DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] This embodiment provides a peanut shelling machine, which is mainly used to solve the problem of incomplete separation of peanut kernels and peanut shells.

[0028] like Figure 1 and Figure 2As shown, it includes a body 1, wherein the inside of the body 1 includes a first chamber 10 and a second chamber 11 interconnected with the first chamber 10. Specifically, the second chamber 11 is located on the left side of the first chamber 10. Peanut shells are crushed and peanut kernels are stored in the first chamber 10, and the second chamber 11 is used for storing peanut shells.

[0029] Among them, Figure 2 As shown, a feed port 101 is provided on the bottom wall of the first chamber 10, and a feed mechanism 2 connected to the feed port 101 is provided on the machine body 1, wherein the feed mechanism 2 is used to put peanuts with peanut shells into the first chamber 10, and a crushing mechanism for crushing the peanut shells is also provided in the first chamber 10.

[0030] Specifically, in this embodiment, Figure 3 and Figure 4 As shown, the crushing mechanism includes a drum 52, a first shelling screw 521, a second shelling screw 53 and a motor 51 for driving the drum 52 to rotate, wherein the motor 51 is connected to the drum 52 through a rotating shaft 54, and the motor 51 is used to drive the drum 52 to rotate at a high speed; wherein, a plurality of first shelling screws 521 are provided, and the plurality of first shelling screws 521 are installed on the peripheral wall of the drum 52, and the second shelling screws 53 are installed on the side wall of the first chamber 10, as shown in FIG. Figure 3 As shown, when the drum 52 rotates, the first shelling screw 521 can pass through the gap between two adjacent second shelling screws 53. At this time, a shelling gap 531 is formed between the first shelling screw 521 and the second shelling screw 53. In order to crush the peanut shells, it is worth noting that the shelling gap 531 is smaller than the diameter of the peanut shell.

[0031] In order to prevent the peanut kernel from breaking when passing through the shelling gap 531, the shelling gap 531 is larger than the diameter of the peanut kernel.

[0032] Through the above arrangement, when peanuts fall from the feed port 101 to the first chamber 10 above the crushing mechanism, the drum 52 rotates at high speed under the action of the motor 51, thereby driving the first shelling screw 521 to rotate at high speed. When the first shelling screw 521 rotates to the inside of the shelling gap 531, the first shelling screw 521 interacts with the second shelling screw 53 to crush the peanut shell, thereby enabling the peanut kernel to be separated from the peanut shell.

[0033] In order to separate the peanut kernels from the peanut shells, in this embodiment, Figure 2 and Figure 2As shown, it also includes a fan 3, wherein the fan 3 is installed on the body 1, specifically, the wind blown by the fan 3 flows from the first chamber 10 to the second chamber 11, and the wind speed of the fan 3 is adjustable, and a separation net 32 ​​located on the lower side of the drum 52 is provided inside the first chamber 10, wherein the separation net 32 ​​is used to separate the peanut kernels and the peanut shells, and a first drawer 41 located in the first chamber 10 is provided below the separation net 32, wherein the first drawer 41 is used to receive the peanut kernels, and a second drawer 42 is installed inside the second chamber 11, wherein the second drawer 42 is used to store the peanut shells.

[0034] Through the above arrangement, after the peanuts are crushed by the crushing mechanism, the peanut shells and peanut kernels fall downward under the action of gravity. At this time, the fan 3 rotates at a high speed, driving the air flow in the air to cross the first chamber 10 and flow to the side of the second chamber 11. Since the weight of the peanut shells is less than the weight of the peanut kernels, the peanut kernels fall into the first drawer 41 through the separation net 32 ​​under the action of their own gravity, and the peanut shells are blown to the second chamber 11 under the action of the air flow and fall into the second drawer 42.

[0035] In order to increase the circulation speed of the airflow and prevent the peanut shells from flying out of the machine body 1, in this embodiment, Figure 2 As shown, an opening is provided on the side of the second chamber 11 facing the fan 3 and a first protective net 111 is installed at the opening, wherein the aperture of the first protective net 111 is smaller than the diameter of the peanut shell. When the airflow blows the peanut shell from the first chamber 10 to the inside of the second chamber 11, the peanut shell hits the first protective net 111 and then falls into the second drawer 42, thereby storing the peanut shell.

[0036] After the peanuts are crushed by the crushing mechanism, the peanut kernels fall onto the separation net 32. If the peanut kernels come into contact with the edge of the separation net 32, the peanut kernels are at risk of collapsing into the second chamber 11, thereby causing the peanut kernels and peanut shells to mix, resulting in poor separation effect. Therefore, in this embodiment, if Figure 2 As shown, the separation net 32 ​​is arranged at an angle. Specifically, the side of the separation net 32 ​​close to the second chamber 11 is higher, and the side of the separation net 32 ​​close to the fan 3 is lower. It is worth noting here that the "higher" and "lower" used at this time refer to the position of the separation net 32 ​​retaining edge relative to itself, wherein there is an angle α between the separation net 32 ​​and the horizontal plane. In this embodiment, the inclination angle of the separation net 32 ​​is 10°.

[0037] Through the above arrangement, when the peanut shells and peanut kernels fall onto the separation net 32 ​​together, since the separation net 32 ​​is inclined toward the fan 3, even if the peanut kernels collide with the separation net 32 ​​and splash, the peanut kernels will collapse toward the fan 3 to prevent the peanut kernels from falling into the second chamber 11 and mixing with the peanut shells. At this time, the peanut shells fall onto the separation net 32, and are blown into the second chamber 11 by the airflow driven by the fan 3.

