Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural product processing tools, specifically to a bamboo shoot cutter. Background Technology
[0002] Harvesting bamboo shoots requires trimming and cutting off the roots, sometimes even the base. The large cut surfaces make them highly susceptible to microbial contamination, shortening shelf life. Traditional bamboo shoot cutters are limited to simple slicing. Since bamboo shoots naturally carry many microorganisms, slicing further increases the risk of contamination. To extend shelf life, disinfection or edible coatings can be used, such as weakly acidic electrolyzed water disinfection technology or chitosan coating technology. However, due to the large size of bamboo shoots and the high labor intensity, adding steps requires more manpower and increases processing costs. Utility Model Content
[0003] The purpose of this invention is to provide a method that can spray disinfectant and coating liquid onto the cut surface of bamboo shoots while cutting them, thereby reducing bamboo shoot processing steps and reducing processing costs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A bamboo shoot cutter includes a blade body and a blade holder that is hinged to one end of the blade body. The other end of the blade body is connected to a handle. The blade holder has a groove that fits into the blade of the blade body. An embedding block is embedded in the blade body. The embedding block has a multi-hole nozzle. The multi-hole nozzle is connected to a liquid storage tank through a pipe. The multi-hole nozzle is connected to the liquid storage tank by a sprayer; the cutter holder is equipped with a limiting block for fixing the bamboo shoot. An infrared sensor is provided near the blade of the blade body. The infrared sensor and the ejector are connected to a controller provided on the handle via a circuit.
[0005] Furthermore, the number of the multi-hole nozzles is set to 2, the liquid storage tank includes a disinfectant liquid storage tank and a coating liquid storage tank, and the number of the sprayers is correspondingly set to 2.
[0006] Furthermore, the embedding block is embedded in a slot on the blade body, and the embedding block and the slot are fastened together by screw rotation.
[0007] Furthermore, the number of the limiting blocks is two.
[0008] Furthermore, the two limiting blocks are set corresponding to the horizontal line of the tool body, and the two limiting blocks are set on both sides of the embedding block in the horizontal direction of the tool holder.
[0009] Furthermore, the embedded block is circular.
[0010] Furthermore, except for the central nozzle, the other nozzles of the multi-hole nozzle are inclined to the outer circumference and set at an angle of 30 to 45 degrees to the vertical direction of the blade body.
[0011] Furthermore, the blade body is provided with a groove through which a pipe can pass through which a multi-hole nozzle connects to a liquid storage tank, and the groove and the slot are connected.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a bamboo shoot cutter with a multi-hole nozzle installed above the conventional blade body. The multi-hole nozzle is connected to a disinfectant storage tank and a coating liquid storage tank respectively through an injector. When the blade body presses down to complete the bamboo shoot cutting, an infrared signal is triggered, and the controller opens the injector according to a set sequence, spraying the disinfectant and / or coating liquid into the bamboo shoot cut in a mist or liquid column. The bamboo shoot cutter structure of this utility model integrates "trimming and cutting-disinfection-coating" into one unit, avoiding extra labor and significantly extending the shelf life of bamboo shoots.

[0017] The orientations or positional relationships indicated by terms such as "upper," "lower," "middle," "inner," "outer," and "vertical" used in this utility model are based on the relative orientations or positional relationships shown in the accompanying drawings and are not intended to be absolute limitations on this utility model.
[0018] This utility model provides a technical solution that integrates "trimming and cutting - disinfection - coating" into one unit, and the aspects are described in detail below.
