cross beams to limit the shaftless spiral impeller in sections.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Reference Figure 1-5 The shown embodiment is a shaftless spiral feeding device for a furnace feeding system, comprising a shell 1, a T-shaped connector 3 being rotatably connected to the end of the shell 1, one end of the connector 3 being connected to one end of a shaftless spiral blade 4, and the other end being connected to a driving source 2 on the outer wall of the shell 1, thereby achieving the purpose of driving the internal shaftless spiral blade 4 to rotate, a crossbeam 9 being designed on the inner wall of the shell 1, the purpose of which is to strengthen the structural strength of the entire shell 1; and a correction mechanism being provided on the crossbeam 9, the purpose of which is to perform a limit correction on the shaftless spiral blade 4 during operation, to prevent the free end from warping during use, causing the shaftless spiral blade 4 to produce an arc, thereby increasing equipment loss; the connection method between the cover plate 5 and the shell 1 is convenient and fast, saving time and effort, compared with the existing fixing method using multiple sets of bolts.

[0023] Correction mechanism: The crossbeam 9 is provided with a screw hole for the threaded lifting and lowering of the adjusting bolt 10, and the bottom end of the adjusting bolt 10 is rotatably connected to the correction plate 11 bracket, so that when the adjusting bolt 10 is lifted and lowered on the crossbeam 9, the correction plate 11 is controlled to press down to limit the shaftless spiral blade 4. In order to prevent the correction plate 11 from rotating during the lifting process and causing eccentricity, a limiting rod 12 for positioning is provided on the top surface of the correction plate 11, and a hole adapted to the limiting rod 12 is provided on the crossbeam 9 so that the limiting rod 12 can be lifted and lowered to achieve the purpose of limiting the correction plate 11.

[0024] The arc groove at the bottom of the correction plate 11 has the same diameter as the shaftless spiral blade 4, and the minimum angle of the arc groove is 75 degrees (and the length of the correction plate 11 is greater than the distance between the two blades). The contact area between the two ensures that when the correction plate 11 is pressed down, the shaftless spiral blade 4 can be in a stable working state.

[0025] The top of the adjusting bolt 10 is provided with a hexagonal groove, and the hexagonal groove is provided with through holes running through it on the left and right. The purpose of its structure is to provide multiple driving modes. When a suitable hexagonal rotating adjusting bolt 10 cannot be found, a stick-shaped tool can be temporarily used to drive the adjusting bolt 10 to rotate.

[0026] An L-shaped slot 101 and a connecting slot 102 are provided on the top surface of the shell 1, which are respectively matched with the L-shaped blocking block 6 and the calibration hole 7 at the bottom of the cover plate 5; after the blocking block 6 is inserted into the blocking slot 101, the cover plate 5 is pushed to the right to complete the matching between the blocking block 6 and the blocking slot 101, thereby realizing basic positioning, and then the calibration hole 7 and the connecting slot 102 of the waist-shaped structure are aligned, and the cover plate 5 is fixed to the shell 1 using the connecting bolts 8, and a feed port is provided on the top of the cover plate 5 at the feed port; through the cooperation between the above structures, while reducing the usage rate of the bolts, it does not affect its installation stability and structural strength, and at the same time reduces the time required for subsequent maintenance and updates.

[0027] The semicircular structure design at the bottom of the locking block 6 allows the cover plate 5 to be quickly inserted into the locking slot 101 during installation, thereby improving installation efficiency.

[0028] The working principle of this utility model is as follows: by starting the driving source 2, it drives the shaftless spiral blade 4 to rotate inside the shell 1 through the connecting head 3, and the material entering from the feed port is transported step by step to the discharge port with the cooperation of the above structure. During use, in order to prevent the shaftless spiral blade 4 from tilting, the adjusting bolt 10 is rotated to make the adjusting bolt 10 rise and fall on the beam 9, and drive the correction plate 11 connected to the bottom rotation to rise and fall. Under the limit of the limit rod 12, the correction plate 11 can perform normal lifting and lowering movements, and firmly press the shaftless spiral blade 4 so that it can operate normally.

[0029] When maintenance or replacement is required, rotate the connecting bolt 8 so that the bottom of the connecting bolt 8 comes out of the connecting groove 102 and the calibration hole 7, then push the cover 5 to the left to stagger the positioning block 6 and the slot 101, then lift the cover 5 upwards to complete the separation of the cover 5 and the shell 1. When installing, just do the opposite operation.

[0030] The electromechanical connection involved in the present invention is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, which belongs to common knowledge.

[0031] Components not described in detail herein are prior art.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
