Description

Technical Field

[0001] This invention relates to the field of trolleys, and in particular to a hydraulic trolley for transporting broiler chickens. Background Technology

[0002] Based on the different cutting and cooking methods, frozen broiler chicken products can be simply divided into whole chicken products, cut products, prepared products, deep-processed products, and by-products. To meet production and processing needs, trolleys are often used to transfer these frozen products.

[0003] Because frozen chicken products often have residual blood on their surface, and some products need to be coated with ice, these frozen products tend to move around in the basket during transport, causing the cart's center of gravity to shift and potentially leading to tipping over. In addition, the frozen products not only tend to stick together, but they also freeze to the surface of the basket, affecting subsequent transfer work and making it difficult to separate the products. The purpose of this invention is to improve the existing cart structure to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a hydraulic trolley for transporting broilers, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: It includes a frame, a basket, a winding shaft, a suspension frame, and an induction coil. The basket is fixedly mounted on the frame, and an electromagnet is fixedly mounted at the bottom of the basket. The electromagnet refers to a device in the prior art that generates magnetism when energized, and its magnetism can be adjusted by changing the power of the electromagnet. The winding shaft is mounted on the side of the basket, and a flexible covering layer is wound onto the winding shaft. The flexible covering layer refers to a flexible and bendable material / fabric layer that serves a covering function, preferably made of non-absorbent or low-absorbent plastic material, which is not what the applicant intends to use. The protected technical content is not a necessary technical feature and will not affect the technical effect, so it will not be further explained. A metal mesh is set inside the flexible covering layer and the metal mesh attracts the electromagnet. The metal mesh is woven from metal wires (such as nickel alloy or low carbon steel) that can be attracted by the electromagnet. A channel is opened on the side of the basket, through which the flexible covering layer can pass. The suspension frame is set inside the basket and distributed along the height of the basket. A hook is set at the end of the flexible covering layer. The flexible covering layer can pass through the suspension frame and the hook can cooperate with the suspension frame. The induction coil is embedded in the side of the basket.

[0006] To optimize the above technical solution, the following measures are further taken: the flexible covering layer is laminated with polytetrafluoroethylene (PTFE) film on both sides. PTFE film has excellent chemical corrosion resistance and an extremely low surface friction coefficient, which can prevent ice from sticking together and also prevent damage to the flexible covering layer. In addition, the PTFE coating has good high temperature resistance and can be used in high temperature environments without being damaged by overheating of the metal mesh by the induction coil. The function of the flexible covering layer is to cover the frozen food and fix it, while separating the frozen food of different layers to prevent them from sticking together.

[0007] As a further improvement to the above technical solution, a limiting plate is also included. The limiting plate is located at the bottom of the basket and includes a tube, a spring, and a bimetallic strip. A through hole is formed on the limiting plate, and the tube is located within the through hole, forming a vertical sliding pair with the through hole. The spring is located at both ends of the tube, respectively abutting against the tube and the limiting plate. The bimetallic strip is located at the top of the tube and connected to it. The bimetallic strip refers to a sheet-like component made of two metals with different coefficients of thermal expansion, as described in the prior art. It achieves bending by utilizing the difference in the coefficients of thermal expansion of the metals at different temperatures. When the temperature changes, the bimetallic strip will bend and deform. In specific implementations, bimetallic strips of different materials can be selected according to actual needs, manufacturing costs, and other factors. Frozen products are placed on the tube directly below the limiting plate. The lowering of the tube will not affect the placement of frozen products, while the tube adjacent to the frozen products will press against the side of the frozen products to prevent them from sliding on the limiting plate, thus improving the stability of the frozen products during transportation. In addition, the temperature of the bimetallic strip on the tube adjacent to the frozen products will decrease due to heat transfer during contact with the frozen products. Due to the temperature change, the bimetallic strip will bend and deform, and the bent bimetallic strip can press against the side of the frozen products, improving the limiting effect of the tube on the frozen products and preventing the frozen products from shifting during the transfer. When the frozen products are transferred to the designated location, after the frozen products are removed from the limiting plate, the tube located below the frozen products will be reset by the action of the spring and extend out from the through hole. During the extension process, the tube can break through the thin ice formed on the surface of the limiting plate during the transfer of frozen products, preventing the thin ice from affecting the subsequent transfer of frozen products.

[0008] As a further improvement to the technical solution: a cavity is formed inside the limiting plate, and the opening of the cavity is connected to the channel on the side of the basket. Water, blood and other foreign objects that seep from the through hole on the limiting plate can be discharged through the cavity, preventing these foreign objects from accumulating at the bottom of the basket and causing the surface of the limiting plate to freeze, which would cause the frozen products to slide on the surface of the limiting plate.

[0009] As an improvement to the aforementioned technical solution: a scraper is provided on a channel, with the scrapers arranged in pairs on both sides of the flexible covering layer and the scrapers pressing against the surface of the flexible covering layer. When the flexible covering layer enters and exits the channel, foreign objects such as meat scraps and ice crystals attached to the surface can be scraped off by the scraper.

