[0032] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0033] First, the present invention can effectively break the blades without causing danger, thus solving the problem of safe breaking of blades, and has small size and simple operation.

[0034] The technical solution of the present invention solves many problems existing in the manual crushing blade device in the prior art in industrial applications and has achieved significant technical progress, which is specifically reflected in the following aspects:

[0035] 1. Improve crushing efficiency and effect

[0036] Existing manual crushing devices usually use a single type of blade, which results in poor crushing effect when processing blades of different types and thicknesses, and is prone to uneven crushing or difficulty in completely crushing the blades. The present invention can effectively adapt to the physical characteristics of various blades through a combination of blades of various shapes (such as long strips, sawtooth shapes, sharp knife shapes, etc.), and achieve more uniform and rapid crushing. In particular, the sharp knife-shaped blade design can provide stronger cutting force, significantly improving the overall crushing efficiency and effect.

[0037] 2. Easy and safe operation

[0038] Traditional manual crushing devices often lack reasonable ergonomic design, and are easy to slip or inconvenient to use during operation. Especially during long-term operation, users are prone to fatigue, which affects work efficiency. The present invention greatly improves the user's grip stability through the design of a serrated hand handle, ensuring that the hand will not slip during operation, thereby enhancing the user experience. In addition, the closed structure of the device and the circular through-hole design on the cover allow the blade to work in a closed environment, effectively preventing outsiders from contacting the blade, improving safety, and reducing the risk of accidental injury.

[0039] 3. Enhanced structural stability and reduced losses

[0040] Existing manual crushing devices often have loose or damaged parts after long-term use due to loose or loose assembly structures, which shortens the life of the device or requires frequent maintenance. The present invention ensures the tight fit between the various parts of the device through the mortise and tenon structure and the square long axis design, greatly enhances the structural stability of the overall device, and reduces the mechanical loss caused by looseness during operation. In particular, the matching design of the square long axis and the manual crank ensures that the torque transmission during operation is more uniform and stable, extending the service life of the equipment.

[0041] 4. Easy to disassemble for cleaning and maintenance

[0042] Existing devices are prone to accumulate residues after being used for a period of time, which makes cleaning difficult or inconvenient, and increases the user's maintenance costs. The present invention uses a detachable structure design, so that users can easily disassemble key components such as the hand handle and the annular sealed box, which is convenient for cleaning and maintenance inside the device, thereby improving the cleanliness of the device and reducing equipment failures caused by residues. This design greatly reduces the difficulty of daily maintenance of the device, making it more suitable for promotion in high-frequency industrial or household scenarios.

[0043] 5. Multiple application scenarios, wide adaptability

[0044] The application scope of traditional crushing devices is usually relatively single, and it is difficult to adapt to the needs of different application scenarios. The present invention, through the diversified design of the blade and the adjustable crushing structure, can not only be applied to conventional leaf crushing, but also is suitable for processing plant materials of different hardness and shapes. This makes the device have a wide range of application prospects in multiple fields such as agriculture, horticulture, and food processing, and solves the diverse needs of users in different scenarios.

[0045] In summary, the present invention successfully solves the shortcomings of existing manual crushing devices in crushing efficiency, ease of operation, structural stability and wide application scenarios through innovative structural design and multi-functional blade combination, and has achieved significant technological progress in industrial applications.

[0046] Second, as auxiliary evidence of the inventiveness of the claims of the present invention, it is also reflected in the following important aspects:

[0047] (1) The expected benefits and commercial value of the technical solution of the present invention after transformation are:

[0048] After the technical solution of the present invention is converted, the cost invested due to machine burnout can be significantly saved, and the operation is simple and safe, which greatly reduces the production cost, prevents damage to the structure and properties of the blade itself, has a significant crushing effect, and has significant commercial and ecological value.

[0049] (2) The technical solution of the present invention fills the technical gap in the industry at home and abroad:

[0050] There is no device for manually breaking blades in the prior art, and the present invention fills the blank of the device for manually breaking blades.

[0051] (3) Whether the technical solution of the present invention solves the technical problems that people have been eager to solve but have not been able to solve successfully:

[0052] Because the rotation speed is too fast under the action of electricity, the properties of the blades change and the excessive heat damages the machine, which is not conducive to the experiment. The only way is to cut it into pieces with scissors, but this process is time-consuming and labor-intensive and the crushing effect is not ideal. The present invention effectively solves the problem of blade crushing, has obvious crushing effect, and has significant economic benefits, ecological benefits and sustainable development benefits.

[0053] (4) The technical solution of the present invention overcomes technical prejudice: the present invention achieves significant comprehensive benefits at a relatively low cost, which is a major step forward in ensuring the structure and properties of the blade itself.

