Description

Technical Field

[0001] The present disclosure relates to lotus seed processing equipment, and in particular to a beam-type feeding mechanism. Background Art

[0002] Traditional lotus seed processing requires manual labor to pick lotus pods from the fields, separate the lotus seeds from the pods, and then use a special blade to cut and shell the lotus seeds one by one. Since the lotus seeds are wrapped in a translucent skin, which tastes bitter and has no medicinal value, the shelled lotus seeds need to be immersed in water and the skin of the lotus seeds needs to be rubbed off manually. This method of manual labor is cumbersome to operate, labor-intensive, time-consuming and labor-intensive, unhygienic, and very inefficient, and cannot meet market demand.

[0003] With the development of society and the advancement of science and technology, lotus seed crushing, shelling, peeling, core-passing and other processing equipment have emerged. Mechanization and automation are the inevitable development direction of lotus seed processing. However, the existing lotus seed core-passing equipment has a complex structure, and the feeding, positioning and core-passing of lotus seeds are carried out one by one, with low precision and low efficiency, resulting in low processing quality and yield of lotus seeds, high cost, and cannot meet the increasingly high production needs, affecting the application and development of products. Summary of the invention

[0004] The purpose of the present disclosure is to provide a beam-type feeding mechanism, which can solve at least one of the above technical problems. The technical solution of the present disclosure is as follows:

[0005] A beam-type feeding mechanism comprises a first feeding hopper, a first beam and a first driving mechanism. A row of first positioning grooves for matching with lotus seeds are arranged on the top of the first beam along its length direction. The discharge port of the first feeding hopper corresponds to a side surface of the first beam in the length direction. The first driving mechanism can drive the first beam and the first feeding hopper to move up and down relative to each other. As the discharge port of the first feeding hopper is higher than the top of the first beam, the lotus seeds in the first feeding hopper automatically fall into the first positioning grooves.

[0006] In some embodiments, the first driving mechanism drives the first beam to move up and down.

[0007] In some embodiments, the discharge port of the first feed hopper is inclined downward, and a first abutment plate that matches the side surface of the first cross beam is provided at the discharge port of the first feed hopper.

[0008] In some embodiments, a row of first rollers and a first groove body matching the row of first rollers are arranged on the top of the first beam along its length direction, a first groove is arranged on the surface of each first roller along its circumferential direction, and a first positioning groove is formed between two adjacent first rollers.

[0009] In some embodiments, the first crossbeam is provided with first material stopper assemblies respectively matched with two ends of a row of first rollers.

[0010] In some embodiments, a row of first rollers is driven to rotate synchronously by a second driving mechanism, the second driving mechanism includes a first motor, and the first motor drives the row of first rollers to rotate synchronously through a first transmission mechanism.

[0011] In some embodiments, a material return assembly is disposed on a side of the first beam away from the first feeding hopper.

[0012] In some embodiments, the return material assembly includes a return material guide plate that cooperates with the side of the first cross beam. The return material guide plate is arranged to be inclined downward. The discharge port of the return material guide plate is higher than the discharge port of the first feed hopper. A second abutment plate that cooperates with the side of the first cross beam is arranged at the discharge port of the return material guide plate.

[0013] In some embodiments, a row of first material guiding rods is disposed on the return material guide plate, and a first gap for debris to fall is formed between two adjacent first material guiding rods.

[0014] In some embodiments, a rotatable return material baffle is further disposed above the return material guide plate, and the rotatable return material baffle is driven by a third driving mechanism so that the rotatable return material baffle can rotate up and down relative to the return material guide plate.

