[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] As Figure 1 and Figure 2 shown, the present invention provides an implementation manner of a feeding cylinder, including a cylinder body 1, a blocking member 2, and a limiting member 3.

[0051] Among them, the cylinder body 1 is used to contain materials. Openings are provided at the top and bottom of the cylinder body 1. Among them, the opening at the top of the cylinder body 1 is a feeding port 11, and the opening at the bottom of the cylinder body 1 is a discharging port 12.

[0052] In this implementation manner, the shape of the cylinder body 1 is not limited, and it can be a cylinder or a polygonal column.

[0053] Among them, the blocking member 2 is arranged at the discharging port 12 of the cylinder body 1; and the blocking member 2 can completely cover the discharging port 12 to close the discharging port 12. The blocking member 2 is used to block the materials in the cylinder body 1 from falling outside the cylinder body 1 through the discharging port 12; and the blocking member 2 can move away from the discharging port 12 to open the discharging port 12 to realize discharging.

[0054] In this implementation manner, the specific structure and quantity of the blocking member 2 are not limited, nor is the position; in this implementation manner, the blocking member 2 can move under the action of the gravity of the materials to open the discharging port 12, or the blocking member 2 moves under its own gravity to open the discharging port 12, or the blocking member 2 moves under an external force to open the discharging port 12.

[0055] Among them, the limiting member 3 can act on the blocking member 2 to limit the movement of the blocking member 2 away from the discharging port 12, and the limiting member 3 can be released from the limiting effect on the blocking member 2.

[0056] In this implementation manner, the specific structure of the limiting member 3 is not limited. Specifically, it can be in contact with the blocking member 2 and exert a restriction on the blocking member 2 to prevent the blocking member 2 from separating from the discharging port 12, so that the discharging port 12 remains in a closed state; at the same time, the blocking member 2 is a movable structure and can move under an external force to release the restriction on the blocking member 2, so that the blocking member 2 can be moved to open the discharging port 12, and the materials in the cylinder body 1 fall from the discharging port to realize discharging.

[0057] There is no limit to the number of limit members 3, and at least one set of limit members 3 is provided corresponding to each blocking member 2. In order to ensure the stability of the force applied to the limit members 3, two sets of limit members 3 can be symmetrically arranged for each blocking member 2.

[0058] This embodiment provides an example of the blocking member 2, as Figure 2 shown:

[0059] The blocking member is a double-door structure composed of two door panels 23; the door panels 23 are hinged to the edge of the discharge port 12; wherein, when the two door panels 23 are in the closed state, they completely cover the discharge port 12, and the joint between the blocking member 2 and the discharge port 12 is completely closed.

[0060] Furthermore, in order to ensure the sealing performance at the gap between the two door panels 23 in the closed state, in this embodiment, one of the door panels 23 extends towards the gap in the direction of the edge near the gap between the two door panels 23 to form a retaining strip 22, and the retaining strip 22 covers the above-mentioned gap to prevent the material in the cylinder 1 from leaking through the gap.

[0061] Furthermore, in this embodiment, a first torsion spring 21 sleeved on the hinge shaft is also connected between the door panel 23 and the discharge port 12. The two ends of the first torsion spring 21 act on the cylinder 1 and the door panel 23 respectively. The first torsion spring 21 applies a torsion force to the door panel 23 to make the door panel 23 close relative to the discharge port 12, so that the two door panels 23 have a driving force to close themselves.

[0062] And the torsion force of the first torsion spring 21 is such that the two door panels 23 can return to the state of closing the discharge port 12 in the open state without any restrictive action.

[0063] In this embodiment, when the gravity of the material inside the cylinder 1 is greater than the torsion force of the first torsion spring 21, the door panel 23 will flip downward (open the door panel 23), and the material in the cylinder 1 will fall from the discharge port 12. In order to avoid the above situation, this application provides an example of the limit member and an example of the contact part on the door panel with the limit member, as Figure 3 shown:

[0064] The door panel 23 extends outward to the outside of the cylinder 1 to form a limit plate 24. One end of the limit member 3 can abut against the limit plate 24 to limit the opening movement of the door panel 23, and the end of the limit member 3 can be offset from the limit plate 24 under the action of an external force.

[0065] Furthermore, a slot 25 is provided on the side of the limit plate 24. One end of the limit member 3 forms an insertion part 31 that can be inserted into the slot 25, and the other end is a connecting part 32. The connecting part 32 is arranged on the side of the cylinder 1 through a rotating shaft 35, and the limit member 3 can rotate around the rotating shaft 35; the insertion part 31 of the limit member 3 can be disengaged from the slot 25 as the limit member 3 rotates.

