Description

Technical Field

[0001] The present invention relates to the technical field of lotus seed production and processing equipment, and particularly to a lotus seed processing production line and a side-arm wing-span type production line sealing and noise elimination device. Background Art

[0002] China is a country rich in lotus seeds in the world. Lotus seeds can be used as both medicine and food and are rich in nutrients. Traditional lotus seed processing, from picking, threshing, shelling, peeling, to core removing, is all manual operation, which is very laborious and has extremely low efficiency.

[0003] The existing lotus seed production line includes steps such as shell breaking, edge opening, classification and screening, and transfer steps. In these machining steps, a large number of vibrating and colliding components will cause a large amount of noise pollution, which is quite unbearable for on-site workers. In the long term, it will seriously cause health hazards such as tinnitus and chest tightness, and will also affect the on-site communication quality of workers and reduce work efficiency. Summary of the Invention

[0004] The purpose of the present invention is, in addition to ensuring the processing scale benefit of the lotus seed production line itself, mainly to overcome the noise pollution problem existing in the prior art, and at the same time solve a series of technical problems such as the sound insulation problem of multi-band noise, the noise elimination efficiency of the sound insulation device, and the installation and maintenance of the sound insulation device.

[0005] It includes a shell-breaking machine cluster composed of at least one shell-breaking mechanism, an edge-opening machine cluster composed of at least one edge-opening mechanism, a shunting and electric screening machine, a classification transfer hopper, and a transfer and shunting device connecting each processing procedure. A side-arm wing-span type production line sealing and noise elimination device is also provided outside the shell-breaking machine cluster, the edge-opening machine cluster, and the shunting and electric screening machine.

[0006] Furthermore, the transfer and diversion device connecting each processing procedure includes a first elevator, a connecting hose, a first conveyor belt, a first diversion hopper, first diversion hopper diversion branch pipes, a second conveyor belt, conveyor belt connecting branch pipes, a second elevator, a second diversion hopper, second diversion hopper connecting branch pipes, a third conveyor belt, an arc-shaped connecting plate, an electric sieve machine discharge pipe, a transfer hopper control valve, and a transfer hopper unloading channel arm. The elevator feed hopper of the first elevator is arranged on the ground. The elevator discharge opening of the first elevator is connected to the transfer hopper through the connecting hose. The outlet of the transfer hopper is arranged on the first conveyor belt. The outlet of the first conveyor belt communicates with the first diversion hopper. The outlet of the first diversion hopper is connected to a plurality of the first diversion hopper diversion branch pipes. The outlets of the first diversion hopper diversion branch pipes are connected to the respective shell-breaking machines. The outlets of the shell-breaking machine clusters formed by the respective shell-breaking machines are arranged on the second conveyor belt. The outlet of the second conveyor belt communicates with the elevator feed hopper. The elevator discharge opening of the second elevator is connected to the second diversion hopper. The outlet of the second diversion hopper is connected to the respective edge-opening machines through the second diversion hopper diversion branch pipes. The outlets of the respective edge-opening machines in the edge-opening machine cluster are arranged on the third conveyor belt. The outlet of the third conveyor belt communicates with the elevator feed hopper of the third elevator. The elevator discharge opening of the third elevator is connected to the inlet of the diversion electric sieve machine through the connecting hose. The outlets of the respective layers of sieves of the diversion electric sieve machine are connected to the inlets of the respective storage hoppers of the classification transfer hopper through the electric sieve machine discharge pipe for storage. A transfer hopper control valve is arranged at the outlet of the classification transfer hopper. The outlet of the classification transfer hopper can be connected to the transfer hopper unloading channel arm. The first conveyor belt is placed on the first platform. The shell-breaking machine cluster is arranged on the second platform. The edge-opening machine cluster is arranged on the third platform.

[0007] Due to the application of the above technical solution, compared with the prior art, a lotus seed processing production line provided by the present invention not only ensures the processing scale benefit of the lotus seed production line itself, but mainly overcomes the problem of noise pollution existing in the prior art, and at the same time solves a series of technical problems such as the sound insulation problem of multi-band noise, the sound absorption efficiency problem of the sound insulation device, and the installation and maintenance of the sound insulation device.

