DETAILED DESCRIPTION

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0026] like Figure 1 , Figure 2As shown, an automatic feeding machine for building blocks includes a silo 1, a partition mechanism 2 and an auger conveyor 3. The upper end of the silo 1 is set to be an opening, and the lower end is set to be a frustum structure. A control valve is set at the discharge hole of the frustum structure. The partition mechanism 2 is set in the middle of the silo 1, and can adjust its own state according to needs, and separate the silo 1 to form two upper and lower spaces. The upper space is a mixing space, and the lower space is a temporary storage space. A mixing shaft 11 is set in the mixing space, and a plurality of mixing blades are set on the mixing shaft 11. The auger conveyor 3 is set on the side of the silo 1 and is inclined. The lower end of the auger conveyor 3 is connected to the lower end of the silo 1, and the upper end can extend to the top of the molding machine. When the feeding device is used in conjunction with the molding machine to complete the production of blocks, a variety of raw materials can be put into the mixing space according to scientific proportions, and the various raw materials can be fully mixed by the rotation of the mixing shaft 11. After the various raw materials are fully mixed, the partition mechanism 2 is controlled to work and change its own state so that the mixing space and the temporary storage space are connected, and the materials fall from the mixing space into the temporary storage space. When the materials are completely output from the mixing space and the partition mechanism 2 isolates the mixing space and the temporary storage space, various materials can continue to be added to the mixing space to complete the full mixing of the various materials. This setting changes the current situation in which the existing mixing bin takes a long time to slowly output the materials after fully mixing the materials, which affects the efficiency of block material transportation. It also changes the current situation in which the materials output from the mixing bin still need to be transferred to the molding machine feeding device by the staff using a transfer vehicle, and correspondingly improves the efficiency of material transportation. The materials in the temporary storage space can be output from the storage hole and transported to the molding machine through the auger conveyor 3, changing the two ways of completing material transportation through the cooperation of the auger conveyor 3 and the bucket elevator, thereby reducing the cost of the feeding device.

[0027] like Figure 4 As shown, in order to control the falling of materials through the operation of the partition mechanism 2, the partition mechanism 2 includes a bidirectional screw 21 and two symmetrically arranged partition plates 22, the width of the partition plate 22 is greater than the radius of the silo 1, and the length is greater than the diameter of the silo 1, and convex plates 23 are provided at the adjacent ends of the two partition plates 22 below, and the two convex plates 23 are respectively threadedly sleeved on the two ends of the bidirectional screw 21, and the bidirectional screw 21 is connected to the motor. The rotation of the bidirectional screw 21 can be controlled by the operation of the motor, and then the two partition plates 22 can be controlled to be relatively close or far away, and the maximum relative distance can be equal to the diameter of the silo 1. In this case, the connecting channel between the mixing space and the temporary storage space is expanded to the greatest extent, the falling of the material is accelerated, and convenience is provided for quickly outputting the material from the mixing space.

[0028] like Figure 1 , Figure 3As shown, in order to stably install the partition mechanism 2 on the silo 1 and facilitate its operation, an extension plate 13 is horizontally arranged in the middle of the silo 1. The extension plate 13 is arranged in a rectangular structure, and the length and width are both greater than the diameter of the silo 1. Perforations 14 are arranged on the two opposite end faces of the extension plate 13. The length of the perforations 14 is greater than the diameter of the silo 1 and communicates with the internal space of the silo 1. The arrangement of the extension plate 13 can enhance the strength of the silo 1 at this location and provide support for the stable installation and operation of the partition mechanism 2. Two partition plates 22 are respectively arranged through the two perforations 14, and the ends extend into the side wall of the silo 1. Therefore, the partition plates 22 can be arranged stably and flexibly relative to the silo 1 and carry materials of corresponding mass. The ends of the bidirectional screw 21 protrude from the silo 1.

[0029] like Figure 3 As shown, in order to further enhance the strength of the silo, a reinforcing plate 12 is provided at the upper end of the silo 1 , and at the same time, sufficient space is provided for the installation of the auger conveyor 3 , and a support leg 15 is provided at the lower end of the silo 1 . Example 2