[0066] In this embodiment, the limiting member 2 is vertically arranged, and a bracket 13 is horizontally arranged at the lower position of the outer side wall of the cylinder body 1. The limiting member 2 is rotatably connected to the bracket 13, and the rotation plane of the limiting member 3 intersects the door panel 23; wherein, the connecting portion 32 is located at the top of the limiting member 2, and the inserting portion 31 is located at the bottom of the limiting member 2.

[0067] When discharging is required, an external force is applied to the limiting member 3, so that the limiting member 3 rotates along the direction in which its bottom faces away from the door panel 23, so that the inserting portion 31 disengages from the slot 25 of the door panel 23. The door panel 23 loses its restriction, and the door panel 23 will open downward under the combined action of its own gravity and the gravity of the material, realizing discharging.

[0068] If the sum of its own gravity and the gravity of the material is less than the torsion force of the first torsion spring 21, even if the door panel 23 loses its restriction, it is not enough to cause the door panel 23 to flip downward. Then, while applying an external force to the limiting member 3, it is also necessary to apply a downward pressure to the edge of the door panel 23, so that the door panel 23 opens downward, realizing discharging.

[0069] In view of the above situation, in order to facilitate opening the door panel 23, the directions of the external force applied to the rod body 34 and the external force applied to the door panel 23 are the same.

[0070] Therefore, in this embodiment, a stress portion 33 is formed by extending the side of the connecting portion 32 facing the cylinder body 1. Under the action of the downward external force, the stress portion 33 can make the limiting member 3 rotate along the direction in which its bottom faces away from the door panel 23, so that the inserting portion 31 disengages from the slot 25.

[0071] And there is a space for applying an external force above the stress portion 33; similarly, there is also a space for applying an external force above the edge of the door panel 23.

[0072] Furthermore, a second torsion spring 34 is arranged on the rotating shaft 35, and the second torsion spring 34 is set to always have a torsion force that makes the inserting portion 31 of the limiting member 3 move towards the slot 25.

[0073] So that in the state without external force, the limiting member can continuously maintain the restriction on the door panel 23, so that the door panel 23 can fit with the discharge port 12 and continuously ensure the closed state.

[0074] Furthermore, in order to simplify the structure, in this embodiment, there are two groups of limiting members 3, which are symmetrically arranged at both ends of the middle positions of the two door panels 23 respectively, and the inserting portion 31 can be inserted into the slots 25 at the edges of the two door panels 23 on the same side at the same time.

[0075] Such as Figure 4 and Figure 5As shown in the figure, the present utility model provides a specific implementation manner of an automatic feeding device for transferring materials to a silo, including the feeding cylinder, the moving mechanism 4, the clamping mechanism 5, and the force applying mechanism 6 described above.

[0076] Among them, both the clamping mechanism 5 and the force applying mechanism 6 are arranged at the movable end of the moving mechanism 4, so that the clamping mechanism 5 and the force applying mechanism 6 move synchronously.

[0077] The clamping mechanism 5 is used to clamp the cylinder body 1; the moving mechanism 4 is used to move the clamped cylinder body 1 above the silo and make the discharging port of the cylinder body 1 directly above the inlet of the silo or inside the silo; the force applying mechanism 6 is used to apply an external force to the limiting member 3 on the cylinder body 1 to make the limiting member 3 move, so as to release the restriction imposed by the limiting member 3 on the door plate 23; at the same time, the force applying mechanism 6 can also apply an external force to the door plate 23 to open the door plate 23, and the materials inside the cylinder body 1 fall into the silo from the discharging port 12 to complete the discharging.

[0078] In this embodiment, the position of the force applying mechanism 6 is set as follows: in the state where the clamping mechanism 5 clamps the cylinder body 1, the movable end of the force applying mechanism 6 is directly above the stress receiving portion 33 and the edge of the door plate 23.

[0079] In this embodiment, an embodiment of the moving mechanism 4 is provided, as shown in Figure 5 and Figure 6 shown:

[0080] The moving mechanism 4 includes a first lead screw pair 41, a first motor 42, and a mounting seat 43.

[0081] The first lead screw pair 41 is arranged vertically, the first motor 42 is used to drive the screw of the first lead screw pair 41 to rotate, and the mounting seat 43 is arranged vertically on the nut slider of the first lead screw pair 41; the mounting seat 43 is used to arrange the clamping mechanism 5 and the force applying mechanism 6.

[0082] Among them, the first lead screw pair is mainly used to move the cylinder body 1 from directly above the inlet of the silo to inside the silo, so that the cylinder body 1 completes discharging inside the silo; the first lead screw pair 41 can be installed on any carrier to cooperate to complete the action of moving the cylinder body 1 from any position to directly above the inlet of the silo.

