Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a food processing raw material conveying device. Background Technology

[0002] In the processing of nut products, particularly in the material handling stage of pine nut processing, inclined screw conveyors are widely used for material lifting and conveying. The screw conveyor's feed end is equipped with a feeding hopper as a material introduction component. When pine nut raw materials are manually fed, workers use shovels to lift the material and pour it into the feeding hopper.

[0003] In actual workshop material feeding operations, influenced by operating habits and work rhythms, workers often unintentionally bump or impact the upper edge of the feeding hopper with the shovel head during repeated shoveling and feeding. The feeding hopper itself is a thin-shell component with limited overall wall thickness, resulting in relatively weak impact resistance. Long-term, repeated impacts from the shovel will gradually cause the upper edge of the feeding hopper to dent, warp, and deform, distorting the hopper's outline. This deformation alters the material feeding direction, making it prone to jamming and spillage when feeding pine nuts. Once irreversible deformation and cracking occur in the feeding hopper, repair and correction are difficult, often requiring complete disassembly and replacement of the entire hopper, shortening the actual service life of the components. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a food processing raw material conveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a food processing raw material conveying device, comprising a base frame, an inclined conveying cylinder arranged on the upper side of the base frame, a feeding bin installed at the lower part of the outer surface of the conveying cylinder, a discharge pipe installed at the upper part of the outer surface of the conveying cylinder, a screw rod rotatably mounted inside the conveying cylinder, a power component for driving the screw rod to rotate inside the conveying cylinder installed at the upper end of the conveying cylinder, and a support ring concentrically arranged with the feeding bin fitted on the feeding bin, the support ring being connected to the base frame. The feeding hopper has a top ring on its upper side for supporting the shovel. Three pillars are evenly installed on the lower surface of the top ring. Multiple vertical holes are equidistantly spaced in a ring on the upper surface of the top ring. The lower ends of the pillars pass through these vertical holes. A slidable pad is fitted onto each pillar, and an adjusting nut is threaded onto the upper side of the pad. A first compression spring is installed between the vertical holes and the pad, and is fitted onto the pillar. A cut-off device is installed between one of the pillars and the power unit to cut off the rotation power of the screw rod in case of power source failure. The feeding hopper is externally equipped with a top ring and a support ring. The impact force of the shovel feeding is absorbed by the top ring and buffered by the pillars and the first compression spring, preventing the impact force from being directly transmitted to the feeding hopper. This protects the feeding hopper from damage and reduces the frequency of maintenance and replacement. Simultaneously, when the shovel impacts and presses down on the top ring, the cut-off device is activated, mechanically pushing the transmission belt to disengage and cut off the power to the screw rod. This avoids production abnormalities caused by transmission belt slippage and idling, making it suitable for continuous manual feeding conditions in food processing plants.

[0006] Specifically, the power component includes a motor. The motor is mounted on the upper part of the outer surface of the conveying cylinder, and is located on the side of the conveying cylinder opposite to the discharge pipe. A small pulley is mounted on the output shaft of the motor, and a large pulley is mounted on the end of the screw rod located outside the conveying cylinder. The large pulley is connected to the small pulley via a transmission belt. The transmission belt has overload buffering capacity; when encountering large foreign objects that cause obstruction, the transmission belt can slip, preventing the motor from being burned out due to hard overload. The motor is located on the upper part of the conveying cylinder, away from the dust and raw material splashing areas of the feeding hopper.

[0007] Specifically, the cutting component includes a deflector rod. A deflector rod is located on one side of the conveyor cylinder, arranged parallel to the conveyor cylinder. A rod head is mounted on the upper end of the deflector rod, and the rod head has an L-shaped structure. The end of the rod head away from the deflector rod extends to the inside of the transmission belt. Multiple horizontal holes are evenly distributed on the outer surface of the deflector rod, and guide rods are inserted into these holes. One end of the guide rod is connected to the conveyor cylinder. A linkage assembly is installed at the lower end of the deflector rod, which cooperates with a column rod to move the deflector rod along the guide rod. When material feeding causes an impact, the column rod presses down, driving the linkage assembly to move the deflector rod along the guide rod. The rod head pushes into the inside of the transmission belt. If the transmission belt is not sufficiently tensioned, it directly disengages from the large and small pulleys, cutting off the power transmission from the motor to the screw rod. The screw rod immediately stops rotating. The guide rod constrains the deflector rod to move only in a straight line, preventing deflection and jamming.