[0015] The beneficial effect of the present invention is that during use, the lotus seeds to be processed are put into the first feed hopper, and before feeding, the discharge port of the first feed hopper corresponds to and cooperates with a side surface in the length direction of the first beam, and the discharge port of the first feed hopper is lower than the top of the first beam, so that the lotus seeds at the discharge port of the first feed hopper are against the side surface of the first beam, and then the first driving mechanism can drive the first beam and the first feed hopper to move up and down relative to each other. When the discharge port of the first feed hopper is higher than the top of the first beam, the lotus seeds at the discharge port of the first feed hopper automatically fall into a row of first positioning grooves on the top of the first beam. This process is repeated in a cycle, thereby realizing the simultaneous feeding of multiple lotus seeds in a row. The structure is simple and stable, the operation is convenient, the speed is fast, and the precision is high, thereby improving the production efficiency, stability and reliability of the equipment, reducing the cost, being able to meet the increasingly high production needs, and expanding the application and development of the product.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments.

In addition, the terms "first", "second", "superior", "inferior", "primary", "secondary" and the like are used for descriptive purposes only, and can simply be used to more clearly distinguish different components, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0030] See also Figures 1 to 8 As shown, a beam-type feeding mechanism according to the present disclosure is schematically shown, comprising a first feeding hopper 1, a first beam 2 and a first driving mechanism 3. A row of first positioning grooves 201 for matching with lotus seeds is provided on the top of the first beam 2 along its length direction. The number and spacing of a row of first positioning grooves 201 are determined according to specific circumstances. There are usually multiple first positioning grooves 201 in a row.

[0031] The discharge port of the first feed hopper 1 corresponds to a side surface of the first beam 2 in the length direction, and the first drive mechanism 3 can drive the first beam 2 and the first feed hopper 1 to move up and down relative to each other. The first drive mechanism 3 can only drive the first beam 2 to move up and down, or the first drive mechanism 3 can only drive the first feed hopper 1 to move up and down, or two first drive mechanisms 3 can respectively drive the first beam 2 and the first feed hopper 1 to move up and down. The lotus seeds to be processed are fed along the first feed hopper 1, such as Figure 7 As shown, when the discharge port of the first feed hopper 1 is lower than the top of the first beam 2, the discharge port of the first feed hopper 1 corresponds to a side surface of the first beam 2 in the length direction, so that the lotus seeds at the discharge port of the first feed hopper 1 abut against the side surface of the first beam 2. As the first driving mechanism 3 drives the first beam 2 and the first feed hopper 1 to move up and down relative to each other, as shown in FIG. Figure 6 As shown, when the discharge port of the first feed hopper 1 is higher than the top of the first beam 2, the lotus seeds at the discharge port of the first feed hopper 1 automatically fall into a row of first positioning grooves 201 on the top of the first beam 2, and then a driving mechanism drives the first beam 2 and the first feed hopper 1 to move up and down relative to each other, so that the discharge port of the first feed hopper 1 is lower than the top of the first beam 2, waiting for the next feeding, and this process is continuously repeated, thereby realizing the simultaneous feeding of multiple lotus seeds in a row, with fast speed, high precision and high efficiency.

[0032] The first driving mechanism 3 drives the first beam 2 to move up and down, so that the first beam 2 cooperates with the corresponding clamping device to clamp the lotus seeds in the first positioning groove 201, which is more convenient to operate and has higher stability and reliability. The first driving mechanism 3 can be an air cylinder, an oil cylinder, an electric cylinder, a linear module, etc. For example, an air cylinder can be used, which has a simpler and more compact structure, more stable movement, more convenient installation and maintenance, more space-saving installation, and more safety and environmental protection.

[0033] The first slider 25 is provided at both ends of the first beam 2. As the first driving mechanism 3 pushes the first beam 2 to move, the first slider 25 slides synchronously along the first guide rail 6, and the movement is more accurate and more stable. The first guide rail 6 can be rectangular, circular, dovetail or other suitable shapes. The first slider 25 and the first guide rail 6 can adopt linear slide rails or straight slide rails. The first beam 2 is also provided with connecting blocks connected to the first slider 25 at both ends, which are usually connected by fasteners such as screws, which is more convenient for operation and adjustment. The first driving mechanism 3 and the first guide rail 6 are usually installed on the corresponding frame. The frame can also be provided with a buffer matched with the first beam 2, such as an elastic buffer block, an oil pressure buffer, a spring buffer, a polyurethane buffer, etc. The buffer can buffer and protect the movement of the first beam 2, which is safer and more reliable.