DETAILED DESCRIPTION

[0065] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0066] The following are two specific embodiments based on the present invention, showing the actual application effects of the device in different application scenarios:

[0067] Example 1: Efficient crushing of leaves from agricultural waste

[0068] In the agricultural production process, the processing of harvested crop leaves (such as corn, sugarcane, etc.) is often a tedious and time-consuming task. Traditional mechanical equipment is bulky and complicated to operate, and the manual crushing device has low crushing efficiency and is difficult to adapt to the processing needs of different types of leaves. The manual blade crushing device of the present invention performs well in this scenario and is particularly suitable for small and medium-sized farms or family farms.

[0069] 1.1 Application Scenario

[0070] When processing corn stalks and leaves, the agricultural operator puts the collected leaves into the annular closed box 2 of the present invention to ensure that they are completely covered within the crushing range of the rotating ring cutter shaft 4. The operator holds the hand handle 3 and uses the manual crank 6 to drive the square long shaft 41 to rotate.

[0071] 1.2 Effect performance

[0072] The blades of various shapes are designed, especially the sharp knife-shaped blade 45, which can easily penetrate the harder leaves, while the sawtooth blade 44 further tears the leaves and quickly breaks them into small pieces. Experimental data shows that the device can process about 300 grams of corn leaves in one minute, which is about 40% more efficient than the traditional manual crushing device. At the same time, the buffering effect of the silicone rubber pad on the blade reduces the sliding of the blade and improves the overall crushing efficiency.

[0073] Example 2: Refinement of horticultural waste

[0074] In urban gardening and home gardening, the disposal of discarded plant materials such as leaves and petals is also a common problem. Existing manual crushing equipment often fails to effectively crush the leaves because the leaves are too light or too thin. The manual crushing blade device of the present invention also performs well in handling these light materials.

[0075] 2.1 Application Scenario

[0076] The gardening operator puts the trimmed leaves, petals and other materials into the annular sealed box 2, and the blades of the rotating ring cutter shaft 4 are used for crushing. In order to avoid reducing the crushing efficiency of these lighter materials, the device provides a more stable operating feel through the serrated hand handle 32.

[0077] 2.2 Effect performance

[0078] During the rotation, the strip blade 43 and the sharp knife-shaped blade 45 alternately break the relatively weak petals and leaves into fine particles. Since the device is well sealed, no debris overflows during operation, reducing the cleaning work. Experiments show that the device can process about 200 grams of horticultural waste within two minutes, and the finished product has a high degree of refinement and is suitable for use as compost or other secondary processing materials.

[0079] These two embodiments demonstrate the flexible application of the present invention in different fields, especially in agricultural and horticultural waste treatment scenarios, where its efficient and stable performance greatly improves work efficiency and reduces the labor burden.

[0080] like Figure 1 As shown, a device based on manual crushing blades provided by an embodiment of the present invention includes, from bottom to top, a chassis 1, an annular sealed box 2, a hand handle 3, a rotating ring blade shaft 4, a cover 5 and a manual crank 6.

[0081] like Figure 2 As shown, the chassis 1 includes three raised circular holes 11 .

[0082] like Figure 3 As shown, the annular sealed box 2 includes three recessed circular holes 21 and a mortise and tenon structure 22 .

[0083] like Figure 4 As shown, the handle 3 includes a detachable structure 31 and a sawtooth-shaped handle 32 .

[0084] like Figure 5 As shown, the rotating ring blade shaft 4 includes a rectangular long axis 41 and a blade body 42.

[0085] like Figure 7 As shown, the cover 5 includes a circular through hole 51 and an annular groove 52 .

[0086] like Figure 8As shown, the manual crank 6 includes a square shaft 61 .

[0087] like Figure 6 As shown, the blade body 42 includes blades of different shapes, the two longer sides are strip-shaped 43, the other two sides are serrated 44, and a sharp knife-shaped blade 45 is respectively included between the strip-shaped and serrated blades. Compared with traditional blades, the blades can be effectively crushed.

[0088] The manual blade crushing device provided in the embodiment of the present invention realizes efficient blade crushing through a series of mechanical structures. The device includes a chassis, an annular sealed box, a hand handle, a rotating ring cutter shaft, a cover and a manual crank from bottom to top, and each component cooperates with each other to complete the blade crushing work.

[0089] First, the chassis 1 is used as the supporting base of the device, and is designed with three raised circular holes 11 for precise docking and fixation with the recessed circular holes 21 on the annular sealed box 2. This structure not only ensures the stability of the device, but also prevents the device from sliding or shifting during manual operation, providing a solid foundation for subsequent crushing operations.

[0090] The annular sealed box 2 serves to contain the blades. It adopts a mortise and tenon structure 22, which fits tightly with the raised circular hole of the chassis 1 and the detachable structure 31 of the hand handle 3. The mortise and tenon structure not only improves the sealing performance of the device, but also makes disassembly and assembly more convenient, so that the user can easily clean the broken leaves in the sealed box. In addition, the airtight design of the annular sealed box effectively prevents the spillage of blade debris during the crushing process, ensuring the cleanliness of the working area.

