Description

Technical Field

[0001] This utility model relates to the field of pepper screening, specifically to a pepper conveying device with screening function. Background Technology

[0002] Pepper is a tropical crop that typically grows in warm, humid environments. The fruit of the pepper tree is harvested after ripening and, after simple processing such as removing branches, leaves, and impurities, yields peppercorns. These peppercorns then undergo a series of preliminary processing steps, with sieving being a crucial one. The main purpose of peppercorn sieving is to grade them according to particle size to meet the needs of different customers. Sieving also removes impurities such as stones, soil, and debris, improving the purity and safety of the product. In the early stages of peppercorn sieving, manual sieving or simple mechanical sieving methods are mainly used. These methods are generally inefficient, and the sieving effect is greatly affected by human factors, easily leading to poor sieving results that fail to meet practical application requirements. Based on these technical problems, this invention aims to propose a peppercorn sieving device with better performance. Utility Model Content

The first rotating rod and the second rotating rod are rotatably mounted on the two side walls of the screening box, respectively. The drive shaft is connected to the first rotating rod and the second rotating rod and drives the first rotating rod and the second rotating rod to rotate. The first cam and the second cam are respectively mounted on the first rotating rod and the second rotating rod. The protrusions on the first cam and the second cam are arranged in opposite directions. A fixing plate is provided on both side walls of the screening box. A spring is provided on both fixing plates. The two springs abut against both ends of the second screen.

[0010] Preferably, the drive shaft is connected to the first rotating rod and the second rotating rod respectively via a transmission method consisting of a belt and a pulley.

[0011] Preferably, the transmission assembly includes a rotating shaft, a first end face gear, a second end face gear, a transmission shaft, a crank, a connecting rod, and a slide rod. The rotating shaft is rotatably connected to the screening box. A first rotating rod is driven by the rotating shaft and drives the rotating shaft to rotate. The rotating shaft is provided with a first end face gear. One end of the transmission shaft is provided with a second end face gear that meshes with the first end face gear. The other end of the transmission shaft is provided with a crank. One end of the connecting rod is hinged to the crank. The other end of the connecting rod is hinged to one end of the slide rod.

[0016] Compared with existing technologies, it has the following beneficial effects:

[0017] This utility model provides a pepper conveying device with screening function. In use, the motor is started, and the pepper particles first pass through the first screen in the screening box. The first screen reciprocates in the screening box under the drive of the transmission component. During the reciprocating motion, the pepper particles are evenly distributed on the surface of the first screen, preventing pepper particles from accumulating and improving the screening effect. Pepper particles on the first screen pass through more easily and are less likely to accumulate. Since the first screen is set at an inclination, twigs, leaves and other debris that do not pass through the first screen slide down the first screen under the action of gravity to the discharge port and are discharged from the discharge port on the screening box. After passing through the first screen, the pepper particles continue to move downward and fall into the second screen. The second screen reciprocates under the drive mechanism, causing the pepper particles that fall on the second screen to roll back and forth on the second screen, increasing the contact area with the second screen and making it easier for them to pass through the second screen. Pepper particles are less likely to accumulate on the second screen. The pepper particles that pass through the second screen fall into the collection box at the bottom of the screening box.

[0024] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0025] Example 1:

[0026] like Figures 1 to 4 As shown, this utility model provides a pepper conveying device with screening function, including a screening box 1, characterized in that it further includes:

[0027] The first screen 2 is slidably connected to the screening box 1 and is inclinedly set on the upper part of the screening box 1. The screening box 1 has a discharge port 3 that is aligned with the inclined part of the first screen 2.

[0028] The second screen 5 is rotatably connected to the screening box 1 and located below the first screen 2. A collection box 6 is provided below the second screen 5, and a feed inlet is provided on the screening box 1.

[0029] Drive component 8 is connected to the second screen 5 and drives the second screen 5 to reciprocate.

[0030] The transmission component 9 is connected to the drive component 8 and drives the first screen 2 to slide back and forth.

[0031] This invention provides a pepper conveying device with a screening function. In use, the motor is started, and the pepper particles first pass through the first screen 2 inside the screening box. Driven by the transmission component 9, the first screen 2 reciprocates within the screening box 1. During this reciprocating motion, the pepper particles are evenly distributed on the surface of the first screen 2, preventing accumulation and improving the screening effect. Pepper particles on the first screen 2 pass through more easily, reducing the likelihood of accumulation. Because the first screen 2 is inclined, particles that do not pass through it... Debris such as branches and leaves slide down the first screen 2 under the action of gravity to the discharge port 3 and are discharged from the discharge port 3 on the screening box 1. After passing through the first screen 2, the pepper particles continue to move downward and fall into the second screen 5. The second screen 5 is driven by the drive mechanism 8 to rotate back and forth, so that the pepper particles falling on the second screen 5 roll back and forth on the second screen 5, increasing the contact area with the second screen 5 and making it easier to pass through the second screen 5. The pepper particles are not easy to accumulate on the second screen 5. The pepper particles that pass through the second screen 5 fall into the collection box 6 at the bottom of the screening box 1.

