Description

Technical Field

[0001] The utility model belongs to the field of melon seed feeding equipment, and particularly relates to a melon seed raw material negative pressure lifting device. Background Art

[0002] The raw material of melon seeds mainly refers to sunflower seeds, which are also commonly known as sunflower seeds. During the melon seed processing, a negative pressure elevator is used to load and transport the melon seed raw materials to ensure the integrity of the melon seeds during the transportation process and ensure product quality.

[0003] When using the existing negative pressure lifting feeder, workers usually hold the feed hose and insert the suction end of the feed hose into the raw material to suck the material. Due to the weight of the feed hose, workers hold the feed hose for a long time, which increases the worker's labor intensity and easily leads to fatigue.

[0004] Therefore, we propose a melon seed raw material negative pressure lifting device to solve the above problems. Utility Model Content

[0005] In view of the problem that when using the existing negative pressure lifting feeder, workers usually hold the feeding hose. Since the feeding hose has a certain weight, workers hold the feeding hose for a long time, which increases the labor intensity of workers, the utility model provides a negative pressure lifting device for melon seed raw materials.

[0006] The utility model solves the technical problem by adopting the following solution: a melon seed raw material negative pressure lifting device, comprising a plate cart and a negative pressure loader body, the negative pressure loader body being fixedly mounted on the top of the plate, a feed hose being mounted on the feed end thereof, a hard suction head being provided on the suction end of the feed hose, and further comprising a vertical arm, a guide wheel and a drive assembly;

[0007] The bottom end of the vertical arm is welded and fixed to the top of the cart, and a sliding sleeve is provided on the vertical arm. The driving assembly is installed on one side of the vertical arm and connected to the sliding sleeve to drive the sliding sleeve to slide up and down along the vertical arm.

[0008] A fixed block is fixedly installed between the sliding sleeve and the guide wheel, and a feed hose passes through the guide wheel.

[0009] Preferably, the driving assembly includes an electric push rod, and a fixing seat and a connecting seat are respectively installed at both ends of the electric push rod. The fixing seat is welded and fixed to the side of the vertical arm, and the connecting seat is welded and fixed to the side of the sliding sleeve.

[0010] Preferably, it also includes an L-shaped seat and a sleeve, the sleeve is sleeved on the outside of the feed hose, one end of the L-shaped seat is fixedly connected to the sleeve, and the other end is provided with a circular hole, a U-shaped guide rod is provided in the circular hole, and the U-shaped guide rod is fixedly installed on the other side of the vertical arm.

[0011] Preferably, a counterweight is installed on the L-shaped seat.

[0012] Preferably, the vertical arm is made of square steel, and the U-shaped guide rod is made of steel pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model guides and supports the feed hose through the guide wheel, so that the suction head of the feed hose is inserted into the raw material to absorb the material. As the negative pressure feeder body continues to work, the raw material gradually decreases. By controlling the contraction of the electric push rod, the sliding sleeve, the fixed block and the guide wheel are slowly moved downward, and then the suction head of the feed hose is continuously in contact with the raw material to continuously absorb the material and continuously increase the negative pressure of the raw material. Therefore, there is no need for workers to hold the feed hose to absorb the material, thereby reducing the workload of workers.

[0015] 2. The utility model sets a counterweight block, so that after the guide wheel moves downward, the feed hose can be automatically pulled down under the action of the counterweight block, preventing the feed hose from being bent during the suction process, thereby avoiding the problem of obstructed suction.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See also Figure 1-3 The utility model provides a technical solution for a negative pressure lifting device for melon seeds raw materials:

[0022] Example 1:

[0023] according to Figure 1-3 As shown, it includes a cart 1 and a negative pressure loader body 2. The negative pressure loader body 2 is fixedly installed on the top of the plate, and a feed hose 6 is installed at its feed end. The suction end of the feed hose 6 is provided with a hard suction head, so that the suction head can be easily inserted into the raw material.

[0024] It also includes a vertical arm 31, a guide wheel 5 and a drive assembly. The vertical arm 31 is made of square steel. The bottom end of the vertical arm 31 is welded and fixed to the top of the cart 1, and a sliding sleeve 32 is provided thereon.

[0025] The driving assembly includes an electric push rod 42, and a fixing seat 41 and a connecting seat 43 are respectively installed at both ends of the electric push rod 42. The fixing seat 41 is welded and fixed to the side of the vertical arm 31, and the connecting seat 43 is welded and fixed to the side of the sliding sleeve 32. By controlling the extension and retraction of the electric push rod 42, the sliding sleeve 32 is driven to slide up and down along the vertical arm 31.

[0026] A fixing block 9 is fixedly installed between the sliding sleeve 32 and the guide wheel 5 . A feed hose 6 passes through the guide wheel 5 , and the feed hose 6 is guided and supported by the guide wheel 5 .

[0027] During specific use, the utility model provides a negative pressure lifting device for melon seed raw materials. First, the negative pressure loader body 2 is started, and the suction head of the feed hose 6 is inserted into the raw materials to suck the materials, thereby performing negative pressure lifting on the raw materials. As the negative pressure loader body 2 continues to work, the raw materials gradually decrease. The user controls the contraction of the electric push rod 42 to slowly move the sliding sleeve 32, the fixed block 9 and the guide wheel 5 downward, so that the suction head of the feed hose 6 continues to contact the raw materials, continuously sucks the materials, and continuously performs negative pressure lifting on the raw materials.

[0028] Example 2:

[0029] Based on the first embodiment, Figure 1 and Figure 2 As shown, it also includes an L-shaped seat 81 and a sleeve 83. The sleeve 83 is sleeved on the outside of the feed hose 6. One end of the L-shaped seat 81 is fixedly connected to the sleeve 83, and the other end is provided with a circular hole. A U-shaped guide rod 7 is provided in the circular hole. The U-shaped guide rod 7 is made of a steel pipe and is fixedly mounted on the other side of the vertical arm 31. The L-shaped seat 81 is guided by the U-shaped guide rod 7 so that the L-shaped seat 81 can move up and down smoothly.

[0030] A counterweight 82 is installed on the L-shaped seat 81. By setting the counterweight 82, after the guide wheel 5 moves downward, the feed hose 6 can be automatically pulled down under the action of the counterweight 82, preventing the feed hose 6 from being bent during the suction process, thereby avoiding the problem of obstruction of suction.
