DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Embodiment 1:

[0024] See also Figure 1-3 A feeding device for dry-mix mortar production includes a mixing tank 1, a supporting leg 11 is provided at the bottom of the mixing tank 1, a feeding port 12 is provided at the top of the mixing tank 1, and a plurality of weighing components 2 are slidably connected in the feeding port 12; the weighing components 2 are provided so that the raw materials can be effectively weighed during the feeding process, and the need to weigh the dry-mix mortar in advance when mixing it is effectively avoided, thereby reducing the workload of the staff and increasing their work efficiency.

[0025] The bottom of the mixing tank 1 is provided with a connecting block 31, a supporting platform 34, a mounting seat 36 and a discharge port 13, and the discharge port 13 is provided with a solenoid valve 14; by providing the solenoid valve 14 on the discharge port 13, it is convenient for the staff to control the discharge effect.

[0026] In order to prevent raw materials from sticking to the inside of the discharge port 13 during the discharging process, a rotating motor 37 is arranged in the mounting seat 36 in this embodiment, and the output shaft of the rotating motor 37 is fixedly connected to a transmission cam 38. A connecting arm 32 is rotatably connected to the connecting block 31, and a hammer 33 is arranged at the lower end of the connecting arm 32. A return spring 35 is arranged on the support platform 34, and the other end of the return spring 35 is fixedly connected to the connecting arm 32.

[0027] As a preferred technical solution in this embodiment, when the staff needs to control the discharge port 13 to collect the raw materials after mixing, the rotating motor 37 can be controlled to drive the transmission cam 38 to rotate. When the protruding part of the transmission cam 38 contacts the connecting arm 32 during the rotation of the transmission cam 38, the connecting arm 32 will be displaced. During the displacement of the connecting arm 32, the hammer 33 can be driven to displace, so that the hammer 33 hits the discharge port 13. The discharge port 13 will vibrate after being hit. During the vibration, the dry powder mortar attached to its inner wall can fall off. At the same time, during the displacement of the connecting arm 32, the reset spring 35 can be compressed. When the protruding part of the transmission cam 38 leaves the connecting arm 32, the reset spring 35 can rebound to achieve the resetting effect of the connecting arm 32. When the protruding part of the transmission cam 38 contacts the connecting arm 32 again, the impact effect on the discharge port 13 can be achieved again. This connection method can not only prevent the dry mortar from adhering to the discharge port 13 during use, but also speed up the discharge speed of the discharge port 13, thereby effectively ensuring its use effect.

[0028] In order to prevent the discharge port 13 from being deformed by the impact of the hammer 33, a protective ring 15 is provided on the discharge port 13 in this embodiment. The protective ring 15 is made of rubber. The protective ring 15 can not only provide a good protection effect on the discharge port 13, but also effectively prevent the generation of noise during use.

[0029] Embodiment 2:

[0030] See also Figure 4-5 In order to weigh the raw materials in advance during the feeding process, the weighing assembly 2 in this embodiment is provided with a hopper 21, and a guide block 23 is provided on the hopper 21. The hopper 21 is slidably connected to the feeding port 12, and the guide block 23 is used to guide the hopper 21. The guide block 23 is provided to effectively ensure the stability of the hopper 21 when sliding in the feeding port 12 during use, thereby ensuring its use effect. A connecting rod 22 is provided on the hopper 21, and a weight sensor 24 is provided on the connecting rod 22. A support rod 25 is provided at the bottom of the weight sensor 24, and the support rod 25 is fixedly connected to the top of the mixing tank 1. This connection method can effectively ensure that it can achieve the weighing effect on the raw materials in the hopper 21. During actual use, the staff can set the weight sensor 24 to different sensing parameters according to the weight required to be added to different raw materials, and connect the weight sensor 24 to the transmission motor 28 with wires to ensure that the weight sensor 24 can achieve the control effect on the transmission motor 28, that is, when the weight sensed by the weight sensor 24 reaches its set parameters, the transmission motor 28 can be controlled to start.

[0031] A protective cover 27 is provided in the hopper 21, a transmission motor 28 is provided in the protective cover 27, a transmission arm 29 is fixedly connected to the output shaft of the transmission motor 28, and a baffle 26 is fixedly connected to the other end of the transmission arm 29. This connection mode can drive the transmission arm 29 to produce a rotation effect when the transmission motor 28 is started, and the baffle 26 can be opened during the rotation of the transmission arm 29, so that the raw materials in the hopper 21 enter the mixing tank 1 to achieve the mixing effect.

[0032] The working principle of the above embodiment is:

[0033] 1. When the staff controls the solenoid valve 14 to discharge the material from the discharge port 13, in order to avoid the adhesion of dry mortar inside the discharge port 13, the rotating motor 37 can be controlled to drive the transmission cam 38 to rotate. When the protruding part of the transmission cam 38 contacts the connecting arm 32 during the rotation of the transmission cam 38, the connecting arm 32 will be displaced. During the displacement of the connecting arm 32, the hammer 33 can be displaced, so that the hammer 33 hits the discharge port 13. The discharge port 13 will vibrate after being hit. During the vibration, the dry mortar attached to the inner wall can fall off. At the same time, during the displacement of the connecting arm 32, the reset spring 35 can be compressed. When the protruding part of the transmission cam 38 leaves the connecting arm 32, the reset spring 35 can rebound to achieve the reset effect of the connecting arm 32. When the protruding part of the transmission cam 38 contacts the connecting arm 32 again, the impact effect on the discharge port 13 is achieved again. This connection method can not only prevent the dry mortar from adhering to the discharge port 13 during use, but also speed up the discharge speed of the discharge port 13, thereby effectively ensuring its use effect.

[0034] 2. When adding raw materials, the staff can first set the weight sensor 24 to different sensing parameters according to the weight of different raw materials to be added, and connect the weight sensor 24 to the transmission motor 28 with wires to ensure that the weight sensor 24 can achieve the control effect of the transmission motor 28. When the weight sensed by the weight sensor 24 reaches its set parameters, the transmission motor 28 can be controlled to start. When the transmission motor 28 starts, it can drive the transmission arm 29 to produce a rotation effect. During the rotation of the transmission arm 29, the baffle 26 can be opened, so that the raw materials in the hopper 21 enter the mixing tank 1 to achieve the mixing effect.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
