Abstract
Description
Technical Field
[0001] The utility model relates to longan processing equipment, more specifically, it relates to a longan flesh remover. Background Art
[0002] Longan pulp is widely used as an ingredient in soups, and it has the effects of invigorating qi and blood, and relieving fatigue. The first step in making longan pulp is to separate the pulp from the fresh longan fruit. Existing longan shelling and core removal machines use a split-blade design for the core removal component. When the push rod connected to the split-blade moves downward, the blade heads of the multi-lobed blades first form a circular cutter head and penetrate the longan fruit stalk to a certain depth. The petals then open to a certain degree, and the open blades stretch the pulp around the stalk to achieve complete separation of the stalk and pulp. High-pressure air is then used to blow the longan kernel downward through the vent. However, during implementation, the pulp and the kernel are often blown away together. The main reason is that although the knife opens the flesh and performs a preliminary separation of the flesh and the core, the flesh has more juice and is relatively soft and tender, which also leads to less friction between the flesh and the knife, and the flesh is easy to fall off when blowing; and if there is a position where the opened flesh and the core are attached, under the action of the adhesion force between the two, the flesh is more likely to be blown out along with the flesh. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a longan flesh remover for the purpose of addressing the deficiencies in the prior art, which can more effectively separate the longan pulp from the core.

Detailed implementation mode
[0020] The following is a further description of the present utility model in conjunction with the embodiments, but it does not constitute any limitation to the present utility model. Any person's limited modifications within the scope of the claims of the present utility model are still within the scope of the claims of the present utility model.
[0021] Refer to Figure 1 - Figure 2 , a longan de-fleshing device of the present utility model includes a first seat body 40 and a second seat body 41. A fruit pit drilling needle 42 is movably arranged in the first seat body 40. Both ends of the fruit pit drilling needle 42 penetrate and extend to the outside of the first seat body 40 respectively. A driving wheel 50 is fixedly arranged at one end of the fruit pit drilling needle 42. A needle tail 43 is arranged at the other end of the fruit pit drilling needle 42. A threaded pit drilling section 44 is arranged at the end of the needle tail 43, which is used to drill into the fruit pit of the longan, fix the fruit pit, and make it rotate along with the fruit pit drilling needle. The second seat body 41 is fixedly arranged on one side of the first seat body 40. A push rod 45 is slidably installed in the second seat body 41. A connecting seat 46 is installed at one end of the push rod 45 close to the needle tail 43. A de-fleshing knife 47 extending to the periphery of the needle tail 43 is installed on the connecting seat 46, which is used to remove the longan pulp from the fruit pit, realizing the separation of the longan pulp and the fruit pit. Moreover, since the threaded pit drilling section 44 of the fruit pit drilling needle 42 drills into the fruit pit and fixes the fruit pit, when the de-fleshing knife 47 de-fleshes, the pulp can be easily removed and the fruit pit will not fall off, achieving a better separation effect, which is practical and reliable.
[0022] A positioning ring groove is opened on the driving wheel 50 of this embodiment, and a wear-resistant ring sleeve 51, such as a rubber sleeve, is sleeved in the positioning ring groove.
[0023] In this embodiment, de-fleshing knives 47 are arranged on both sides of the needle tail 43, and the two de-fleshing knives 47 are respectively fixed on the connecting seat 46 through connecting plates. Through the design of the two de-fleshing knives 47, the two sides of the pulp are evenly stressed when de-fleshing the pulp, and the pulp can be more effectively removed.
[0024] Preferably, the de-fleshing knife 47 is triangular, and the tips of the two de-fleshing knives 47 respectively deviate from both sides of the axis of the needle tail 43. That is, the tips of the two de-fleshing knives 47 are misaligned. Such a design enables the tips to be inserted into the pulp when de-fleshing the pulp, realizing the positioning of the pulp; under the pushing action of the push rod 45, the de-fleshing knife 47 will penetrate deeper and deeper into the pulp. However, due to the triangular shape of the de-fleshing knife 47, the deeper the de-fleshing knife 47 penetrates, the greater the resistance it receives. When the resistance is greater than the detachment force of the pulp from the fruit pit, the pulp will be effectively removed.