[0019] Example 1 This embodiment provides a bamboo shoot cutter, the specific structure of which is shown in the schematic diagram below. Figure 1As shown, the cutter includes a blade body and a blade holder hinged to one end of the blade body. The other end of the blade body is connected to a handle. The blade holder has a groove that fits into the cutting edge of the blade body. An insert block 3 is embedded in the blade body, and a multi-hole nozzle 6 is provided on the insert block 3. The multi-hole nozzle 6 is connected to a liquid storage tank through a pipe. An injector 4 is provided on the pipe connecting the multi-hole nozzle 6 and the liquid storage tank. A limiting block 5 for fixing bamboo shoots is provided on the blade holder. An infrared sensor 8 is provided near the cutting edge of the blade body. The infrared sensor 8 and the injector 4 are connected to a controller 9 provided on the handle through a circuit. A solenoid valve is also provided on the pipe connecting the injector 4 and the multi-hole nozzle 6. The solenoid valve is connected to the controller 9 through a circuit. When the cutter is not working, the solenoid valve is closed; when the cutter is working, the controller 9 sends a signal to the solenoid valve, and the solenoid valve opens and starts working.
[0020] To achieve both disinfection and coating functions, two storage tanks can be installed: a disinfectant storage tank 1 and a coating solution storage tank 2, containing, for example, weakly acidic electrolyzed water disinfectant and chitosan coating solution. One or two of these solutions can be added, or they can be replaced with antioxidants or other inhibitors. Two types of perforated nozzles 6 are also provided, integrated at intervals within the embedded block. Two injectors 4 are installed on the pipes connecting the disinfectant storage tank 1 and the coating solution storage tank 2 to the perforated nozzles 6. Alternatively, if the sole purpose is disinfection or coating, only one perforated nozzle 6 can be used for either operation.
[0021] The embedding block 3 is embedded in a slot on the blade body, and the embedding block 3 and the slot are fastened together by screw rotation. The blade body is provided with a pipe groove through which a multi-hole nozzle and a liquid storage tank can pass, and the pipe groove and the slot are connected. The slot is a circular structure, and the embedding block 3 is a circular structure that matches the slot and is fastened together by screw rotation.
[0022] Two limiting blocks 5 are provided, positioned corresponding to the horizontal line of the blade body and on either side of the embedded block 3 in the horizontal direction of the blade holder. Since the embedded block 3 is circular, the distance between the two limiting blocks 3 is greater than the diameter of the embedded block 3. When the blade body is lifted, the bamboo shoot is placed in the middle of the limiting blocks 3. To ensure that the cut bamboo shoot section 7 after cutting can fully contact the liquid sprayed from the multi-hole nozzle 6, the blade holder on one side of the limiting block can be raised on the horizontal plane near the groove. After cutting, under gravity, the bamboo shoot will tilt backward, naturally forming an angle and creating gaps. Simultaneously, the limiting blocks prevent the bamboo shoot from deviating too much from its position, allowing the multi-hole nozzle 6 to better spray liquid onto the cut bamboo shoot section 7.
[0023] Except for the central nozzle, the other nozzles of the multi-hole nozzle 6 are inclined outwards at an angle of 30 to 45 degrees to the vertical direction of the blade body. In this way, the liquid sprayed from the multi-hole nozzle 6 is fully sprayed onto the cut bamboo shoot section 7 to achieve the purpose of disinfection and / or coating.
[0024] The specific working process of this bamboo shoot cutter is as follows: When cutting bamboo shoots, press the handle of the bamboo shoot cutter down to its lowest point, so that the blade contacts the bottom of the groove on the blade holder. At this time, the infrared sensor 8 transmits a signal to the controller 9, which then sends a signal to activate the sprayer 4 and the solenoid valve. The sprayer 4 transports the liquid in the storage tank through a pipe to the multi-hole nozzle 6. The multi-hole nozzle 6 sprays the liquid from the storage tank onto the cut bamboo shoot section 7, initiating the spraying of disinfectant and / or coating liquid. Because the multi-hole nozzle 6, except for the central nozzle, is tilted outward at a 30-45° angle, the spraying area extends beyond the cut bamboo shoot section 7, achieving complete disinfection and / or coating effects. When the cutter is not in operation, the pipe connecting the sprayer 4 and the multi-hole nozzle 6...