[0008] Further, it includes a bottom sound-absorbing partition, side-arm sound-absorbing partitions, a top sound-absorbing partition, and a lateral sound-absorbing assembly partition. The bottom sound-absorbing partition is installed between the bottom of the processing machine cluster and the platform floor. The lateral sound-absorbing assembly partition is installed at both ends of the processing machine cluster. The top sound-absorbing partition is installed on the lateral sound-absorbing assembly partition. The side-arm sound-absorbing partition is rotatably installed on the top sound-absorbing partition. When the side-arm sound-absorbing partition is in the closed working state, the bottom sound-absorbing partition, side-arm sound-absorbing partitions, top sound-absorbing partition, and lateral sound-absorbing assembly partition soundproof and seal the processing machine cluster. It also includes at least one shunt branch pipe installation hole provided on the top sound-absorbing partition. The shunt branch pipe installation hole is used to connect a shunt branch pipe to convey materials into the processing machine cluster. The position of the shunt branch pipe installation hole can also be installed on the sidewall sound-absorbing partition or the lateral sound-absorbing assembly partition, but it is most convenient and the feeding is the smoothest when installed on the top sound-absorbing partition.

[0009] The shunt branch pipe installation hole is usually provided on the top sound-absorbing partition. However, if a flat assembly line is adopted, it can also be provided on the lateral sound-absorbing assembly partition. The soundproof seal is not a completely sealed state but a state of basically isolating and sealing the noise. The sidewall sound-absorbing partition can be an arc-shaped side-arm sound-absorbing partition or a right-angle side-arm sound-absorbing partition, but it is not limited to this. A flat sound-absorbing partition is also feasible. However, relatively speaking, the arc-shaped side-arm sound-absorbing partition has a larger effective sound-absorbing area at the same height, and the top positions of the right-angle side-arm sound-absorbing partition and the arc-shaped side-arm sound-absorbing partition are higher in the 90-degree open state under the condition of the same-height top sound-absorbing partition, and it is not easy to hit the head when opening. Due to the conduction of solid sound on the ground, only using sound-absorbing partitions to isolate on all sides, the noise conducted along the bottom plane of the processing machine cluster is still not eliminated. Therefore, the structure of the bottom sound-absorbing partition is adopted to block and dissipate this part of the noise pollution in the propagation path.

[0010] Further, the rotational installation method between the side-arm sound-absorbing partition and the top sound-absorbing partition includes one or two of the following methods: a hinge assembly structure, where a sidewall rotating shaft is provided on the top sound-absorbing partition, and the side-arm sound-absorbing partition is installed on the sidewall rotating shaft. When adopting the rotational installation structure of the side-arm rotating shaft, it can be driven by a motor, or the side-arm sound-absorbing partition can be manually flipped to the open state. When manually opening, when using lightweight materials, the manual opening method is convenient and more economical.

[0011] Further, it also includes auxiliary support rods, which are provided at both ends of the top sound-absorbing partition to assist in supporting the side-arm sound-absorbing partition. The auxiliary support rods are used to solve the risk that the side-arm sound-absorbing partition may fall and injure the staff in the open state and strengthen the structural stability in the open state.

[0012] Further, the side arm sound insulation partition is a segmented side arm sound insulation partition. There is a side arm segment rod between each of the segmented side arm sound insulation partitions, and the auxiliary support rod is arranged on the side arm segment rod.

[0013] Further, the type of the side arm sound insulation partition is an arc-shaped side arm sound insulation partition or a right-angle side arm sound insulation partition. The types of the side arm sound insulation partition are not limited to the above two structures and can also be in a straight plate shape. However, relatively speaking, the effective sound insulation area of the arc-shaped side arm sound insulation partition is larger.

[0014] Further, the corner of the side arm sound insulation partition is set as a rounded corner part, and a gasket is arranged at the bottom end of the side arm sound insulation partition.

[0015] Further, the side arm sound insulation partition includes one or a combination of the following two ways with a sound insulation interlayer: a single sound insulation interlayer is arranged in the side wall sound insulation partition; a first sound insulation interlayer and a second sound insulation interlayer are arranged in the side arm sound insulation partition. Setting the interlayer sound insulation can facilitate the replacement of the sound insulation material therein to adapt to different noise situations and is also convenient for maintenance. The design of the double sound insulation interlayer can effectively perform sound insulation processing on noise sources in multiple frequency bands. The sound insulation structure of the interlayer is convenient for the assembly and maintenance of the sound insulation material. Second, since the processing machine cluster itself may have noises in multiple frequency bands, in the case of a double interlayer, corresponding sound insulation materials can also be used for specific frequency band noises, and the overall sound insulation effect is better.