[0025] The longan pulp and the pit are closely attached. To more conveniently and thoroughly remove the pulp, a de - fleshing spring 48 is installed on the connecting seat 46 in this embodiment. The de - fleshing spring 48 bypasses the de - fleshing knife 47 and extends along the needle tail 43 towards the threaded pit - drilling section 44. The de - fleshing spring 48 can be attached to the needle tail 43. When the push rod 45 pushes the de - fleshing knife 47 and the de - fleshing spring 48 towards the threaded pit - drilling section 44, due to the good deformation characteristics of the de - fleshing spring 48 and the soft and tender longan pulp, it will move along the needle tail 43 and pass through the pulp to the pit. The pit is hard and its surface is smooth. Therefore, the de - fleshing spring 48 will move along the surface of the pit, thus forming a separating effect on the pulp, which is very beneficial to the de - fleshing of longan.
[0026] A push - rod bearing 49 is installed on the push rod 45 in this embodiment. Among them, the push - rod bearing 49 is composed of a rod body and a bearing. A positioning seat 57 for limiting the push - rod bearing 49 is installed on the second seat body 41. The push - rod bearing 49 is used to facilitate the external force acting on the push rod 45 to move it towards the threaded pit - drilling section 44.
[0027] In addition, a return spring 56 is provided between the connecting seat 46 and the seat body to realize the automatic reset of the push rod 45.
[0028] Preferably, a sound - damping rubber block 58 is embedded on the side of the positioning seat 57 in contact with the push - rod bearing 49 to buffer the moving push - rod bearing 49 during the reset process and reduce the noise generated by its collision.
[0029] Copper sleeves 55 are installed on both sides of the first seat body 40 in this embodiment. The fruit - pit - drilling needle 42 is movably inserted through the copper sleeves 55, and the fruit - pit - drilling needle 42 is rotatably connected to the copper sleeves 55. A positioning sleeve 53 and a force - adjusting spring 52 are sequentially sleeved on the fruit - pit - drilling needle 42 located in the first seat body 40. A locking sleeve 54 is provided on the side of the positioning sleeve 53 away from the force - adjusting spring 52, and the locking sleeve 54 is sleeved on the fruit - pit - drilling needle 42. A tightening bolt is screwed on the locking sleeve 54. Since the fruit - pit - drilling needle 42 is in hard contact when drilling into the pit, in order to protect the fruit - pit - drilling needle 42, a force - adjusting assembly composed of the locking sleeve 54, the positioning sleeve 53 and the force - adjusting spring 52 is adopted in this embodiment to realize the buffering effect when the pit and the fruit - pit - drilling needle 42 are in hard contact. By positioning the length of the force - adjusting spring 52 through the positioning sleeve 53 and locking it through the locking sleeve 54, the buffering degree of the fruit - pit - drilling needle 42 is adjusted to make it better adapt to the pit - drilling operation.
[0030] The working principle of the present utility model is as follows: An external driver, such as a rotating drive disk, is brought into contact with the wear-resistant sleeve 51 on the drive wheel 50, thereby causing the fruit pit drilling needle 42 to rotate. Then, a longan that has already had its shell broken is brought close to the fruit pit drilling needle 42 by means of a clamping device, and the threaded fruit pit drilling section 44 is inserted into the fruit pit. Next, the clamping device and the longan shell are removed, so that both the fruit pit and the pulp are located on the threaded fruit pit drilling section 44. Finally, the push rod 45 is moved by pushing the push rod bearing 49, and the movement of the push rod 45 will also drive the connecting seat 46, the flesh removing knife 47, and the flesh removing spring 48 to move in the direction of the threaded fruit pit drilling section 44. The flesh removing spring 48 first inserts into the pulp, then moves along the surface of the fruit pit. Immediately afterwards, the flesh removing knife 47 also inserts into the pulp, and when the insertion resistance is greater than the separation force of the pulp from the fruit pit, the pulp will be removed from the fruit pit. At this time, the pulp will be separated from the fruit stalk, thus achieving the separation of the pulp from the fruit pit.
[0031] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can be made, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
