Description

Technical Field

[0001] This utility model relates to the field of pepper processing technology, and in particular to a pepper threshing machine. Background Technology

[0002] Pepper is a common seasoning in people's lives and is known as the "king of tropical spices". In the traditional production of black and white pepper, the stems and seeds need to be separated to obtain the seeds for further processing. Currently, the separation of pepper kernels from stems is mainly done manually. To address this issue, Chinese Patent Publication No. CN209314348U discloses a pepper threshing machine, which includes a feeding hopper, a kernel-stem separation hopper, and a threshing mechanism. The feeding hopper has a discharge port at its bottom, and the kernel-stem separation hopper is located at the bottom of the feeding hopper, with a discharge port at its bottom and a stem outlet at the end furthest from the discharge port. The threshing mechanism includes a mounting shell, a screw rod, a drive unit, a screen sleeve, and a power fan. The mounting shell is located between the feeding hopper and the kernel-stem separation hopper. The screw rod is horizontally positioned within the mounting shell. The drive unit connects to the screw rod and drives its rotation. The screen sleeve is fitted onto the screw rod, and a receiving interface is located at the end of the screen sleeve near the discharge port. The power fan is installed at the end of the kernel-stem separation hopper near the discharge port.

[0003] However, the aforementioned existing technologies still have the risks of untimely feeding by the screw rod causing blockage of the feed hopper, and the screw rod blades being too sharp and damaging the pepper kernels. Utility Model Content

[0004] The purpose of this invention is to solve the problems of slow feeding and scratching of fruit grains caused by screw rods in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pepper threshing machine includes a frame with a feeding trough. A threshing device is located below the feeding trough and inside the frame. A discharge port is located at the bottom of the frame, and a drive motor is located below the discharge port and connected to the threshing device. A waste discharge port is located on the frame, and the drive motor is electrically connected to an external power source. The threshing device includes a screw rod rotatably connected to the frame and the drive motor. A screen sleeve is provided on the screw rod. A primary screen is located at the feeding trough below the screw rod. Spiral blades are provided on the screw rod, including a first blade and a second blade. The first blade is located at the output end of the feeding trough, and the second blade is located inside the screen sleeve. The pitch of the first blade is smaller than that of the second blade. The spiral blades are composed of metal strips with a circular cross-section. Waste discharge blades are provided on the screw rod.

[0007] Preferably, a transmission assembly is provided between the drive motor and the screw rod. The transmission assembly includes a first transmission wheel and a second transmission wheel. The first transmission wheel is connected to the screw rod, and the second transmission wheel is connected to the output shaft of the drive motor. A transmission belt is provided between the first transmission wheel and the second transmission wheel.

[0008] Preferably, a baffle is provided above the feed trough.

[0009] Preferably, the discharge port includes a first discharge port and a second discharge port. The first discharge port is located below the feed trough. The first discharge port and the second discharge port are funnel-shaped, and the built-in slope of the first discharge port and the second discharge port is 60° to 70°.

[0010] Preferably, a screen plate is provided below the first discharge port, the screen plate is provided with a handle, the screen plate is located inside the frame, and a slide is provided inside the frame, the slide being slidably connected to the screen plate.

[0011] Preferably, the frame is equipped with a vibration motor, the output end of the vibration motor is connected to the frame, and the vibration motor is electrically connected to an external power source.

[0012] Preferably, the bottom of the frame is provided with a number of wheels.

[0013] Preferably, the surface of the helical blade is provided with friction texture.

