However, in the actual unloading process of the silo, not only the phenomenon that the loose particles cannot be completely discharged, but also abnormal phenomena such as blockage often occur. This blockage is mainly due to the fact that the loose particles are easy to form an arch structure.

At present, the sports arching method is a commonly used method of breaking arches. The motion arching method is to set a moving part (moving arm or blade) inside the silo, and the moving parts are driven by the speed reducing motor, and the arching structure of the bulk granular material is destroyed by the rotation or movement of the moving part, and the moving part is dispersed. The body particles move toward the discharge port and are discharged.

Embodiment 1:

Figure 1 is a schematic view showing the structure of an embodiment of the arch unit of the present invention;

As shown in FIG. 1 , the arch unit 100 of the present invention includes a connecting rod 110; the connecting rod 110 is pivotally connected with one or more connecting members 120 in the axial direction, and at least one cantilever end 121 of the connecting member 120 A skip arm 130 is connected; the skip arm 130 is disposed at an angle with the connecting rod 110; when the connecting rod 110 moves in the axial direction, the cantilever end 121 of the connecting member 120 is opposite to the connecting member under the arching resistance 120 and the pivot point 122 of the connecting rod 110 are angularly displaced to adjust the arching resistance of the skip arm 130.

The working principle of the present invention is that the arching unit 110 moves in the axial direction during the arching process. The connecting rod 110 drives the skip arm 130 to reciprocate axially through the connecting member 120, and the skip arm 130 disperses. The body material moves toward the discharge port and is discharged through the discharge port. When the arching resistance of the picking arm 130 is changed during the movement, the cantilever end 121 of the connecting member 120 connected to the skip arm 130 rotates around the pivoting point 122, and the picking arm 130 is generated relative to the connecting rod 110. Angular displacement, avoiding arching along the edge of the arch. The arching unit of the present invention can largely avoid the arching resistance, and the rigidity of the skip arm 130 is effectively avoided.

Under normal circumstances, each time the pivoting arm 122 rotates about the pivoting point, the arching edge is rubbed away from the arching portion, and the arching portion is subjected to a breaking force. In the case where the skip arm 130 is reciprocating, it is inevitable to apply a plurality of arching disturbances to the arching portion to achieve the purpose of arching. The arching effect of the arch unit of the present invention is thus greatly enhanced.

In the embodiment shown in Figures 1 and 1A, the connector 120 is formed by a curved rod 123. At least one end of the curved rod 123 constitutes a cantilever end 121 to which the skip arm 130 is attached. The skip arm 130 is disposed at an angle of 90 degrees or nearly 90 degrees with respect to the link 110. The skip arm 130 can form a larger dialing surface during the movement.

In this embodiment, the curved rod 123 is pivotally connected to the connecting rod 110. When the arching resistance is too large, the curved rod 123 rotates around the pivoting point 122 to drive the cantilever end 121 to connect with the curved rod 123. The pivotal portion 122 of the rod 110 is angularly displaced, avoiding the arched material along the edge of the arch and simultaneously damaging the arched material from the edge of the arch. Since the skip arm 130 reciprocates with the link 110, the skip arm 130 is reversely rotated and pivoted around the pivot point 122 during the return movement of the skip arm 130. During the reciprocating motion of the skip arm 130, the arching is continuously subjected to multiple arching disturbances, thereby achieving an excellent arching effect. Specifically, in this embodiment, since the curved rod 123 itself has a certain amount of elastic deformation, therefore, when When the arching resistance is too large, the curved rod 123 will also have a certain elastic deformation, which further increases the adjustment amount of the arching resistance of the skip arm 130 connected to the curved rod 123, thereby preventing the dialing from being maximized. The rigidity of the arm 130 is broken.

In an embodiment of the present embodiment, as shown in FIG. 1A, the connecting member 120 is formed by a curved rod 123 which is substantially parallelly connected with respect to the connecting rod 110, and the curved rod 123 The arc arch position is pivotally connected to the connecting rod 110, and the two cantilever ends 121 of the curved rod 123 are respectively connected with the skip arm 130. When the link 110 reciprocates, the pair of skip arms 130 reciprocate accordingly.

A preferred embodiment of the present embodiment is shown in Figs. 1 and 1B. This embodiment employs a pair of curved rods 123. The plane in which the curved rod 123 is located is disposed in parallel with respect to the link 110. The arcuate position of the curved rod 123 is pivotally connected to the connecting rod 110, and the two cantilever ends 121 are respectively connected with the skip arm 130. The structural design of a pair of parallel curved rods 123 can increase the strength of the curved rods 123 to make them less susceptible to damage.

In the embodiment shown in FIG. 1B , one end of the curved rod 123 is pivotally connected to the connecting rod 110 , and the other end of the cantilever end 121 is pivotally connected to the skip arm 130 .