[0030] like Figure 1 , Figure 2 As shown, an automatic feeding machine for building blocks includes a silo 1, a partition mechanism 2 and an auger conveyor 3. The upper end of the silo 1 is set to be an opening, and the lower end is set to be a frustum structure. A control valve is set at the discharge hole of the frustum structure. The partition mechanism 2 is set in the middle of the silo 1, and can adjust its own state according to needs, and separate the silo 1 to form two upper and lower spaces. The upper space is a mixing space, and the lower space is a temporary storage space. A mixing shaft 11 is set in the mixing space, and a plurality of mixing blades are set on the mixing shaft 11. The auger conveyor 3 is set on the side of the silo 1 and is inclined. The lower end of the auger conveyor 3 is connected to the lower end of the silo 1, and the upper end can extend to the top of the molding machine. When the feeding device is used in conjunction with the molding machine to complete the production of blocks, a variety of raw materials can be put into the mixing space according to scientific proportions, and the various raw materials can be fully mixed by the rotation of the mixing shaft 11. After the various raw materials are fully mixed, the partition mechanism 2 is controlled to work and change its own state so that the mixing space and the temporary storage space are connected, and the materials fall from the mixing space into the temporary storage space. When the materials are completely output from the mixing space and the partition mechanism 2 isolates the mixing space and the temporary storage space, various materials can continue to be added to the mixing space to complete the full mixing of the various materials. This setting changes the current situation in which the existing mixing bin takes a long time to slowly output the materials after fully mixing the materials, which affects the efficiency of block material transportation. It also changes the current situation in which the materials output from the mixing bin still need to be transferred to the molding machine feeding device by the staff using a transfer vehicle, and correspondingly improves the efficiency of material transportation. The materials in the temporary storage space can be output from the storage hole and transported to the molding machine through the auger conveyor 3, changing the two ways of completing material transportation through the cooperation of the auger conveyor 3 and the bucket elevator, thereby reducing the cost of the feeding device.

[0031] like Figure 4 As shown, in order to control the falling of materials through the operation of the partition mechanism 2, the partition mechanism 2 includes a bidirectional screw 21 and two symmetrically arranged partition plates 22, the width of the partition plate 22 is greater than the radius of the silo 1, and the length is greater than the diameter of the silo 1, and convex plates 23 are provided at the adjacent ends of the two partition plates 22 below, and the two convex plates 23 are respectively threadedly sleeved on the two ends of the bidirectional screw 21, and the bidirectional screw 21 is connected to the motor. The rotation of the bidirectional screw 21 can be controlled by the operation of the motor, and then the two partition plates 22 can be controlled to be relatively close or far away, and the maximum relative distance can be equal to the diameter of the silo 1. In this case, the connecting channel between the mixing space and the temporary storage space is expanded to the greatest extent, the falling of the material is accelerated, and convenience is provided for quickly outputting the material from the mixing space.

[0032] like Figure 1 , Figure 3 As shown, in order to stably install the partition mechanism 2 on the silo 1 and facilitate its operation, an extension plate 13 is horizontally arranged in the middle of the silo 1. The extension plate 13 is arranged in a rectangular structure, and the length and width are both greater than the diameter of the silo 1. Perforations 14 are arranged on the two opposite end faces of the extension plate 13. The length of the perforations 14 is greater than the diameter of the silo 1 and communicates with the internal space of the silo 1. The arrangement of the extension plate 13 can enhance the strength of the silo 1 at this location and provide support for the stable installation and operation of the partition mechanism 2. Two partition plates 22 are respectively arranged through the two perforations 14, and the ends extend into the side wall of the silo 1. Therefore, the partition plates 22 can be arranged stably and flexibly relative to the silo 1 and carry materials of corresponding mass. The ends of the bidirectional screw 21 protrude from the silo 1.

[0033] like Figure 3 As shown, in order to further enhance the strength of the silo, a reinforcing plate 12 is provided at the upper end of the silo 1 , and at the same time, sufficient space is provided for the installation of the auger conveyor 3 , and a support leg 15 is provided at the lower end of the silo 1 .

[0034] like Figure 1 , Figure 5 As shown, in order to limit the moving direction of the material output from the upper end of the auger conveyor 3, a guide mechanism 4 is provided at the upper end of the auger conveyor 3, and the guide mechanism 4 can be located above the molding machine.

[0035] like Figure 5As shown, the guide mechanism 4 includes a feed pipe 41, a bellows 42 and a connecting pipe 43. The connecting pipe 43 and the feed pipe 41 are respectively connected and arranged at the two ends of the bellows 42. The end of the connecting pipe 43 is fixedly sleeved with a sleeve 44. The lower end of the sleeve 44 is sleeved on the auger conveyor 3 through a bearing connection, and a bolt is threaded through. The end of the bolt presses the auger conveyor 3. A telescopic cylinder 45 is obliquely arranged between the feed pipe 41 and the connecting pipe 43. Since the sleeve 44 is movably sleeved on the auger conveyor 3, the direction of the feed pipe 41 can be adjusted according to actual needs to facilitate the conveying of materials into the molding machine. After adjusting the direction of the feed pipe 41, the bolt can be rotated to make its end press the auger conveyor 3 to control the feed pipe 41 to be stably placed relative to the auger conveyor 3. Of course, the direction of the feed pipe 41 can also be adjusted by working with the telescopic cylinder 45 (which can be set as an electric cylinder), which increases the practicality and flexibility of the device.

[0036] like Figure 6 As shown, an auger conveyor 3 may also be provided on the side of the silo 1, but the upper end of the auger conveyor 3 is located above the silo 1 so as to convey the raw materials into the mixing space for mixing.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
