DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] A feed transfer device for a cement mixing station, such as Figure 1 , 23, it comprises a bracket 1, on which a hopper 2 is fixedly mounted, the hopper 2 is a trapezoidal box structure, which is wide at the top and narrow at the bottom, with a wide feed inlet at the top and a discharge port smaller than the feed inlet at the bottom, two gates 3 with adjustable openings are movably mounted at the bottom of the hopper 2, the front and rear side walls of the lower part of the hopper 2 are arc-shaped, the upper side of the gate 3 is in sliding contact with the lower side of the hopper 2, and the two gates 3 can move synchronously in opposite directions, and a control mechanism capable of controlling the opening and closing of the gate 3 is provided on the bracket 1, characterized in that: levers 7 are rotatably mounted on the edges of the inner wall of the hopper 2, and rotating shafts are fixedly mounted on the levers 7, corresponding The rotating shafts are rotatably mounted on the side walls of the hopper 2 through bearings, the lever 7 is rotatably connected to the special-shaped gear 4 through a one-way bearing, the outer periphery of the special-shaped gear 4 has only one tooth block, the rotating shafts of the special-shaped gear 4 and the lever 7 are coaxially arranged, the special-shaped gear 4 and the rotating shafts of the lever 7 are rotatably connected through a one-way bearing, one side of the special-shaped gear 4 is matched with a first gear 5, the tooth block of the special-shaped gear 4 is in contact with the first gear 5, the gate 3 is fixedly mounted with an arc rack 6, the front and rear sides of the inner wall of the gate 3 are respectively fixedly mounted with the arc rack 6, the arc rack 6 can mesh with the first gear 5, and the moving track of the arc rack 6 is tangent to the outer periphery of the first gear 5. The utility model has a simple structure and an ingenious design. By controlling the opening angle of the gate 3, the lever 7 is controlled to clean the cement or aggregate accumulated at the edge of the hopper 2, so that the cement or aggregate in the hopper 2 is discharged more cleanly, which can meet actual needs and is suitable for promotion. When using the utility model, firstly, the gate 3 is controlled to be closed by the control mechanism, and then cement or aggregate is put into the gathering hopper 2 through the opening on the upper side of the gathering hopper 2. Then, when feeding is needed, the two gates 3 are controlled to rotate outwards by the control mechanism, so that the arc-shaped rack 6 on the gate 3 is in a state that it has not yet meshed with the first gear 5. At this time, the cement or aggregate in the gathering hopper 2 falls into the cement mixing station from the opening on the lower side of the gathering hopper 2. When the cement or aggregate stops falling, the two gates 3 are controlled by the control device to continue to rotate outwards. At this time, the arc-shaped rack 6 meshes with the first gear 5 and drives the first gear 5 to rotate. The rotation of the first gear 5 drives The tooth block on the movable special-shaped gear 4 rotates, and under the action of inertia, the outer end of the lever 7 is lifted upward, and when the tooth block of the special-shaped gear 4 rotates to no longer contact with the first gear 5, under the action of the gravity of the lever 7 itself, the outer end of the lever 7 falls down and drives the tooth block to contact and cooperate with the first gear 5 again. Therefore, in the process of the arc-shaped rack 6 meshing with the first gear 5 and driving the first gear 5 to rotate, the lever 7 swings up and down quickly to shake off the cement or aggregate stuck in the edge of the hopper 2; in the process of closing the gate 3, under the action of the one-way bearing, the first gear 5 cannot drive the lever 7 to rotate, thereby avoiding interference between the lever 7 and the inner wall of the hopper 2.
[0017] Specifically, as shown in the figure, the control mechanism of this embodiment includes a pull rod 20, the lower end of which is hingedly mounted on the bracket 1, the upper end of which is bent outward, and one end of the connecting rod 21 is hingedly connected to the pull rod 20, and the other end of the connecting rod 21 is hingedly mounted on the gate 3. When the pull rod 20 is pulled, the pull rod 20 rotates outward along the hinge axis with the bracket 1, thereby driving the connecting rod 21 and the corresponding gate 3 to move outward, and the opening angle of the gate 3 can be controlled by changing the rotation angle of the pull rod 20.
[0018] Further, as shown in the figure, the gates 3 of this embodiment are rotatably mounted on the side walls of the hopper 2, and the coaxial second gears 30 are fixedly mounted on the rotating shafts of the gates 3, and the two second gears 30 are meshed with each other. When one gate 3 rotates, it drives the corresponding second gear 30 to rotate, and then drives the other second gear 30 meshed with it to rotate, so that the other gate 3 rotates in the opposite direction.
[0019] Furthermore, as shown in the figure, several spiral blades 40 are rotatably mounted on the hopper 2 of the present embodiment, and the upper end of the rotating shaft of the spiral blade 40 is rotatably mounted on the hopper 2 through a sleeve, and several support rods are fixedly mounted on the outer periphery of the sleeve, and the outer ends of the support rods are fixedly connected to the corresponding side walls of the hopper 2, respectively. The hopper 2 is provided with a driving device for driving the several spiral blades 40 to rotate synchronously. Cement may clump during storage, especially in high humidity or long storage time, causing cement powder to be stuck in the hopper 2 and unable to fall off by itself. The driving device drives the several spiral blades 40 to rotate, so that the several spiral blades 40 can break up the surrounding cement powder to facilitate the landing of the cement powder.
[0020] Furthermore, as shown in the figure, the driving device described in this embodiment includes a motor 50, which is fixedly mounted on the hopper 2. The front and rear sides of the hopper 2 are respectively provided with reserved holes, and the rotating shaft 51 is rotatably mounted in the reserved holes. The two ends of the rotating shaft 51 are rotatably mounted in the corresponding reserved holes through bearings. The output shaft of the motor 50 is fixedly connected to one end of the rotating shaft 51, and a plurality of first bevel gears 52 are fixedly mounted on the outer periphery of the rotating shaft 51. A second bevel gear 53 is respectively meshed and matched on one side of the first bevel gear 52, and the second bevel gears 53 are respectively coaxially fixedly mounted on the rotating shaft corresponding to the spiral blade 40. When the motor 50 is started, the output shaft of the motor 50 rotates to drive the rotating shaft 51 and the plurality of first bevel gears 52 to rotate, and the first bevel gear 52 drives the corresponding plurality of second bevel gears 53 to rotate, thereby driving the spiral blade 40 to rotate.
[0021] Furthermore, as shown in the figure, the outer periphery of the upper end of the pull rod 20 in this embodiment is provided with an anti-skid pad 60. The anti-skid pad 60 can increase the comfort when the pull rod 20 is pulled by hand.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
