For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] According to a first aspect of the present invention, there is provided an automatic stone removal device for a seed melon machine, such as Figures 1 to 4 As shown, the automatic stone removal device for the seed melon machine is used for the seed melon machine, and the automatic stone removal device for the seed melon machine includes a shell 1 and a stone removal mechanism 3.

[0029] In the following description, reference will be made to Figures 1 to 4 The detailed structures of the housing 1 and the stone-removing mechanism 3 of the automatic stone-removing device for the seed melon machine are described in detail.

[0030] like Figures 1 to 4 As shown, in the embodiment, the shell 1 is used as the overall shell of the automatic stone discharge device for the seed melon machine, and can be used for the installation of the stone discharge mechanism 3. At the same time, the shell 1 is provided with a seed melon channel 2 inside. The seed melon channel 2 can be understood as a process channel through which the seed melon enters from the entrance of the seed melon machine, passes through the seed melon channel 2, and is finally discharged. In the seed melon channel 2, the seed melon needs to pass through the following melon cutting mechanism 5, melon pressing mechanism 6, discharge port 4 and material conveying cylinder 7 in sequence, so that the seed melon completes the operation of cutting and pressing melon. The lower part of the shell 1 is provided with a discharge port 4 connected to the seed melon channel 2, and this discharge port 4 can discharge stones from the seed melon channel 2.

[0031] The stone discharge mechanism 3 may include a movable plate 301 and an adjustment assembly, wherein the movable plate 301 is rotatably disposed at the discharge port 4, and the movable plate 301 can close or open the discharge port 4. When the automatic stone discharge device for the seed melon machine does not detect stones, the movable plate 301 closes the discharge port 4, and when the automatic stone discharge device for the seed melon machine detects stones, the movable plate 301 is separated from the discharge port 4, so that the stones are discharged from the discharge port 4. The movable plate 301 may be rotatable in a manner such that, for example, one end of the movable plate 301 is disposed at one end of the discharge port 4 via a rotating shaft, and the movable plate 301 can be rotated with the rotating shaft as the rotation center.

[0032] The adjustment assembly of the stone discharge mechanism 3 may include a first detection member 302 and a control member electrically connected to each other, the first detection member 302 being arranged on the movable plate 301 to detect the pressure in the seed melon channel 2, and the control member being connected to the movable plate 301 to drive the movable plate 301 to rotate. The first detection member 302 may be, for example, a pressure sensor, and the control member may be, for example, a telescopic member. In the embodiment, a cylinder 303 is adopted, and the telescopic rod of the cylinder 303 can be connected to the movable plate 301, and the movable plate 301 is driven to rotate with the rotating shaft as the rotation center through the telescopic rod. The detection process of the first detection member 302 is as follows: when the seed melon passes through the discharge port 4, the seed melon here will be simultaneously subjected to the pressure of the melon pressing mechanism 6, so that the seed melon will be crushed, and the crushing pressure can be transmitted to the movable plate 301 which closes the discharge port 4 at this time. Under normal circumstances, the pressure to crush the seed melon is within the range of 0-1000N, and when the stone passes between the melon pressing mechanism 6 and the discharge port 4, a pressure far greater than that required to crush the seed melon will be generated, and the maximum value can reach 15000N. Therefore, if the pressure detected by the first detection member 302 exceeds the set threshold, it is determined that a stone has entered, and an electrical signal is transmitted to the cylinder 303. The cylinder 303 is actuated to drive the movable plate 301 to rotate, opening the discharge port 4, and the stone will be discharged directly from the discharge port 4.

[0033] The automatic stone discharge device for the seed melon machine is provided with a stone discharge mechanism 3 on the shell 1, a seed melon channel 2 is provided inside the shell 1, and a discharge port 4 connected to the seed melon channel 2 is opened at the lower part of the shell 1, so that the seed melon feeding process can be smooth, and the first detection member 302 of the stone discharge mechanism 3 can be used to detect whether there are stones when the seed melon is fed, and if there are no stones, the seed melon is cut and crushed normally, and if there are stones, the stones can be discharged from the discharge port 4. The automatic stone discharge device for the seed melon machine has a simple overall structure and is easy to operate. It can determine whether there are stones during the feeding process in a simple and direct way, protecting the various parts of the seed melon machine; if there are stones, the stones and other foreign objects can be quickly discharged, saving time and effort without manual intervention; and the entire production process can meet non-stop operation, ensuring production efficiency.

[0034] Preferably, if Figure 3 and Figure 4As shown, in the embodiment, there are multiple stone discharge mechanisms 3, and multiple stone discharge mechanisms 3 are all arranged at the lower part of the housing 1, and the discharge port 4 corresponds to the multiple movable plates 301 of the stone discharge mechanisms 3. In order to ensure accurate detection, the discharge port 4 can correspond to multiple movable plates 301 that act separately. If a pressure detection abnormality occurs on one movable plate 301, only the movable plate 301 with the abnormality is separated from the discharge port 4. If a pressure detection abnormality occurs on multiple movable plates 301, then the multiple movable plates 301 with the abnormality are separated from the discharge port 4, thereby improving the accuracy of detection; at the same time, since only the movable plate 301 with the abnormality is moved, the opening degree of the discharge port 4 can be correspondingly reduced, thereby reducing the discharge of normal seed melon materials and avoiding waste.