[0016] Further, sound insulation protrusions are arranged on the inner sides of the side arm sound insulation partition, the top sound insulation partition, and the lateral sound insulation assembly partition.

[0017] Further, the surface shape of the sound insulation protrusion is a spherical curved surface or a tetrahedral protrusion, and the distance between the tops of adjacent sound insulation protrusions is set to be a multiple approaching half of the wavelength of the main noise frequency band. In this way, the decibels of specific frequency band noises can be effectively eliminated by using the diffraction superposition of the half wavelength of the wave.

[0018] Due to the application of the above technical solutions, compared with the prior art, the side arm wingspan type production line sealing and sound insulation device provided by the present invention has a simple overall device structure, good noise pollution removal effect, can be lifted with one key for convenient use, and has sufficient internal space. At the same time, a series of technical problems such as the sound insulation problem of multi-band noises, the sound insulation efficiency problem of the sound insulation device, and the trouble of installation and maintenance of the sound insulation device are solved.

[0033] The embodiments of the present invention will be further described below with reference to the attached drawings.

[0034] As Figure 1 This is a schematic diagram of the overall structure of a lotus seed processing production line of the present invention. The main processes for processing lotus seeds in the entire production line include shell-breaking, edge-opening, classification and screening, and storage and unloading processes. Among them, the shell-breaking process is the process of removing the shells of lotus seeds, and the edge-opening process is the process of splitting lotus seeds into two halves and removing the cores. Among them, the shell-breaking process is processed by a shell-breaking machine cluster composed of multiple shell-breaking machines (500), the edge-opening process is processed by an edge-opening machine cluster composed of multiple edge-opening machines (600), the classification and screening process is carried out by a shunting and electro-sieving machine (700), and the storage and unloading process is carried out by a sorting and transfer hopper (800). Figure 1In the middle is the lotus seed production line with a spatial layout to ensure the utilization rate of the overall space and facilitate the transfer and storage of lotus seeds. The shell-breaking machine cluster is set on the second platform (152), the side-opening machine cluster is set on the third platform (153), and the shunt electric sieve machine (700) is set on the third platform (153). A first climbing machine is set before the shell-breaking process. The climbing machine feed hopper (101) of the first climbing machine is set on the ground (150). The climbing machine main body (102) of the first climbing machine is used to transfer lotus seeds to the climbing machine discharge port (103) through a sealed channel. The climbing machine discharge port (103) is connected to the transfer hopper (200) through a connecting hose (104). The outlet of the transfer hopper (200) is set on the first conveyor belt (310). The outlet of the first conveyor belt (310) is set on the first shunt hopper (410). The outlet of the first shunt hopper (410) is connected to multiple first shunt hopper shunt branch pipes (411). The outlets of the first shunt hopper shunt branch pipes (411) are connected to the shell-breaking machines (500) respectively; the outlets of the shell-breaking machine cluster formed by the shell-breaking machines (500) are set on the second conveyor belt (320). The outlet of the second conveyor belt (320) is connected to the climbing machine feed hopper (101) of the second climbing machine through a conveyor connecting branch pipe (108). The climbing machine discharge port (103) of the second climbing machine is connected to the second shunt hopper (420). The outlet of the second shunt hopper (420) is connected to the side-opening machines (600) respectively through second shunt hopper shunt branch pipes (421). The outlets of the side-opening machines (600) in the side-opening machine cluster are set on the third conveyor belt (330). The outlet of the third conveyor belt (330) is connected to the climbing machine feed hopper of the third climbing machine through an arc-shaped connecting plate (109). The climbing machine discharge port (103) of the third climbing machine is connected to the inlet of the shunt electric sieve machine (700) through a connecting hose (104). The outlets of the sieve meshes of each layer of the shunt electric sieve machine (700) are connected to the inlets of the storage hoppers of the classification transfer hopper (800) through electric sieve machine discharge pipes (710) for storage. A transfer hopper control valve (810) is set at the outlet of the classification transfer hopper (800) to control the total on-off of the classification transfer hopper (800). The outlet of the classification transfer hopper (800) can be connected to a transfer hopper unloading channel arm (820). Through the transfer hopper unloading channel arm, the classified lotus seeds can be conveniently unloaded into the loading trolley (830) or other transfer carriers. There is a production line sealing and sound insulation device (900) outside the shell-breaking machine cluster, the side-opening machine cluster, and the shunt electric sieve machine (700). The first conveyor belt (310) is placed on the first platform (151).