[0034] A row of first rollers 21 are arranged at the top of the first crossbeam 2 along its length direction, and a first positioning groove 201 is formed between two adjacent first rollers 21, which is more stable and reliable. A first groove 211 is arranged on the surface of each first roller 21 along its circumferential direction, and usually the first groove 211 is located in the middle of the first roller 21. The first grooves 211 of two adjacent first rollers 21 cooperate to form the first positioning groove 201, and the structure is more compact and stable, and lotus seeds can be placed more stably. A first trough body 22 that cooperates with a row of first rollers 21 is also arranged at the top of the first crossbeam 2, and the lower part of the first roller 21 is located in the first trough body 22, and at least the lotus seed core placed in the first positioning groove 201 is located above the first crossbeam 2, and the structure is more compact and stable.

[0035] The first roller 21 is a flexible roller or has a flexible surface layer, that is, the first roller 21 is a flexible roller or a rubber-coated wheel, such as a silica gel wheel, which can reduce damage to the lotus seeds and facilitate the picking of the lotus seeds.

[0036] A row of first rollers 21 are driven to rotate synchronously by the second driving mechanism 23, so that the lotus seeds in the first positioning groove 201 are oriented and aligned at the same time, which is more efficient, more stable and reliable, and is convenient for subsequent identification, clamping and clamping, and core processing of lotus seeds. The second driving mechanism 23 includes a first motor 231, and the first motor 231 drives a row of first rollers 21 to rotate synchronously through a first transmission mechanism 232. The first motor 231 can be a servo motor, a stepping motor, a reduction motor, a hydraulic motor or other suitable power mechanisms in the prior art, and the first transmission mechanism 232 can be a chain drive, a gear drive, a belt drive or other suitable transmission mechanisms in the prior art. The first crossbeam 2 is also provided with a second slot body 26 for accommodating the first transmission mechanism 232 and a first sealing plate 27 matched with the second slot body 26. The first transmission mechanism 232 is located in the second slot body 26 and is sealed by the first sealing plate 27, which is safer and more reliable.

[0037] The first transmission mechanism 232 adopts a synchronous belt structure. The first transmission mechanism 232 includes a first pulley 2321, a second pulley 2322 and a double-sided synchronous belt 2323 connecting the first pulley 2321 and the second pulley 2322. The first motor 231 is connected to the first pulley 2321. The first pulley 2321 is located at one end of the first beam 2, and the second pulley 2322 is located at the other end of the first beam 2. A toothed wheel structure 212 that matches the double-sided synchronous belt 2323 is provided on each first roller 21. The first roller 21 is meshed with the double-sided synchronous belt 2323 through the toothed wheel structure 212. The first motor 231 drives the first pulley 2321. The first motor 231 cooperates with the first pulley 2321 to drive the double-sided synchronous belt 2323 for transmission. The double-sided synchronous belt 2323 drives all the first rollers 21 to rotate synchronously, so that the lotus seeds in the first positioning groove 201 roll and are oriented. The structure is simple, compact, and stable, and the stability and reliability are higher. Usually, toothed wheel structures 212 are respectively provided at both ends of each first roller 21 , and a first groove 211 is provided between the two toothed wheel structures 212 of each first roller 21 , so that the force is more uniform, more stable and more reliable.