[0035] Preferably, if Figures 1 to 4 As shown, in the embodiment, the movable plate 301 can be switched between the open state and the closed state by the control member, and when the movable plate 301 is in the open state, a discharge port 901 is formed between the discharge port 4 and the movable plate 301. Stones are discharged through the discharge port 901. Further, the housing 1 may also include a discharge channel 902 disposed at the lower part of the housing 1, and the discharge channel 902 can be connected to the discharge port 901. The discharge channel 902 can be formed as a channel with a bell mouth, for example, and can receive foreign matter such as stones discharged through the discharge port 901.

[0036] Preferably, if Figure 2 As shown, in the embodiment, the melon seed channel 2 may include a melon cutting mechanism 5, a melon pressing mechanism 6 and a material conveying cylinder 7, which are sequentially arranged along the conveying direction of the material, and the discharge port 4 is arranged below the melon pressing mechanism 6. The melon pressing mechanism 6 can cooperate with the movable plate 301 that closes the discharge port 4 to crush the melon seed. The material conveying cylinder 7 can receive the crushed melon seed material and transmit the crushed melon seed material to the next process.

[0037] Preferably, if Figures 1 to 4 As shown, in the embodiment, a connecting bracket 8 is provided at the lower part of the housing 1, and the control member is connected to the movable plate 301 through the connecting bracket 8. The connecting bracket 8 can be formed into a structure similar to a triangular frame, and the triangular frame has stability.

[0038] Furthermore, if Figure 4As shown, the control member may include a cylinder 303, a first connecting rod 304, a second connecting rod 305 and a third connecting rod 306. The cylinder 303 is connected to the middle of the first connecting rod 304. The second connecting rod 305 and the third connecting rod 306 are both hinged to the first connecting rod 304. A group of second connecting rods 305 and third connecting rods 306 are respectively provided at both ends of the first connecting rod 304. The second connecting rod 305 is hinged to the movable plate 301, and the third connecting rod 306 is hinged to the connecting bracket 8. In this way, the cylinder 303 drives the first connecting rod 304, and the first connecting rod 304 drives the second connecting rod 305 to pull the movable plate 301, and the third connecting rod 306 can play a role of limiting.

[0039] The automatic stone discharge device for the seed melon machine is provided with a stone discharge mechanism on the shell, a seed melon channel is provided inside the shell, and a discharge port connected to the seed melon channel is opened at the lower part of the shell, so that the seed melon feeding process can be smooth, and the first detection part of the stone discharge mechanism can detect whether there are stones when the seed melon is fed, and if there are no stones, the seed melon is cut and crushed normally, and if there are stones, the stones can be discharged from the discharge port. The automatic stone discharge device for the seed melon machine has a simple overall structure and is easy to operate. It can determine whether there are stones during the feeding process in a simple and direct way, protecting the various parts of the seed melon machine; if there are stones, the stones and other foreign objects can be quickly discharged, saving time and effort without manual intervention; and the entire production process can meet non-stop operation, ensuring production efficiency.

[0040] In addition, according to the second aspect of the present invention, a stone removal method for a seed melon machine is provided, and the stone removal method for a seed melon machine includes the automatic stone removal device for a seed melon machine as described above. The seed melon machine may include a melon cutting mechanism 5, a melon pressing mechanism 6, a material removal trough 903, a threshing cylinder (not shown), a pulp throwing mechanism (not shown), a power mechanism (not shown) and a central controller (not shown), and the structures not shown may all be components in the prior art, and will not be described here.

[0041] See also Figures 1 to 4 In an embodiment, the stone removal method for the melon seed machine includes:

[0042] The first step is to determine that the seed melon machine is in working mode, and the material passes through the seed melon channel 2;

[0043] In the second step, when the melon seed machine is in working mode, it has a normal feeding state and a stone entry state. The material passes through the melon seed channel 2, and the melon pressing mechanism 6 can press the material together with the movable plate 301. The material at this time may be melon seed or melon seed mixed with stones. The first detection member 302 can detect the pressing pressure. When the pressure is 0-1000N, the melon seed machine is in a normal feeding state, and the movable plate 301 closes the discharge port 4. The melon pressing mechanism 6 and the movable plate 301 can crush the material, and the crushed material passes through the melon seed channel 2 and enters the threshing drum. When the pressure is greater than 1000N, the melon seed machine is in a stone entry state, and the control member drives the movable plate 301 to rotate, so that the movable plate 301 is separated from the discharge port 4, and the material mixed with stones is discharged through the discharge port 4.