[0014] The beneficial effects proposed by this utility model are as follows:

[0015] Peppers with stems are piled into the feeding trough, which has a built-in slope, allowing the peppers to slide and gradually fall into the threshing device. At this time, the drive motor starts, driving the screw to rotate. When the peppers fall into the threshing device, the screw blades will feed the peppers by spiraling them in. During the rotation of the screw blades, the centrifugal force generated causes the peppers to rub against the screen sleeve sleeved on the screw, achieving the separation of the peppers and stems. The peppers fall through the screen sleeve and the sieve holes of the primary screen, while the stems are pushed by the screw to the waste discharge blades and discharged and collected through the waste discharge port. In the above process, because peppers with stems occupy a large space, material accumulation in the feed trough can easily occur due to untimely feeding by the screw rod. Therefore, the screw blades are divided into a first blade and a second blade. The pitch of the first blade is smaller than that of the second blade. The first blade is a small-pitch blade located at the output end of the feed trough. The small-pitch first blade can speed up the feeding speed and reduce the risk of material blockage in the feed trough. The second blade is a large-pitch blade. The large-pitch second blade feeds at a slower speed than the first blade, allowing the pepper kernels to rub against the stems and the screen sleeve, achieving full separation of the kernels from the stems. The screw blades are composed of metal strips with a circular cross-section. Existing screw blades are generally flat blades with sharp edges, which can scratch the kernels during actual processing. Using screw blades composed of steel bars with a circular cross-section, the curved surface rubs against the pepper kernels, reducing the risk of scratching during friction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1 to 7A pepper threshing machine includes a frame 1, a feeding trough 2 on the frame 1, a threshing device located below the feeding trough 2 within the frame 1, a discharge port at the bottom of the frame 1, a drive motor 4 below the discharge port connected to the threshing device, a waste discharge port 5 on the frame 1, and an external power supply for the drive motor 4. The threshing device includes a screw rod 6 rotatably connected to the frame 1 and connected to the drive motor 4. A screen sleeve 7 is provided on the screw rod 6, and a primary screen 3 is provided at the feed trough 2. The primary screen 3 is located below the screw rod 6. A screw blade 8 is provided on the screw rod 6. The screw blade 8 includes a first blade 20 and a second blade 21. The first blade 20 is located at the output end of the feed trough 2, and the second blade 21 is located inside the screen sleeve 7. The pitch of the first blade 20 is smaller than that of the second blade 21. The screw blade 8 is composed of metal strips with a circular cross-section. A waste discharge blade 18 is provided on the screw rod 6. Specifically, peppers with stems are piled into the feeding trough 2, which has a built-in slope, allowing the peppers to slide and gradually fall into the threshing device. At this time, the drive motor 4 starts, driving the screw rod 6 to rotate. When the peppers fall into the threshing device, the spiral blades 8 will feed the peppers by spiraling them in. During the rotation of the spiral blades 8, the centrifugal force generated causes the peppers to rub against the screen sleeve 7 sleeved on the screw rod 6, achieving the separation of the peppers and stems. The peppers fall through the screen sleeve 7 and the sieve holes of the primary screen 3, while the stems are pushed by the screw rod 6 to the waste discharge blade 18 and discharged and collected through the waste discharge port 5. In the above process, since the peppers with stems occupy a large space, material accumulation in the feed trough 2 is likely to occur during actual feeding due to the untimely feeding of the spiral rod 6. Therefore, the spiral blade 8 is divided into a first blade 20 and a second blade 21. The pitch of the first blade 20 is smaller than that of the second blade 21. The first blade 20 is a small-pitch blade and is located at the output end of the feed trough 2. The small-pitch first blade 20 can speed up the feeding speed and reduce the risk of material blockage in the feed trough 2. The second blade 21 is a large-pitch blade. The large-pitch second blade 21 has a lower feeding speed than the first blade 20, which allows the pepper berries to rub fully against the stems and the screen sleeve 7, achieving full separation of the berries and stems. The spiral blade 8 is composed of metal strips with a circular cross-section. However, the existing spiral blades 8 are generally flat blades with sharp edges, which can scratch the peppercorns during actual processing. The spiral blades 8, composed of steel bars with a circular cross-section, can reduce the risk of scratching the peppercorns when rubbing against them by using curved surfaces.

