Description

Technical Field

[0001] The invention relates to a cooking and heating stove technology for rural use, in particular to an intelligent cooking and heating stove specially used for burning fruit tree branches. Background Art

[0002] At present, many places in northern rural areas of my country are vigorously developing fruit planting. Fruit trees need to be pruned every year. Except for some thick branches that farmers take home for burning, most of them are useless and are burned directly in the fields by farmers, which not only wastes resources but also pollutes the environment. Fruit farmers also have to buy coal every winter to solve the problem of cooking and heating. At the same time, it also increases the secondary pollution caused by burning coal. Summary of the invention

[0003] The invention aims to solve the technical problems of pollution and waste caused by burning fruit tree branches in rural areas, and provides an intelligent cooking and heating stove specially used for burning fruit tree branches.

[0004] The present invention is implemented by adopting the following technical scheme: an intelligent cooking and heating stove specially used for burning fruit wood branches, comprising a furnace body, which is divided into a storage box and a furnace; the storage box and the furnace are connected through a burner; the front end of the burner extends into the furnace, the end of the burner is located in the storage box and the end is provided with a pusher that can move back and forth inside the burner; air ducts are provided at the bottom and both sides of the burner, and the bottom of the front end and the bottom of the end of the burner are respectively provided with air supply holes and secondary air distribution ports connected to the air duct; air supply holes connected to the air duct are also provided on both sides of the front end of the burner; the longitudinal section of the pusher is an inverted U-shaped structure and the end is closed and used to connect external power; a push plate with air holes thereon is installed at the front end of the pusher; a feed port is provided at the upper part of the end of the burner and the feed port is located forward of the secondary air distribution port, and a fan connected to the air duct is installed at the bottom of the end.

[0005] Based on the current situation that burning of fruit tree branches in rural areas causes pollution and waste, the present invention uses pruned branches of fruit trees as fuel to replace coal, solving the problem of winter cooking and heating for fruit farmers in fruit tree planting areas. This can not only solve the pollution problem of open-air burning of pruned branches, but also solve the secondary pollution caused by burning coal, and at the same time save a lot of expenses for purchasing coal for fruit farmers.

[0006] The fruit branches used as fuel enter through the storage box and fall to the end feed port of the burner. The pusher pushes the fuel to the front under the action of external power and enters the furnace for combustion. The fan equipped with the burner is used to supply air to the burner (through the air supply hole), so that the fruit branches burn more fully and effectively reduce flue gas pollutants; there is an opening on the front push plate of the pusher, and the fan is also connected to the pusher through the secondary air distribution port, so that when the furnace is burning, the wind output by the fan blows to the front end of the burner through the secondary air distribution port and the opening on the push plate, which can effectively prevent the flue gas in the furnace from returning to the storage box, and can further supply air to the furnace. The longitudinal section of the pusher is an inverted U-shaped structure and the end is closed, so that its bottom can be connected to the secondary air distribution port. In actual operation, the pusher is staggered with the upper incoming materials under the action of external power, that is, when the upper incoming materials are coming, the pusher moves backward, so that the upper feed port at the end of the burner receives the fuel. After the fuel is in place, the pusher moves forward to push the fuel to the front end of the burner for combustion.

[0007] Furthermore, a connecting plate is used inside the storage box to form a container for accommodating feed, a feed plate that can move horizontally along the bottom of the container is horizontally installed at the bottom of the container, a drop opening is opened below the front end of the container, and the bottom of the drop opening is opposite to the feed opening of the burner; a motor is installed in the storage box below the container, and the output shaft of the motor is arranged upward and connected to a crank-connecting rod mechanism; the middle part of the crank-connecting rod mechanism is connected to the end of the pusher through a connecting rod; an opening running forward and backward is opened at the bottom of the container, and the upper part of the crank-connecting rod mechanism is connected to the bottom of the feed plate through the opening; the feed plate and the pusher have opposite strokes.

[0008] Put the fuel into the container, and the motor drives the feed plate and the pusher to run automatically through a crank-connecting rod mechanism, and the two have opposite strokes: when the pusher runs backward and exposes the top feed port at the end of the burner, the feed plate moves forward, pushes the fuel inside the container to the drop port and drops it to the feed port of the burner, and the crank-connecting rod mechanism drives the pusher to move forward, while the feed plate moves backward; the pusher moves forward and delivers the fuel to the front end of the burner for combustion.

[0009] Furthermore, a closed cover is movably installed at the blanking port; the closed cover is limited by a tension spring, and the tension spring cooperates with the feeding plate to realize the opening and closing of the closed cover.

[0010] The feed plate moves forward, pushes open the closed cover plate, pushes the fuel inside the container to the drop port and drops it to the feed port at the upper end of the burner. The crank-connecting rod mechanism drives the pusher to move forward, and the feed plate moves backward at the same time; the closed cover plate returns to its original position under the action of the tension spring to close the drop port to prevent smoke from entering the container in reverse.

[0011] Furthermore, a closed cover is movably installed at the blanking port; the closed cover is equipped with a power drive; the pusher is equipped with a travel switch; the travel switch and the power end of the closed cover are linked through a controller to achieve the coordination of the opening and closing of the closed cover and the action of the pusher.

[0012] Furthermore, a toothed anti-slip strip is fixed on the surface of the feeding plate.

[0013] Furthermore, the intelligent control system can realize automatic control of the fan and the motor, so as to adjust the fan air volume and the motor speed, and control the combustion process and the combustion temperature.

[0014] The stroke of the pusher is designed so that when it moves backward to the end, the push plate at the front end of the pusher is just located at the front edge of the secondary air distribution port. At this time, the fuel falls on the front end of the pusher to prevent the fuel from falling into the air duct.

[0015] The main innovations of the present invention are:

[0016] 1. A burner is added under the furnace to ensure more complete combustion and controllable temperature.

[0017] 2. The reciprocating feeding method is adopted, and a two-relay feeding system (feeding plate and pusher) is designed to ensure the continuity and adjustability of feeding.

[0018] 3. A special intelligent control system is designed to automatically match the feed amount and the air volume of the fan. Under various combustion conditions, the combustion is more complete and more environmentally friendly, avoiding the inconvenient adjustment of the original biomass furnace and the occasional substandard emissions.

[0019] 4. The intelligent control system of the stove has multiple combustion modes for users to choose from, including large, medium and small, and provides 24-hour constant temperature heating. The temperature is set by the user and can be remotely controlled by mobile phone.

[0020] 5. The stove is equipped with a storage box. Users can put the chopped fruit branches into the storage box at one time, and use it for 1-2 days, which reduces the trouble of users frequently adding materials in the past.

[0021] 6. A toothed anti-slip strip is added to the plane of the primary feeding plate to avoid material jamming and fuel overhead.

[0022] 7. A closed cover is designed at the blanking port (primary feeding channel port). Under the precise control of the travel switch and controller, it and the secondary feeder (pusher) can close the channel when no material is fed, thus preventing the occurrence of tempering.

[0023] 8. A secondary air distribution port is designed at the burner feed port (secondary feed port), which can make the combustion more complete and avoid the backflow of smoke and the emission from the storage box. BRIEF DESCRIPTION OF THE DRAWINGS