[0083] In this embodiment, an embodiment of the clamping mechanism 5 is provided, as shown in Figure 5 and Figure 6 shown:

[0084] The clamping mechanism 5 includes a second lead screw pair 51, a second motor 52 and two groups of clamping jaws 53; the second lead screw pair 51 and the second motor 52 are arranged on the mounting base 43, and the second motor 52 is used to drive the lead screw of the second lead screw pair 51 to rotate; wherein, the second lead screw pair 51 is horizontally arranged, the lead screw of the second lead screw pair 51 is a bidirectional lead screw, and nut sliders are arranged at both ends of the lead screw; the two groups of clamping jaws 53 are symmetrically arranged on the nut sliders of the second lead screw pair 51 respectively.

[0085] Half of the thread part of the bidirectional lead screw has a left-handed thread and the other half has a right-handed thread; when the lead screw rotates in one direction, the two nut sliders on the thread move apart or approach each other at both ends, and when rotating in the opposite direction, the two nut sliders approach or move apart; by the relative movement (approach) of the clamping jaws 53, the wall is clamped, so that the cylinder 1 moves along with the movement of the moving mechanism 4 and the movable end of other carriers.

[0086] In order to make the cylinder 1 relatively fixed with respect to the clamping jaws 53 during the process of clamping the cylinder 1, and ensure that the execution end of the force application mechanism 6 can be located directly above the force receiving part 33 when unloading the cylinder 1, an embodiment of the clamping jaw 53 is provided, as Figure 5 shown:

[0087] The projected shape of the clamping jaw 53 is an L-shaped structure, and the two groups of clamping jaws 53 are horizontally arranged; wherein, the short side part 531 of the clamping jaw 53 is used for connecting with the nut slider of the second lead screw pair 51; positioning blocks 533 are respectively arranged on the opposite side surfaces of the long side parts 532 of the two groups of clamping jaws 53; the distance between the positioning block 533 and the short side part 531 of the clamping jaw 53 is the same as the width of the corresponding position side surface of the cylinder 1; and in the state of clamping the cylinder 1, the short side part 531 of the clamping jaw 53, the long side part 532 of the clamping jaw 53 and the positioning block 533 are all in contact with the side wall of the cylinder 1.

[0088] This structure of the clamping jaw 53 can limit the cylinder 1, so that the position of the cylinder 1 is relatively fixed during the movement process and will not shift in the vertical direction; so that the movable end of the force application member 63 can always be located directly above the force receiving part 33.

[0089] Furthermore, in this embodiment, in order to limit the cylinder 1 from moving horizontally during the movement process, the distance between the positioning block 533 and the short side part 531 of the clamping jaw 53 is the same as the width of the corresponding position side surface of the cylinder 1, which results in that the side surfaces of the clamping jaw 53 and the cylinder 1 cannot be accurately matched during the process of clamping the cylinder 1 by the two groups of clamping jaws 53. To solve this problem, the following structure is provided, as Figure 5 shown:

[0090] The surface of the positioning block 533 facing the short side portion 531 of the clamping jaw 53 is an inclined surface 534; wherein, the distance between one end (outer end) of the inclined surface 534 close to the end face of the positioning block 533 and the short side portion 531 of the clamping jaw 53 is greater than the distance between the other end (inner end) of the inclined surface 534 and the short side portion 531 of the clamping jaw 53.

[0091] That is, the distance between the outer end of the inclined surface 534 and the short side portion 531 of the clamping jaw 53 is greater than the width of the corresponding side surface of the cylinder body 1, and the distance between the inner end of the inclined surface 534 and the short side portion 531 of the clamping jaw 53 is equal to the width of the corresponding side surface of the cylinder body 1; during the process of the clamping jaw 53 clamping the cylinder body 1, the clamping space formed by the outer end of the inclined surface 534 of the positioning block 533 and the short side portion 531 of the clamping jaw 53 can more easily select the side surface of the cylinder body 1.

[0092] As the two clamping jaws 53 move towards each other, the side wall of the cylinder body 1 approaches the long side portion 532 of the clamping jaw 53 until the side wall of the cylinder body 1 fits against the long side portion 532 of the clamping jaw 53 (clamping the cylinder body 1 in the X-axis or Y-axis direction in the horizontal plane direction), and at the same time, the clamping space formed by the inner end of the inclined surface 534 of the positioning block 533 and the short side portion 531 of the clamping jaw 53 clamps the side wall of the cylinder body 1 (clamping the cylinder body 1 in the Y-axis or X-axis direction in the horizontal plane direction).

