[0002] Different requirements for sand making have different requirements for the size of the feed port of the sand making machine. For example, when the demand for sand making is large, the size of the feed port needs to be increased, and when the demand for sand making is small, the size of the feed port needs to be decreased. However, the size of the feed port of most current sand making machines is fixed and cannot be adjusted, which will affect the efficiency of sand making and may also lead to waste of materials.

[0012] In one of the specific embodiments, the support frame is frame-shaped and connected to the side wall of the material inflow bin through front and rear symmetrical extension ends. A rotating shaft passes through the two extension ends and is connected to the hydraulic push rod.

[0013] In one specific embodiment, the spacing between the two side plates is equal to the width of the material guide port, which is combined with the flap and the docking plate to form a material cutting unit, and the amount of sand and gravel passed by the material cutting unit is based on the rotation angle of the flap.

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] In view of the different sand making needs in the prior art, there are different requirements for the size of the feed opening of the sand making machine. For example, when the sand making demand is large, the size of the feed opening needs to be increased, and when the sand making demand is small, the size of the feed opening needs to be decreased. However, the size of the feed opening of the current sand making machine is mostly fixed and non-adjustable, which will affect the efficiency of sand making and may also cause waste of materials. This embodiment specifically solves the above problem through a feed controllable adjustment device.

[0027] First embodiment

[0028] like Figure 1-Figure 2 As shown, it is provided with a material inflow bin 1 installed on the feeding port 2 of the sand making machine. The material inflow bin 1 is installed at one end of the feeding port 2 for storing sand and gravel to be processed. A guide port 3 for providing overflow of sand and gravel to the feeding port 2 is opened on the side wall of the material inflow bin 1 opposite to the feeding port 2. The material guide port 3 establishes or releases the connection state with the feeding port 2 by installing a limiting device 4. The speed and total amount of material flowing into the feeding port 2 through the guide port 3 are controlled by controlling the closing or opening of the limiting device 4 and the degree of opening, thereby meeting different sand making needs.

[0029] The material limiting device 4 includes a side plate 41 symmetrically installed on the side wall of the material inflow bin 1 for forming a material limiting channel, a flap 42 is installed at the opening position of the material guide port 3 in the material limiting channel, and a docking plate 43 is arranged under the flap 42 to cooperate with it to block the overflow of sand and gravel and extend toward the feed port 2. The docking plate 43 is a straight plate, and the bottom surface of the flap 42 is an inclined surface for fitting with the docking plate 43. The flap 42 is rotatably connected to the free end of the hydraulic push rod 44, and the width of the flap 42 is adapted to the opening width of the material guide port 3. The bottom surface of the flap 42 is connected to the top surface of the docking plate 43. Covering the material guide port 3, the spacing value of the two side plates 41 is equal to the width value of the material guide port 3, which is used to be combined with the flap 42 and the docking plate 43 to form a material cutting unit, and the amount of sand and gravel passed by the material cutting unit is based on the rotation angle of the flap 42, and the rotation driving force of the flap 42 angle is derived from the hydraulic push rod 44 connected to the flap 42 and penetrating the side plate 41. The hydraulic push rod 44 is rotatably connected to the support frame 45 and the movable range of the free end of the hydraulic push rod 44 is always located in the material limiting channel. The extension and retraction of the hydraulic push rod 44 is adjusted by the frequency converter to control the opening angle of the flap 42. When the feed amount is appropriate, the opening angle of the flap 42 remains constant, the feed is even, and the feed is kept controllable. The hydraulic push rod 44 is arranged on the support frame 45 at the upper end of the sand making machine. The support frame 45 is U-shaped and connected to the side wall of the material inflow bin 1 through front and rear symmetrical extension ends. A rotating shaft 46 passes through the two extension ends and is connected to the hydraulic push rod 44. In specific production, the rotating shaft 46 can be coaxially connected to the drive motor to facilitate the hydraulic push rod 44 to adapt to the rotation of the flap 42 and maintain the pushing angle thereof. Therefore, the drive motor can be controlled to start under the action of the controller to drive the hydraulic push rod 44 to rotate on the support frame 45.

[0030] Second embodiment

[0031] like Figure 3 , Figure 4 As shown, based on the first embodiment, this embodiment is based on the consideration that small particles of sand and gravel in the sand and gravel material are easy to adhere to the docking plate 43. Different from the first embodiment, a plurality of inner grooves 47 opened at equal distances are arranged on the docking plate 43, and a material removal column 48 is installed on the bottom surface of the flap 42 to clean the sand and gravel particles retained on the docking plate 43. The opening depth of the inner groove 47 is adapted to the diameter value of the material removal column 48. The material removal column 48 is made of a flexible material and can be deformed when squeezed by the groove wall of the inner groove 47, so as to be tightly combined with the groove wall of the inner groove 47 to form a pushing surface for the sand and gravel. The end thereof facing away from the hydraulic push rod 44 is arranged as an inclined surface so as to facilitate contact with the inner groove 47 before the flap 42, and push the sand and gravel in the inner groove 47, so that it follows the material removal column 48 to move toward the guide port 3. On the one hand, the inner groove 47 can be cleaned, and on the other hand, it can avoid the existence of sand and gravel on the docking plate 43, which causes the flap 42 and the docking plate 43 to be not tightly fitted and cause leakage.

[0032] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0033] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] 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.