In the present embodiment, the arcuate rod 123 constituting the connecting member 120 is mainly used during the movement, and the cantilever end 121 is easily rotated at the pivotal point with respect to the connecting rod 110 when the arching resistance is increased, and the curved rod 123 is coupled. The elastic deformation of the material itself enables the material arm 130 to elastically avoid the arching point during the rotation process, so as to avoid the purpose of avoiding the rigidity of the material arm 130. Therefore, the shape of the curved rod 123 is not limited by the shape shown in the above embodiment.

As shown in FIG. 2 , in the embodiment, the connecting member 120 is formed by a straight rod 124 . One end of the straight rod 124 is pivotally connected to the connecting rod 110 , and the other cantilever end 121 is connected to the skip arm 130 . When the skip arm 130 encounters an increase in arching resistance, the straight rod 124 rotates about the pivot point 122, and the cantilever end 121 of the straight rod 124 is angularly displaced relative to the pivot point 122 of the rod 110. During the reciprocating movement of the skip arm 130, the straight rod 124 is again rotated in the opposite direction about the pivot point 122. Due to the repeated rotation of the skip arm 130, the arching force is continuously applied to the arching member until the material is pushed to the output mechanism after the arching is broken.

Implementation of the broken arch unit 2:

As shown in FIG. 3, the second embodiment of the present invention is substantially the same as the previous embodiment, except that the skip arm 130 and the connecting member 120 are pivotally connected in the moving plane of the skip arm 130. The other end of the skip arm 130 forms a free end 131 that is rotatable about a pivot point 137 that constitutes rotational freedom in different planes of the draw arm 130. When the arching state of the material in the silo is serious, and the large arching resistance encountered by the skip arm 130, the free end 131 of the skip arm 130 rotates around the pivot point 137 to avoid the arch. The throwing arm 130 is added with a degree of rotational freedom to fundamentally prevent the rigidity of the skip arm 130 from being broken. At the same time, the free end 131 of the skip arm 130 effectively perturbs the arch bridge during the rotation avoidance process. During the reciprocating movement of the skip arm 130, the arch bridge is continuously disturbed by the arch. The arch bridge is opened after multiple disturbances to achieve a better arching effect. The embodiment can achieve the increase of the material The optimum effect of the adjustment range of the arching resistance of the arm 130 ensures that the breakage rate is minimized.

Specifically, in the present embodiment, the connecting member 120 is constituted by a pair of curved rods 123. Each of the curved rods 123 is pivotally connected to a skip arm 130. One end of the skip arm 130 is pivotally connected to the curved rod 120, and the other end constitutes a free end rotatable about the pivot point.

In another optional embodiment of the second embodiment, the two ends of the skip arm 130 are pivotally connected to the connecting member 120, so that the skip arm 130 forms two pivoting points 137. Free end. Specifically, in the embodiment, the connecting member 120 is formed by a curved rod 123. Each of the cantilever ends 121 of the curved rod 123 is pivotally connected with a skip arm 130. The pivot point 137 is between the two ends of the skip arm 130, and the skip arm 130 is rotatable about the pivot point 137.

In still another alternative embodiment of the present embodiment, the skip arm 130 includes a fixed arm 134 connected to the connecting member 120 and a disturbing arm 135 pivotally connected to the fixed arm 134. The disturbing arm 135 constitutes a dialing The free end 131 of the arm. Specifically, in the embodiment, the connecting member 120 is formed by a pair of arc-shaped rods 123 arranged in parallel. The curved rods 123 are connected to the fixed arms 134. The two ends of the holding arms 134 are respectively connected with the disturbing arms 135.

In the embodiment, an elastic returning element 140 is connected between the disturbance arm 135 and the fixed arm 134. When the skip arm 130 is in motion, the skip arm 130 is difficult to reset under the condition that the displacement is large, or the arching condition is complicated, and the arm 130 can be reset by the elastic restoring element 140.

As shown in FIG. 3 and FIG. 3A, in the embodiment, the elastic restoring element 140 is formed by a tension spring 141, and the free end 131 of each of the skip arms 130 is correspondingly provided with an elastic reset formed by the tension spring 141. Element 140.

As shown in FIG. 3B, the elastic returning element 140 in this embodiment can be constituted by a torsion spring 142, and the two extended twisting arms of the torsion spring 142 are respectively engaged with the fixed arm 134 and the disturbing arm 135. When the skip arm 130 reciprocates with the link 110, the disturbing arm 135 of the skip arm 130 rotates under the action of arching resistance, effectively avoiding the arching ridge. The disturbance arm 135 of the draw arm 130 is then reset by the torsion spring 142.

Other types of elastic members known to those skilled in the art may be employed for the elastic returning member 140 in the present embodiment.

As shown in FIGS. 4A and 4B, the skip arm 130 of the present invention may be in the shape of a spade. Of course, the dip arm 130 may also be of a flat type or other form familiar to those skilled in the art.