[0038] The first crossbeam 2 is provided with a first material blocking assembly 24 that matches with the two ends of a row of first rollers 21 respectively. The first material blocking assembly 24 can block the lotus seeds in the first positioning grooves 201 at both ends to prevent the lotus seeds from falling, etc., thereby improving the reliability of the equipment. Usually, the first material blocking assembly 24 includes a first baffle 241 and a first baffle 242. The first baffle 241 blocks the entire end of the first crossbeam 2. The first baffle 242 is located on the side of the first baffle 241 close to the first roller 21. The first baffle 242 matches with the first positioning groove 201 located at one end to limit the lotus seeds in the first positioning groove 201, thereby performing double material blocking on the lotus seeds, which is safer and more reliable. The first baffle 242 is also provided with a first curved surface 2421 for matching with the lotus seeds. The first curved surface 2421 can be an inclined surface or an arc surface, etc., which has a better material blocking effect and also has a certain guiding effect.

[0039] The discharge port of the first feed hopper 1 is tilted downward, which is convenient for discharging lotus seeds in the first feed hopper 1. A first abutment plate 11 matching the side of the first beam 2 is provided at the discharge port of the first feed hopper 1. The first abutment plate 11 has an abutment surface parallel to the side of the first beam 2. The abutment surface of the first abutment plate 11 can abut against the side of the first beam 2 to increase the contact area, and the stability and reliability are higher. An appropriate amount of gap can also be left between the abutment surface of the first abutment plate 11 and the side of the first beam 2. The gap is much smaller than the size of the lotus seeds, and the gap can avoid friction between the first beam 2 and the first abutment plate 11 when it moves up and down.

[0040] A first vibrator 15, such as a pneumatic vibrator, an electric vibrator, etc., is also provided at the outer bottom of the first feed hopper 1. The first vibrator 15 enables the first feed hopper 1 to feed better by vibrating. A first discharging bottom plate 12 is provided in the first feed hopper 1. A first abutment plate 11 is located at the outlet of the first discharging bottom plate 12. A first buffer plate 14, such as a sponge plate, a foam plate, a rubber plate, etc., is also provided below the first discharging bottom plate to match it. The first buffer plate 14 has buffering protection and other functions, and can ensure that the first feed hopper 1 vibrates and feeds more stably and reliably. A first cover plate 13 is also provided above the first discharging bottom plate. When the first vibrator 15 vibrates and discharges the first feed hopper 1, the lotus seeds may jump, etc. The first cover plate 13 can block the lotus seeds, which is safer and more reliable.

[0041] A main hopper 5 is also provided above the first feed hopper 1, and the outlet of the main hopper 5 is connected to the inlet of the first feed hopper 1. The double-hopper structure facilitates buffering and transition of the feed, which is more efficient, safer and more reliable.

[0042] After the lotus seeds are fed into a row of first positioning grooves 201 at the top of the first crossbeam 2, the head or tail of the lotus seeds needs to be identified by a corresponding identification device, and then the lotus seeds with inconsistent directions are blown off by the blowing mechanism for blowing selection, so as to ensure that the lotus seeds on the first crossbeam 2 have consistent directions, so as to facilitate the subsequent processing of the lotus seeds. The blowing mechanism can blow the lotus seeds off to a corresponding collecting device, etc., or blow the lotus seeds off to a return material assembly 4, which is arranged on a side of the first crossbeam 2 away from the first feed hopper 1, that is, the return material assembly 4 and the first feed hopper 1 are respectively located on both sides of the first crossbeam 2, and the lotus seeds on the return material assembly 4 can also fall into the first positioning grooves 201 at the top of the first crossbeam 2 during the next feeding, thereby improving efficiency, etc., and being more stable and reliable.