[0008] Specifically, the linkage assembly includes a pressure seat. The end of the actuating rod away from the rod head is fitted with the pressure seat. The side of the pressure seat facing the column has an inclined surface. The lower end of one column slides in contact with the inclined surface. A circular hole is formed on one side of the pressure seat, arranged parallel to the guide rod. A horizontal column is inserted into the circular hole. One end of the horizontal column is connected to the support ring via a hanging plate. An end plate is installed at the end of the horizontal column away from the hanging plate. A second compression spring is provided between the end plate and the circular hole, and the second compression spring is sleeved on the horizontal column. When the column moves downward, it presses against the inclined surface of the pressure seat, converting the vertical impact force into a horizontal thrust that pushes the actuating rod. The horizontal column and the second compression spring provide a restoring force for the actuating rod. After the impact disappears, the second compression spring pushes the pressure seat back to its original position. Upon the next impact, the hanging plate fixes the horizontal column to the support ring.

[0009] Specifically, the upper surface of the pressure seat is machined with an oblique hole, and the lower end of the actuating rod is installed in the oblique hole. The rod head and the actuating rod are integrally formed, and the cross-section of the rod head is circular. The oblique hole increases the connection range between the actuating rod and the pressure seat, and the circular cross-section design of the rod head prevents the rod head from scratching the transmission belt.

[0010] Specifically, two support plates are installed on the lower surface of the support ring. The support plates are arranged vertically, and their lower ends are connected to the bottom frame. The impact force of the top ring after being hit by the shovel is transmitted to the bottom frame through the column, the support ring, and the support plates in sequence. The feeding hopper only bears the weight of the material itself and does not bear the impact load of the shovel. The vertical arrangement of the support plates provides good resistance to vertical impact and makes them less prone to bending and deformation, ensuring that the top ring always remains concentric with the feeding hopper.

[0011] Specifically, a protective ring is provided on the upper side of the top ring. Multiple threaded heads are equidistantly installed in a ring on the lower surface of the protective ring. Multiple through holes are equidistantly opened in a ring on the upper surface of the top ring. Each threaded head passes through one of the through holes. A positioning nut is threaded to the lower end of each threaded head and is located below the through holes. When the shovel impacts, it first contacts the protective ring, which bears the main wear. The threaded heads and positioning nut allow the protective ring to be detached. After the protective ring is worn down, the positioning nut can be loosened to directly replace the protective ring, eliminating the need to replace the entire top ring and column, thus reducing replacement costs.

[0012] Specifically, the lower surface of the top ring has three blind holes spaced equidistantly in a ring shape. These blind holes are staggered from the through holes, and the upper end of the column is installed within one of the blind holes. Installing the column within the blind holes increases the connection range between the column and the top ring, thus improving the stability of the connection.

[0013] Specifically, a long support and a short support are installed on the upper surface of the base frame. The upper end of the short support is connected to the end of the conveying cylinder near the feeding hopper by bolts, and the upper end of the long support is connected to the end of the conveying cylinder away from the feeding hopper by bolts. The long support and the short support together serve to connect the base frame and the conveying cylinder, so that the conveying cylinder is arranged at an angle.

[0014] Specifically, a pipe connector is installed on the upper part of the outer surface of the conveying cylinder near the short support end. The feeding hopper has a funnel structure that is wider at the top and narrower at the bottom, and the lower end of the feeding hopper is connected to the pipe connector by bolts. Installing the pipe connector on the conveying cylinder facilitates the assembly and disassembly of the feeding hopper and the conveying cylinder.

[0015] The beneficial effects of this invention are:

[0016] A top ring is installed above the feeding hopper as an impact-bearing component against the shovel. When the shovel throws material, the force acts on the top ring, preventing direct impact on the feeding hopper. The top ring is assembled onto the support ring via a column and a first compression spring. The support ring is fixed to the bottom frame and does not rely on the feeding hopper to bear the load. When impacted by the shovel, the first compression spring is compressed, absorbing the impact kinetic energy and preventing the impact force from being directly transmitted to the feeding hopper. This prevents the top of the feeding hopper from denting, warping, and deformation, as well as weld cracking, extending the service life of the feeding hopper and reducing the frequency of feeding hopper alignment, disassembly, and replacement.