[0010] Furthermore, the induction coils are embedded and distributed along the height of the basket on the side. This distribution design ensures that the induction coils can fully cover the flexible covering layer inside the basket. In specific implementations, the induction coils and electromagnets can be powered by a rechargeable battery with a control panel mounted on the frame. The control circuit of the control panel can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0011] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: A. By using a flexible covering layer to secure frozen products, not only can the frozen products be prevented from shaking during transportation, but they can also be effectively prevented from sticking together during transportation. B. It can prevent frozen products from sticking to the bottom, making it difficult to separate the frozen products from the basket. The limiting plate has an automatic ice-breaking function after the frozen products are transferred, which can prevent thin ice from affecting the subsequent frozen product transfer work. C. The flexible covering layer surrounding the frozen products can reduce the leakage of cold air during the transfer process, and in conjunction with the limiting plate, it can prevent the frozen products from sliding during the transfer.

[0015] Example 2: Please refer to Figure 1-9 The present invention provides a hydraulic trolley for transporting broilers, including a frame 100, a basket 200, a winding shaft 300, a suspension frame 400, an induction coil 500, and a limiting plate 600.

A flexible covering layer 301 is wound on the winding shaft 300. The two sides of the flexible covering layer 301 are respectively composited with polytetrafluoroethylene film 305. A metal mesh 302 is provided inside the flexible covering layer 301 and the metal mesh 302 attracts the electromagnet 201. A channel 303 is opened on the side of the basket 200, through which the flexible covering layer 301 can pass. A scraper 306 is provided on one channel 303. The scrapers 306 are arranged in pairs on both sides of the flexible covering layer 301 and abut against the surface of the flexible covering layer 301. The suspension frame 400 is arranged inside the basket 200 and distributed along the height direction of the basket 200. The flexible covering layer 301 is provided with a hook 304 at its end. The flexible covering layer 301 can pass through the suspension frame 400 and the hook 304 can cooperate with the suspension frame 400. The induction coil 500 is embedded in the side of the basket 200, and the induction coil 500 is embedded in the side of the basket 200 and distributed along the height direction of the basket 200. The limiting plate 600 is located at the bottom of the basket 200. The limiting plate 600 includes a tube 601, a spring 602, and a hot bimetallic strip 603. A through hole 604 is formed on the limiting plate 600, and a cavity 605 is formed inside the limiting plate 600. The cavity 605 is open and communicates with the channel 303 on the side of the basket 200. The tube 601 is located inside the through hole 604 and forms a vertical sliding pair with the through hole 604. The spring 602 is located inside the tube 601, and its two ends abut against the tube 601 and the limiting plate 600 respectively. The hot bimetallic strip 603 is located at the top of the tube 601 and is connected to the tube 601.

[0016] Working principle: For Examples 1 and 2, when transporting frozen products, the frozen products are placed layer by layer in the basket 200. During the process, the flexible covering layer 301, which is wound on the winding shaft 300, is pulled out, passes through the suspension frame 400, covers the frozen products, and uses the flexible covering layer 301 to separate the frozen products of different layers (refer to the attached instruction manual). Figure 9 Since the frozen products of different layers are separated by the flexible covering layer 301, the frozen products of different layers are not prone to sticking together, which greatly facilitates the subsequent transfer of frozen products.

[0017] After the frozen food is placed, the electromagnet 201 is activated. Because the electromagnet 201 and the metal mesh 302 attract each other, the flexible covering layer 301 can tightly wrap the frozen food in the direction of the electromagnet 201 under the action of the attraction, which can firmly fix the frozen food and prevent the frozen food from slipping and falling during the transfer process, thus affecting the stability of the transfer process.

[0018] After the frozen products are transferred to the designated location, the induction coil 500 is activated. The induction coil 500 heats the metal mesh 302 inside the flexible covering layer 301 for a short time, which can melt the thin ice layer formed on the surface of the flexible covering layer 301. This prevents the thin ice layer from sticking to the flexible covering layer 301 and the frozen products, thus affecting the separation of the flexible covering layer 301 from the frozen products and the frozen products from each other. Then, the electromagnet 201 is turned off, and the frozen products can be transferred.

[0019] In Example 2, when the frozen product is placed on the limiting plate 600, the tube 601 located directly below the frozen product will move downward due to the pressure of the frozen product. At this time, the spring 602 is compressed and the tube 601 moves downward. The tube 601 adjacent to the frozen product is not squeezed by the frozen product, so it can limit the frozen product and prevent the frozen product from moving laterally on the limiting plate 600. This can improve the stability of the frozen product during the transfer process and prevent the frozen product from sliding during the transfer process.

[0020] When the frozen products are transported to the designated location, after the frozen products are removed from the limiting plate 600, the tube 601 located below the frozen products will be reset by the action of the spring 602 and extend out from the through hole 604. During the extension process, the tube 601 can break through the thin ice formed on the surface of the limiting plate 600 during the transport of frozen products, so as to avoid the thin ice affecting the subsequent transport of frozen products.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