[0043] The return material assembly 4 includes a return material guide plate 41, the discharge port of the return material guide plate 41 cooperates with the side of the first cross beam 2, the return material guide plate 41 is tilted downward, and the two ends of the return material guide plate 41 are respectively fixedly connected to the first support plate 48, and the first support plate 48 also cooperates with the side of the first cross beam 2, and has the functions of supporting and blocking. Figure 7 As shown in FIG. 1 , when the discharge port of the return material guide plate 41 is lower than the top of the first cross beam 2, the discharge port of the return material guide plate 41 corresponds to a side surface of the first cross beam 2 in the length direction, so that the lotus seeds at the discharge port of the return material guide plate 41 abut against the side surface of the first cross beam 2. As the first driving mechanism 3 drives the first cross beam 2 and the first feed hopper 1 to move up and down relative to each other, as shown in FIG. Figure 6 As shown, when the discharge port of the return material guide plate 41 is higher than the top of the first beam 2, the lotus seeds at the discharge port of the return material guide plate 41 automatically fall into a row of first positioning grooves 201 at the top of the first beam 2. The discharge port of the return material guide plate 41 is higher than the discharge port of the first feed hopper 1, so that the lotus seeds on the return material guide plate 41 first fall into the first positioning grooves 201 at the top of the first beam 2 during feeding, so that too many lotus seeds will not accumulate on the return material guide plate 41, which is safer and more reliable.

[0044] A second abutment plate 42 that cooperates with the side surface of the first beam 2 is provided at the discharge port of the return material guide plate 41. The structure of the second abutment plate 42 is basically the same as that of the first abutment plate 11. The second abutment plate 42 also has an abutment surface parallel to the side surface of the first beam 2. The abutment surface of the second abutment plate 42 can abut against the side surface of the first beam 2 to increase the contact area, and the stability and reliability are higher. An appropriate amount of gap can also be left between the abutment surface of the second abutment plate 42 and the side surface of the first beam 2. The gap is much smaller than the size of lotus seeds. The gap can avoid friction between the first beam 2 and the second abutment plate 42 when it moves up and down.

[0045] A row of first guide rods 411 are arranged on the return material guide plate 41. The first guide rods 411 are also arranged obliquely downward and in the same direction as the return material guide plate 41. A first gap 412 for debris to fall is formed between two adjacent first guide rods 411. The size of lotus seeds is much larger than the first gap 412, and they can slide downward along the first gap 412 without being stuck in the first gap 412. The first gap 412 is convenient for the lotus core, water droplets, or other debris that accidentally fall through the core to fall. A corresponding collection box can also be placed under the first gap 412 for collection. The first guide rod 411 can be made of a silicone tube with a hook, which is not only easy to install, but also has a stable and reliable structure, and also has a certain buffering and protective effect on the lotus seeds.

[0046] A second vibrator 47, such as a pneumatic vibrator, an electric vibrator, etc., may also be provided on the outer side of the bottom of the return material guide plate 41. The second vibrator 47 vibrates to enable the return material guide plate 41 to discharge materials better. A buffer plate, such as a sponge plate, a foam plate, a rubber plate, etc., is also provided below the return material guide plate 41. The buffer plate has the functions of buffering and protection, and can ensure that the return material guide plate 41 vibrates and feeds materials more stably and reliably.

[0047] A rotatable return material baffle 43 is also provided above the return material guide plate 41. The lower end of the rotatable return material baffle 43 is connected to the first rotating shaft 45. The first rotating shaft 45 is close to the top of the return material guide plate 41. The third driving mechanism 44 drives the first rotating shaft 45 to rotate, so that the rotatable return material baffle 43 can rotate up and down relative to the return material guide plate 41. When the corresponding blowing device blows and selects the lotus seeds on the top of the first beam 2, as shown in FIG. Figure 7 As shown, the rotatable return material baffle 43 is rotated upward to block the lotus seeds blown off, ensuring that the lotus seeds fall onto the return material baffle. When the corresponding core-passing device etc. processes the lotus seeds, as shown in FIG. Figure 8 As shown, the rotatable return baffle 43 rotates downward so that the top of the rotatable return baffle 43 is substantially flush with or lower than the top of the first beam 2, which facilitates the dropping of lotus seeds after processing.