[0093] Furthermore, in this embodiment, in order to ensure that the movable end of the force applying member 63 can move vertically downward, and during the movement process, the movement direction will not deviate and can accurately apply an external force to the force receiving portion 33, the following structure is provided, as shown in Figure 5 and Figure 6 shown:

[0094] At least one set of guide posts 535 are respectively provided vertically downward at the bottoms of the two groups of clamping jaws 53, and a stop block 536 is provided at the bottom of the guide posts 535; the movable end of the force applying mechanism 6 reciprocates vertically along the guide posts 535.

[0095] Furthermore, in order to further improve the stability of the cylinder body 1 during the movement process, in this embodiment, clamping grooves 14 matching the clamping jaws 53 are respectively provided on both sides of the side wall of the cylinder body 1 with respect to the clamping jaws 53, and the clamping grooves 14 are used to fix the clamping jaws 53 to limit the displacement of the clamping jaws 53 in the vertical direction.

[0096] So that during the process of the clamping mechanism 5 clamping the cylinder body 1, the cylinder body 1 will not slide downward due to the gravity of the cylinder body 1 and the materials inside it.

[0097] In this embodiment, an embodiment of the force applying mechanism 6 is provided, as shown in Figure 5 and Figure 6 shown:

[0098] The force application mechanism 6 includes a third motor 61, a swing rod 62, and a force application member 63; wherein, the force application member 63 is the movable end of the force application mechanism 6.

[0099] The third motor 61 is arranged on the mounting base 43. The third motor 61 drives the swing rod 62 to rotate. Wherein, the rotation plane of the swing rod 62 overlaps or is parallel to the movement plane of the force application member 63; a connecting member 64 is provided at the top of the force application member 63, and a track 65 for the end of the swing rod 62 to slide is provided on the connecting member 64; the swing rod 62 drives the force application member 63 to reciprocate in the vertical direction through its own rotation.

[0100] In this embodiment, the track 65 is a through groove penetrating the connecting member 64. A sliding rod is vertically provided at the end of the swing rod 62, and the sliding rod passes through the through groove so that the sliding rod can slide along the through groove.

[0101] Further, in this embodiment, the force application member 63 includes a base 631 and at least one set of unlocking ejector rods 632. The unlocking ejector rods 632 are vertically arranged downward at the bottom of the base 631; each limiting member 3 corresponds to one set of unlocking ejector rods 632, and the unlocking ejector rods 632 are located directly above the force receiving portion 33; the connecting member 64 is arranged on the top of the base 631, and a guiding hole for sliding along the guiding column 535 is provided on the base 631; a through hole for the unlocking ejector rod 632 to pass through is provided on the stopper 536 in the vertical direction.

[0102] Further, in order to avoid the situation that the gravity of the material in the cylinder 1 is insufficient to open the door panel 23, in this embodiment, the force application member 63 further includes at least two sets of door opening ejector rods 633.

[0103] While the unlocking ejector rod 632 moves downward, the door opening ejector rod 633 also moves downward synchronously, applying a downward pressure to the edge of the door panel 23 to assist in opening the door panel 23 and completing the discharging of materials.

[0104] During the process, there is a sequential order in time for the unlocking ejector rod 632 and the door opening ejector rod 633 to come into contact with the corresponding force application objects; that is, the unlocking ejector rod 632 applies force to the force receiving portion 33 first, and then the door opening ejector rod 633 applies force to the edge of the door panel 23; therefore, the length of the unlocking ejector rod 632 is greater than the length of the door opening ejector rod 633.

[0105] Further, in the case where one of the door panels 23 is provided with a retaining bar 22, in this embodiment, there is also a sequence in time when the door opening ejector rod 633 contacts the corresponding door panel 23; that is, the door opening ejector rod 633 corresponding to the door panel 23 provided with the retaining bar 22 applies force first, and then the door opening ejector rod 633 corresponding to the other door panel 23 applies force; therefore, the length of the door opening ejector rod 633 corresponding to the door panel 23 provided with the retaining bar 22 is greater than the length of the door opening ejector rod 633 corresponding to the other door panel 23.

[0106] In this embodiment, the cylinder body 1 enters the silo from the inlet of the silo and unloads materials inside the silo. In order to prevent the dust generated during unloading from floating out from the inlet of the silo, an embodiment is provided for the cylinder body 1, as Figure 1 and Figure 3 shown:

[0107] A sealing strip 15 that surrounds the bottom of the side wall of the cylinder body 1 is provided, so that when the material discharge port of the cylinder body 1 is inside the silo, the sealing strip 15 can fill the gap between the cylinder body 1 and the inlet of the silo; the dust generated during unloading floats out from the inlet of the silo.

[0108] Further, in this embodiment, in order to optimize the structure, the bracket 13 is arranged to surround the cylinder body 1 in the horizontal position, and the sealing strip 15 is arranged on the side wall of the bracket 13.
