Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean grinders, in particular to a rotary hatch of a coffee bean grinder bean bin. Background Art

[0002] A grinder is a device used to grind coffee beans into powder, usually operated by electric or manual. It is one of the essential tools for coffee lovers and professional baristas, as it can provide one of the key steps in making excellent coffee. The design of a grinder usually includes a bean hopper to hold the coffee beans, a blade or a grinding disc to grind the coffee beans, and a setting to adjust the degree of grinding. The working principle of this machine is to put the coffee beans into the container, and then grind them into powders of different particle sizes by rotating the blade or grinding disc, from fine powder to coarse powder, to suit different coffee making methods.

[0003] The bean hopper of a traditional coffee grinder cannot flexibly control the flow of beans into the grinding hopper when the beans are dropped, so that a large amount of beans enters the grinding disc when the hopper door is opened, causing blockage and accumulation of beans, thereby reducing the grinding efficiency and increasing the risk of parts damage. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the bean bin of the traditional coffee bean grinder cannot flexibly control the flow rate of beans entering the bean grinding bin when the beans are dropped, so that a large amount of beans enter the grinding disc when the bean bin door is opened, causing blockage and accumulation of beans, thereby reducing the grinding efficiency and increasing the risk of parts damage.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: provides a rotating hatch of a bean bin of a bean grinder, including a bean bin, a mounting plate is provided below the bean bin, a mounting groove is provided on the mounting plate, a through hole is provided in the middle position of the mounting groove, a plurality of slide grooves are provided at equal angles around the through hole on the upper surface of the mounting groove, a rotating plate is provided between the bean bin and the mounting plate, the rotating plate is installed at the bottom of the bean bin, a bean dropping hole is provided in the middle position of the rotating plate, a plurality of long strip-shaped through openings are provided at equal angles around the bean dropping hole on the rotating plate, the rotating plate is clamped in the mounting groove, an opening and closing door is provided between the mounting groove and the rotating plate, the opening and closing door is composed of a plurality of fan-shaped rotating plates, each of the rotating plates is provided with two insertion holes, and a shaft rod is inserted in the insertion hole.

[0006] Furthermore, the through hole and the bean-dropping hole are concentric circular holes, and the diameter of the through hole is larger than the diameter of the bean-dropping hole.

[0007] Furthermore, five sliding grooves are opened at equal angles on the installation groove; five through-holes are opened at equal angles on the rotating plate, and each through-hole is located above each sliding groove; the opening and closing door is composed of five rotating plates of the same fan shape.

[0008] Furthermore, the socket is divided into a first socket and a second socket; the shaft is divided into a first shaft inserted in the first socket and a second shaft inserted in the second socket, and the second shaft passes through the through hole and is slidably inserted in the slide groove.

[0009] Furthermore, the rotating piece is circular and has four latches at equal angles on its edge.

[0010] Furthermore, the installation disk is provided with recessed grooves of the same position, quantity and size as the key, and the side wall of the installation groove is provided with a slot for clamping the rotating piece, and the rotating piece can rotate in the slot.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By fixing the rotating piece to the bottom surface of the bean bin, the bean bin rotates and drives the opening and closing door composed of five fan-shaped rotating pieces between the rotating piece and the mounting plate to open and close back and forth while rotating, so that the beans can go down into the bean grinding bin for grinding. The amount of beans fed can be flexibly controlled according to the rotation angle of the bean bin, ensuring the stability and controllability of the downward flow of beans from the bean bin, thereby avoiding the overflow or confusion of excess beans, reducing the possibility of bean blockage or accumulation, and increasing the working efficiency of the grinder.

[0013] 2. The opening and closing door is composed of multiple fan-shaped rotating pieces, each of which has two sockets and is connected by a plug-in shaft. This design ensures the stability and reliability of the door and effectively prevents the door from loosening or falling off during operation.

[0014] 3. The rotating piece is circular and has four keys on the edge, which match the sink and slots on the mounting plate. This design allows the rotating piece to remain stable during use, while facilitating the replacement and maintenance of the rotating piece, extending the service life and maintenance cycle of the grinder.