[0048] The third driving mechanism 44 can adopt a servo motor, a stepper motor, a reduction motor, a hydraulic motor, etc., which can directly drive the first rotating shaft 45 to rotate, or drive the first rotating shaft 45 to rotate through a transmission mechanism such as a worm gear, a synchronous belt mechanism, a gear mechanism, etc. The third driving mechanism 44 can also be a cylinder, an oil cylinder, an electric cylinder, a linear module, etc., which can drive the first rotating shaft 45 to rotate through a rocker rod or a gear rack mechanism. For example, the cylinder drives the rack to move, so that the gear and the first rotating shaft 45 rotate.

[0049] A first stop cloth 46 is also provided on the side of the return material guide plate 41 and the rotatable return material baffle plate 43 away from the first crossbeam 2, and a material drop zone 7 is formed between the first stop cloth 46, the return material guide plate 41 and the rotatable return material baffle plate 43. The material drop zone 7 is convenient for the lotus seeds to be discharged after processing, and the material drop zone 7 is usually connected with the corresponding lotus discharge bucket, collection box, etc. In addition, the crossbeam type feeding mechanism can also be in a double-station or double-sided manner, with two sets of first feeding buckets 1, first crossbeams 2, return material components 4, etc. symmetrically located on both sides of the first stop cloth 46, and the structure is more compact, stable, and more efficient.

[0050] Compared with the prior art, the advantages of the present invention are as follows: the lotus seeds to be processed are fed along the first feeding hopper 1, and before the feeding, the discharge port of the first feeding hopper 1 corresponds to and cooperates with a side surface of the length direction of the first beam 2, and the discharge port of the first feeding hopper 1 is lower than the top of the first beam 2, so that the lotus seeds at the discharge port of the first feeding hopper 1 abut against the side surface of the first beam 2, and the first driving mechanism 3 drives the first beam 2 and the first feeding hopper 1 to move up and down relative to each other, and when the discharge port of the first feeding hopper 1 is higher than the top of the first beam 2, the lotus seeds at the discharge port of the first feeding hopper 1 automatically fall into a row of first positioning grooves 201 at the top of the first beam 2, thereby realizing the simultaneous feeding of multiple lotus seeds in a row, with a simple and stable structure, convenient operation, high speed and high precision, and a first positioning groove 201 is formed between two adjacent first rollers 21, and a row of first rollers 21 are driven to rotate synchronously by the second driving mechanism 23, so that the lotus seeds in the first positioning grooves 201 are simultaneously oriented and straightened. The invention has the advantages of higher efficiency, more stable and reliable, and is convenient for the subsequent identification, pressing and clamping, and core processing of lotus seeds. The first baffle plate 241 and the first baffle sheet 242 of the first material blocking component 24 perform double material blocking on the lotus seeds. The first baffle sheet 242 is also provided with a first curved surface 2421 for matching with the lotus seeds, and the material blocking effect is better. The corresponding blowing mechanism can blow the lotus seeds with inconsistent directions on the first beam 2 to the return material component 4. The rotatable return material baffle plate 43 can be rotated upward to block the blown-off lotus seeds and ensure that the lotus seeds fall onto the return material baffle plate. The discharge port of the return material guide plate 41 is higher than the discharge port of the first feed hopper 1, so that the lotus seeds on the return material guide plate 41 fall into the first positioning groove 201 at the top of the first beam 2 when feeding, so that too many lotus seeds will not be accumulated on the return material guide plate 41, thereby improving the production efficiency, stability and reliability of the equipment, reducing costs, meeting higher and higher production needs, and expanding the application and development of products.

[0051] The above are only some embodiments of the present disclosure, which are only used to illustrate the technical solution of the present disclosure, rather than to limit it. It should be understood that, for those skilled in the art, without departing from the creative concept of the present disclosure, it is possible to make improvements or substitutions according to the above description, and all these improvements and substitutions should fall within the scope of protection of the claims attached to the present disclosure. In this case, all details can be replaced by equivalent elements, and the materials, shapes and sizes can also be arbitrary.