[0017] The column is equipped with an adjusting nut and a washer. Rotating the adjusting nut changes the pre-compression of the first compression spring, which adjusts the installation height of the top ring. At the same time, the relative position between the lower end of the column and the inclined surface also changes. When the shovel exerts a large impact force to press down on the top ring, one of the columns moves downward simultaneously. The lower end of the column presses against the inclined surface of the pressure seat, pushing the actuating rod to move along the guide rod, causing the rod head to lift the transmission belt. This makes the transmission belt tend to detach from the large and small pulleys. When the transmission belt tension is insufficient, the transmission belt will fall off under the pressure of the rod head, cutting off the power transmitted from the motor to the auger. This allows the fault of insufficient transmission belt tension to be detected in time. The second compression spring works in conjunction with the column to make the relative position between the pressure seat and the column change with the rise and fall of the column.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Please see Figures 1-8 This invention provides a technical solution: a food processing raw material conveying device, including a base frame 100, an inclined conveying cylinder 200 on the upper side of the base frame 100, a long support 101 and a short support 102 mounted on the upper surface of the base frame 100, the upper end of the short support 102 being connected to the end of the conveying cylinder 200 near the feeding bin 202 by bolts, the upper end of the long support 101 being connected to the end of the conveying cylinder 200 away from the feeding bin 202 by bolts, the long support 101 and the short support 102 together serve to connect the base frame 100 and the conveying cylinder 200, so that the conveying cylinder 200 is arranged in an inclined shape, a pipe joint is installed on the upper part of the outer surface of the end of the conveying cylinder 200 near the short support 102, the feeding bin 202 is a funnel structure that is wider at the top and narrower at the bottom, so that the lower end of the feeding bin 202 is connected to the pipe joint by bolts, which facilitates the assembly and disassembly of the feeding bin 202 and the conveying cylinder 200.

[0035] A discharge pipe 201 is installed at the upper part of the outer surface of the conveyor cylinder 200. A screw rod 204 is rotatably installed inside the conveyor cylinder 200. A motor 203 is installed at the upper part of the outer surface of the conveyor cylinder 200, and the motor 203 is located on the side of the conveyor cylinder 200 away from the discharge pipe 201. A small pulley 2033 is installed on the output shaft of the motor 203. A large pulley 2032 is installed at the end of the screw rod 204 located outside the conveyor cylinder 200. The large pulley 2032 is connected to a drive belt 2031. Connected to the small pulley 2033, the transmission belt 2031 has overload buffering capability. When encountering large foreign objects that cause obstruction, the transmission belt 2031 can slip, preventing the motor 203 from being burned out due to hard overload. After pine nuts are added into the feeding bin 202, the motor 203 drives the screw rod 204 to rotate in the conveying cylinder 200. Thus, the screw rod 204 transfers the pine nuts from the feeding bin 202 to the discharge pipe 201. Subsequently, the pine nuts discharged from the discharge pipe 201 fall into the high-level collection container.

[0036] The feeding bin 202 is fitted with a support ring 300 arranged concentrically with the feeding bin 202. Two support plates 301 are installed on the lower surface of the support ring 300. The support plates 301 are arranged vertically so that the lower end of the support plates 301 is connected to the bottom frame 100, thus completing the connection between the support ring 300 and the bottom frame 100.

[0037] The upper side of the feeding hopper 202 is provided with a top ring 302 for supporting the shovel. Three blind holes evenly spaced on the lower surface of the top ring 302 each house a column rod 3021. The upper surface of the support ring 300 has multiple vertical holes 305 arranged in a ring at equal intervals. The lower end of the column rod 3021 passes through the vertical holes 305. A washer 3023 is fitted onto the column rod 3021, slidingly engaging with it. An adjusting nut 3022 is located on the upper side of the washer 3023, threadedly connected to the column rod 3021. A first compression spring 303 is positioned between the vertical holes 305 and the washer 3023, and is fitted onto the column rod 3021. The top ring is positioned above the feeding hopper 202. 302 serves as the impact-bearing component of the shovel. When the shovel impacts the material, the force acts on the top ring 302, preventing direct impact on the feeding bin 202. The top ring 302 is assembled on the support ring 300 via the column rod 3021 and the first compression spring 303. The support ring 300 is fixed to the bottom frame 100 and does not rely on the feeding bin 202 to bear the load. When impacted by the shovel, the first compression spring 303 is compressed, absorbing the impact kinetic energy and preventing the impact force from being directly transmitted to the feeding bin 202. This prevents the upper opening of the feeding bin 202 from denting, warping, and deformation, as well as weld cracking, thus extending the service life of the feeding bin 202 and reducing the frequency of adjustment, disassembly, and replacement of the feeding bin 202.