[0035] As Figure 4 is a structural schematic diagram of the working state of the arc-shaped side arm wing-span type production line sealing and sound insulation device. As Figure 9It is a schematic top view structural contour diagram of the top sound insulation partition. It includes a bottom sound insulation partition (901), an arc-shaped side arm sound insulation partition (902), and a top sound insulation partition (903). The arc-shaped side arm sound insulation partition (902) is rotatably installed on the top sound insulation partition (903). The rotation installation method can be that the arc-shaped side arm sound insulation partition is installed on the top sound insulation partition (903) through a side arm rotation shaft (909). The top sound insulation partition (903) is installed on the lateral sound insulation assembly partition (904). As Figure 8 shown, the contour of the lateral sound insulation assembly partition (904) matches the contour formed by the arc-shaped side arm sound insulation partition (902) and the top sound insulation partition when in the working state, so as to seal the overall production line sealing and sound insulation device laterally. The side arm rotation shaft (909) can extend out of the lateral sound insulation assembly partition (904). A rotating shaft of a servo motor can be connected outside the side arm rotation shaft (909) to drive the side arm rotation shaft to rotate, so as to switch the side arm wing-span type production line sealing device between the working closed state and the open state. At the same time, at least one monitoring breathing hole (917) is also provided on the lateral sound insulation assembly partition (904) for the staff to monitor the internal operation and for the ventilation hole function. The position of the monitoring breathing hole is at the height of a person standing, which is convenient for observation. As Figure 5 It is a schematic structural diagram of the arc-shaped side arm wing-span type production line sealing and sound insulation device in the open state. When the arc-shaped side arm sound insulation partition (902) is in the open state, the staff can conveniently monitor the operation state of the production line and maintain the machine devices in the production line. As Figure 9 It is a schematic top view structural contour diagram of the top sound insulation partition. At least one shunt branch pipe installation hole (998) is provided on the top sound insulation partition (903). A connecting hose (104) is installed on the shunt branch pipe installation hole (998) for introducing lotus seeds into the processing machine cluster (1000) inside the production line sealing and sound insulation device. The types of the processing machine cluster (1000) include the shell-breaking machine cluster, the edge-opening machine cluster, and the shunt electric sieve machine in the above-mentioned lotus seed production line, but are not limited thereto. Other equipment or equipment clusters that need noise reduction treatment introduced into the lotus seed production line are also set like this. The rotation connection method between the arc-shaped side arm sound insulation partition (901) and the top sound insulation partition (903) can also be a hinge connection method. The specific hinge connection method includes the hinge connection scheme of the double-hinge closure with horizontal direction locking disclosed in the patent number 20168055774.1.

[0036] As Figure 6 It is a side view of the non-segmented side arm wing-span type production line sealing and sound insulation device in the open state. The arc-shaped side arm sound insulation partition (902) is a whole arc-shaped side arm sound insulation partition. When the arc-shaped side arm sound insulation partition (902) is in the open state, it is supported by an auxiliary support rod (919) to strengthen the stability of the support. It is mainly applicable to the situation where the longitudinal distribution of the processing machine cluster is not long.Figure 7 The invention is a side view of a segmented side arm wing span type production line sealing silencer in an open state, wherein the arc-shaped side arm silencer baffle (902) is composed of a plurality of arc-shaped side arm silencer baffles. When each segment of the arc-shaped side arm silencer baffle (902) is in an open state, it is auxiliary supported by an auxiliary support rod (919) to enhance the stability of the support. Usually, each segment of the arc-shaped side arm silencer baffle (902) is supported by two segments of auxiliary support rods (919). An arc-shaped side arm segment rod (905) is arranged between each segment of the arc-shaped side arm silencer baffle. The auxiliary support rod (919) is usually arranged on the lateral silencer assembly baffle (904) and the arc-shaped side arm segment rod (905).

