The embodiment of the utility model provides a bean grinder can be used to the grinding operation of coffee beans or other beans, and the present embodiment uses the grinding object to carry out the distance explanation for coffee beans, and bean grinder includes: grind beans knife tackle spare 1 and a plurality of beans storehouse 2, the quantity in beans storehouse 2 can be selected according to the demand, grind beans knife tackle spare 1 and set up in the bottom in beans storehouse 2, the bottom in each beans storehouse 2 all is equipped with the beans screw rod of sending, send the beans screw rod before rotating, place a certain amount of coffee beans in the beans storehouse 2, when the coffee beans in certain beans storehouse 2 of needs grinding, rotate rather than corresponding beans screw rod of sending and can carry to grind beans knife tackle spare 1 in, when the coffee powder of certain ratio needs, the accessible rotates the revolution that sends the beans screw rod and confirms the pay-off volume, send after the beans to end, when sending the beans screw rod stall promptly, grind beans knife tackle spare 1 and should work a period again, in order to ensure that the coffee beans in grinding knife tackle spare 1 are ground completely and empty, so that the next grinding operation. Through the bean grinder that this application provided, through the combination of the beans storehouse 2 of difference and the bean screw rod of sending, not only can carry the grinding to the coffee beans of difference, still can realize the grinding operation of different ratio coffee beans, still possess simple structure in addition, advantage that product low in production cost.

It should be noted that the specific structure and operation principle of the bean grinding knife assembly 1 can refer to the prior art, and are not described herein.

Preferably comprises two bean bins 2, such as a left bean bin 21 and a right bean bin 22 which are arranged at the upper part of the bean grinding knife component 1, the bean feeding screws at the bottoms of the left bean bin 21 and the right bean bin 22 are the same long screw 3, and due to the structural characteristics of the screws, the long screw has the characteristic of one-way conveying, namely when the long screw 3 rotates in one direction, the materials are conveyed towards the advancing direction of the spiral blade, so that when the long screw 3 rotates forwards, only the coffee beans in the right bean bin 22 are conveyed into the bean grinding knife component 1; when the long screw 3 is rotated reversely, only the coffee beans in the left bean magazine 21 are conveyed into the bean grinding cutter unit 1, and it can be understood that when the coffee beans in one of the bean magazines 2 are conveyed, the coffee beans in the other bean magazine 2 do not fall off, and only in the case where the long screw 3 is rotated reversely, the coffee beans in the other bean magazine 2 do not fall off.

Further, a bean feeding motor 4 connected with one end of the long screw rod 3 is further included, the bean feeding motor 4 is used for driving the long screw rod 3 to rotate, the proportion of the beans can be controlled through forward and reverse rotation of the bean feeding screw rod, for example, the proportion of the beans A and the beans B selected by a user is 1:3, the forward rotation and reverse rotation time ratio of the bean feeding motor 4 is 1: and 3, running, wherein the positive and negative rotation can be performed in a mode of positive rotation and then negative rotation, or positive and negative rotation alternatively, and the total positive and negative rotation time ratio is 1: 3. Send beans screw rod level setting in the bottom in beans storehouse 2, send the both ends of beans screw rod to rotate to connect on the lateral wall in beans storehouse 2 promptly, for the convenience of changing beans storehouse 2, can dismantle the beans mouth department of sending of connecting at bean grinding knife tackle spare 1 with beans storehouse 2, wherein preferred can dismantle the beans mouth department of sending of connecting at bean grinding knife tackle spare 1 as a whole subassembly with sending beans screw rod and beans storehouse 2.

Specifically, the bottoms of the left bean bin 21 and the right bean bin 22 are provided with cylinder feeding channels 23, the long screw 3 penetrates through the interior of the cylinder feeding channels 23, wherein the outer edges of the helical blades of the long screw 3 can be contacted with the inner side walls of the cylinder feeding channels 23 to prevent coffee beans from freely falling into the bean grinding cutter assembly 1, the left side and the right side of the upper part of the cylinder feeding channels 23 are respectively provided with a feeding hole 231, and the bottom of the cylinder feeding channels 23 is provided with a discharging hole 232.

Further, the coffee bean grinder comprises a detection device and a control device, wherein the detection device can use a Hall sensor, the detection device is used for detecting the revolution of a bean conveying screw rod, the control device is respectively connected with the detection device and the bean conveying motor 4, and the control device is used for controlling the bean conveying motor 4 to stop rotating when the revolution detected by the detection device meets the preset requirement, namely, the using amount of coffee powder can be accurately controlled by controlling the revolution of the bean conveying motor 4 without being influenced by the fineness of a bean grinding knife adjusted by a user, because the conventional mode of controlling the coffee powder amount is controlled by the working time of the bean grinding motor, but the coffee powder amount can become inaccurate when the fineness of the bean grinding knife is adjustable by the user, when the coarse powder is set, the gap between the upper bean grinding knife and the lower bean grinding knife can become larger, the output amount of the coffee powder at the same time can become larger, but after the beans are conveyed by the bean conveying screw rod, the amount of beans is determined by the number of revolutions of the screw rather than being affected by the bean grinding cutter unit 1.

It is worth mentioning that, this application can use a screw rod just to rotate forward and backward and a send beans motor just can control two beans storehouses to do the use of independently sending beans, of course, can think in the field of technical staff in the field of can also realize the independent beans operation of sending beans in two beans storehouses separately to two independent screw rods and two send beans motors, also be in the protection scope of the utility model, the technical staff in the field of can also think in the technical scheme shown in figure 1 to increase a set of coffee beans storehouse and coffee beans conveyer, just can realize a knife sharpening component and cooperate four beans storehouses, namely the user can do four kinds of different coffee taste and select, can so analogize to 6 kinds of, 8 kinds of coffee taste's scheme, in addition if realize 3 coffee taste's scheme, on the basis of figure 1, increase a beans storehouse and independent screw rod and send beans motor.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The bean grinder provided by the utility model is introduced in detail.