[0044] Preferably, the melon pressing mechanism 6 includes a melon pressing roller 601 and a second detection member (not shown), the second detection member can be, for example, a rotation speed sensor in the prior art, and the second detection member is arranged on the melon pressing roller 601 to detect the rotation speed of the melon pressing roller 601. The melon cutting mechanism 5 can include a melon cutting knife 501 and a third detection member (not shown), the third detection member can be, for example, a rotation speed sensor in the prior art, and the third detection member is arranged on the melon cutting knife 501 to detect the rotation speed of the melon cutting knife 501. The pulping mechanism can include a pulping barrel and a fourth detection member (not shown), the fourth detection member can be, for example, a rotation speed sensor in the prior art, and the fourth detection member is arranged on the pulping barrel to detect the rotation speed of the pulping barrel. The power mechanism may include an engine and a fifth detection member (not shown). The fifth detection member may be, for example, a speed sensor in the prior art. The fifth detection member is arranged on the engine to detect the speed of the engine. When the speed of the melon cutting knife 501 is greater than one hundred revolutions per minute, the speed of the melon pressing roller 601 is greater than one hundred revolutions per minute, the speed of the pulping drum is greater than one hundred revolutions per minute, and the speed of the engine is greater than four hundred revolutions per minute, it is determined that the melon seed machine is in working mode.

[0045] Preferably, if Figures 1 to 3 As shown, in an embodiment, the seed melon machine may further include a sixth sensor (not shown), which is disposed in the material discharge trough 903. The sixth sensor may be, for example, a position sensor, capable of detecting the position of the material in the material discharge trough 903.

[0046] When the movable plate 301 is separated from the discharge port 4, after the material is discharged through the discharge port 4, the movable plate 301 is reset, and the seed melon machine switches from the stone entry state to the normal feeding state, and the stone enters the discharge trough 903. When the material in the discharge trough 903 is full, the sixth sensor sends an alarm signal. The user can receive this alarm signal and then clean the discharge trough 903.

[0047] Preferably, if Figure 3 and Figure 4As shown, in an embodiment, the melon seed machine may include multiple stone discharge mechanisms 3, one discharge port 4 corresponds to multiple movable plates 301 of the stone discharge mechanisms 3, and the first detection member 302 of each stone discharge mechanism 3 can detect the compacting pressure individually; when a stone discharge mechanism 3 has a detection abnormality, the stone discharge mechanism 3 with the detection abnormality drives its movable plate 301 to separate from the discharge port 4, and when multiple stone discharge mechanisms 3 have a detection abnormality, the multiple stone discharge mechanisms 3 with the detection abnormality drive the movable plates 301 to separate from the discharge port 4, so that the corresponding movable plates 301 can be moved according to the position of the stone, thereby preventing the melon seed materials on the remaining movable plates 301 from being discharged, thereby avoiding waste.

[0048] Preferably, in the embodiment, the central controller can be, for example, arranged in the cab, as a centralized processing device for various sensor signals, to determine whether stones are fed in the working state, to timely control the discharge of stones, and to timely send information for the operator to judge. The central controller can be electrically connected to the first detection member 302, and the central controller receives the signal of the first detection member 302 with an operating cycle of 20ms to perform stone discharge detection.

[0049] In an embodiment, a specific operation logic of the stone removal method for the seed melon machine is:

[0050] The first step is to detect the engine speed and the speed of the working parts, and determine that the melon seed machine is in working mode. The melon seed machine enters the stone discharge detection and can switch between the normal feeding state and the stone entry state;

[0051] In the second step, the central controller receives the signal of the first detection member 302 of the movable plate 301 with an operation cycle of 20ms;

[0052] In the third step, when the melon seed material enters the position of the melon pressing roller 601, the melon pressing roller 601 squeezes the melon seed. The received pressure signal is within a normal range, for example, within 0-1000N, which is a normal crushing force. If it exceeds this threshold, it is determined that there are stones. In addition, the pressure will change suddenly when squeezing the stones, and the maximum pressure value can reach 10000N.

[0053] Step 4: When the central controller detects that the pressure is greater than the threshold, the melon seed machine switches to the stone entry state, and the central controller issues a command to the cylinder 303 to drive the movable plate 301 to adjust the angle. The adjusted angle allows the stones on the movable plate 301 to enter the discharge trough 903.

[0054] Step 5: After the stone falls into the discharge trough 903, the movable plate 301 is reset under the drive of the cylinder 303, and the melon seed conveying continues;

[0055] Step 6: When the material in the discharge chute 903 is full, the sixth sensor sends out an alarm signal, which can be transmitted to the display screen in the cab to prompt the user to handle the problem.

[0056] The stone discharge method of the melon seed machine detects the pressure change on the movable plate 301 to determine whether there is stone feeding, and controls the movable plate 301 through the control component to achieve rapid discharge of stones, and can also ensure the non-stop operation of the melon seed machine and improve the operation efficiency.