[0038] Since the separation net 32 ​​is inclined at an angle to one side of the fan 3, in order to prevent the peanut kernels from splashing onto the blades of the fan 3 and affecting the normal operation of the fan 3, in this embodiment, Figure 2 As shown, a second protective net 31 is installed at the air outlet end of the fan 3, wherein the mesh of the second protective net 31 is smaller than the diameter of the peanut kernel, thereby solving the problem of the peanut kernel splashing into the fan 3.

[0039] In order to realize the installation of the separation net 32, in this embodiment, as Figure 2 As shown, a loading rack 321 is fixedly provided on the inner wall of the first chamber 10 , wherein the separation net 32 ​​is loaded onto the loading rack 321 .

[0040] Through the above arrangement, the separation net 32 ​​can also screen the peanuts that have not been crushed. The peanuts screened here are peanuts with a diameter larger than the mesh of the separation net 32. At this time, the separation net 32 ​​can be pulled out of the first chamber and the peanuts that have not been crushed can be poured back into the feeding mechanism 2 to achieve secondary crushing of the peanuts.

[0041] In this embodiment, if Figure 1 , Figure 2 and Figure 5 As shown, the feeding mechanism 2 includes a mounting seat 21 and a feeding hopper 22 , wherein the mounting seat 21 is fixedly mounted on the top wall of the machine body 1 , and the feeding hopper 22 is mounted on the mounting seat 21 , wherein the leakage port of the feeding hopper 22 is connected to the feeding port 101 .

[0042] Through the above arrangement, during the peanut crushing process, the peanuts are poured into the feed hopper 22, and then fall to the top of the crushing mechanism through the feed port 101, and the crushing mechanism is used to crush the peanut shells.

[0043] In order to make the peanuts poured into the feed hopper 22 fall just above the crushing mechanism, in this embodiment, Figure 2 and Figure 5 As shown, a baffle 6 extending downward is fixedly provided on the top wall of the first chamber 10, wherein a gap is left between the side walls of the baffles 6 on both sides and the end wall of the drum 52, and the gap here can prevent the peanuts from falling downward, and the baffle 6 is used to guide the peanuts to prevent the peanuts from splashing randomly.

[0044] When the peanuts fall into the first chamber 10 above the crushing mechanism, as the first shelling screw 521 rotates at a high speed, the peanuts are easily hit by the first shelling screw 521 and fly upward from the bottom of the feed hopper 22. At this time, the peanuts are easy to collapse and injure people. Therefore, in this embodiment, Figure 5 and Figure 6 As shown, it also includes an opening and closing mechanism 23 for controlling the opening of the feed port 101 , wherein a mounting groove 211 communicating with the feed port 101 is provided at the bottom of the mounting seat 21 , and the opening and closing mechanism 23 is installed in the mounting groove 211 .

[0045] When the peanuts being crushed inside the first chamber 10 reach the upper limit, the opening and closing mechanism 23 closes the feed port 101, thereby preventing the peanuts in the feed hopper 22 from continuing to fall downward, and at the same time preventing the peanuts inside the first chamber 10 from splashing outward. When the opening and closing mechanism 23 opens the feed port 101, the peanuts in the feed hopper 22 can continue to fall into the first chamber 10.

[0046] Specifically, in this embodiment, the opening and closing mechanism 23 includes a first sealing plate 231 and a driving mechanism for driving the first sealing plate 231 to move, wherein the first sealing plate 231 abuts against the top wall of the body 1 to close the feed port 101, and the driving mechanism includes a solenoid valve 24 and a valve stem 241 installed on the solenoid valve 24, wherein the solenoid valve 24 is fixedly installed on the top wall of the body 1, and the other end of the valve stem 241 is fixedly connected to the first sealing plate 231.

[0047] Through the above arrangement, when the solenoid valve 24 is energized, the solenoid valve 24 drives the valve stem 241 to retract inward, thereby driving the first blocking plate 231 to move and open the feed port 101; when the feed port 101 needs to be closed, the power to the solenoid valve 24 can be disconnected.

[0048] In order to ensure that the first sealing plate 231 closes the feed port 101 when the solenoid valve 24 is powered off, in the present embodiment, a spring 242 is further included, wherein the spring 242 is sleeved on the valve stem 241, one end of the spring 242 is fixedly connected to the housing of the solenoid valve 24, and the other end of the spring 242 is fixedly connected to the first sealing plate 231. When the solenoid valve 24 is powered on, the spring 242 is in a compressed state, and when the solenoid valve 24 is powered off, the spring 242 is in an original length state.

[0049] In order to prevent the peanuts in the feed hopper 22 from leaking out from the gap between the top wall of the mounting groove 211 and the first blocking plate 231, in this embodiment, Figure 5 and Figure 6 As shown, a second blocking plate 232 extending upward is fixedly provided on the first blocking plate 231 , wherein the side wall of the second blocking plate 232 is slidably connected to the inner wall of the mounting groove 211 .

[0050] When the solenoid valve 24 is powered on or off, the second blocking plate 232 and the first blocking plate 231 can be ensured to move stably. Figure 5 and Figure 6 As shown, the mounting seat 21 is also provided with a slide groove 212, and the second sealing plate 232 is fixedly provided with a slider 233 inserted into the slide groove 212, wherein the side wall of the slider 233 is slidably connected to the side wall of the slide groove 212 to achieve stable movement of the first sealing plate 231 and the second sealing plate 232.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
