Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a jute stalk tip and stem separation harvester. Background Technology

[0002] In the industrial processing of jute, the precision of separating the stem tip from the stalk directly determines the efficiency of subsequent fiber extraction and product quality. As a bast fiber crop with both ecological and economic value, the stem tip and stalk differ significantly in composition and uses. Therefore, a separation harvesting technique is adopted. Furthermore, downstream separation harvesting typically requires the use of appropriate technologies and equipment tailored to the physical characteristics of jute. To adapt to jute of different qualities and growth stages, ensuring separation precision provides high-quality raw materials for subsequent fiber extraction and stem tip processing, thereby guaranteeing the efficient operation and product quality of the entire jute industrial processing.

[0003] In existing separation equipment, during the impurity removal stage, the moisture in the branches and leaves of the material is squeezed out after processing, making the material prone to sticking together and increasing the difficulty of subsequent cleaning. Therefore, a jute stalk tip and stem separation and harvesting machine is provided to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a jute stalk tip and stem separation harvester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A jute stalk tip and stem separating and harvesting machine includes a housing with a feed inlet at one end and a discharge outlet at the other. Sliding cavities are formed inside both sides of the housing. A piston rod is mounted inside each sliding cavity facing the base, with a piston plate and a spring fixedly connected to the piston rod. An air inlet pipe is installed inside each sliding cavity, and an air inlet is formed at the connection between the air inlet pipe and the outer wall of the housing. A one-way air inlet valve is fixedly connected to the air inlet. A flow cavity is formed at the top of the housing, and a second one-way air inlet valve is installed at the connection between the flow cavity and the sliding cavity. A cam groove is formed on the inner wall of the housing, and a cam is installed in the cam groove. The cam assembly abuts against the piston rod.

[0007] In order to blow air onto the processed material, preferably, the sliding cavity is provided with multiple air outlets, and multiple one-way exhaust valves are installed on the air outlets.

[0008] To enable more thorough processing and polishing of the material, preferably, a first set of rotating wheels is installed inside the housing, a belt assembly is fitted onto the first set of rotating wheels, and a polishing ring is fixedly connected to the first set of rotating wheels. A second set of rotating wheels is installed inside the housing, and a conveyor belt is fitted onto the second set of rotating wheels. The cam assembly is fixedly connected to the first set of rotating wheels for use.

[0009] For mutual communication, preferably, the sliding cavity and the flow cavity are connected by a one-way air intake valve.

[0010] Compared with the prior art, this utility model provides a jute stalk tip and stalk separation harvester, which has the following beneficial effects: it uses high-pressure gas to blow onto the sticky materials to separate them, preparing them for subsequent cleaning work and improving the efficiency of subsequent work.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1:

[0020] Reference Figure 1-6 A jute stalk tip and stem separating and harvesting machine includes a housing 1 with a feed inlet 101. Sliding cavities 3 are formed inside both sides of the housing 1. A piston rod 301 is mounted inside the sliding cavity 3 facing the base. A piston plate 302 is fixedly connected to the piston rod 301, and a spring 304 is fixedly connected to the piston rod 301. An air inlet pipe 305 is installed inside the sliding cavity 3, and an air inlet 102 is formed at the connection between the air inlet pipe 305 and the outer wall of the housing 1. A one-way air inlet valve 103 is fixedly connected to the air inlet 102. A flow cavity 306 is formed at the top of the housing 1, and a second one-way air inlet valve 303 is installed at the connection between the flow cavity 306 and the sliding cavity 3. The inner wall of the housing 1 is provided with a cam groove 307, and a cam 4 is installed in the cam groove 307. The cam assembly 4 abuts against the piston rod 301. Multiple air outlets 2 are provided in the sliding cavity 3. Multiple one-way exhaust valves 201 are installed on the air outlets 2. A first set of rotating wheels 401 is installed inside the housing 1. A belt assembly 402 is sleeved on the first set of rotating wheels 401. A grinding ring 405 is fixedly connected to the first set of rotating wheels 401. A second set of rotating wheels 403 is installed inside the housing 1. A conveyor belt 404 is sleeved on the second set of rotating wheels 403. The cam assembly 4 is fixedly connected to the first set of rotating wheels 401 for use. The sliding cavity 3 and the flow cavity 306 are connected through the second one-way air inlet valve 303.

[0021] During operation, the operator feeds the harvested raw materials into the housing 1 through the feed inlet 101. After the machine is powered on, the first set of rotating wheels 401 and the second set of rotating wheels 403 begin to rotate synchronously. At this time, the cam assembly 4 is driven by the first set of rotating wheels 401. The raw materials are squeezed and ground by the grinding ring 405 on the first set of rotating wheels 401 for separation. During this rotation, the cam 4 continuously pushes the piston rod 301. The piston rod 301 drives the piston plate 302, which is pushed by the cam 4 and compresses the spring 304. After the cam 4 passes its apex, the spring 304's elasticity drives the piston rod 301 to return to its original position, and then it reciprocates in the sliding cavity 3. The sliding cavity 3 inside the machine is connected to the air inlet pipe 305. When the piston rod 301 reciprocates, it continuously draws air from the air inlet pipe 305 and the air inlet 102 and sends it to the flow chamber 306. Because the sliding chamber 3 and the flow chamber 306 opened on both sides of the machine are interconnected, and the flow chamber 306 is provided with an air outlet 2, the one-way exhaust valve 201 installed on the air outlet 2 can continuously blow air into the housing 1 when the machine is running. The high-pressure gas generated is continuously blown towards the sticky impurities that are ground out during the machine processing, which can blow the sticky impurities away from the processed material stem. The ground material falls onto the conveyor belt 404, and the conveyor belt 404 is driven by the second set of rotating wheels 403 to start moving and the material is sent out from the discharge port 104.

[0022] The machine uses high-pressure gas to blow onto sticky materials, causing them to separate and preparing them for subsequent cleaning work, which can improve the efficiency of subsequent work.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