[0032] Example 2:

[0033] like Figures 1 to 4 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, the drive assembly 8 includes a motor 81, a drive shaft 82, a first rotating rod 83, a second rotating rod 84, a first cam 85, a second cam 86, and a spring 87. The first rotating rod 83 and the second rotating rod 84 are rotatably arranged on the two side walls of the screening box 1, respectively. The drive shaft 82 is connected to the first rotating rod 83 and the second rotating rod 84 and drives the first rotating rod 83 and the second rotating rod 84 to rotate. The first cam 85 and the second cam 86 are respectively arranged on the first rotating rod 83 and the second rotating rod 84. The protrusions on the first cam 85 and the second cam 86 are arranged in opposite directions. A fixing plate 88 is provided on both side walls of the screening box 1. A spring 87 is provided on both fixing plates 88. The two springs 87 abut against the two ends of the second screen 5, respectively. The motor 81 drives the first rotating rod 83 and the second rotating rod 84, which are connected to the drive shaft 82, to move. This further drives the cams set on the first rotating rod 83 and the second rotating rod 84. Since the convex parts of the two cams are set in opposite directions on the first rotating rod 83 and the second rotating rod 84, the second screen 5, which abuts against the two cams, is in an inclined state. As the two cams rotate continuously, the two ends of the second screen 5 will exhibit regular alternating up and down movements, allowing the peppercorns to fully contact the second screen 5, increasing the contact area between the second screen 5 and the peppercorns, and making the second screen 5 less prone to clogging. As the second screen 5 is lifted upward by the cams, the abutting part 89 on the second screen 5 will compress the spring 87 on the fixed plate 88. Driven by the elastic force of the spring 87, the second screen 5 will return to the initial position.

[0034] Furthermore, the drive shaft 82 is connected to the first rotating rod 83 and the second rotating rod 84 respectively via a belt and pulley transmission method. This belt and pulley transmission method improves transmission efficiency.

[0035] Furthermore, the transmission assembly 9 includes a rotating shaft 91, a first end face gear 92, a second end face gear 93, a transmission shaft 94, a crank 95, a connecting rod 96, and a slide rod 97. The rotating shaft 91 is rotatably connected to the screening box 1. The first rotating rod 83 is tractively connected to the rotating shaft 91 and drives the rotating shaft 91 to rotate. The first end face gear 92 is provided on the rotating shaft 91. One end of the transmission shaft 94 is provided with a second end face gear 93 that meshes with the first end face gear 92. The other end of the transmission shaft 94 is provided with a crank 95. One end of the connecting rod 96 is hinged to the crank 95. The other end of the connecting rod 96 is hinged to one end of the slide rod 97. The screening box 1 is provided with a through hole for the slide rod 97 to pass through. The other end of the slide rod 97 is connected to the first screen 2. Since the rotating shaft 91 is connected to the first rotating rod 83, the rotation of the first rotating rod 83 will drive the rotating shaft 91 to move. The rotation of the rotating shaft 91 will drive the second end face gear 93, which meshes with the first end face gear 92 on the rotating shaft 91, to move. This will further drive the crank 95 on the transmission shaft 94 to rotate. The rotation of the crank 95 will drive the connecting rod 96, which is hinged to it, to move. This will further drive the slide rod 97 to move. The reciprocating motion of the slide rod 97 will drive the reciprocating motion of the first screen 2 to move.

[0036] Furthermore, the first rotating rod 83 is connected to the rotating shaft 91 via a transmission method using a belt and pulley. This belt and pulley transmission method improves transmission efficiency.

[0037] Furthermore, guide plates 4 are inclinedly arranged on both side walls of the screening box 1. The guide plates 4 are positioned between the first screen 2 and the second screen 5, so that the pepper particles falling from the first screen 2 can more easily fall into the second screen 5 under the guidance of the guide plates 4.

[0038] Furthermore, both ends of the first screen 2 are provided with blocking parts 12, and the screening box 1 is provided with a sliding groove 10 for the first screen 2 to slide. The blocking parts 12 on the first screen 2 prevent pepper particles from rolling out of the filtering range of the first screen 2, and the sliding groove 10 on the screening box 1 facilitates the movement and cooperation between the first screen 2 and the screening box 1.

[0039] Furthermore, the feed inlet is a guide funnel 11. The guide funnel 11 in the screening box 1 facilitates the feeding of pepper granules.

[0040] The working principle of a pepper conveying device with screening function as described in this application is as follows:

[0041] In use, peppercorns first pass through the first screen 2 of the screening box 1. After being filtered by the first screen 2, impurities such as twigs and leaves in the peppercorns are discharged from the discharge port 3 on the screening box 1. The peppercorns that have been filtered by the first screen 2 continue to move downwards under the action of gravity and fall into the second screen 5. Through the filtration of the second screen 5, large peppercorns are separated from small peppercorns, meeting the user's needs. Through the above filtration method, impurities in peppercorns and large peppercorns and small peppercorns can be quickly separated, improving the screening efficiency of peppercorns and making the screened peppercorns better meet the actual production needs.

[0042] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