[0038] The top ring 302 has a retaining ring 304 on its upper side. Multiple threaded heads 3042 are installed in a ring at equal intervals on the lower surface of the retaining ring 304. Multiple through holes 3024 are opened in a ring at equal intervals on the upper surface of the top ring 302. The blind holes and through holes 3024 are staggered. The multiple threaded heads 3042 pass through the multiple through holes 3024 respectively. The lower end of the threaded head 3042 is threadedly connected to a positioning nut 3041. The positioning nut 3041 is located on the lower side of the through hole 3024. When the shovel hits, it first contacts the retaining ring 304. The retaining ring 304 bears the main wear. The threaded heads 3042 and the positioning nut 3041 make the retaining ring 304 detachable. After the retaining ring 304 is worn by impact, the positioning nut 3041 can be loosened to directly replace the retaining ring 304. It is not necessary to replace the entire top ring 302 and the column rod 3021, thus reducing the cost of parts replacement.

[0039] A lever 400 is provided on one side of the conveyor cylinder 200. The lever 400 is arranged parallel to the conveyor cylinder 200. A lever head 402 is installed on the upper end of the lever 400. The lever head 402 has an L-shaped structure and is integrally formed with the lever 400. The cross-section of the lever head 402 is circular. The end of the lever head 402 away from the lever 400 extends to the inner side of the transmission belt 2031. Multiple transverse holes are evenly opened on the outer surface of the lever 400. A guide rod 401 is inserted into the transverse holes. One end of the guide rod 401 is connected to the conveyor cylinder 200. A pressure seat 500 is installed on the end of the lever 400 away from the lever head 402. The upper surface of the pressure seat 500 is machined with an oblique hole so that the lower end of the lever 400 is installed in the oblique hole, thereby improving the stability of the connection between the lever 400 and the pressure seat 500.

[0040] The pressure seat 500 has an inclined surface 501 machined on the side facing the column 3021. The lower end of one column 3021 slides in contact with the inclined surface 501. A circular hole 503 is opened on one side of the pressure seat 500. The circular hole 503 is arranged parallel to the guide rod 401. A horizontal column 502 is inserted into the circular hole 503. One end of the horizontal column 502 is connected to the support ring 300 through a hanging plate 5023. An end plate 5021 is installed on the end of the horizontal column 502 away from the hanging plate 5023. A second compression spring 5022 is provided between the end plate 5021 and the circular hole 503. The second compression spring 5022 is sleeved on the horizontal column 502. An adjusting nut 3022 and a washer 3023 are provided on the column 3021. Rotating the adjusting nut 3022 can change the pre-compression amount of the first compression spring 303, which can adjust the installation height of the top ring 302. At the same time, the lower end of the column 3021 slides in contact with the inclined surface 501. The relative positions between 1 and 2 also change. When the shovel generates a large impact force to press down on the top ring 302, one of the pillars 3021 moves downward synchronously. The lower end of the pillar 3021 presses against the inclined surface 501 of the pressure seat 500, pushing the actuating rod 400 to move along the guide rod 401, causing the rod head 402 to lift the transmission belt 2031, making the transmission belt 2031 tend to detach from the large pulley 2032 and the small pulley 2033. When the tension of the transmission belt 2031 is insufficient, the transmission belt 2031 will fall off under the pressure of the rod head 402, cutting off the power transmitted from the motor 203 to the screw rod 204, so that the fault of insufficient tension of the transmission belt 2031 can be detected in time. The second compression spring 5022 and the pillar 3021 cooperate with each other to make the relative position of the pressure seat 500 and the pillar 3021 change with the rise and fall of the pillar 3021.

[0041] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