[0027] Specifically, a transmission assembly is provided between the drive motor 4 and the screw rod 6. This transmission assembly includes a first transmission wheel 9 and a second transmission wheel 22. The first transmission wheel 9 is connected to the screw rod 6, and the second transmission wheel 22 is connected to the drive motor 4. A transmission belt 10 is provided between the first transmission wheel 9 and the second transmission wheel 22. When the output shaft of the drive motor 4 rotates, it drives the second transmission wheel 22 to rotate, which in turn causes the first transmission wheel 9 on the screw rod 6 to rotate via the transmission belt 10, thus causing the screw rod 6 to rotate. The drive motor 4 and the screw rod 6 are connected through this transmission assembly, optimizing the spatial arrangement of the components of the pepper thresher and solving the problem of equipment footprint.

[0028] Specifically, a baffle 11 is provided above the feeding trough 2. Since peppercorns separate from the stems during the detachment process using centrifugal force and friction, some stems and peppercorns will be thrown out due to centrifugal force during the rotation of the spiral blade 8. Therefore, the baffle 11 needs to be provided on the feeding trough 2 to block the stems and peppercorns in the direction in which they will be thrown out, thereby reducing the risk of splashing.

[0029] Specifically, the discharge outlet includes a first discharge outlet 12 and a second discharge outlet 13. The first discharge outlet 12 is located below the feed trough 2. Both the first discharge outlet 12 and the second discharge outlet 13 are funnel-shaped, and their internal slopes are 60° to 70°. The division of the discharge outlet into the first discharge outlet 12 and the second discharge outlet 13 effectively improves discharge efficiency and reduces the risk of blockage that would occur with a single discharge channel. In existing discharge channels, peppercorns produce juice or impurities due to friction during threshing, which adhere to the discharge channel and hinder discharge. Therefore, the internal slopes of the first discharge outlet 12 and the second discharge outlet 13 need to be set between 60° and 70° to effectively improve the discharge efficiency of the peppercorns.

[0030] Specifically, a screen plate 14 is provided below the first discharge port 12, and a handle 15 is provided on the screen plate 14. The screen plate 14 is located inside the frame 1, and a slide 19 is provided inside the frame 1, with the slide 19 slidably connected to the screen plate 14. In actual threshing operations, the peppers are threshed cleanly at the second discharge port 13 due to the large pitch stroke of the spiral blades 8. However, at the first discharge port 12, peppers accumulate and centrifugal force is insufficient, resulting in incomplete threshing of peppers and stems, with some stems mixed in with the falling pepper grains. Therefore, the screen plate 14 is located inside the first discharge port 12. The screen plate 14 traps the stems, while the pepper grains pass through the screen holes and are discharged from the first discharge port 12, achieving secondary separation of pepper grains and stems. When the fruit stalks accumulate to a certain extent, the operator holds the handle 15 and, with the slide seat 19 and the screen plate 14 slidably connected, pulls the screen plate 14 out of the first discharge port 12, cleans the fruit stalks, and then reinstalls it into the first discharge port 12, which facilitates the cleaning of the screen plate 14.

[0031] Specifically, a vibration motor 16 is installed inside the frame 1. The output end of the vibration motor 16 is connected to the frame 1, and the vibration motor 16 is electrically connected to an external power source. During operation, fruit stalks may become stuck in the sieve plate 14, preventing the fruit from passing through the sieve holes. External force is needed to shake the sieve plate 14 to effectively separate the fruit from the stalks. Therefore, the vibration motor 16 is installed inside the frame 1, causing the frame 1 to vibrate. The sieve plate 14, located inside the frame 1, receives the output from the vibration motor 16. Through vibration, the sieve plate 14 can improve the separation of pepper fruit from the stalks, reducing the risk of stalks getting stuck in the fruit.

[0032] Specifically, the bottom of the frame 1 is equipped with several wheels 17. The wheels 17 facilitate the transportation and movement of the pepper thresher, allowing it to be deployed for operation in different scenarios.

[0033] Specifically, the surface of the spiral blade 8 is provided with friction texture 23. The friction texture 23 is used to increase the friction between the spiral blade 8 and the pepper kernels, which is beneficial to the efficiency of separating the pepper kernels from the stems.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