[0091] The design of the hand grip 3 enhances the convenience of operation of the device. The hand grip adopts a serrated hand grip 32, so that the operator can firmly hold the device to avoid the inconvenience of operation caused by sliding. Through the cooperation of the hand grip 3 and the rotating ring cutter shaft 4, the operator can easily apply force to rotate the blade to achieve the crushing of the blade. The hand grip also adopts a detachable structure to facilitate the disassembly and maintenance of the device.

[0092] The rotating ring blade shaft 4 is the core component of the device. Its square long axis 41 is rotated by the square axis 61 of the manual crank 6, driving the blade body 42 to rotate. The blade body 42 adopts a variety of blade designs, including a long strip 43, a sawtooth 44 and a sharp knife 45. Blades of different shapes can cope with blades of different materials and thicknesses, thereby improving the crushing effect. In particular, the sharp knife-shaped blade 45 can play a role in cutting and penetrating during the blade crushing process, greatly improving the crushing efficiency.

[0093] The function of the cover 5 is to seal the top of the device and ensure the safety of operation. The cover includes a circular through hole 51, which is convenient for inserting the crank handle 6 for manual operation, while ensuring that the blade rotates in a closed environment without causing danger to the outside world. The annular groove 52 of the cover fits tightly with the top of the annular sealed box 2 to ensure the sealing and stability of the entire device.

[0094] Finally, by turning the manual crank 6, the user can drive the square shaft 61, so that the rotating ring cutter shaft 4 drives the blade body 42 to rotate. The blades of different shapes cooperate with each other during the rotation process to cut, tear and crush the blades. Compared with traditional blades, the multi-shaped blade design of the device greatly improves the crushing efficiency, so that the blades can be crushed faster and more evenly, thereby meeting the processing requirements of different types of blades.

[0095] like Fig.10 As shown, an operation method based on manual crushing blades provided by an embodiment of the present invention includes:

[0096] S101, placing the material to be crushed into an annular sealed box;

[0097] S102, tightly cover the annular sealed box with a lid, and insert a manual crank through a through hole on the lid to connect with the rotating ring cutter shaft;

[0098] S103, manually rotating the crank handle to drive the blade to rotate and crush the material;

[0099] S104, after crushing is completed, remove the manual crank and the cover to take out the crushed material.

[0100] During the process of rotating the crank handle in S103 provided in the embodiment of the present invention, the long strip-shaped and serrated edges of the blade act on the material simultaneously, achieving different degrees of crushing effects.

[0101] A crushing method using an annular sealed box with a mortise and tenon structure provided by an embodiment of the present invention comprises the following steps:

[0102] (1) Fix the annular sealed box on the chassis through the mortise and tenon structure;

[0103] (2) Place the material into the annular sealed box, install the lid, and insert the manual crank into the through hole of the lid to connect it to the rotating ring cutter shaft;

[0104] (3) Rotate the manual crank, and the blade will crush the material in the annular sealed box;

[0105] (4) After crushing, remove the manual crank and cover and take out the crushed material.

[0106] A manual crushing method for positioning a chassis by a raised circular hole provided by an embodiment of the present invention comprises the following steps:

[0107] (1) Align the three raised circular holes on the bottom plate with the recessed circular holes on the bottom of the annular sealed box to fix the annular sealed box;

[0108] (2) Place the material into a ring-shaped sealed box, install the lid and insert the manual crank;

[0109] (3) Manually rotating the crank handle drives the blade to rotate in the annular closed box to crush the material;

[0110] (4) After crushing, remove the handle and cover and take out the crushed material.

[0111] During the crushing process of dry leaves, we found that although the traditional electric crusher has an ideal crushing effect, it causes too much damage to the machine. After the machine has been working normally for about a few minutes, it will become noticeably hot and have a noticeable burnt smell. The machine is also easily damaged, posing a major safety hazard to the laboratory.

[0112] In the process of using scissors to crush the dry leaves, it was found that although the leaves can be effectively crushed and the properties of the leaves themselves will not be destroyed, the crushing effect is very unsatisfactory, the crushing effect is poor, the crushing does not meet the requirements, and repeated crushing is required, which is time-consuming and labor-intensive.

[0113] Based on the above, first, it makes up for the potential safety hazards and damage to the blades during the crushing process of the electric crusher, and second, it makes up for the reality of poor crushing effect. This device combines the advantages of the two treatments, makes up for the shortcomings of the two treatments, and has a better blade treatment effect, meeting the needs of the experiment. The crushing effects of different blades are as follows Fig. 9 shown.

[0114] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any modifications, equivalent substitutions and improvements made by any technician familiar with the technical field within the technical scope disclosed by the present invention and within the spirit and principle of the present invention should be covered by the protection scope of the present invention.
