Referring to fig. 3, 4 and 5, the grain-placing cylinder 130 has a bottom surface 131 and a cylinder wall 132 arranged around the periphery of the bottom surface, the bottom surface 131 is inclined at an angle α to the horizontal plane, 10 ° or more and 85 ° or less, so as to form a high part and a low part, and the high part is higher than the outlet 11. Preferably, in order to facilitate the falling of the grains, the grain outlet passage 400 is preferably arranged to be inclined with respect to the horizontal plane. One end of the grain outlet channel 400 is connected with the bottom surface 131 or the cylinder wall 132 or the joint of the two at the high part, and the other end is connected with the outlet 11.

Referring to fig. 2, 3, 6 and 7, the lower portion of the grain storage chamber 100 extends obliquely from one side to the opposite side to form an oblique and straight slope 120, and the oblique and straight slope 120 is parallel to the bottom surface 131 and partially covers the bottom surface. The opposite side surfaces are gradually inclined and collected to form a feeding gentle slope 110, and the inclined straight slope 120 is located above the feeding gentle slope 110.

The inclined straight slope 120 is arranged on one side of the grain storage chamber 100, and the bottom surface 131 of the grain discharge cylinder 130 is inclined, so that the volume of the inner cavity of the grain storage chamber 100 is enlarged as much as possible, and more grains can be stored.

Referring to fig. 2, 3, 8 and 9, a rotatable distributing tray 140 is arranged in the grain discharging barrel 130, and is arranged at the same angle with the bottom surface 131, one part of the rotatable distributing tray is opposite to the opposite grain discharging opening 103, and the other part of the rotatable distributing tray is positioned between the inclined straight slope 120 and the barrel bottom surface 131. After falling into the grain discharging barrel 130, the grains firstly fall into the distributing tray 140 which is opposite to the grain discharging opening 130. The distribution plate 140 rotates, and the grain rotates to a position between the inclined straight slope 120 and the bottom surface 131. When the grain discharging channel 400 is rotated, the grain falls into the grain discharging channel 400, and the grain discharging is realized through the outlet 11.

The dispensing disc 140 has a central shaft cylinder 141, and the central shaft cylinder 141 is perpendicular to the bottom surface 131.

The central shaft cylinder 141 is provided with a cylindrical main body part 145, the side wall of the main body part 145 is uniformly provided with a plurality of spacers 146, the peripheral area of the main body part is divided into a plurality of independent spaces, and food falls into the material distribution chamber and then is distributed between two adjacent spacers 146.

Referring to fig. 2 and 8, in order to prevent too much grain from falling into the grain discharging barrel 130 and from being stuck, an anti-sticking comb 150 is provided at the bottom of the inclined straight slope 120. The anti-seizing comb 150 has a comb back 151 and comb teeth 152 provided on the comb back, the free ends of the comb teeth 152 facing and being close to the spacer 146; when the distribution disc 140 rotates, the comb teeth 152 prevent grains scattered on the spacers 146 from passing through, and the grains between the spacers 146 are leveled, so that the grain discharging amount is controlled, grain blockage is prevented, and quantitative feeding is realized.

The middle of the comb back 151 is an arc-shaped portion 153, two sides of the arc-shaped portion 153 extend to form straight portions 154, and the straight portions 154 extend downward to form the comb teeth 152. The flat portion 154 has a triangular cross-section, and the comb teeth 152 are linearly arranged on the flat portion 154, and the angle between the comb teeth 152 and the flat portion 154 is preferably 90-135 °.

The second latch 111 may be disposed on the straight portion 154, and the second engaging groove 155 may be disposed on the inclined straight slope 120.

The arc-shaped portion 153 of the anti-seizing comb 150 is erected above the central bobbin 141 around the top of the central bobbin 141, thereby distributing the comb teeth 152 on both sides of the main body portion 145. Preferably, the comb teeth 152 are located above the spacer 146 at a vertical distance of 3-10mm from the spacer 146, thereby preventing the comb teeth 152 from impeding the spacer rotation.

Grain is accumulated in the grain discharging cylinder 130 and is scattered between the spacers 146. When there is more grain, the grain is accumulated to a height exceeding the spacer 146. When the distribution disc 140 rotates, the spacer 146 pushes the grains to rotate towards the grain outlet channel 400. The anti-jamming comb 150 prevents the grains higher than the spacer 146 from passing through, and smoothes the grains, thereby controlling the amount of the released grains. When the grain rotates to the grain outlet channel 400, the grain falls to the outlet 11 through the grain outlet channel 400. This structure realizes the control to the volume of putting out cereal, prevents too much grain card in putting out the grain passageway, realizes the effect of anti-sticking grain.

The button assembly 50 has a general structure, such as a snap structure, a lock structure, etc., which are well known to those skilled in the art, and the present invention is not repeated herein.

Preferably, a residual grain detection element 104 is arranged on the grain storage chamber 100, and a double-color indicator lamp 108 is arranged on the shell; the residual grain detecting element 104 is electrically connected with the double-color indicator lamp 108, and the detection result is displayed through the double-color indicator lamp. For example, the bi-color indicator 108 may be yellow when the grain in the grain storage 100 is sufficient and red when the grain in the grain storage 100 is less than 1/5.

The grain discharge passage 400 is provided with a grain clamping detection element 401, and the grain clamping detection element 401 is electrically connected with a grain clamping indicator lamp. In a preferred embodiment, the grain clamping indicator lamp is arranged at the periphery of the outlet 11, and when grain is clamped, the grain clamping indicator lamp is turned on to warn the grain clamping state.

Referring to fig. 13, the housing 10 of the large-capacity pet food dispensing device is provided with a manual switch 70, and the manual switch 70 is disposed outside the housing 10 to manually turn on or off the driving motor 210 and the motor 50. When the driving motor 210 is started, the motor 50 is started, the grain discharging passage 400 and the outlet 11 are opened, and grain discharging is realized. And at the same time of turning off the driving motor 210, turning off the motor 50, and further turning off the grain discharging passage 400 and the outlet 11. It should be understood that the driving motor 210 and the motor 50 can be started or stopped by installing a chip in the housing 10 and installing corresponding App software on the smart device. This is a well known technique that should be understood by those skilled in the art and the present invention will not be described in detail.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the present invention pertains, the architecture form can be flexible and varied without departing from the concept of the present invention, and a series of products can be derived. But rather a number of simple derivations or substitutions are made which are to be considered as falling within the scope of the invention as defined by the appended claims.