[0037] like Figure 10 Schematic diagram of the structure of the right-angle side arm wing-span type production line sealing and silencer in working state. The main difference between the right-angle side arm wing-span type production line sealing and silencer and the arc-shaped side arm wing-span type production line sealing and silencer is that the side arm is a right-angle side arm silencer baffle (911). Figure 11 This is a schematic diagram of the working state of the wing-type production line sealing silencer with rounded right-angle side arms. Figure 10 The right-angled side arm sound-absorbing partition is further processed with rounded corners, and the right-angled corners of the side wall of the right-angled side arm sound-absorbing partition are processed into rounded corners (913) so that the side arm is a right-angled side arm sound-absorbing partition (912) with rounded corners, thereby avoiding scratches and abrasions on the staff at the corners as much as possible. At the same time, a rubber gasket (916) is set at the bottom end of the right-angled side arm sound-absorbing partition (912) with rounded corners to seal the contact part and prevent friction damage to the contact part when opening and closing.

[0038] like Figure 12 The structure diagram of a single-silence interlayer arc-shaped side arm wing-span type production line sealing silencer is shown in FIG. The arc-shaped side arm wing-span type production line sealing silencer is enhanced and improved on the basis of the arc-shaped side arm wing-span type production line sealing silencer. A single-silence interlayer (923) is provided in the single-silence interlayer arc-shaped side arm silence baffle (922), and a silencer protrusion (927) is provided on the inner side of the single-silence interlayer arc-shaped side arm silence baffle (922), the top silence baffle (903), and the side mounted silence baffle (904). ), the sound-absorbing protrusion (927) is a sound-absorbing material, which can be a sound-absorbing material such as sponge. The surface shape of the sound-absorbing protrusion (927) is a spherical curved surface or a tetrahedral protrusion. The distance between the tops of adjacent sound-absorbing protrusions is preferably close to a multiple of the half wavelength of the main noise frequency band. The noise energy will oscillate and dissipate between these adjacent protrusions. A sound-absorbing interlayer can also be provided in the top sound-absorbing baffle (903). It is provided as an integrated sound-absorbing interlayer. If it is a non-integrated interlayer, it will be difficult to install the sound-absorbing material into the sound-absorbing interlayer after the branch pipe installation hole (998) is provided. Figure 13It is a structural schematic diagram of a double-sound-absorbing sandwich arc-shaped side-arm wing-span type production line sealing and sound-absorbing device, which is an improvement of the sound-absorbing part on the basis of the arc-shaped side-arm wing-span type production line sealing and sound-absorbing device. The double-sound-absorbing layer arc-shaped side-arm sound-absorbing partition board (924) is adopted. The first sound-absorbing sandwich layer (925) and the second sound-absorbing sandwich layer (926) are arranged in the double-sound-absorbing layer arc-shaped side-arm sound-absorbing partition board (924). A sound-absorbing convex part (927) is also arranged on the inner sides of the double-sound-absorbing layer arc-shaped side-arm sound-absorbing partition board (924), the top sound-absorbing partition board (903), and the lateral assembly sound-absorbing partition board (904). The sound-absorbing convex part (927) is a sound-absorbing material, which can be a sound-absorbing material such as sponge. The surface shape of the sound-absorbing convex part (927) is a spherical surface or a tetrahedral convex. The distance between the tops of adjacent sound-absorbing convex parts preferably adopts a multiple approaching half of the wavelength of the main noise frequency band. The noise energy will oscillate and dissipate between these adjacent convex parts. The double-sound-absorbing sandwich layer is mainly used to deal with the noise reduction of noise sources in multiple frequency bands. For example, the noise of the motor in the shell-breaking machine and the noise of the lotus seeds colliding with the machine are in different frequency bands. The sound-absorbing materials in the first sound-absorbing sandwich layer (925) and the second sound-absorbing sandwich layer (926) are respectively set with corresponding sound-absorbing materials for different frequency bands of noise to reduce the overall noise situation as effectively as possible.

[0039] In the present invention, the existing products can be used to process the shell-breaking machine, the edge-opening machine, and the shunt electric sieve machine used. Since the selection type is not the improvement point of the inventive concept of the present invention, the protection scope of the present invention should not be limited by this.

[0040] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and the protection scope of the present invention cannot be limited by this. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
